Taken by Charles Turner, in December, 1860, near 

 Bridgnorth ; also, subsequently, and in large numbers, near 

 Lincoln, in the bark of a tree called " Bass" by the country 

 people, and which Dr. Power believes to be a species of 

 Tilia. 



This species is included as British in de Marseul's Cat. 

 Col. d' Europe (1863). 



It varies much in size ; the general magnitude being about 

 that of C. abietis, and the largest specimens not so large as 

 small C. hinodulus. Mature specimens are brownish-black, 

 with rows of strong greyish pubescence on the elytra ; and 

 the species is readily distinguished from all others found in 

 this country by the structure of its thorax, the tufted pro- 

 cesses surmounting which are limited to the upper and 

 anterior part, and do not extend to the lateral margins. 

 Moreover, instead of being scattered, so as to produce a kind 

 of granulated appearance, they are symmetrically arranged 

 in about three distinct rows placed in transverse curves, with 

 clear intervals between them ; and, in the median line, the 

 absence of tufts produces the appearance of a smooth space 

 connecting the outer spaces. 



It is placed by Redtenbacher in a section of the genus 

 wherein the anterior margin of the thorax is armed with 

 teeth ; and, under a moderately high power, these teeth can 

 be distinctly seen in the present insect ; assuming the form of 

 four small, closely-packed, longitudinal ridges, exactly in the 

 middle of the anterior margin.
