56 CLAVICORNIA. [Choleva. 



ii. Tliorax strongly punctured, with margins rather 



broadly explanate C. SPADICEA, Sturm. 



II. Thorax as broad as elytra, broadest at base . . . C. AGILIS, III. 



C. ans'ustata, F. Elongate, dark brown, with the head, and 

 sometimes thorax, dark, antennae long, reddish-testaceous or reddish- 

 hrown; thorax broader than long, rounded at sides, broadest before 

 middle, with posterior angles blunt, finely punctured ; elytra long, finely 

 punctured, with rather distinct striaj ; in the female the sutural angle 

 is produced into a small tooth ; legs long and slender, ferruginous ; 

 posterior trochanters of male more or less produced into a point, femora 

 with a small tooth on the first third. L. 5 mm. 



In moss, vegetable refuse, &c. ; local, and not as common as C. cisteloides. 

 MI\ Champion records it as rare in the London district, but it seems to be generally 

 distributed throughout England .from the southern to the northern counties ; it is, 

 ju'rhaps, most common in the Midlands ; Mr. Bold records it as less common in the 

 Northumberland district than C. cisteloides ; Scotland, rare, Forth district ; Ireland, 

 near Belfast and Dublin. 



C. Sturmi appears to be the male of C. angustata, or a variety of 

 the male ; it only differs in one or two very unimportant particulars, 

 such as the somewhat more elongate elytra, and the depth of the im- 

 pressions on the segments of the abdomen ; it cannot, however, be in 

 any way regarded as a separate species ; it has been recorded from the 

 London district, Mickleham, &c., by Mr. Champion and Dr. Power, 

 from Hampton-in-Arden by Mr. Blatch, and from Eepton by Mr. W. 

 Garneys. 



C. cisteloides, Frohl. This species may be distinguished from 

 C. angustata by its colour, which is darker, and usually pitchy or pitchy- 

 black ; the thorax is broadest in the middle and evenly rounded from 

 the middle towards apex and base ; the antennae are always more or less 

 darkened towards apex ; the posterior trochanters of the male are acumi- 

 nate and produced into a more or less projecting tooth on their inner 

 side, and the posterior femora of the male are rather plainly widened, 

 but without a tooth on their first third ; the sutural angles of the elytra 

 are not produced as in C. angiistata. L. 5 mm. 



In moss, dead leaves, vegetable refuse, by sweeping, &c. ; rathor common and 

 pcMKTally distributed throughout England and W;tles ; Scotland, local, Forth district; 

 it is probably common in Ireland. 



C. intermedia, Kraatz. This species appears to derive its name 

 from being intermediate between G. angitxtata and C. spadicea, being 

 shorter and broader than the former, and not nearly as robust as the 

 latter, from which, moreover, it may be distinguished by the sculp- 

 ture and the form of the margins of thorax ; from (7. angustata and 

 (' cisteloides it may be known by the pubescence of the elytra being 

 uneven at sides and apex with rows of raised hairs, and by the long, 

 pointed, gouge-shaped trochanters of the male; it must, however, be
