200 THE CANADIAN ENTOMOLOGIST. 



below for the benefit of Canadian students who may not see Captain 

 Casey's books. The beetle occurs sparingly, under loose bark or under 

 logs on the ground, along the mainland of British Columbia from Fort 

 Simpson to Rivers Inlet, and probably farther, if sought for. I have 

 never met with a specimen on the Queen Charlotte Islands. 



The following is Capt. Casey's description : 



" Brenmis insular is, n. sp. — Elongate, rather feebly ventricose, 

 shining throughout, black throughout the body and legs, the elytra 

 rather dusky cupreo-violaceous, with narrow and bright aeneous side 

 margins. Head rather stout, moderately elongate, the vertex almost 

 smooth, the broadly impressed transverse nuchal constriction rather 

 pronounced \ gen?e feebly developed, with the angular notch small and 

 inconspicuous ; supra-orbital ridges moderately strong and inwardly 

 inclined at the antennae, fine posteriorly ; antennas slender, moderate in 

 length, the basal joint distinctly thicker, claviform, not as long as the 

 next two, the seta at apical eighth. Prothorax well developed, scarcely 

 as long as wide, moderately dilated and broadly rounded throughout 

 anteriorly, the sides not more strongly rounded before, but becoming 

 gradually oblique behind ; the middle, to the base, with a scarcely visible 

 ante-basal sinuation ; angles much more than right, and bluntly rounded ; 

 base wide, more than half the maximum width and fully as wide as the 

 head ; disk feebly convex, the median line strong ; sublateral impressions 

 deep, extending far before the middle ; reflexed margins rather fine. 

 Elytra elongate-elliptical, fully half longer than wide, nearly three and a 

 half times as long as the prothorax and two and a third times as wide ; 

 humeri evenly and obliquely rounded ; reflexed margins ample but 

 rather finely punctate ; disk strongly, evenly convex, the stripe deep and 

 broadly impressed, rather uneven, obscurely punctate, readily traceable 

 throughout the width, the intervals convex, much broken up toward the 

 sides and finely so toward the apex. Legs very slender. Length 17.5 

 mm.; width 6.8 mm. 



"Queen Charlotte Islands. [This is an error. See above. — J. H. K.] 

 "This fine species is founded upon a single perfect specimen recently 

 sent to me by Mr. Fletcher and probably taken by Mr. Keen. It is a 

 female, but the species will be readily known from tnarginaiiis by its 

 much larger size, more elongate and convex elytra, larger and less 

 posteriorly narrowed prothorax, with the sides less sinuate toward base, 

 and several other characters."
