A NEW SPECIES OF HYPOPTA. 



BY HARRISON G. DYAR, NEW YORK. 



An interesting species of Hypopta has been sent to me by Mr. 

 T. D. A. Cockerell, from Las Cruces, New Mexico. It appears to be un- 

 described. 

 Hypopta theodori, n. sp. 



White ; head white, the large eyes black ; pectinations of antennas 

 blackish ; collar white ; thorax clothed with light gray hairs, mixed with 

 white ; legs heavily clothed, obscurely annulate with gray near the tips. 

 Abdomen banded with clouded pale gray 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 dis- 

 tinct toward the apex on costa. In the interspaces, and beyond the cell 

 from vein 2 to apex of wing, is a series of diffusely clouded, strigose, 

 pale purplish-gray patches, separated by a white space along the veins, 

 and divided alsotransversely 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-gray, 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 gray, rather 

 more diffusely than on upper surface. Costae of both wings with a row 

 of gray dots and terminal dots on both. Fringe white, as above. Ex- 

 panse, 29 mm. Length of body, 15 mm. 



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

 Mexico, " a dry, flat, sandy locality, with hardly any trees but cottonwood 

 and cultivated fruits. Its altitude above the sea is 3,800 feet." I have 

 named the species in honour of Mr. Cockerell, whose labours in the ento- 

 mological field are worthy of general recognition.
