New Oregon Trichoptera.

(Plates III and IV.) 
In preparing a thesis on the biology of certain Trichoptera, 
completed June, 1911, I sent a number of specimens to Dr. C. 
Betten, of Lake Forest, Illinois, to be identified. 
Six of the species submitted to Dr. Betten turned out to be 
new or probably new. One represented a new genus. It 
has been a great disappointment, that of four of these new 
species, there was not enough material to describe, in some 
cases only one imperfect specimen being in the collection. This 
was the case with the Psychomyid which represents the new 
genus. This was collected by myself, in October, 1908, at 
Crystal Lake, with five others of different species. 
The list of new Trichoptera is as follows: 
Limnophilidae. Grammataulius bettenti, n. sp. 
Sericostomatidae. Atomyia, n. sp. 
Leptoceridae. Mystacides alafimbriata, n. sp. 
Psychomyidae. n. g. n. sp. 
Rhyacophilidae. Glossosoma,n. sp. Glossosoma, probably 
new. 
The collection contained enough specimens of two of these 
species so that descriptions could be made. The first one, a 
Grammataulius, I have given the name of bettcnii in recog- 
nition of the kind assistance given me in the determination 
of specimens by Dr. Cornelius Betten. The second, a Lep- 
tocerid, has been given the descriptive name alafimbriata be- 
cause of the long, soft black fringe upon the outer and inner 
margins of the hind wings.
