144 ENDOMYCflmE. 



guishing character is, however, the rather deep and confluent puncturing of the elytra. 

 The thorax is short and transverse, at the base more than twice as wide as long; the 

 sulci are linear, and rather more arcuate than in B. hemisphwricus. 

 Eight specimens. 



5. Ehymbus pallidulus?

 Hab. Beitish Hondueas, Belize (Blancaneaux). — Beazil \ Eio Janeiro. 



In three specimens from Belize the antennae have the club-joints shorter than in 

 B. hemisphcericus, the punctuation of the elytra is very fine and close, and the thorax is 

 short. The identification is, however, uncertain. The species appear very little dif- 

 ferentiated and require revision. 



Section B. Antennas ten-jointed. 



6. Ehymbus fibulatus. 



Orbicularis, rufo-piceus, nitidus, sutura et marginibus indistincte dilutioribus ; antennis capitis protho- 

 racisque longitudine, clava valida, nigra, articulo ultimo oblongo, apice summo rufo ; elytris creberrime 

 minute sed distincte punctatis. Long. 2 millim. 



Hab. Mexico, Toxpam (SalU). 



This little Bhymbus is very near to a species from Guiana, which I have described 

 [Endom. Recit. p. 56] under the name B. seminulum ; but it has the elytra less 

 distinctly margined with yellow, and the punctuation much closer and finer; the 

 pubescence is also very distinct in B. fibulatus and hoary. The antennae are rather 

 long, and have the last four joints with part of the preceding one black. The thorax 

 is transverse, its sulci distinct, and a marginal line on the base between them. 



Two specimens. 



7. Ehymbus vestitus. 



Orbicularis, rufo-piceus, nitidus, aureo-pilosus ; antennis concoloribus, articulo ultimo subquadrato; prothorace 

 transverso, sulcis basalibus latiusculis, extus carinatis ; elytris vix perspicue punctatis. Long. 1 J millim. 



Hab. Panama, Volcan de Chiriqui 3000 feet {Champion). 



Easily distinguished from B. fibulatus by the shorter and less stout antennas, and by 

 their entire rufo-piceous colour. The sulci of the thorax are also wide depressions 

 extending half across the thorax, edged on the outside with a short but somewhat 

 plicate carina. The elytra are unicolorous, thickly clothed with a shining, pale 

 golden, pilose pubescence. The thorax (in the single specimen obtained) is a very 

 little deeper in colour than the elytra. The puncturing of the latter is very fine, 

 requiring the microscope to see it.
