firm, with very rigid shafts; longer lower tail-coverts extraordinarily developed, resembling true rectrices, extending beyond the tail proper, and appearing as a second tail, of rounded form, below the upper forked one!

Affinities.-This genus is very similar to Ciconia, but differs very decidedly in the character of the tail and its lower coverts, which assume a form and relationship altogether peculiar, so far as this group is concerned, unless matched by some of the several Old World forms which I have not seen. In Ciconia, the tail is of normal form, being rounded, the feathers broad and moderately firm, with the longer lower coverts soft and loose, and falling considerably short of the end of the rectrices. In this genus, however, both the tail and its lower coverts are so modified that it is at first almost impossible to tell which is the true tail; indeed, all authors whom I have been able to consult in the matter describe the black stiff feathers as the upper coverts, and the longer, softer, but still firm feathers beneath them, with a rounded posterior outline, as the tail; in fact, it was only after the most careful examination, that I determined the former to be the true rectrices!

ART. X.-NOTICE OF THE BUTTERFLIES COLLECTED BY DR. EDWARD PALMER IN THE ARID REGIONS OF SOUTHERN UTAH AND NORTHERN ARIZONA DURING THE SUMMER OF 1877.

BY SAMUEL H. SCUDDER.

Although the collection of Dr. Palmer is not a large one, embracing only forty-one species, it adds considerably to our knowledge of the geographical distribution and variation of the species, and even contains several new forms; it seems worthy, therefore, of notice as a whole, and particularly since the special localities visited are off the ordinary route of travel.

The localities mentioned below are the following: *

Beaver Mountains, Utah; the mountains about Beaver, Utah.
Paragoonah, Utah; 25 miles west of south of Beaver.

Bear Valley, Utah; a valley about 20 miles nearly south of Beaver, surrounded by spurs of the Wahsatch Mountains.

Pine Mountains, Utah; "20 miles north of St. George, Utah." Mountain Meadows, Utah; the scene of the noted emigrant massacre, about 30 miles north of St. George. It is an elevated, meadow-like spot, surrounded by mountains.

St. George, Utah; at the extreme southern limit of the Territory. Mount Trumbull, Utah; "60 miles east of St. George"; a slight elevation, in a rough, volcanic, mountainous region. The specimens were collected about a spring at the base.

Beaver Dam, Arizona; 25 miles west of south of St. George, on Virgin River. The most desert-like region visited. Dr. Palmer remarks that in the arid sections of Southern Utah and Northern Arizona, where plants appear only at widely separated localities, the butterflies fly much more swiftly than usual, and are very shy. The easiest place of capture is in the vicinity of springs or pools of rain-water.

Mokiak Pass, Arizona; "20 miles east of south of St. George"; a pass in mountains between St. George and Juniper Mountains, in a very broken and rough volcanic region.

Juniper Mountains (or Cedar Ridges), Arizona; a region much like the previous, "40 to 50 miles east of south of St. George", covered * Most of these localities may best be found in the Atlas of Wheeler's Survey for 1874; but Pine Mountains, Mount Trumbull, Mokiak Pass, and Juniper Mountains do not appear. In these latter cases, I have mentioned the distances given me by Dr. Palmer; although in the other cases the distances he gave me invariably proved too great.

with juniper-trees and scrub-pines. It is about 20 miles east of south of Mokiak Pass.

Neominois dionysus, nov. sp.-Differs from N. ridingsii, to which it is closely allied, by its larger size, its more cinereous tints, and by the much more produced serrations of the margins of all the banded markings of the hind wings. In most specimens, this latter feature is much more conspicuous below than above, and is generally more noticeable than elsewhere in the interspace beyond the cell, the tooth of the black line which crosses the middle of the wing sometimes extending one-third the distance to the margin of the wing. Where specimens of the two species approach each other in the sharpness and length of the serrations, this species can always be distinguished by its larger size, lighter tone, and the lesser contrast of its darker and paler markings. The lower median interspace of the hind wings bears a small, oval, longitudinal spot on the upper surface next the outer limit of the broad, submarginal, pale band, smaller and even obsolete in the male. The same spot occasionally appears, but less conspicuously, in the female of N. ridingsii. Although Nevada specimens of the latter appear to be larger than those from Colorado (cf. Edwards's description of Sat. stretchii), iu so far approaching this species, Satyrus stretchii appears to be a true synonym of N. ridingsii, being in other respects no closer to the species here separated.

Expanse of wings: 8, 48-51mm; 55-58.5mm; 7 8, 4 . Juniper Mountains, June 4; Mount Trumbull, June 7–10.

Canonympha ochracea Edw.-Bear Valley, July 4; Paragoonah, July 10-12.

Anosia berenice (Cram.) Scudd.-St. George, April-May.

Basilarchia weidemeyeri (Edw.) Grote.-Bear Valley, July 4; Beaver Mountains, July 18-20.

Papilio antiopa Linn.-St. George, April-May; Mokiak Pass, April 28-30.

Vanessa cardui (Linn.) Ochs.-Paragoonah, July 10-12.

Argynnis nevadensis Edw.-Beaver Mountains, July 18–20.

Argynnis rupestris Behr.-Beaver Mountains, July 18-20. This but terfly does not appear to have been recorded before from without the limits of California.

Argynnis coronis Behr.-A single female was taken by Dr. Palmer on the Beaver Mountains, July 18-20, which differs from specimens sent me by Mr. W. H. Edwards, under this name, in the darker color of the upper surface of the wings, the brown becoming nearly black and the fulvous deepening to tawny, and in its smaller size, since it only expands 50mm. Beneath, the markings are precisely the same, excepting that

the extra-mesial row of silver spots on the hind wings is distinctly followed apically by a row of small, bordering, olivaceous spots; the tints are all a little darker; the submarginal band of the hind wings has become of a saffron hue, and the inner margin of the same wings is broadly sprinkled with green, a tint which appears more or less in other parts, and especially on the costal margin of the hind wings and the outer margin of the front wings. Notwithstanding these differences, and the fact that A. coronis has not before been detected out of California, there seems to be no doubt that the specimen should be referred as above.

Lemonias anicia (Doubl.-Hew.) Scudd., var. editha.-Mokiak Pass, April 28-30 or June 2; Pine Mountains, May 12; Paragoonah, July 10-12; Beaver Mountains, July 18-20.

Lemonias helcita (Boisd.) Scudd.-Five specimens (4, 19) were taken at Mokiak Pass, April 28–30 (or June 2), and Pine Mountains, May 12, and are the first perfect specimens I have been able to study. It seems to be abundantly distinct from L. palla, of which Mr. W. H. Edwards considers it only a variety. All the specimens agree very closely, and differ from L. palla on the upper surface of the wings in the decidedly paler and duller ground-color; the middle of the outer half of both wings is crossed in L. palla by a pair of almost exactly similar and distinct, parallel, black bands; the outer only is distinct in L. helcita (and is much narrower than in L. palla,) the inner being much fainter and almost or quite obsolete in the middle of its course; the pale mesial band of the hind wings of L. palla is scarcely paler than the other parts of the wing in L. helcita. Beneath, similar differences occur; the fulvous tints are decidedly paler in L. helcita, as above, while the straw-yellow which marks the lunules and other pale spots in L. palla is replaced by nacreous-white; besides, the hind wings further differ in the much greater extent of the pale markings, which are not so compactly massed as in L. palla; the outer of the two cell-spots especially is much larger than in L. palla, while the cinnamon band of L. palla, embraced between the mesial band and the submarginal lunules, is reduced to a narrow series of four or five dull red, round spots, indistinctly margined with pale scales; the outer reddish margin of L. helcita is not more than half so broad as the deeper-colored border of L. palla. The species has not before been recorded from either Utah or Arizona.

Schoenis arachne (Edw.) Scudd.—Bear Valley, July 4. These are the first specimens of this species I recollect seeing. Although both Edwards and Mead place it as a synonym of Edwards's earlier-published Mell. minuta, there appear to me to be such differences between the descriptions and figures of the two that it would be well to retain them as distinct until direct comparison of a series of specimens from Texas and Arizona can be made.
