This siK-cics is very closely allied to the following, and ii is doubtful whether they 

 should be retained as distinct. The only differences being in the rather rounder form 

 and deeper frontal impression of this species. Should these two prove to lie identical, its 

 distribution woidd prove nearly as extended in tin' Northern regions as janus in the 

 Southern. Oregonese is always brownish in color, never black; the antenna' are j. 

 tic presternum horizontal, tip acute and prominent. 



Length .20-.26 inch. 



Distributed from Oregon to Fori Tejon, Cal.
