Hab. 1 Mexico (coll. Janson, ex Laferte and Candeze). — Colombia 1 2 3 ; Venezuela 3 . 



One of the two examples doing duty for E. murinus, Cand., in the Janson collection 

 is certainly referable to E. troglodytes, and there is an old specimen in the same 

 collection, from that of Laferte, labelled " Mexico (Deyrolle)" apparently belonging 

 to it ; but the locality " Mexico " requires confirmation. The thorax is sparsely and 

 moderately finely punctate throughout, with minute intermixed punctures, and is 

 without trace of coarse punctures near the base. The elytra are a little wider 

 than the thorax, somewhat rounded at the sides, with the striae shallow and the 

 interstices almost flat towards the suture. 



4. Esthesopus ebeninus, 



Moderately elongate, robust, flattened above, sbining, sparsely clotbed witb fine fusco-cinereous pubescence ; 

 above and beneath black, the antennae, femora, and tibia? piceous, the tarsi testaceous. Head thickly, 

 coarsely punctate, with minute punctures intermixed ; antennae slender, short, scarcely reaching the hind 

 angles of the prothorax. Prothorax moderately convex, broader than long, much wider at the base than 

 at the apex, the sides almost straight and very slightly converging behind, and gradually and arcuately 

 converging in front; the hind angles moderately produced ; the surface closely punctured, the punctua- 

 tion consisting of intermixed rather coarse and very fine punctures, the larger ones somewhat closely 

 placed, becoming coarser and more crowded towards the sides and apex ; the base sinuous on either side, 

 without trace of sulci; the marginal carina complete. Scutellum large and feebly convex. Elytra 

 two and one-half times the length of the prothorax, and not wider than it, subparallel from a little below 

 the shoulders to beyond the middle, and arcuately narrowing thence to the apex, slightly narrowed in 

 front, the humeri subangular ; punctate-striate, the interstices feebly convex, flat on the disc, and 

 thickly, very distinctly punctate. Beneath closely punctate, the punctuation consisting of fine and 

 moderately coarse punctures intermixed, the larger ones on the propleurae coarse. Fourth tarsal joint 

 strongly lamellate. Claws rectangularly dilated from the middle to the base.

Hab. Mexico, Chilpancingo in Guerrero (Hbge). 



One specimen. This species may be known from most of its allies by the infuscate 

 femora and tibiae, a character also to be found in E. carbonarius, Cand., from Cayenne. 

 It is perhaps nearest to E. hepaticus, from which it differs in having the thorax less 

 parallel, with the larger punctures coarser and closer, the elytra slightly narrowed at 

 the base and more obtuse at the apex, the legs not entirely testaceous, &c. 



5. Esthesopus fuscicornis. 



Moderately elongate, rather robust, shining, somewhat sparsely clothed with fine cinereous or fusco-cinereous 

 pubescence; black, the anterior angles of the prothorax, testaceous, the head more or less rufescent in 

 front, the elytra sometimes piceous or brownish, with the humeri indeterminately paler ; the antenna: 

 piceous or brown, with the basal one or two joints testaceous, the legs testaceous. Head thickly, rather 

 coarsely punctate, with a few very fine punctures intermixed : antennae slender, short, about reaching
