This genus is made for Micropsephus hemisphoericus 

 Champ., and a new species, which differ from Micropsephus 

 by tlieir very short antennae and the absence of the im- 

 pressed arched stria upon the pronotum, in the occurrence 

 of which Micropsephus resembles Trichopsephus. The 

 claws of the older genus are cleft, a condition which I 

 believe has not hitherto been found in any other Eiidomychid 

 genus, and the antennal footstalk consists of eight very stout 

 and well-marked joints, but in the new genus these joints 

 are very nnich reduced in size and development and mimber 

 only five (in hemisphoericHs) or six (in the new species).

Hah. Antilles : St. Vincent, Leeward side, Kingstown; 

 Grenada : Balthasar, Windward side. 



Nine specimens were found by Mr. H. H. Smith. 



In size and general appearance the species is exactly 

 similar to M. hemisphoericus Champ., from which it is 

 easily distinguished by its red head and thorax. It differs 

 also in the peculiar thickening of the sides of the pronotum 

 in front and in the smaller relative size of the terminal 

 joint of the antenna, besides possessing an additional 

 minute joint in the exiguous footstalk.

This genua forms an interesting link between the New
