Remarhs. — In this large series are two specimens (approximately 

 1 o/o) with short broad wings which otherwise are quite normal and 

 apparently functional. These two are not crippled in any sense, and 

 were reared under the same conditions as were the rest, which suggests 

 that this short-winged form may be the result of a Mendelian factor 

 such as has been demonstrated in experiments with DrosophUa. 



I mention these short- winged forms merely to show that if they were 

 collected in nature they would undoubtedly be described as a distinct 

 species (distinct from that to which they actually belong). 



Since this species was described I have been able to rear a series of 

 over 200 moths from various localities in the states of Idaho and 

 Washington. The Utah specimens are somewhat smaller than those 

 from Idaho and Washington and show slight variations in the gen- 

 italia but unquestionably belong here.

A very distinct, medium-sized, grayish species close to leptotaeniae. 



Labial palpus with second segment white strongly irrorated with 

 blackish fuscous; third segment blackish fuscous sparsely irrorated 

 with white; apex white. Antenna with basal segment blackish 

 fuscous with a whitish-ochreous patch beneath at apex; remainder 

 of antenna brown above, whitish ochreous beneath, narrowly an- 

 nulated with blackish fuscous. Head light brownish fuscous, the 

 tips of the scales whitish. Thorax and ground color of fore 

 wing brownish ochreous mixed with white scales. Bases of tegula 

 and fore wing blackish fuscous; costa of fore wing fuscous mixed
