LEP1DOPTERA LYCAENIDAE THECLA CRYSALUS. 777 



may be found during the months of June and July. Seventy-three speci- 

 mens were taken. 



In this species, the number of ocelli above and the ornamentation of 

 the secondaries below are quite variable. In some specimens, there is but a 

 single ocellus on the primaries ; in others, four are present on the fore 

 wings, and five upon the secondaries. On the under side of secondaries, 

 some indication of the median band may generally be seen, but in some 

 specimens the hind wings below are uniformly mottled with blackish trans- 

 verse streaks ; these about equally dividing the surface with the white ground 

 color. In others, these streaks may become pale ochraceous, and quite indis- 

 tinct on the outer half of the wing. 



CHIONOBAS CHRYXUS, Hewitson. 

 Chionobas Ghryxus, SCUD., Proc. Ent. Soc. Phila., 1865. 



This Chionobas was found in more elevated regions than C. Uhlerii, 

 still keeping, as a rule, below timber line. It was brought by the expedi- 

 tion from Gray's Peaks. My first specimens were taken July 8 on the 

 Arkansas divide, in company with Colias Meadii, and other rare mountain 

 species. It "was not very uncommon by the road side. In the course of the 

 day, eleven specimens were taken. One female was found with an egg 

 adhering to the abdomen ; this was white, melon-shaped, and considerably 

 larger than the egg of Satyrus Nephele. 



C. Chryxus seems to be found in small numbers through all the mountain 

 region around the South Park, rarely, however, below 9,000 feet. None 



were seen after July. 



THECLA, Fabr. 



tTHECLA HALESUS, Cramer. 

 Thecla Juanita, SCUD., Proc. Bost. Soc. Nat. Hist., 1868. 



Brought in by the expedition of 1871. It is a subtropical species, and 

 occurs from Florida to California. 



THECLA CRYSALUS, Edw. 

 Thecla Crysalus, EDW., Proc. Am. Ent. Soc., 1873. 



A few specimens of this perhaps the most beautiful of our Theclas 

 were brought from Lake Pass, Colorado, by the Allen expedition of 1871. 

 They were taken early in July.
