pieces of oedeagus nearly straight, barbed internally near the tip. 



Female: Apex of elytra less widely margined, tarsi not dilated. 



The more widely reflexo-explanate apical margin of the elytra 

 in the male without other modification (the pale tips in some ex- 

 amples not being a constant character) distinguishes this species 

 from all others in our fauna. The females may, with care, be dis- 

 tinguished from other species occurring in the same region by the 

 relatively densely punctate head, in which respect it is only sur- 

 passed by vittatus and lineatus. 



The type is one of a series of specimens taken by Nunenmacher 

 in Josephine Co., Oregon, June 8-11. Other examples were found 

 by Nunenmacher on the same collecting trip in Siskiyou Co., Cali- 

 fornia, May 31. I have also seen a single $ from Cole, Siskiyou 

 Co., California (Fenyes) ; two examples from "Or" and one each 

 from Cooks, Wash., and White Salmon, Wash., in Prof. O. B. 

 Johnson's collection, and have received a $ from Corvallis, Ore- 

 gon, June 6 (Moznette). 



Pedilus cavatus n. sp. 



Length S.6-1 S mm. Head and body beneath black, prothorax 

 rufotestaceous, elytra flavotestaceous, the apex blackish in both 

 sexes; legs variable from entirely pale except the knees, to black or 

 piceous with the tarsi and apical parts of the tibiae paler. 



Antenna entirely black, more than half the length of the body 

 in the male, the apices of the joints strongly oblique; less strongly 

 serrate and not longer than half the body in the female. 



Head minutely sparsely punctate, the hind angles and especially 

 the sides beneath more closely and coarsely so. 



Prothorax very finely sparsely punctate. 



Elytra densely, rather finely punctate and with the pubescence 

 longer and denser than usual, the surface lustre in consequence 

 somewhat dull. 



Male: Apex of each elytron with an abrupt deep oblique termi- 

 nal impression, which is somewhat recessed anteriorly, the im- 

 pressed area — except the extreme margins — black, polished and 

 nearly impunctate; fifth ventral segment almost perpendicularly 

 arcuately deflexed, its apex truncate and just perceptibly arcuato- 

 emarginate; front and middle tarsi distinctly dilated; side pieces
