The subjoined remarks give but little aid in identification and 

 need not be quoted. 



1. T. compactus u. sp. — Oljlong, rather stout, strongly convex, pol- 

 ished, piceous-black, the elytra rufo-castaneous ; under surface, legs and an- 

 tennae dark rufous throughout; pubescence coarse, decumbent, moderately 

 short and dense, pale ochreo-cinereous in color, the marginal fringe of the pro- 

 thorax and elytra moderate in length. Head slightly more than one-half as 

 wide as the prothorax, flat, broadly impressed anteriorly, finely, sparsely punc- 

 tate, the interspaces smooth; epistoma abruptly depressed, pale, coriaceous and 

 impunctate; lal)rum short, broadly arcuate at apex, the disk finely and re- 

 motely but distinctly punctate, the punctures bearing short erect setse ; eyes 

 rather large but not prominent; antennaj somewhat slender, subequal in length 

 to the prothorax, the fifth and seventh joints larger than the sixth and eighth, 

 penultimate wider than long. Prothorax large, broadly campanulate, about 

 one-half wider than long, the sides broadly rounded and convergent toward 

 apex, outwai'dly sinuate toward base, the basal angles acute and strongly 

 everted; apex feebly sinuato-truncate, the angles broadly rounded; disk 

 minutely, sparsely punctate throughout, the interspaces smooth and polished. 

 Elytra only slightly wider than the prothorax, scarcely more than one-half 

 longer than wide, two and one-half times as long as the prothorax, parallel and 

 straight at the sides, broadly, obtusely rounded at apex, the vertical flanks 

 longitudinallj' impressed toward base; humeri obtusely prominent; disk finely, 

 evenly and somewhat closely punctate. Abdomen finely, rather closely punc- 

 tate, the interspaces not reticulate. Length 3.4 mm. ; width 1.5 mm. 



Southern California. 



The single t^'pe of this somewhat aberrant species is a female ; 

 it may be I'eadih' identified b}' the campanulate prothorax, with 

 acute and everted basal and rounded apical angles. 



2. T. l>revis n. sp. — Short and very broad, moderately convex, shining, 

 black throughout, the legs rufo-piceous, the antenna? throughout dark piceous- 

 brown ; pubescence moderately long and dense, pale luteo-cinereous, the hairs 

 along the lateral edges rather long, erect and bristling. Head but slightly 

 more than one-half as wide as the prothorax, finely, remotely punctate, the 

 upper surface perfectly flat throughout, without trace of subapical impression 

 but with a broad and feeble swelling at the middle near the frontal margin; 

 epistoma abruptly depressed, short, truncate but scarcely paler; labrum feebly 

 punctulate toward the sides; eyes large Init not prominent; antenna' somewhat
