200 MANDIBULATA. — COLEOPTERA. 



Black, opaque, depressed : clypeus somewhat angular, with three obsolete tu- 

 bercles : thorax rather coarsely punctured throughout, immaculate : elytra 

 piceous black, punctate-striate, the striae rather wide but shallow, the inter- 

 stices impunctate : legs black, with fulvous tarsi. 



Differs from the two preceding in being smaller, of an obscure black colour, with 

 the elytra piceous black, and punctate-striate, with the interstices impunctate, 

 the legs black, and tarsi fulvous. 



Found in Norfolk, and I believe not within the metropolitan 

 district. 



h. With the clypeus not distinctly tuberculated. 



1. The body depressed, with the clypeus entire. 



Sp. 35. rufipes. Oblongus, piceus, subtus dilutior, clypeo thoracisque disco Icevibus, 



elytris striatis, tibiis anticis externe tridentatis. (Long. corp. 4 — 5 lin.)

 No. 1149. 



Oblong, pitchy : clypeus very large, rounded anteriorly, angulated towards the 

 eyes, smooth, black : thorax smooth, shining, with the lateral edges a little 

 punctate: elytra rather long, shining piceous, striated, the stria? obsoletely 

 crenate-punctate, the interstices convex, smooth, but obscurely punctate to- 

 wards the base: body beneath, antenna 1 and legs rufo-ferruginous: anterior 

 tibiae tridentate. 



Variable in colour: known from the following, which it greatly resembles in size 

 and habit, by having the anterior tibia? strongly tridentate. 



Extremely abundant throughout the metropolitan district, and I 

 believe in most parts of the country. I have taken it near Dover, 

 at Brighton, in the Isle of Wight, &c. ; and it occurs in Norfolk, 

 Suffolk, Devonshire, Dorsetshire, &c. " Rottisham." — Rev. L. 

 Jenyns. " Near York and Newcastle." — W. C. Heroitson, Esq.

Sp. 36. muticus. Oblongus, piceus, subtus dilutior, clypeo thoraceque Icevibus, 

 elytris striatis, tibiis anticis externe subunidentatis. (Long. corp. 5 lin.) 



Ap. muticus mihi. Steph. Catal. 111. No. 1150. 



Oblong, piceous: clypeus large, rounded anteriorly, impunctate; its margin 

 rufescent: thorax transverse, impunctate: elytra oblong, shining piceous, 

 striated, the striae faintly punctured, the interstices rather convex and not 

 in the least punctate at or towards the base: body beneath, antenna? and legs 

 rufo-piceous, the anterior tibiae obscurely unidentate. 



The obsoletely unidentate anterior tibia? of this species form its chief point of 

 distinction from the last described, of which it is not improbable it may be 

 only a monstrous variety ; though many specimens were taken by Dr. Leach 

 in the north of England.
