CARABIDAE. 11 



of tliis gemis except vi7-idifi Horn, vvhioli is tlie only one in our 

 i'luina witli the tiiorax wider than the head including the eyes. 

 In the larger species the nudes have four joints of the anterior 

 tarsi dilated, in tlie smaller but three. 



DiACHiLA. — I'vvo species occur in our fauna, arctica Gyll., 

 common to both Europe and America, and subjjolaria Lee., from 

 Hudson's Bay. The anterior tarsi of the male have four dilated 

 and spongy pubescent joints, and in suhpolariii the middle lemur 

 has a small tooth near the base. 



Blethisa. — Four joints of the anterior tarsi are slightly dilated 

 and spongy pubescent beneath in the male, and in quadricolUs 

 Hald., the anterior femora have an acute tooth beneath.

AntenniTe slender, base free, first four joints glabrous, first joint 

 elongate, third longer than second, joints 2-G with long bristles 

 in front. Eyes round, prominent. Head with a distinct neck 

 and one supra-orbital seta. Labruni moderately [jrominent, 

 arcuate in front. Mandibles thin, curved, acute at tip, without

 sion at base which bears long ciliae, inner lobe hooked at tip, 

 sparsely ciliate within, outer lobe with slender joints, palpi slender, 

 the last joint longer than the preceding and acute. Mentum 

 moderately emarginate with an obtuse tooth, basal suture distinct. 

 Ligula not prominent, slighly prolonged in front and bisetose, the 

 paraglossiB adherent in their entire length and not longer; the

 bisetose in front. Thorax transversely cordate, with a single 

 setigerous puncture at the side behind the middle. Body not 

 pedunculate, scutellum distinct. Elytra margined at base, sides 

 narrowly inflexed, lateral margin entire but with a distinct inter-

 marked, posterior coxae contiguous. Legs slender, middle and 

 hind tibiae spinulose externally, anterior tibia; deeply emarginate
