club small, narrowly oval, pointed and with its basal joint consti- 

 tuting nearly one-half of the mass. 



The prothorax is subtubulate at apex, the anterior coxse large, 

 prominent and separated by not quite their own width, the pro- 

 sternnm in the male having a large, oval, extremely deep median 

 excavation and two ante-coxal processes of great length, extending 

 far in advance of the head, and upwardly everted at apex. The scu- 

 tellum is large, slightly trapezoidal, smooth, polished, flat, entirely 

 unimpressed and feebly, sparsely punctulate toward base only.^

Black, polished, the pronotum with two broad lateral vittiB of 

 orange-red scales, the vitt^ abruptly flexed beneath anteriorly, ex- 

 tending to the prosternal excavation. Elytra each with a single 

 broad vitta of the same color, occupying the entire width of inter- 

 vals three and four, and extending from the base to apical fourth. 

 Met-episterna and sides of the last three ventral segments similarly 

 clothed. Length 5.8 mm.; width 3.1 mm. 



The male referred to above is labeled " Texas," and, if this is 

 correct, indicates a distribution similar to that of Hemirhipus fas- 

 cicularis. 



PYCHYBARIS. 



LeConte— Proc. Am. Phil. Soc, XV, p. 302. 



The original type is still the only known species assignable to 

 this distinct and somewhat isolated genus. The body is short and 

 very robust, feebly setose, polished and, although normally centri- 

 niform in pygidial structure, possesses many of the characteristics 

 of Onychobaris, as remarked by its author. 



The beak is rather long, strongh' arcuate, with the punctures not 

 very dense and arranged in subimpressed series, more confused at 

 the sides toward base, the mandibles not in the least decussate when 

 closed, but coming together on the axial line as in Centrinus. The 

 antennae are inserted far behind the middle of the beak, with the 

 scrobes moderately oblique, attaining the eyes, the scape short, the 

 funicle gradually thick toward apex, almost continuous in outline 



1 Since this was written I have received specimens of the true distinctus, 

 taken near Rio de Janeiro, and find that they are identical with the Texan 

 representative.
