Oomptocerus, by Leconte and Horn with the Heteromera, but 

 more recently by those authors, and by Messrs. Fleutiaux and 

 Salle, with the Cioidse. 



The antennae are ll-jointed, the fifth to the tenth joints 

 dentate-lamellate internally, the apical joint compressed, nearly 

 round. The palpi with awl-shaped apical joints. The tarsi are 

 four-jointed, with a long claw-joint ; the first three joints nodi- 

 form, not pilose or spongiose beneath. The pronotum robust, 

 with distinct parapleurae and sharp margins : its surface has the 

 reticulate coriaceous sculpture of some Cioidse. The elytra sulcate, 

 with ridge-like acute interstices suggestive of an Aphodius. 



The anterior coxae are close together. The eyes are coarsely 

 granulate and not cut out ; the sculpture of the head is similar to 

 that of the thorax, and is suggestive of Uendecatomus.

Eutomus stjlcatus, sp. n. 



Eutomo micrographo similis et affinis, sed minor, riifo-brunneus ; 

 capite proihoraceque creberrime subtiliter alutaceis ; nntennarum, 

 articulis quinto ad decimimi longe dentato-laminatis, subpecti- 

 natis, apicali interne acuta ; elytris sulcatis, sulcis perobsolete 

 subrugosis. Long, vix 2 millim. 

 Hab. St. Vincent'(/:?. E. Smith). 



From E. micrographus, which this species very closely resembles 

 in form, sculpture, and structure, E. sulcatum is distinguished by 

 its much smaller size, its uniform brown colour, the longer lamellae 

 of the fifth to tenth joints of the antennae, each lamella from the 

 sixth joint being about as long as four joints of the funiculus, and 

 their paler colour, by the acuminate apical angle of their terminal 

 joint, and by the finer and less reticulate sculpture of the head and 

 thorax. 



About 20 examples of this species were obtained by Mr. Smith. 

 It rather closely resembles a small Aphodius found by him in 

 Grenada. The only other recorded species of Eutomus is a 

 Madagascar insect, which very probably is not congeneric.
