 Ellopia punctata (Hulst) Barnes and McDunnough, Check list of the Lepidop- 



tera of Boreal America, No. 4648, 1917.— McDunnough, Check list of the 



Lepidoptera of Canada and the United States of America (Part 1, Macro- 



lepidoptera), No. 5138, 1938. 



Male. — Cinereous, with a brownish-ocherous tinge, often with a 

 conspicuous sprinkling of fuscous scales. Transverse lines dark, sinu- 

 ate, occasionally accentuated on the veins by dots; pale, specimens 

 with the transverse lines faint or absent. 



Alar expanse, 25-37 mm. 



Genitalia (figs. 11, 11A, 11B, 11C) : Gnathos narrow; anellus short; 

 f urea short, not compressed ; penis without cornuti. 



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



Alar expanse, 24-38 mm. 



Genitalia (fig. 26) : Ventral operculum only partially sclerotized 

 or sclerotization absent; sclerotization along ventral margin of the 

 genital opening incomplete (central portion not sclerotized) ; pos- 

 terior internal band of ductus bursae not heavily sclerotized; bursa 

 copulatrix elongate; signum ovate with margin serrate. 



Type. — In Rutgers College collection. 



Type locality. — Glenwood Springs, Colo. 



Food plant. — Quercus. 



Distribution. — United States: Arizona (June, July, Sept.), Colo- 

 rado (Aug., Sept., Oct.), New Mexico (Sept.), Utah (Aug., Sept.). 



Eighty-one specimens examined. 



Remarks. — Superficially this species closely resembles vitraria, but 

 it has the transverse posterior line more sinuate. The genitalia of 

 the two forms are distinct. The males of punctata are easily recog- 

 nized by the narrow gnathos, the short anellus, and the short stubby 

 furca, and the females by the absence of or partial sclerotization of 

 the ventral operculum, the incomplete sclerotization along ventral 

 margin of the genital opening, and the smaller, less concave signum.
