4647, 1917. — McDunnough, Check list of the Lepidoptera of Canada and 

 the United States of America (Part 1, Macrolepidoptera), No. 5136, 1938. 

 Therina vitraria (Grote) Hulst, U. S. Nat. Mus. Bull. 52, p. 334, 1903. 



Male. — Pale ocherous, with a light sprinkling of fuscous scales on 

 the wings. Transverse lines on fore wing evenly curved, often weak 

 or obsolete between the veins, usually more strongly accentuated on 

 the veins. Transverse line of hind wing often continuous. 



Alar expanse, 30-35 mm. 



Genitalia similar to those of typical athasaria. 



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



Alar expanse, 27-35 mm. 



Genitalia similar to those of typical athasaria. 



7^.— U.S.N.M. No. 34295. 



Type locality. — New Mexico. 



Food plant. — Unknown (probably Quercus). 



Distribution. — United States: Colorado (June, July), New Mexico 

 (July, Aug.). 



Nineteen specimens examined. 



Remarks. — Specimens of vitraria resemble typical athasaria in 

 habitus but with the average size smaller, irrorations weaker, general 

 color somewhat more ocherous, and the transverse lines of the fore 

 wing more obscure, usually indicated only by dots on the veins. No 

 constant structural differences were observed. The name should be 

 applied to the rather small, pale ocherous southwestern race of 

 athasaria. 



12. LAMBDINA ATHASARIA JACULARIA (Barnes and McDunnough) 



EUopia jacularia Barnes and McDunnough, Contr. Nat. Hist. Lepid. Norl'n 

 America, vol. 3, No. 4, p. 254, 1917. — McDunnough, Check list of the Lepidop- 

 tera of Canada and the United States of America (Part 1, Macrolepidoptera), 

 No. 5137, 1938. 



Male. — Resembles vitraria but is larger and a trifle darker with the 

 sprinkling of fuscous scales heavier; transverse lines of the fore wing 

 somewhat stronger (as in typical athasaria). 



Alar expanse, 35-40 mm. 



Genitalia similar to those of vitraria. 



Female. — Unknown. 



Type.— U.S.N.M. No. 55724. 



Type locality. — Jemez Springs, N. Mex. 



Food plants. — Unknown (probably Quercus). 



Distribution. — United States: New Mexico (Apr., May). 



Seven specimens examined. 



Remarks. — Barnes and McDunnough noted the close relationship 

 of jacularia and vitraria but stated that the genitalia differed, the
