144 COLEOPTERA. 



Kraatz and Schaum to the variety of N. nivalis with 

 pitchy black femora ; but among the Nebrice collected by 

 Mr. Squire in the Shetland Isles I find an individual, 

 which, as regards the proportions of the thorax and the 

 depth of the elytral striae, is intermediate between the two 

 specimens called by him nivalis and the insect now deno- 

 minated Gyllenhalii {nivalis, Dawson) ; it has, moreover, 

 the legs entirely rufous; hence the twofold doubt arises, 

 whether the specimens supposed by Mr. Squire to pertain to 

 N. nivalis, Payk., Kraatz, Schaum, are in reality referrible 

 thereto ; and, if they be so, whether it can be maintained as a 

 species. 



Patrobus lapponicus, Chaudoir? E. W. Janson, Proc. 

 Ent. Soc. 6 Sept. 1858, Zool. 6253 (1858). 

 Clova Mountains, Mr. Murray ; Shetlands, near Lerwick, 

 Mr. H. Squire; North Wales, Rev. H. Clark; North- 

 umberland, Dr. Power. Specifically distinct, I believe, 

 from the P. excavatus, Payk., Dawson, from which its 

 short broad and convex thorax, the coarse sculpture of that 

 segment and of the head, together with its deep black hue, 

 serve readily to distinguish it. Dr. Schaum informs us, 

 Naturgesch. d. Ins. Deutschl. i. 376 (1858), that Patrobus 

 Lappo?iicus, Chaudoir, is described from an unique specimen, 

 and requires further confirmation.
