Genus CCL. — Xiletinus, Latreiile. . 



AntenncB inserted before the eyes, serrated in both sexes, composed of triangular 

 articulations, the second and third excepted, which are short and subglobose. 

 Palpi with the terminal joint subfusiform : h ead rather broad ; eyes globose: 

 thorax transverse, sinuated behind, and sometimes expanded laterally: elytra 

 sinuated at the sides : body short, ovate : legs rather long. 



The short ovate form of the Xiletini, combined with their broad 

 thorax, short, serrated antennse, and deeply striated elytra, of which 

 the lateral margins are sinuated, sufficiently distinguish them from 

 the Ptilini, with which they agree in their propensities to destroy 

 old wood. The species are rare in Britain.

Dull black, clothed with a fine silken pubescence : head punctulate. with an 

 obsolete elevated frontal line : thorax very convex, a little waved behind, the 

 disc punctured : elytra oblong-ovate, sinuated on the sides, the apex rounded, 

 the disc punctate-striate, the striae disposed in pairs, and the interstices very 

 finely punctured: legs and antennae pale rufous, the apex of the latter and 

 femora sometimes fuscescent. 



Rare : I possess a single example, taken near London in an old 

 post. " Spitchwcek, beneath moss." — Dr. Leach. " Cobham, on 

 palings, June, 1839.'''' — A. Cooper, Esq.
