158 MANDIBULATA. — COLEOPTERA. 



Dend. rotundatus. Steph. Catal, 102. No. 1077, note.— Hi. piceus. Marsham. 



Ovate, black, a little depressed, and sparingly punctate throughout: forehead 

 convex : thorax scarcely margined, with the entire surface finely punctured : 

 elytra glossy, punctate throughout, the punctures finer and more distinct on 

 the disc anteriorly; each with four oblique abbreviated punctate striae reaching 

 beyond the middle, and a very short one on the shoulder, the inner one re- 

 curved, but not descending down the suture. 



Smaller than the foregoing, from which, among other characters, it differs in 

 wanting a sutural stria, in having the strise more elongated, in colour, &c. 



Rare: I have taken one specimen in the neighbourhood of 

 London, but forget the exact locality. " Swansea and Norfolk." —

Genus CLXXXIV. — Dendrophilus, Leach. 



Antenna? with the basal joint long, robust, clavate, the second about one-fourth 

 the length of the first, less robust and clavate; four following somewhat monih- 

 form ; the two upper larger ; the remainder forming an oval, rather solid 

 triarticulate club. Palpi unequal, with the terminal joint elongate: head 

 small, rounded : thorax short, produced in the centre beneath : elytra truncate, 

 nearly covering the abdomen : body more or less convex : legs short : tibia? 

 compressed, the anterior dilated externally, and subserrated ; the four posterior 

 less dilated, the outer edge slightly spinulose ; tarsi contractile, simple. 



The typical Dendrophili differ from the Histri in habit, by in- 

 habiting beneath the bark of dead or decaying trees, though the 

 less typical ones affect the putrid remains of animals and other 

 refuse : they may be known from the insects of the preceding 

 genus by the dissimilarity in the proportions of the articulations of 

 the antenna?, by having the tibise dilated and simple, the elytra 

 nearly covering the abdomen : — the genus probably requires subdi- 

 vision, the insects of the first section differing materially in habit from 

 those of the second, which are intimately allied to those of the next 

 genus, living beneath the bark of trees, as above noticed. 



A. With the body considerably elevated, and convex, the elytra striated.
