The valves of the $ genitalia appear more lobate and lack the 

 strong ridge along the dorsal margins which is present in chandleri. 



The present species is probably local. O. chandleri has a wide 

 distribution and is represented in the Barnes Collection from Utah, 

 Colorado, Wyoming, California and Alberta. 



Type locality: Trout Creek, Ibapah Mts., Utah (Tom Spalding). 



Number and sexes of types: Holotype S, 21-IX-22; Allotype 2, ll-IX-22. 



Oncocnemis utaiiensis sp. nov. 



Xextranea B. & McD. (nee Sm.). 



1912, B. & McD, Contrib. N. H. Lep. N. A, I, (4), 10, pi. Ill, f. 14, 

 Oncocnemis. 



Very closely allied to extranea in superficial appearance ; but much paler 

 in color, the primaries lacking strong brownish tints ; an s. t. line often faintly 

 indicated by white dots; somewhat smaller in size. The above mentioned 

 plate, which is good, will serve to show the maculation. 



Expanse: 30-31 mm. 



The valve of the male genitalia is much narrower and less blunt caudally; 

 and altho there appears to be considerable variation in both species, this char- 

 acter seems to hold. In addition, there is some difference in the corona. 



Besides the types, there is a single specimen in the Barnes Col- 

 lection from Stockton, Utah, (ex. Coll. J. Doll). 



Type locality: Eureka, Utah (Tom Spalding). 



Number and sexes of types: Holotype $, 19-VIII-ll, (the specimen fig- 

 ured, as above listed) ; Allotype ?, 22-VIII-ll; 25 5, 13 $, Paratypes, various 

 August and September dates. 



Oncocnemis sectilis Sm.

 ignot., fLeucocnemis. 



This species is closely related to griseicollis and may tentatively 

 be placed in Oncocnemis.
