180 MANDIBULATA. — COLEOPTERA. 



Subglobose, glossy black, with the antennae, thorax, and legs rufous; the elyta 

 and thorax obsoletely but dispersedly punctulate ; body black beneath. 



The rufous antennae and legs distinguish this from the following species, with 

 which it agrees in having a rufous thorax. 



Rare. I possess one specimen from the Marshamian cabinet, 

 and another taken at Colney-hatcli wood in June. 



Sp. 2. globus. Plate xv. f . 4. — Globosum, nigrum nitidum vage punctulatum, 



thorace rufo, antennis pedihusque rufo-piceis. (Long. corp. 1^ lin.) 

 An. globose. Paykul. — Ag. globus. Steph. Catal. p. 70. No. 752. 



Subglobose, shining black, irregularly punctulate, the punctures distinct; thorax 

 very convex, bright shining red, and finely punctured: legs pitchy-red, with 

 the apex of the tibiae and the tarsi palest : body pitchy-black beneath, with the 

 apex pale testaceous: antennae deep rusty -brown, with the terminal joint 

 bright ferruginous. 



Differs from the last by the darkness of the legs and antennae ; by the terminal 

 joint of the latter being paler than the rest; — the body being piceous below, 

 and the anus testaceous. 



Not common ; found occasionally in woody places, in rotten trees, 

 or amongst putrid leaves. 



Sp. 3. ferrugineum. Globosum, rufo- ferrugineum, nitidum, tenue punctulatum, 



antennis pedibusqae pallidioribus. (Long. corp. if lin.) 

 Ag. ferrugineum. Sturm. — Steph. Catal. p. 70. No. 750. 



The globose form of the preceding : above of a glossy testaceous or ferruginous- 

 red, with the eyes fuscous : the thorax very shining and scarcely punctured, 

 broad, the lateral and hinder margins greatly dilated, so that when the insect 

 is in a walking position the thorax appears remote from the elytra : the latter 

 finely punctured throughout, with a single stria near the suture, abbreviated 

 anteriorly : body pale testaceous beneath : legs very short and pale testaceous : 

 antennae ferruginous : the eighth joint rather larger than the seventh, the 

 remainder considerably larger and a little dusky. 



Distinguished by its pale head and elytra from the two preceding insects, and 

 from the following by the same characters, the smallness of its scutellum, and 

 larger size. 



My specimen of this species was captured at Coombe-wood, be- 

 neath the bark of an old ash. 



Sp. 4. atrum. Atrum nitidum, subtilissime punctulatum, antennis pedibusqure 



rufo-piceis, scutello magno. (Long. corp. 1 — 1^ lin.) 

 Anisotoma atrum. Paykul.— Kg. atrum. Steph. Catal. p. 70. No. 751. 



Deep shining black, very thickly and finely punctulate : head large, rather smooth, 

 mouth dull testaceous : thorax with its lateral margins considerably dilated, 

 above very convex, scarcely punctulated, black, with the lateral and some- 

 times the posterior margin pellucid and rufescent : scutellum large, glossy,
