CLEAR-WING MOTHS OF FAMILY AEGERIIDAE 83 



marked with white before the tips in both sexes; in proxima only the 

 females are thus marked. 



C. albicornis was described by Hy. Edwards from a female, not a male 

 as he states, labeled Nevada (Morrison) . That is a vague designation, but 

 most likely applies to the mountainous western part of the State. Avail- 

 able records include: San Juan Mountains. Colo., 1 male (Oslar) ; Coolin, 

 Priest Lake, Idaho, July 24, 1927, 1 female; Snoqualmie Pass, Wash. 

 (V. Argo), July 25, 1925, 1 male; Mount Rainier, White River Camp.. 

 Wash. (James Wilcox), August 7, 1935, 5 males, 1 female; Plumas 

 County, CaHf. (F. M. Jones), July 20, 1918, 1 female; Meadow, Plumas 

 County, Calif., 4,000 feet (Van Dyke), June 21, 1924; Los Angeles 

 County, Calif. (Coquillett), 1 female reared in March, 1 female reared in 

 April, 1 male reared in October. 



This species is well distributed from the Pacific coast to the Rocky 

 Mountains and northward into British Columbia. At Madeline, Lassen 

 County, Calif., a heavy infestation was evidenced by masses of brown 

 pellets and pupal exuviae from larval burrows in exposed roots of low- 

 growing willows, too late in the season to obtain adults. Otherwise mod- 

 erate swellings on willow canes and branches indicate attacks. At River- 

 side, Calif., C. M. Dammers reared examples found boring in the bark of 

 fairly large tree willows. As in the East, the species in the West also often 

 enters abnormal growth or wounds caused by coleopterous larvae.
