between May and August, beneath the bark of various trees. 

 "Windsor Forest, under bark of rotten oak, 17th July, 1830." — 

 Mr. Westwood. 



Genus CLXIV. — Corticaria, Marsham. 



Antewice.rather longer than the thorax, the hasal joint large, glohose ; the second 

 smaller, elongate, ohconic; the third to the fifth more slender, elongate; the 

 three following shorter, gradually increasing; the ninth and tenth large, some- 

 what distant, cup-shaped ; the terminal one still larger, suhglobose. Palpi 

 robust; maxillary with the terminal joint conic, acuminated : head transverse, 

 narrowed before the eyes, which are lateral and prominent : thorax subcordate, 

 not angulated, immarginate: body oblong, slightly convex: elytra entire, 

 more or less ovate : legs short : femora incrassated ; tibice simple, slender at 

 the base ; tarsi elongate, slender, tetramerous ? 



Corticaria appears to be distinguished from Latridius principally 

 by the form of the antennae and thorax, the first having the third 

 joint not distinctly smaller than the follox ing, and the second more 

 elongate, the club stouter, with its terminal joint ovate; the thorax 

 is not subquadrate, and is not margined ; the body is more elongate 

 and convex, and more or less pubescent. 



Sp. 1. pubescens. Fusco-ferruginevs, longius pubescens, thorace longiore subcor- 

 dato, lateribus crenato, fovea mqjore posticd impresso, elytris punctato-striatis. 

 (Long. corp. 1— 1-j lin.) 



La. pubescens. Illiger.— Co. pubescens. Steph. Catal. 92. No. 987. 



Ferruginous-brown, or dusky-piceous, or pale testaceous, rather densely pubes- 

 cent; head obsoletely punctate: thorax subcordate, rather elongate, with the 

 lateral margins slightly rounded and obsoletely crenated, the disc rather 

 convex, thickly rugose-punctate, with a large rounded impressed fovea behind 

 the middle towards the base : elytra slightly convex, thickly punctate-striate, 

 the interstices also with a series of impressions, and in certain positions 

 appearing transversely rugulose ; especially towards the base: body beneath 

 entirely pitchy-black or rufo-ferruginous, with the breast and base of the 

 abdomen dusky: legs and antenna? ferruginous. 



Differs from the following in being larger, and by having the thorax more 

 elongate, Avith its sides more crenate, and the sculpture more deeply excised. 



Found in grassy places within the metropolitan district; also 

 beneath the bark of trees, in dunghills, &c. not uncommon. 



Sp. 2. crenulata. Fusco-picea, longius pubescens, thorace breviore rotundato, 

 lateribus obsoletius crenulato, elytris punctato-striatis, transversim-subrugosis.
