Face, head and thorax light ochreous fuscous, with single blackish scales inter- 

 spersed ; shoulders darker, purplish. Forewings whitish fuscous with a violet or sil- 

 very sheen and sprinkled with light brown, dark fuscous and black scales. 



The brown scaling is confined to the costal and apical half of the wing ; the 

 dark scales are arranged in poorly defined short longitudinal streaks especially towards 

 the costal edge and towards apex, which produce a veined effect ; fold and area 

 around tornus nearly free from dark scales. Cilia whitish ochreous. Hind wings 

 light silvery fuscous ; cilia ochreous fuscous. Abdomen silvery fuscous, sprinkled with 

 black. Legs whitish fuscous. Alar expanse, 22 ram. 



Habitat: Williams, Arizona (Schwarz and Barber). U. S. Na- 

 tional Museum, type No. 6755. 



Cerostoma striatella, sp. nov. 



Antenna3 white towards the apex with dark brown annulations. Labial palpi, 

 especially second joint, unusually short for the genus ; brush very short ; terminal joint 

 thickened with rough scales ; white with a few dark scales on third joint. Head and 

 thorax white, a narrow black streak on the shoulders. Forewings dull chalky white 

 with narrow more or less interrupted purplish-black longitudinal streaks, best defined 

 in apical half of the wing and radiating somewhat from the end of the cell towards 

 costal and dorsal edge. Dorsal edge below the fold only sparsely sprinkled with dark 

 scales. Cilia white, tipped with black. Hindwings whitish towards the edges, light 

 ochreous fuscous ; cilia white ; abdomen white, mottled above with dark fuscous ; 

 ovipositor protruded, horny, stout. Legs whitish, slightly mottled with fuscous. 

 Alar expanse, 23 mm. 



Habitat: Los Angeles, California (Koebele). U. S. National 

 Museum, type No. 6757. 



Abebaea Hilbner. 



Forevving shorter and broader than in the foregoing genus, less 

 than three and a half times longer than broad; smooth; 12 veins, 7 

 and 8 separate or stalked, 7 to termen, 2 and 3 separate. Tuft on 

 second joint of labial palpi well developed, compressed, pointed, 

 longer than terminal joint. Wallengren, Heinemann and other 

 European writers have stated that the ocelli are absent in this group ; 

 this is at least not always correct, and even the European species have 

 ocelli. Thus one of Wallengren' s distinguishing characters for this 

 genus (his genus Credemnon) is spoiled and I admit that I should 

 hardly have given this group generic value if it had not been done by 

 others before me. However the long-pointed brush on second joint 

 of labial palpi, the broader wings and a certain undefinable general 

 habitus prove that it is a natural division at least of the foregoing 

 genus and afford sufficient help to distinguish it from the other natural 

 division to which the name Cerostoma is restricted.
