THE CACTUS-FEEDING PHYCITINAE — HEINRICH 391 



me moths of odiosella {= dare f acta) ^ when alive, have a decidedly- 

 greenish tint, while living adults of fuscomaculella { = heliophila) 

 are uniformly "gray" with no suggestion of green, and that this dif- 

 ference corresponds with the distribution of the two forms; namely, 

 southeastern Texas and eastern Mexico as against the coastal region 

 of southern California. Such differences seem to indicate geographical 

 races, but, in view of the similarity of the two forms otherwise, not 

 distinct species.

Female. — Palpi, head, thorax, and fore wing dark grayish fuscous, 

 lightly sprinkled with white. Fore wing with some white dusting on

 medial and subterminal transverse lines whitish, bordered with black 

 or blackish fuscous, the pattern as in lucidalis and odiosella; discal 

 spot at end of cell curved, black ; between this and subterminal lines 

 one or two small, obscure, blackish dots; upper and lower veins of 

 cell faintly outlined by white scales ; a row of black dots along termen 

 at or close to the vein ends; cilia pale ocherous-fuscous. Hind wing 

 white with a narrow fuscous shade along termen ; cilia white, with a 

 fuscous subbasal line. 



Alar expanse, 28 mm. 



Genitalia (figs. 63-63a) with signum a small cluster of two or three 

 more or less fused and minute spines; bursa copulatrix partially 

 wrinkled (in the region of the signum) ; ductus bursae of moderate 

 length, finely scobinate toward bursa. 



Type. — In United States National Museum. 



Type locality. — Oceanside, Calif. 



Food plant. — Opuntia {Cylindropuntia) sp. 



Remarks. — Kjiown only from the unique female type, reared Au- 

 gust 1924 from larva in a Cylindropuntia., presumably feeding in the
