flattened or feebly grooved on the inner side; fourth ventral seg- 

 ment produced in a broad lobe with bisinuately truncate apex; fifth 

 ventral transversely tumid at middle, the apex broadly sinuately 

 emarginate. Side pieces of oedeagus broadly arcuate, not hooked 

 or barbed on the inner margin, the tips rounded; central piece 

 gradually pointed, the tip narrowly rounded. 



Female: Elytra pruinose; tarsi not dilated; hind tibis not dis- 

 tinctly arcuate or flattened; fifth ventral broadly rounded and de- 

 flexed at apex. 



This is one of the most distinct of the West Coast species and 

 with the exception of the next is quite unique in its tibial and ab- 

 dominal secondary sexual characters. It is not rare in the higher 

 parts of the Middle Sierras of California, and has been found just 

 across the line in Western Nevada, and also in Northern Califor- 

 nia, where a race with black thorax occurs in Siskiyou, Shasta and 

 Trinity Counties. In Dr. Fenyes' collection there is a 5 example, 

 also with black thorax, from the Rocky Mountains of Colorado. 

 Specific localities in the material before me are as follows: 



California: Tulare Co. (Mineral King 8000 feet and Mon- 

 arch Lake 10500 feet, August 3rd and 4th, G. R. Pilate; Gray 

 Meadow, July 3 — Hopping): Fresno Co. (Paradise Valley, 

 7000 feet, July 16 — Van Dyke; South Fork, Kings River Canyon,

 August 3 — Hopping. 



Pedilus infectus n. sp. 

 Lengtli 5^-5 34 mm. Very close indeed to abuonuis, but of 

 smaller size, the antennae somewhat less strongly serrate, the 

 punctuation relatively a litde coarser, the front and middle tarsi 

 ( <? ) not appreciably dilated, the hind tibia? ( $ ) similarly but more 

 feebly modified, the lobe of the 4th ventral segment broadly sinu-
