TACHYPORID.E. — ATEMELES. 107 



rather depressed : thorax very broad, transverse, much narrowed anteriorly, 

 and deejily emarginate, the sides rounded and deeply bisinuated behind, with 

 the angles produced backwards into an acuminated spike-like process : 

 scutellum small, triangular : elytra very short, transverse, with the outer 

 angle of the apex deeply emarginate, the angle itself produced into a 

 tooth; abdomen ovate, with the penultimate joint simple: legs moderate. 



This and the two following genera differ from the other genera of 

 this family by having the terminal joint of the antennas elongate- 

 conic, and the hinder angle of the thorax more or less produced into 

 an acuminated spine, and the lateral margins are more or less flat- 

 tened and reflexed. The present genus appears to differ from its 

 allies by having the penultimate joint of the abdomen simple, and 

 the structure of the antennae slightly dissimilar.

Black, slightly opaque : head delicately punctured : thorax with a faint 

 dorsal furrow, and throughout thickly and delicately rugose-punctate, 

 black, with the margins somewhat elevated, and reddish-brown : elytra 

 quadrate, punctured, obscure castaneovis-brown, and slightly pubescent: 

 abdomen shining, with the apex pitchy-black: legs, mouth, and palpi 

 red-brown: antennae fuscous, with the basal and terminal joints dull 

 rufous. 



This rare species has been captured at " Swansea."" — Dr. Leach. 



Genus CCCCLXXXIX.— Atemeles, Dillwyn. 



Antennas filiform, the basal joint very stout, notched at the tip, the second 

 very short, third rather elongate-obconic, the remainder turbinate-subglo- 

 bose or campanulate, with the terminal one elongate subulate-conic. Palpi 

 maxillary rather long, filiform, with the terminal joint very minute: head 

 small, sessile, suborbiculate : forehead depressed : eyes small : thorax short, 

 transverse, with the lateral margins reflexed and angulated behind on each 

 side : body depressed, dilated : abdomen margined, depressed above, with 

 the penultimate joint emarginate, with a short style on each side, convex 

 beneath: legs slender; femora linear; tibiw subcylindric ; tarsi curved, 

 filiform. 



From Dinarda, the present genus, which is the genus Goniodes of 

 Kirby MSS. — a name used several years back by Nitzsch for a genus 

 of Nirmidae, — differs not only by having the penultimate joint of the 

 abdomen emarginate, with the sides produced into a styliform pro-
