THE CACTUS-FEEDING PHYCITINAE HEINRICH 401 



Female. — Similar to the male in color and markings except that 

 hind wing is more or less suffused with smoky fuscous beyond the 

 base, especially along the veins and termen. 



Alar expanse, 33-44 mm. 



Genitalia (fig. 77) with sclerotized plates on dorsal wall of ductus 

 bursae behind the genital opening well developed, but with opposing 

 ventral sclerotized plate absent, replaced by minute scobinations ; 

 ductus bursae shorter than in other Gactohrosis species; bursa copu- 

 latrix not entirely smooth, having a few weak scobinations toward 

 ductus. 



Type. — In United States National Museum. 



Type locality. — Eureka, Utah. 



Food plants. — Echinocereus 7i(/klissi'mus (Engelmami), E. pecti- 

 natus (Scheidweiler), and probably a number of other species of 

 Echinocereus. 



Distributimi. — United States: Utah., Eureka (Aug., Sept.), Divi- 

 dend (Sept.) ; California., San Gorgonio Pass (July) ; Arizona., Tuc- 

 son (Apr., July), Texas., Brewster County (July, Aug.), Alpine 

 (Apr.). Mexico, Mexico City (National University, male reared 

 from E. pectinatus., June 3, 1931). 



Eighteen specimens examined. 



Remarks. — In a number of respects (its shorter vinculum and 

 ductus bursae, its weak abdominal tufts, and its partially scobinate 

 bursa copulatrix) this species fits badly into Gactolyvosis. Eventually 

 it may need a separate generic designation; but this had better be 

 postponed until the life histories of the other species of Gactohrosis 

 are more fully known. 



The fore wing markings of strigalis resemble those of Eremberga 

 leuconips (Dyar). The latter, however, is easily distinguished by its 

 squamous maxillary palpi.
