480 Goleopterological Notices, VI. 



base broadly arcuate; marginal fringe very short; disk rather finely, sparsely 

 punctate, coarsely scabrous toward the sides. Elytra barely three-fifths longer 

 than wide and just visibly wider than the prothorax, parallel and straight at 

 the sides, the apex subcircularly rounded; sutural angles rounded; humeri 

 tumid; punctures rather fine and close-set, subrugose, the interspaces polished. 

 Abdomen coarsely piibescent, minutely but not very densely jjunctulate, the 

 legs long. Length 3.8 mm.; width 1.5 mm.

This ven' distinct species is represented by a single male, hav- 

 ing feeble sexual modifications at the abdominal vertex, the fifth 

 segment being truncate and apparently very feebly- sinuate to- 

 ward the middle, with the surface unmodified; the genital seg- 

 ment is impressed along the middle as usual. 



10. T. traiisversus n. sp. — Oblong, moderately convex, shining, black, 

 the upper surface with very feeble subseneous lustre; legs black, the tibiae and 

 tarsi piceous; antenna:- piceous, the basal joint black; pubescence sparse but 

 rather long, somewhat coarse, cinereous and distinct ; marginal fringe short on 

 the prothorax, much longer on the elytra. Head fully three-fourths as -vWde 

 as the prothorax, finely, sparsely but subasperately punctate, rugose toward 

 base, the frontal impressions strong and separated T)y a sensibly elevated im- 

 punctate area; epistoma pale and coriaceous; labrum transversely arcuate at 

 apex; eyes rather large and prominent; antenna not very stout, one-half lon- 

 ger than the prothorax, the fifth joint but feebly dilated, tenth strongly trans- 

 verse. Prothorax very short and transverse, nearly twice as wide as long, 

 the sides parallel, e\enly and somewhat feebly arcuate from l)ase to apex, the 

 latter evenly and feebly arcuato-truncate throughout the width, the base 

 scarcely visibly more arcuate; basal and apical angles almost equal, 

 slightly obtuse and rounded but distinct; disk rather finely, sparsely 

 perforato-punctate, the edges of the puuctures elevated or burred, broadly 

 scabrous toward the sides. Elytra three-fiifths longer than wide, about equal 

 in width to the prothorax, parallel and straight at the sides; apex broadly 

 rounded; humeri tumid; flanks impressed toward base; punctures rather fine 

 and moderately close-set, subrugose, the interspaces polished. Abdomen 

 somewhat finely and thinly pubescent, the punctures very fine and feeble. 

 Length 3.25 mm.; width 1.35 mm. 



California (San Francisco). 



The male has the fifth ventral unmodified on the disk, the apex 

 truncate and apparentl}'' ver} slightly' sinuate toward the middle, 

 the genital segment broadl}' impressed, fineh* canaliculate along 

 the middle and broadl}' emarginate at apex. This species is allied 

 to several of the cyHnd7-icus group, but is distinguishable at once 

 from any of them by the verj' short prothorax, and, from fra-
