256 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



Phyciodes pratensis (Bebr.) Kirb., var. campestris. — Piue Mountains, 

 May 12 ; Mount Trumbull, June.7-10 ; Bear Valley, July 4 ; Paragoonah, 

 July 10-12. 



IncisaUa augustus (Kirb.) Min., var. irioides. — A single male was 

 taken at Mount Trumbull, June 7-10. It is a good deal rubbed, but is 

 sufficiently well preserved to show that it differs from California speci- 

 mens in having the apical half of the wings beneath very nearly of the 

 same dark slate-color as the upper surface, being almost wholly desti- 

 tute of any ruddy tint. It has never before been taken in this region. 



Uranotes melinus (Hiibn.) Scudd. — St. G-eorge, April or May. 



Thecla siva Edw. — Juniper Mountains, May 1-2 or June 4; Para- 

 goonah, July 10-12. 



Evercs amyntula (Boisd.) Scudd. — Paragoonah, July 10-12. 



Cupido pheres (Boisd.) Kirb. — The specimens collected by Dr. Palmer 

 (8^,49) are the first recorded from this region, and are more uniform in 

 appearance than appears to be common; they also differ in certain, 

 respects from California specimens. The upper surface of the male, for 

 instance, is of a deeper violet and the dusky margin is narrower upon 

 the front wing ; in the female, the colors of the upper surface are more 

 contrasted; and beneath, in both sexes, the extra-mesial row of spots 

 on the front wings are almost uniformly well defined, moderately large, 

 rounded, and somewhat regularly curved ; while the same series on the 

 hind wings are white, generally with a central, subobsolete, black dot, 

 although in this respect the females vary considerably. Mountain 

 Meadows, May 14-18 j Mount Trumbull, June 7-10 j Beaver Mountains, 

 July 18-20. 



Cupido scepiolus (Boisd.) Kirb. — The single male obtained at Bear 

 Valley, July 4, is of an unusually small size (expanse of wings, 30"^™), 

 with heavy markings beneath, as usual in California specimens. 



Cupido Jieteronea (Boisd.) Kirb. — Beaver Mountains, July 18-20. 



Eusticus hattoides (Behr) Scudd. — Juniper Mountains, May 1-2 or 

 June 4. Xever before found in this section. 



Eusticus melissa (Edw.) Scudd. — Bear Valley, July 4; Beaver Mount- 

 ains, July 18-20. 



Brephidlum exile (Boisd.) Scudd. — St. George, April-May; Beaver 

 Dam, April 20-28 ; Juniper Mountains, May 1-2. 



Chalceria sirius (Edw.) Scudd. — Two males taken on the Beaver 

 Mountains, July 18-20, are too rubbed to determine positively whether 

 they belong to this species or to G. rtibida, although they appear more 

 to resemble the former. 



Epidemia helloides (Boisd.) Scudd.— Juniper Mountains, May 1-2 or 

 June 4 ; Bear Valley, July 4 ; Paragoonah, July 10-12.
