 paulo emarginatis et thorage coaptatis, ntrinque foveis rotundatis serie-

Cape San Lucas, Lower California ; ^Ir. Xantus. This genua 

 differs from Triorophus by the superciliary ridge being one and 

 single above the eyes, by the antenna- being shorter and less 

 slender, by the last joint of the maxillary palpi being doI longer 

 than its width, by the eyes being larger and distinctly emarginate, 

 by the thorax not being rouuded, by the elytra being closely 

 applied to the thorax, with the humeral angles distinct, and 

 finally by the tarsi being pubescent beneath and setose. The 

 large punctures of the elytra form eight discoidal and one 

 marginal series, and there is a scutellar stria composed of three 

 or four puuctures. The epistoma is trilobed as strongly as in 

 Triorophus, the middle lobe being angulated at tip as in that 

 genus: the mentum is more flat than in Triorophus, being hex- 

 agonal, and transverse, with the lateral angles distinct, and tin- 

 front margin feebly emarginate ; but the difference in this respect 

 is neither obvious nor important.

366. Ell. punctulatlllll. Alatuui, elongato-ovale, piceum fere 

 opacum, confertim subtilius subscabro-punctatum, elytris striis punc-

Cape San Lucas, Lower California ; Mr. Xantns. The body 

 is elongate oval, moderately convex, and without lustre ; the head 

 and thorax are punctured, the punctures being slightly scabrous; 

 the thorax is nearly twice as wide as its length, narrowed in 

 front, strongly rounded on the sides, broadly emarginate in front, 

 and slightly rounded at the base ; the front angles are acute and 

 the hind angles obtuse, but not rounded. Elytra scarcely wider 

 than the thorax, with rows of punctures, forming stria- which are 

 very indistinct and not at all impressed; punctures of the inter- 

 stices nearly as large as those of the stria-, Borneo hal scabrous. 

 Body beneath rufo-piceous ; antenna;, l.-gs, and epipleura nearly 

 ferruginous; anterior tibiae slightly and gradually dilated, Bcarcely 

 serrate, external apical angle acute.
