ESTHESOPUS. 443 



the hind angles of the prothorax. Pro thorax broader than long, much wider at the base than at the 

 apex ; the sides moderately rounded, gradually converging in front, and straight and slightly converging 

 behind ; the hind angles rather short ; the entire surface somewhat sparsely, finely punctate, with minute 

 scattered punctures intermixed ; the base feebly sinuate on either side, without trace of sulci ; the 

 marginal carina entire. Scutellum somewhat convex in front. Elytra about two and two-thirds longer 

 than the prothorax, and of the same width at the base, slightly flattened on the disc, feebly rounded 

 at the sides, and arcuately narrowing from the middle to the apex, the humeri rounded ; deeply 

 punctate-striate, the interstices convex, flatter towards the suture, and somewhat thickly punctured. 

 Beneath thickly, rather coarsely punctate, with a few scattered minute punctures intermixed. Fourth 

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

 Length 5-6, breadth l|-2 millim. ( <5 $ •) 



Hob. Mexico, Chilpancingo in Guerrero (Edge, E. E. Smith), Cuernavaca in 

 Morelos (Salle, E. H. Smith). 



Found in plenty at Chilpancingo. This insect closely resembles E. nitidulus, but 

 differs from it in the distinctly mixed punctuation of the thorax, the larger punctures 

 being much finer and the smaller ones more numerous ; the body is less flattened above 

 and less parallel ; and the antennse are infuscate, except at the base. Some of the 

 specimens are more parallel than others, irrespective of sex. Single examples from 

 Capulalpam (Salle) and Yautepec (Edge) perhaps belong here, but they have the 

 antennae testaceous.

The type of E. apicatus has been kindly communicated by Dr. Candeze. It differs 

 from the specimens here referred to E. nitidulus in having the larger punctures on the 

 thorax a little more scattered and the smaller ones more distinct, and the elytra with 

 a large rufo-testaceous apical patch.
