100 MANDIBULATA. — COLEOPTERA. 



beneath the bark of decaying or dead trees, and are usually found 

 in the spring. 



Sp. 1. ferrugineus. Rufo-ferrugineus, glaber, nitidvs, thorace profundi punctato, 

 elytris profundi punctato-striatis, antennarum stipite fusco. (Long. corp. 

 2— 2| lin.) 



Ly. ferrugineus. Paykul. — Rh. ferrugineus. Steph. Catal. 91. No. 973. 



Shining rufo-ferruginous, or piceous, glabrous ; head finely punctured, with a 

 fovea on each side : eyes dusky : thorax coarsely punctured, the disc rather 

 convex : elytra slightly convex, deeply punctate- striate : body beneath rufo- 

 ferruginous, rather finely punctate : legs pale testaceous : antennae with the 

 base and apex ferruginous, the middle pitchy-brown. 



Larger than the other species of the genus: differs from the three following in 

 having the thorax more convex and very coarsely punctate, the elytra also 

 more convex and rather deeply punctate-striate, the antennae dusky in the 

 middle. 



Not uncommon in the neighbourhood of London : found in 

 Battersea-fields, near Wandsworth, South Lambeth, &c. ; also at 

 Hertford and Ripley. " Among grass in woods, not common (near 

 Swansea)." — L. W. Dillwyn, Esq. 



Sp. 2. cylindricus. Cylindricus, ferrugineus, thorace subpunctato, elytris pro- 



fundius punctato-striatius. (Long. corp. 2^ lin.) 

 Rh. cylindricus. Steph. Catal. 91. No. 976.— Not of Panzer, 



Cylindric, ferruginous, shining, glabrous : head rather smooth : thorax slightly 

 elongate-quadrate, rather sparingly punctate : elytra deeply punctate-striate : 

 body beneath, antennae and legs ferruginous, the latter rather palest. 



From the preceding this species differs in being more cylindric, less punctate on 

 the head and thorax, and smaller. If Panzer's figure be correct, it cannot 

 represent an insect of this genus; the club of the antennae being triarticulate, 

 the apex of the elytra not truncate, the fovea dissimilar, &c: though as he gives 

 a magnified figure of the former it is doubtless given from nature : but not- 

 withstanding these discrepancies, my reference has been explicitly followed in 

 a work professing to be original. 



Found near London.

Sp. 3. rufus. Augustus, rufo-ferrugineus, nitidus, glaber, thorace tenuis punctato, 



elytris subtilissime punctato-striatis. (Long. corp. 2 lin.) 

 Co. rufa. Mar sham MSS.—Rh. rufus. Steph. Catal. 91. No. 975. 



Rather slender, rufo-ferruginous, shining, glabrous; the thorax very finely 

 punctate, the disc slightly convex : elytra a little convex, faintly punctate- 

 striate, the punctures somewhat distinct. 



In some respects this insect appears to resemble Rhy. cribratus of Gyllenhal, but
