Pityoplithorus.l RHYNCHOPHORA. 435 



brown, moderately shining, antennae and legs reddish brown; thorax 

 longer than broad, hardly narrowed in front, apex bluntly rounded, 

 anterior exasperations concentrically disposed, punctuation of hinder 

 part fine and scattered ; elytra produced at apex not obtusely rounded 

 with fine punctuation ; the apical depressions are distinct, deep and 

 rather dull, with their outer margins raised, convex and shining, without 

 punctures, but with distinct setigerous tubercles, which are also present 

 on the raised sutural margins. L. 1|-H mm. 



As before remarked, no authentic British specimens of this species are 

 known, as all that have hitherto been examined must be referred to one 

 of the two preceding ; it is, however, very probable that it exists in our 

 collections ; it is especially attached to the spruce-fir. 



The longer shape, brighter colour, and finer punctuation, as well as the 

 acuminate elytra will distinguish this insect from either of the other 

 species). 



The members of the genus can be taken in localities where they occur, 

 by examining the smaller terminal shoots and branches of Conifer 

 brushwood ; most of the species breed in these and do not touch the 

 bark of large branches ; P. micrograpTtus, however, appears to be an 

 exception to this rule. 



XYLOCLEPTES, Ferrari. 



This genus contains three species, one of which is found in Europe, 

 and the others have been described from Venezuela and Bogota; 

 X. lisj'inus, the single European species, is exclusively attached to 

 species of Clematis ; it may be known by having the second joint of the 

 club of the antenna? crescent-shaped and completely embracing the sides 

 of the first ; the funiculus is five-jointed; the scutelrum is indistinct, 

 and the apical portion of the elytra is strongly inflexed in the male and 

 feebly inflexed in the female. 



X. bispinus, Duft. Cylindrical, chestnut brown, shining, clothed 

 with rather scanty long upright greyish hairs, which are very distinctly 

 visible if the insect is viewed sideways ; thorax longer than broad, 

 scabrous in front, with the angles rounded ; scutellum scarcely dis- 

 tinct; elytra with moderately fine and rather close punctured strise. 

 L. 2-3 1 mm. 



Male with the thorax shining and diffusely punctured behind ; apex 

 of elytra much inflexed, raised at suture and armed with a large sharp 

 tooth. 



Female with the thorax dull and shagreened behind, except on the 

 central line ; apex of elytra feebly inflexed with the suture and raised 

 edges projecting and finely tuberculate.
