 tennarum longiusculo, curvato. Long. 4|- liii. S • 

 Head clothed with thick tawny-grey pubescence, vertex

 Ega. 



8. Hypselomus crassipes, n. sp. 



H. robustus, brunneus ; thorace lateribus pallidis ; elytris utrinque 



macula oblonga transversa cretacea ; pedibus crassis, nigris, tibiis 



posticis maris trigonis. Long. 8| lin. S . 



Head coarsely wrinkled, black ; antenniferous tubercles pro- 

 duced on the inner side into a stout spine {S). Antennas 

 scarcely so long as the body, bases of joints, from the fourth, 

 pale testaceous ; twelfth joint ( ^ ) short and twisted. Thorax 

 convex in the middle, without distinct tubercles, a short obtuse 

 tubercle on each side; above dark brown, sides dingy tawny 

 white, traversed by an indistinct dusky stripe. Elytra broad 

 and but slightly convex ; shoulders conically produced, base on 

 each side obtusely elevated and very coarsely granulate-punctate, 

 sides under the humeral projections also coarsely punctured, 

 rest of the surface faintly punctured ; dark brown, base dingy 

 tawny white ; each elytron beyond the middle ornamented with 

 a distinct oblong, transverse, chalky spot. Body beneath dingy 

 tawny ; abdomen black in the middle. Legs very stout, black ; 

 tibiae compressed ; hind tibiae ( ,$ ) dilated from the base, and 

 obliquely truncated at the apex ; claw-joint red. 



Tapajos. Apparently allied to H. fasciatus of Thomson; but

 in the legs.

 H. subelongatus, brunneo-fulvus, unicolor ; elytris modice attenuatis, 



humeris conicis ; anteunis gracilibus, articulis basi griseis. Long.
