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 nun.

The male type of this very isolated species has the fifth ventral 

 short and broadly, feeLly sinuato-truncate at apex, but without 

 further modification. Fimhriatus may be known at a glance by 

 the very short angulate and strongly- fimbriate prothorax, very 

 coarse and bristling pale setfe of the elytra, and by the fulvous 

 pubescence. 



46. T. priiiiiosiis n. sp. — Elongate, subparallel, convex, jiolished, black, 

 without metallic lustre; legs and antenna- 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 set;v 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 prothorax, convex, finely, sparsely 

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

 very feel )le; epistoma large, arcuato-truncate, strongly trans\erse, pale and cori- 

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

 but not prominent, somewhat distant from the piothorax; antennje 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 picescent. Prothorax long, scarcely 

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

 very slightly arcuate, more distinctly so near the base, the l)asal angles obtuse 

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

 nan-f)wly rounded; apex feebly arcuato-truncate, very little narrower than the 

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

 sparsely punctate, smooth, not rugose at the sides. Elytra ut'ar\y 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 15.1-4.2 mm.; width 

 1.1.5-1. .5 mm.

The two female types before me differ greatly 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 assigu to either Byturosomus or Emmenotarsus of 

 Motschulsk3^ proving that tiiose groups are not tenable as genera.
