612. Sosipatra thurberiae (Dyar), new combination 

 FiGUEES 619, 1107 



Eurythmia thurberiae Dyar, Ins. Insc. Menstr., vol. 5, p. 46, 

 1917.— McDunnougli, Check list No. 6393, 1939. 



Forewing bluish gray more or less dusted with black, 

 in some specimens the entire area between the trans- 

 verse lines suffused with black, a fine whitish dusting 

 usually sets off the entire basal area; antemedial line 

 weU out towards middle of wing, narrow and nearly 

 vertical, narrowly bordered outwardly by some accentu- 

 ation of the black dusting; subterminal line parallel to 

 termen, slightly angled inwardly at vein 6 and lower 

 fold; discal dots more or less distinct (at least the lower 

 one) and from them a broadening wedge of pale scaling, 

 extending to costa; terminal dots obscure, more or less 

 confluent. Hind wing white to pale smoky fuscous; 

 the veins more or less darkened and a narrow dark line 

 along termen. Alar expanse, 11-19 mm. 



Male genitaUa similar to those of anthophUa but 

 easily distinguished by the shapes of transtUla and 

 apical process of gnathos; terminal margin of vinculum 

 evenly rounded. Female genitalia with very slender 

 signum; 



Type locality: Bowie, Ariz, (type inUSNM). 



Food plants: Cercis occidentalis (larvae in pods), 

 Quercus (larvae in "oak-apple" galls on leaves), Thur- 

 heria (larvae in seed pods) . 



Distribution: Arizona, Bowie (Jime); California, 

 Applegate (July, Aug.), Buelton (Jxily), Calpella (July), 

 Gasquet (July), Hopeland (July), San Felipe Wash 

 (San Diego County, June), Thi'ee Rivers (Apr.); 

 Oregon, Dundee (Aug.), Eugene (July), Woodburn 

 (Aug.). 



Genus Sosipatra, Species 613-615: S. nonparilella 

 to S. divergens 



[Harpe with apex of costa and cucullus upturned; eighth ab- 

 dominal segment of male simple.] 



613. Sosipatra nonparilella (Dyar), new combination 



Figure 621 



Ephestia nonparilella Dyar, Proc. Ent. Soc. Washington, vol. 6, 

 p. 113, 1904.— McDunnough, Check list No. 6404, 1939. 



Forewing white dusted with black, giving the wing a 

 pale ashy gray ground color; discal spots and borders of 

 transverse lines black and strongly contrasted; ante- 

 medial line indicated chiefly by its outer border, far out 

 on wing (about middle), just below costa angled inward 

 and running parallel with subterminal line; the latter 

 white and straight except for a very shght notch at 

 lower fold, parallel with and rather close to termen; 

 discal dots confluent, forming a black streak along 

 discoceUular vein. Hind wing white, translucent; its 

 terminal margin but slightly darkened. Alar expanse, 

 18 mm. 



Male genitalia distinguished by shape of apical 

 process of gnathos (fig. 621a). 



Type locality: Santa Rita Mts., Ariz. (Jime; type 

 in USNM). 



Food plant: Unknown. 



KJaown only from the male type. Dyar's original 

 description is in error in one particular. He states that 

 veins 3 and 5 of hind wing are "separate, but approxi- 

 mate at base." They are distinctly connate. 



614. Sosipatra majorella (Dyar), new combination 



Figures 620, 1108 



Ephestia majorella Dyar, Ins. Insc. Menstr., vol. 10, p. 173, 1922. 



Forewing similar to that of micaceella but with less 

 contrast between the costal and inner areas, and the 

 black borders of the transverse lines broader, more 

 complete (not broken into dashes) ; ground color dark 

 gray-brown with some lighter rust-brown scaling in the 

 folds; antemedial line slightly angled just below costa; 

 the black inner border of subterminal line angled out- 

 wardly at middle; discal spots confluent, black. Hind 

 wing of male light brown, of female, whitish fuscous; 

 the veins and terminal margin darker. Alar expanse, 

 20 mm. 



Male genitalia similar to those of nonparilella except 

 for a somewhat broader transtiUa, more slender aedea- 

 gus and differently shaped apical projection of gnathos. 

 Female genitalia with signum; bursa otherwise smooth. 



Type locality: Guadalajara, Mexico (type in 

 USNM). 



Food plant: Unknown. 



In addition to the male type there is in the National 

 Museum from Mexico City (Aug.) a female which 

 Schaus or Dyar had associated with micaceella. Its 

 maculation is a much better match for that of majorella, 

 with which I associate it. The two species differ radi- 

 cally in male genitalia but are similar in color and pattern 

 and easily confused. On the other hand, while they 

 differ markedly in color, the types of majorella and nan- 

 parilella exhibit only minor structural differences. 



615. Sosipatra divergens (Dyar) 

 Figure 1109 



Ephestia divergens Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 345, 

 1914. 



Forewing dark gray-brown; antemedial line vertical, 

 at middle of wing, bordered outwardly by black; sub- 

 terminal line oblique, slightly curved at fold, margined 

 within by a thin black line; discal spots confluent, form- 

 ing a blackish line along discoceUular vein. Hind wing 

 pale fuscous, veins and terminal margin very slightly 

 darker. Alar expanse, 16 mm. 



Female genitalia without signum. Male unknown. 



Type locality: Taboga Isl., Panamd (type in 

 USNM). 



Food plant: Unknown. 



KJaown only from the unique female type.
