Coleopterological Notices, VI. 515 



where the sides are broadly rounded, thence becoming distinctly convergent 

 and very feebly arcuate to the apical angles, which are slightly obtuse but very 

 distinct and scarcely at all rounded, convergent and feebly sinuate very near 

 the basal angles, these being obtuse but distinct; apex and base equal, broadly, 

 feebly arcuate; disk finely and sparsely punctate, not rugose laterally. Elytra 

 two-thirds longer than wide, nearly one-fourth wider than the prothorax, the 

 sides subparallel, feebly sinuate behind the unusually tumid humeri; apex 

 evenly and not l)roadly rounded; disk finely but strongly, not very densely 

 punctate. Abdomen densely punctulate, not very conspicuously cinereo-f)ubes- 

 cent. Length 3.2 mm.; width 1.1 mm. 



California (Sta. Barbara). Mr. Dunn. 



This species may be distinguished from the preceding by its 

 much more slender form, anteriorly convergent sides of the pro- 

 thorax and shorter erect setiie of the elytra, as well as by the 

 more abundant cinereous pubescence, which last however is a vari- 

 able character. It is represented by a single female example. 



60. T. iiiexicanus n. sp. — Oblong, not very stout, strongly convex, 

 feebly shining, black; legs pale rufo-ferruginous throughout; antennae in great 

 part pale; pubescence rather long and coarse but sparse, whitish, subdecum- 

 bent, darker and less conspicuous in an elongate streak on each elytron near 

 the suture; body bristling above with numerous long erect blackish setse. 

 Head nearly four-fifths as wide as the prothorax, strongly and rather closely 

 punctured, the interspaces smooth and polished throughout ; frontal impressions 

 feeble; epistoma transverse; labrum strongly rounded, in great part pale; eyes 

 moderate in size and rather prominent; autemite somewhat long, distinctly ser- 

 rate. Prothorax unusually elongate, only very slightly wider than long, sub- 

 globularly convex, the sides broadly rounded behind, sensibly convergent and 

 nearly straight anteriorly, the apex distinctly narrower than the base, both 

 arcuate; angles obtuse and scarcely distinct, the posterior apparently broadly 

 rounded; disk rather coarsely, deeply and closely punctate, not rugose at the 

 sides. Etytra two-thirds longer than wide, only slightly wider than the pro- 

 thorax, parallel and straight behind the humeri which are some\\hat promi- 

 nentlj' tumid; ape.x evenly, not very broadly rounded; disk coarsely, strongly 

 and densely punctured. Ahdomen and legs rather densely cinereopubescent. 

 Length 2.7.5 mm. ; width 1.05 mm. 



Mexico (northern). Cab. Levette. 



This species is wholl}- different from any of those with which 

 it must be associated in this revision, especially in the elongate 

 and more globular form of the prothorax and coarse close punc- 

 tuation. The description refers to the male, in which sex the 

 fifth ventral is truncate as usual. Mexicanus is represented by 

 two similar male examples which cannot apparently be associated
