cidecUy narrower than the base, the latter broadly arcuate ; ai)ical 

 angles obtuse; disk finely and remotely punctate, not rugose lat- 

 erally except at the immediate edges. Elytra two-thirds longer 

 than wide, scarcely at all wider than the prothorax, parallel, 

 rather acutely rounded behind ; disk subexplanate externally at 

 apex, with the apical edges finely serrate ; punctures coarse, deep 

 and sparse. Abdomen thinly but rather coarsel^^ pubescent- 

 Length 3.1-3.25 mm.; width 1.2-1.3 mm. 



California (Sta. Catalina Island). I have only seen the female 

 of this species, which may be readily recognized by the dark and 

 €rect vestiture, pale legs, polished surface and coarse elytral 

 punctures. The prothorax is much larger and less transverse 

 than in lucidiis or eenescevs. 



81. T. iii^i'iiius n. 8p. — Elongate, subparallel, strongly convex and pol- 

 ished, black with a scarcely perceptible teneous lustre; legs piceous-black, the 

 tarsi paler; antenuit pale piceo-testaceous, scarcelj' darker toward tip; pnlies- 

 cence blackish, sparse, coarse and snlterect, slightly cinereous on the elytral 

 flanks toward base, long and bristling especially anteriorly and along the 

 margins. Head three-fourths as wide as the prothorax, smooth throughout, 

 convex, finely and sparsely punctate, the frontal impressions rather narrow, 

 widely separated and distinct; epistoma sliort; lal»rum acutely parabolic, 

 gradually pale toward apex; eyes large but only moderately pi'ominent; au- 

 tennse much longer than the prothorax, gradually and perceptibly incrassate to- 

 ward tip, the jjenultimate joints strongly transverse, fifth distinctly dilated. 

 Prothorax but slightly more than one-half wider than long, the sides perfectly 

 parallel and broadly arcuate at the middle, where the disk is widest, 

 straight toward the basal angles which are obtuse and not rounded and dis- 

 tinct; apical angles feebly obtuse and distinct, only slightly blunt; disk 

 finely, sparsely i)unctate, not rugose near the sides. Elijira three-fifths longer 

 than wide, distinctly wider than the prothorax, subparallel and straight at the 

 sides, evenly rounded at apex; humeri tumid, the intra-humeral impression 

 strong; punctures fine but strong and rather sparse. Abdomen somewhat 

 thinly cinereo-pubescent. Length 2.75 mm.; width 1,2 mm. 



California ? 



The male has the inner spur of the two anterior tibia; strongly 

 dilated, and the fifth ventral one-iialf longer than the fourth and 

 truncate at tip. The single specimen before me has no indication 

 of locality, but is without much doubt from tlie region suggested.
