110 MANDIBULATA. — COLEOPTERA. 



thickly punctulate, with a somewhat deep, transverse-ovate fovea behind the 

 middle at the base : elytra slightly convex, testaceous, rather obsoletely striated, 

 the interstices slightly elevated: body beneath piceous: antennae and legs 

 pale. 

 Differs from the two preceding by the truncated base of the thorax, as well as 

 in colour, sculpture, &c. 



From the Marshamian cabinet. 



Sp. 11. similata. Brevis, convexa, fusco-ferruginea, pubescens, thorace trans- 

 verso, acutangulo,foveis tribus impresso, elytris texatis. (Long. corp. ^ lin.) 

 Lat. similatus. Schuppel. — Co. similata. Steph. Catal. 93. No. 997. 



Short, convex, rusty-brown, pubescent, with the thorax transverse, the angles 

 acute, the disc with three fovea, rounded or oblong, and moderately deep : 

 elytra slightly convex, testaceous-brown, shining, with rows of hairs, punctate- 

 striate, the interstices narrow, elevated, with transverse wrinkles. 



The three foveae on the thorax, and dissimilarity of the sculpture on the elytra, 

 and its smaller size, distinguish this species. 



Found, though rarely, near London. 



Genus CLXV. — Latridius, Herbst. 



Antennas scarcely longer than the thorax, the basal joint very large, globose ; 

 the second ovate, larger than the third, which is very short, and, with the five 

 following slender, the third, seventh, and eighth being ovate ; the ninth and 

 tenth are large, cup-shaped ; the eleventh still larger, subglobose, acuminated. 

 Palpi short, robust; maxillary with the terminal joint ovate, small: head 

 subovate, slightly narrowed anteriorly: eyes lateral, prominent: thorax sub- 

 quadrate-cordate, slightly angulated and distinctly margined, narrower than 

 the elytra, which are suboval : body slightly depressed : legs rather elongate : 

 femora incrassated; tibia simple, subclavate; tarsi tetramerous? 



Latridius may perhaps be most readily detected from Corticaria, 

 by the structure of the thorax, which is generally more or less 

 angulated and very distinctly margined : but there are other obvious 

 characters, such as the dissimilarity in the structure of the antennae, 

 form of body, &c. The species are minute, though, notwithstanding, 

 their characters are sufficiently evident ; but, like most genera com- 

 posed of minute species, the present has been much neglected, as 

 may be instanced from the circumstance of its not having received 

 any augmentation beyond the mere list of species contained in my 

 Systematic Catalogue, in two separate publications, professing to 

 be drawn up from original materials, whereas twice the number
