Hypopta theodori Dyar. Can. Ent., XXV, p. 220 (1893). 



"White; head white, the large eyes black; pectinations of antennae black- 

 ish ; collar white ; thorax clothed with light grey hairs, mixed with white ; legs 

 heavily clothed, obscurely annulate with grey near the tips. Abdomen banded 

 with clouded pale grey above, white below. Fore wings white, the basal half 

 immaculate except for a few minute black dots along the costal edge and internal 

 margin. These dots become more distinct toward the apex on costa. In the 

 interspaces, and beyond the cell from vein 2 to apex of wing, is a series of dif- 

 fusely clouded, strigose, pale purplish-gray patches, separated by a white space 

 along the veins, and divided also transversely in a somewhat irregular manner. 

 Along the discal cross-vein and near the origin of the discal and subcostal 

 venules, the colour of these markings shades into blackish, where they abruptly 

 terminate. Terminally, they become more obscure and strigose, leaving the 

 fringe white. Hind wings similarly marked, but the markings are entirely pale 

 purplish-grey, and form a series of intervenular clouded spots in three or four 

 indistinct rows between middle of wing and margin. Beneath the markings are 

 repeated in a somewhat leaden grey, rather more diffusely than on upper sur- 

 face. Costae of both wings with a row of grey dots and terminal dots on both. 

 Fringe white, as above. Expanse, 29 mm. Length of body, 15 mm. 



Described from a single example taken July 16, at Las Cruces. New Mexico." 



This species varies considerably in the depth of markings and in 

 size; our smallest specimen expands 21 mm., our largest 29 mm. In 

 some specimens the markings of secondaries are extended, so that the 

 whole wing presents a dark greyish appearance. This is notably the 

 case in the $ specimen before us.

"Body parts sordid white, shaft of antennae white, pectinations blackish. 

 Fore wings white, with a faint brownish tinge which becomes marked beyond 

 the cell, predominantly in two obscure parallel transverse lines, the outer of 

 which is subterminal ; along the inner margin, occupying nearly all the space 

 enclosed by vein la, except at base, is a patch composed of mixed brownish 

 black and pale ocherous scales. This patch is obscurely divided in a strigose 

 manner by the white ground color. Fringes white, very faintly spotted with 

 ocherous brown. Secondaries light-gray, whitish at abdominal margin and 

 fringe, showing faintly the markings of underside. Below both wings are 

 blackish gray, fading to white along the internal margin, but thickly covered
