not at all dilated; side pieces of oedeagus rather strongly arched, 

 briefly excurved at tip, the latter blunt with the outer angle dis- 

 tinct and a little prominent from a certain viewpoint. 



Female: Elytra and tarsi as in the male; fifth ventral rounded 

 at apex as usual. 



Of the seven examples before me (3 (^ 's, 4 5 's) six were taken 

 in July by Dr. Fenyes and the writer at Lake Tahoe (Tahoe City 

 and Deer Park Inn) ; the seventh example, in Dr. Van Dyke's col- 

 lection bears label "Bubbs Cr. Cn., Kings River, Fresno Co., Cal. 

 Alt. 9700 feet, July 14, 1910." Since writing the above Dr. Van 

 Dyke has sent me a series of 9 9 's taken at McCloud in Siskiyou 

 Co., June 21-July 6. 



Pediliis vittatus Horn. 

 Trans. Am. Ent. Soc. 1871, p. 279. 



Length 5.5-8.8 mm. Piceous, prothorax beneath, and sometimes 

 the margin as seen from above, narrowly pale; elytra each with a 

 testaceous vitta extending from the humerus nearly to the apex, 

 and side margin posteriorly, pale, varying to entirely testaceous; 

 legs rufotestaceous with the knees piceous, varying to entirely 

 piceous except the bases of the femora. 



Antenna pale brownish testaceous, occasionally piceous in the 

 darker specimens, moderately serrate, somewhat longer than half 

 the body in the male. 



Head black, rather densely and coarsely punctate; tempora a 

 little convergent behind. 



Prothorax less strongly transverse than usual, conspicuously, 

 rather closely punctate, the punctures slightly finer than on the 

 head, frequently with a very narrow median impunctate line. 



Elytra densely, moderately coarsely punctate, 



Male: Elytra not modified at apex; front and middle tarsi 

 dilated; side pieces of oedeagus nearly straight externally, internally 

 barbed near the tip. 



Female: Elytra as in the male; tarsi not dilated. 



The vittate elytra with their apices unmodified in the male will 

 separate this species from all others in our fauna except the next 

 (lineatus), from which the tabular characters will serve to dis-
