a short distance from tiic clxtral lumicii, dark testaceous ; iiuljesceiice short, in- 

 chned, very sparse and rather inconspicuous ; head rather small, not hall as 

 wide as the prothorax, the antenn;e rather stout, nearly as long as the head 

 and prothorax', the third joint as long as the next two combined, the seventh 

 wider than the sixth, transverse, forming a hroader suj^port for the cluh, which 

 is fully as long as the stem, cylindrical, the joints transverse and rather closely 

 connected, the last oval and pointed ; joints of the club much more than twice 

 as thick as three to six ; prothorax short, about twice as wide as long, the sides 

 broadly arcuate and coarsely, feebly and irregularly crenulate throughout, more 

 convergent anteriorly, the apex slightly narrower than the base and transversely, 

 rectilinearly truncate ; base feelily and arcuately lobed in rather more than me- 

 dian half, the fovex' very large and impressed ; side margins liroadly retlexo-ex- 

 planate, less widely so anteriorly, the basal angles very cbtuse but not rounded, 

 the apical obtusely rounded and not at all advanced ; disk not concave along 

 the base, but finely impressed within the basal bead, finely, sparsely punctate, 

 the punctures gradually becoming closer and coarser toward the sides ; scutellum 

 slightly transverse, broadly angulate behind, minutely punctate; elytra much 

 elongated, about twice as long as wide and four times as long as the pnothorav, 

 just visibly wider at three-fifths than at base and thence rapidly narrt)wed to the 

 strongly rounded apex ; humeral callus decidedly pronounced and elongate, 

 gradually disappearing at some distance from the base ; punctures impressed, 

 rather sparse, moderately coarse, gradually becoming very fine posteriorly ; sterna 

 strongly, rather closely but not very coarsely, punctured, the abdomen minutely 

 and rather densely so, especially toward the sides ; tarsi slender, the lust joint 

 of the posterior as long as the last two combined. Length 3.8 mm.; width 1.6

The locality i,s reasonably certain, but the type bore no label in the 

 cabinet of the late Dr. Levette. I considered this to be the coiicolor 

 of LeConte, for some time, but the description will not serve, espe- 

 cially regarding the " narrowly margined " sides of the prothorax of 



concolor. 



Eupisenus, gen. nov. 

 This is the only genus of the tribe Tetratomiui which has been 

 discovered thus far on the Pacific coast, the others all being inhabi- 

 tants of the Atlantic districts. The body is elongate, parallel and 

 moderately convex, with the prothorax relatively narrower than in the 

 preceding genera, and the elytral humeri somewhat exposed at base. 

 The following description of the only known species will bring out 

 other characters which may prove to be generic : — 



Parallel, polished, sparsely clothed with short fine and subdecumbent pubescence, 

 black, the legs, antennae, trophi and elytra pale luteous, the latter indefinitely 

 shaded with piceous at the middle of the flanks and pn the suture toward tip ; 

 antenniv rather stout, as long as the head and prothorax, the third joint about as
