the epistoma flattened; antennae short, stout, joints 5-10 strongly 

 transverse, becoming progressively wider outwards. Prothorax 

 short, transverse, narrowed anteriorly, the hind angles obliterated, 

 the base feebly sinuate towards the sides ; densely, coarsely punctate, 

 the punctures here and there longitudinally confluent, with an 

 indication of a smooth median line towards the base. Elytra 

 elongate, considerably wider than the prothorax, subparallel in 

 their basal half, the marginal carina moderately prominent ; closely, 

 coarsely punctate. Beneath very densely, finely punctate. Legs 

 stout, the tibiae closely spinulose and setose. 

 Length 5-51 mm. 



Hab. Mexico {Truqui, in Mus. Brit.). 



Two females. Very like the single known specimen of 

 the same sex of T. arcuaticollis, but less convex, with the 

 prothorax broader behind and less sinuate at the base, 

 the vestiture almost wholly fuscous above. In one example 

 the elytra are rather broadly and abruptly rufescent at the 

 apex. 



8. Trichochrous truncatipennis, n. sp. 



(J. Elongate, rather broad, moderately convex, shining; nigro- 

 piceous, the antennal joints 2-5 obscure ferruginous; somewhat 

 thickly clothed with fine, pallid, adpressed hairs, without intermixed 

 setae, the marginal cilia of the elytra long, those along the lateral 

 margins of the prothorax short and closely placed. Head densely 

 punctate, the epistoma short and flattened ; antennae short, moder- 

 ately stout, joints 5-10 strongly transverse, 5 larger than 6, 6-10 

 subequal. Prothorax broad, transverse, convex, feebly rounded 

 at the sides, arcuately narrowed anteriorly, the base sinuate, the 

 hind angles obliterated; closely, finely punctate. Elytra slightly 

 wider than the prothorax, parallel in their basal half, sinuato- 

 truncate at the apex, the sutural angle sharp, the marginal carina 

 rather prominent, the epipleura a good deal widened anteriorly ; 

 closely, somewhat finely punctate, the punctures becoming a little 

 coarser towards the base. Fifth ventral segment unimpressed, 

 broadly truncate at the apex. Legs rather stout ; tibiae with several 

 spinules on their outer edge, those on the anterior and intermediate 

 pairs long. 



Length 4f , breadth 2 mm. 



Hah. Mexico, near the city {Edge). 



One male. Differs from all the allied forms in the trun- 

 cate apices of the elytra, the fine punctuation, the non- 

 setose, finely, uniformly pubescent upper surface, the
