The CorticaricB are x'eadily separable, even prima facie, fi'oin the Lathridii by 

 their more convex, ovate, pubescent, and less scul2)tm-ecl bodies, and by their 

 prothorax bciag broader and more rounded, — occasionally crenulated at its edges, 

 l}ut never margined like that of the latter ; neither are the angles at all produced, 

 nor is the disk flattened and costate. In pui-cly structiu-al characters, abnost the 

 only })oints in Avliich the groups differ inter se would appear to consist in the very 

 slight distinctive proportions of the joints of their respective antennae and feet, — 

 the former of which in Corticaria have the second articulation much less thickened 

 than the first, and the third perceptibly longer than the foiu-th ; whereas in 

 Lathridius the second joint is nearly as much iucrassated as the basal one, and 

 the third is distinctly shorter than the foui'th : whilst, as regards their tarsi, the 

 first articulation (if indeed my observations be correct) is always a little longer 

 than the second in those of the Corticarice, but shorter in those of the Lathridii. 

 In their habits, tlie members of the present genus are not so strictly subcortical as 

 those of the following one, — which in fact their less hardened and depressed forms 

 would seem to imply. They occur, for the most part, amongst heritage in grassy 

 spots, hybernating more commonly under moss and lichen on the trunks of trees 

 than beneath the bark.

Habitat Madcram, rarior, — a Rev''" Dom. Lowe prope Funclial primo detecta : sed plurima specimina 

 nuper collcgit Dom. Hartung, qui inter bolctos in truncis laurorum nascentes invenisse apud el. 

 Dohrn dicitur. 



C. elongate-ovate, rufo-piceous, pubescent, and very slightly shining. Head and prot/ioraj: deeply and 

 closely punctured : the latter with the edges rounded, and powerfully crenulated throughout ; with 

 a large, round, and deeply impressed fovea on the centre of the hinder disk. Elytra a little 

 darker and less rufeseent than the head and jirothorax ; rather nigosely striate-punctate. An- 

 teniue and leys rufo-testaceous ; i]ie former with their club infuscate. 



A large and well-marked species ; distinguished from the other Corticarice here 

 descriljed by the rather deep and closely-set punctures of its head and prothorax, 

 and by the greatly developed creuulations of the latter. It is apparently some-
