LEPIDOPTERA— LYOAENIDAE— THECLA MOPSUS. 779 



this, as well as the next patch on either side, is surmounted by a black

Body gray-brown above, beneath dark brown, with white hairs inter- 

 spersed ; the abdomen yellow-gray ; legs dark brown and white ; palpi 

 white, fuscous at tip ; antenna? annulated white and black ; club black, 

 tipped with pale fulvous. 



From 2 <? taken by H. W. Henshaw at Fort Wingate, Ariz., July, 1874. 



This species is allied to Castalis and Smilacis, being of similar size and 

 shape. On the upper side deeper red than Castalis; on the under side there 

 is much resemblance to Castalis in the shades of color and in the common 

 band. But this last is much less irregular than in Castalis, in which the 

 separate spots that compose the band are not confluent, and the two in the 

 median interspaces are much behind the line of the rest. In Siva, the line is 

 scarcely broken at this point, and is confluent. In Castalis are two conspic- 

 uous white spots nearer base of secondaries, which are not represented in 

 Siva. Smilacis is fuscous on upper side, and below is most like Castalis; 

 the band being very irregular and the two spots next base appearing. —

t THECLA CALIFORNICA, Edw. 



Thecla Cali/ornica, Edw., Proc. Acad. Nat. Sci. Phila., 1862. 



T. Californica resembles T. Cygnus very closely. In the latter, however, 



the stigma upon the primaries of the male ends in a blunt point ; in the 



former, it is rounded. The species was taken by the expedition in Southern 



Utah. 



THECLA S^PIUM, Boisd. 



Thecla Scepium, Morris, Syn. Am. Lep., 99. 



The first specimens seen were near Apex Gulch, Colorado, August 3. 

 In the course of about two hours, fifty specimens, mostly females, were 

 taken on the Goldenrod flowers (Solidago). No specimens were taken else- 

 where. 



THECLA MOPSUS, Hiibner. 



Thecla Mojjsus, Harris, Insects Injurious to Vegetation. 



A few specimens were taken at Apex Gulch with T. Scepium, and 

 others were obtained toward the last of August at Bailey's ranch, on the 

 South Park road.
