circularly rounded behind, rather finely but strongly punctate with polished 

 interspaces, which are relatively much wider than the punctures. Abdomen 

 and legs polished, coarsely but not very densely cinereo-pubescent. Length 

 2.7 mm.; width 1.1 mm. 



Califoniia. 



The male t^'pe of this very isolated species has the fifth ventral 

 short and broadly, feebly sinnato-trnncate at apex, but without 

 further modification. Fimhriatus raa.y be known at a glance by 

 the very short angnlate and strongly- fimbriate prothorax, very 

 coarse and bristling pale setae of the elj^tra, and by the fulvous 

 pubescence. 



46. T. pi'iiiiiosiis n. sp. — Elongate, subparallel, convex, polished, black, 

 without metallic lustre; legs and antennse black, the tarsi slightly rufo-piceous ; 

 vestiture cinereous, denuded and mutilated in the types but apparently un- 

 usually short, rather dense, with the erect pale setiv short and only distinct 

 toward apex, intermingled toward the sides of the pronotum with some long 

 stiff black hairs; marginal cilia long, stiff, black and sparse throughout. Head 

 rather more than three-fourths as wide as the ])rothorax, convex, finely, sparsely 

 punctate, smooth and polished throughout, the frontal impressions small and 

 very feeble; epistoma large, areuato-truncate, strongly transverse, pale and cori- 

 aceous; labrum large, broadly rounded, blackish in color; eyes rather large 

 but not prominent, somewhat distant from the prothorax; antennte about as 

 long as the prothorax, not very stout, the outer joints moderately transverse, 

 strongly asymmetric, with the apical sensitive patches well developed, fifth 

 scarcely dilated, third and fourth feebly picesceut. Prothorax long, scarcely 

 more than one-fourth wider than long, the sides just visibly convergent and 

 very slightly arcuate, more distinctly so near the base, the basal angles obtuse 

 but not rounded, slightly prominent though blunt; apical slightly obtuse and 

 narrowly rounded; apex feebly areuato-truncate, very little narrower than the 

 base, the latter evenly and strongly arcuate throughoiit; disk minutely, rather 

 sparsely punctate, smooth, not rugose at the sides. Elytra nearly three-fourths 

 longer than wide, perceptibly wider than the prothorax, evenly rounded be- 

 hind, parallel, finely and rather closely punctate. Ahdomen clothed with 

 somewhat long coarse and cinereous pubescence. Length 3.1-4.2 nun.; width 

 1.15-1.5 mm. 



California. 



The two female types before me differ greatl}^ in size, and have 

 the pubescence not only denuded in great part but more or less 

 broken, so that it is not possible to state its true development 

 with much precision. The species is remarkably distinct, as may 

 be judged by the description, and is one of those forms which it 

 is difficult to assign to either Byturosomus or Emmenotarsus of 

 Motschulsky, proving that those groups are not tenable as genera.
