20 WILLIAM G. DIETZ, M. D. 



S. trans verMestrigel lit n. s. — Grayish to brownish ochreous. Palpi 

 dusted with fuscous. Head more brownish, lustreless. Thorax overlaid with 

 purple brownish, patagia darker in front. Forewings narrow, elongate, pointed, 

 more grayish ochreous, sprinkled with brown scales; a row of rather large spots 

 along the entire costal margin, less sharply defined and more irregular in the 

 basal half, more conspicuous and distinct iu apical half, these spots extend as 

 transverse lines, more or less interrupted across the wing and reach the dorsal 

 margin, where, however, they become less distinct, these lines are more evident 

 in the apical part of wing, the interspaces between them being more densely 

 sprinkled with dark scales, the latter being rather scant in the subplical space. 

 Cilia densely sprinkled with purple-brown scales, the dark color being interrup- 

 ted by several pale lines. Hindwings elongate, pointed, grayish fuscous, cilia 

 concolorous. Abdomen and legs ochreous fuscous, tarsi spotted with dark brown. 



Exp. 12.0-15.0 mm. 



Hab. — Calif. (Pasadena) ; a number of specimens in my collection. 

 Wings more elongate than in either of the two preceding species, 

 and darker in coloration than inamcenella. 



APRETA gen. n. 



Type paradoxella. 



Labial palpi short and very robust, porrect, first joint truncate, 

 with a few setae beneath, the second scarcely longer than wide ante 

 riorly, obliquely truncate antero-inferiorly, the truncature clothed 

 with short, bristly hair, the third joint half as long on its upper sur- 

 face than the preceding one, oval, flattened, depressed, with short 

 stiff hairs projecting from its anterior margin. Head, viewed from 

 above, very short, transverse, smooth scaled, posterior margin with 

 a whirl of stiff hair each side; front receding beneath. Eyes small, 

 hemispherical. Antennae as long as the forewing, very slender, first 

 joint strongly, the second slightly incrassate. Forewings elongate, 

 pointed; costa slightly curved from the base; 12 veins, vein 2 from 

 posterior angle of cell, 7 and 8 stemmed, \ b furcate. Hindwings 

 elongate-ovate, pointed, 8 veins, vein 2 from posterior angle of cell, 

 parting vein of latter bifurcate, veins 5 and 6 out of one point, 

 \ b strongly furcate ; frenum absent. Legs stout, tarsal joints with a 

 verticel of spinules of unequal length at their apical extremity, 

 most strongly developed on the posterior, less so on the middle and 

 scarcely perceptible on the anterior feet. 



The genus thus defined presents characters peculiarly unique and 

 striking, and could not be confounded with any other of the group. 

 In habitus and tarsal structure it agrees well with the following, but 

 differs in palpal structure and venation. 



But one species known to me.
