AMERICAN LEPIDOPTERA. Ill 



lunules which are not quite confluent; on secondaries slightly wavy, 

 and confluent; on the basal side of this band the fulvous ground color 

 is deeper than elsewhere, and on secondaries several of the white spots 

 are edged by a line of black scales ; between the band and base no 

 spots or markings on either wing; secondaries have the hind margin 

 edged with white, the outer angle fulvous ; the interspaces along the 

 margin between the discoidal nervules and anal angle gray, caused by 

 black scales on a white ground ; on the lower median interspace above 

 the gray patch is a rounded blackish spot on ferruginous ground, and 

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

 lunule; anal angle 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 ; antennae annulated white and black ; club black 

 tipped with pale fulvous. 



From 2 S taken by Mr. Henshaw at Wingate, Arizona, July, 1874. 



This species is allied to Casfah's and Smilacis, being of similar size 

 and shape. On the upper side deeper red than CasfnNs, 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 conspicuous white spots nearer base 

 of secondaries which are not represented in JSiva. Smilacis is fuscous 

 on upper side, and below is most like Castalis, the band being very 

 irregular and the two spots next base appearing.
