OF WASHINGTON. 113 



The larva was black, five-eighths of an inch long, the head yellow, 

 retractile; thinly covered with short white hairs. The leaf was 

 folded lengthwise and upwards, the edges tightly fastened to 

 gether, giving the fold a very sharp edge, the entire leaf looking 

 like a pod. Within the fold there is a web which holds the ex 

 crement suspended." (Chambliss.)

Ephestia nonparilella, n. sp. 



Head round, eyes large; labial palpi upturned weakly, second and third 

 joints nearly equal, not reaching vertex ; maxillary palpi filiform; tongue 

 moderate; <$ antennas simple. Fore wing with 9 veins, all free; hind 

 wing with 6 veins, 5 and 8 wanting, 3 and 4 separate, but approximate at 

 base. 



Fore wing long and narrow; pale gray, irrorate with black scales ; lines 

 black, distinct, contrasted, parallel, the inner at the middle of the wing, 

 the outer at the outer fourth. Both are slightly oblique, parallel to the 

 outer margin^ straight, the inner edged within with white, the outer edged 

 without and more distinctly so. Discal spots joined, black, touching a 

 black cloud on costa. Hind wings whitish, subpellucid. Expanse 18 mm. 



One cT? Santa Rita Mountains, Arizona, June 7 (E. A. Schwarz). 

 Type. No. 7929, U. S. National Museum. 



Psorosina, n. gen. 



Fore wings with n veins, 4 and 5 separate. Sand 9 stalked; hind wings 

 with 7 veins, 2 at the angle of the cell, 3 and 4 stalked. $ antennae bent 

 above base with a tuft of scales in the bend ; tongue moderate ; labial 

 palpi erect, recurved to vertex; maxillary palpi small, filiform. 



Under this I place hammondi Riley and the following new 

 species. Hulst puts hammondi in Canarsia* of which he says: 

 u Close to Psorosa Zell., differing principally in the stemming 

 of veins 4 and 5." But Psorosa has long wings with a scale 

 ridge, while the palpi are long and porrect (European dahliella 

 Tr.). In ulmiarrosorella Clem., veins 4 and 5 of fore wings are 

 stalked and Canarsia must be restricted to this, including per^ 

 haps graciella Hulst, which I do not know. 



Psorosina angulella, n. sp. 



Shining dark brownish gray ; inner line broad, whitish, obscurely gemi 

 nate, rather diffuse, the costal half oblique, the inner half straight. Dis 

 cal dots black, joined in an oblique white cloud; outer line near margin, 

 faint, pale, straight. Hind wing pale fuscous. Expanse 14 mm. 



One ji, Iowa (C. P. Gillette). Very close to hammondi ', 

 but the inner line is strongly angled. It may prove a variety of 

 hammondi.
