Psyche 
[March 
Holotype number 15949 in the Museum of Comparative 
Zoologjr, collected by Professor C. T. Brues in “Hot Spring no. 
15; Opal Mine 25 mi. So. Denio, Ore.” Paratypes: 61 with the 
same data as the holotype. Paratypes to be deposited in the 
Museum of Comparative Zoology, the United States National 
Museum, the Canadian National Collection, the California Acad- 
emy of Sciences, the collection of Mr. H. C. Fall, and that of the 
writer. 
This species is allied by the pronotal sculpture and the char- 
acter of the ventral pubescence to Helmis pusilla , foveata, and 
similis, but it may be easily distinguished by its much narrower 
form and the coarsely punctate, inconspicuously costate elytra. 
Occasionally the punctures of the elytra are filled up or concealed 
by a superficial layer of dirt, but the remaining characters are 
sufficient to make the species readily recognizable. Professor 
Brues found two specimens of H. similis in the same locality.
