52 COLEOPTERA. 



striae distinctly and all the interstices very coarsely punctured ; 

 underside greenish-black ; legs testaceous red or ferruginous, 

 according to its different degrees of maturity. 



Length 5 lines. 



Besides the general habit of this species, which sufficiently 

 distinguishes it from nigricornis (var. melanocornis), it differs 

 in the following important respects : — the mouth (often en- 

 tirely), palpi, and three joints at the base of the antennae, 

 are red. The form of the thorax is especially dissimilar, 

 being distinctly widest and more rounded in front below the 

 angles, and more obliquely narrowed behind, with the lateral 

 margins near the base not reflexed, the posterior angles also 

 being more rectangular ; the punctulation also of the thorax 

 and of the elytra is coarser, and the legs are always testaceous 

 or red. 



It is stated by the authors of the Faune Francaise that 

 the most reliable characters are to be found in the absence of 

 any coppery appearance on the head, and in the acute hinder 

 angles of the thorax ; but in the several European examples 

 which I have examined, I have observed a coppery tinge at 

 the back of the head in some of them, and cannot call the 

 posterior angles of the thorax, in any instance that has come 

 under my notice, acute. After all, the different form of the 

 thorax, and the general habit of the insect, offer the most re- 

 liable points of distinction. 



Two examples have been captured in England ; one by Dr. 

 Power, under the cliff, beyond Kemp Town ; and a second 

 by Mr. F. Bates, at Luccombe, in the Isle of Wight. 



Additional localities for the following species. 

 Nehria livida. Crevices in the cliffs at Cromer. 

 Calathus nubigena. Taken on the Pentland Hills, N. 

 B. : being the first time of its occurrence in Scotland.
