26 JOUENAL OF ENTOMOLOGY AND ZOOLOGY 



of oedeagus nearly straight, a little divergent apically, finely barbed 

 interiorly near the tip; middle piece very slender, gradually finely 

 acuminate with a small dilated or bulbiform tip which is inferiorly 

 hooked when viewed laterally. 



Female: Elytra unmodified at apex; the fifth ventral deflexed 

 but less strongly so than in the male; tarsi not dilated. 



This fine distinct species may be at once recognized by the unusu- 

 ally dense pubescence, combined with the deeply impresso-excavate 

 elytral tips and strongly deflexed fifth ventral segment in the male. 

 One other species only — flcxivcntris — has the same type of impres- 

 sion of the elytral apices, though rather less deep and scarcely re- 

 cessed, and also has the strongly deflexed fifth ventral, but it differs 

 otherwise in its smaller size different color, coarse elytral punctua- 

 tion and normally sparse pubescence. 



Cavatiis inhabits California from the vicinity of San Francisco 

 to the northern boundary. The following localities are represented 

 in the 15 examples before me, the majority of which were col- 

 lected by Dr. Van Dyke; others by Nunenmacher and Blaisdell. 



Alameda Co. (type) ; Contra Costa Co. (Redwood Canon, 

 May 28); Marin Co. (Fairfax, June 13; Muir Woods, May 

 14-17) ; Sonoma Co. (Eldredge, April 14; Sobre Vista, April 30) ; 

 Trinity Co. (Carrville, June 6-27); Humboldt Co., May 15; 

 Siskiyou Co., June 2. 



Pedilus flexiventris n. sp. 



Length 3.8-6 mm. Black, prothorax reddish yellow; elytral apex 

 yellow in the male. 



Antenna moderately serrate, longer than half the body in the 

 male, about half the length of the body in the female. 



Head and prothorax minutely remotely punctate, the hind angles 

 of the former scarcely more closely so. 



Elytra densely and coarsely punctate. 



Male: Apices of elytra abruptly compressed, the compressed 

 area entirely yellow, its anterior walls vertical or even slightly in- 

 flexed and extending obliquely outward and forward from the 

 suture; fifth ventral segment strongly deflexed; front and middle 

 tarsi a little dilated; side pieces of oedeagus nearly as in cavatus, 

 the middle piece similar except that it is not dilated at tip.
