the apex testaceous ; this is the v. Marshami, Weise (C. margintUu*, 

 Marsh.); but the insect presents tvery shade of variation between this 

 and being entirely fulvous, with the under-side and apex of antennae 

 black ; the species may be known from C. mi nut us by having the striae 

 almost effaced for posterior third, and the fact that the prosternura 

 has a long and sharp labial process ; in the male the antennae are as long 

 as the body, and the first joint of the anterior tarsi is strongly dilated 

 and half as long again as the third ; in the female these joints are nearly 

 equal. L. 2-3 mm. 



On young birches, &o., in woods ; also by sweeping heatb ; local, bnt rather 

 common in several localities ; Ashtead, Shirley, Weybridge, Forest Hill, Dorking, 

 Cobbam, Daren th Wood, Chatham, West Wickham, Southend ; Hastings ; Bourne- 

 mouth ; Glanvilles Wootton ; Devon ; Knowle ; Needwood ; Bretby, near Repton ; 

 Sherwood ; Chat Moss, Staffordshire ; it has not been recorded from further north. 



C. labiatus, L. Black, shining, with the base of the antennae, the 

 face and mouth parts below the antennae, and the anterior legs, except 

 the femora, and more or less of the posterior pairs, yellow ; thorax short, 

 very smooth and shining, scarcely visibly punctured ; elytra with strong 

 rows of punctures, which are much finer behind middle, and are almost 

 effaced for posterior third, prosternum with a central keel which is 

 raised in front and with the prosternal process slightly einarginate. 

 L. 2-3 mm. 



Male with the antennae longer and the anterior tarsi with the first 

 Joint dilated and longer than the third. 



On young birches, hazels, oaks, Ac. ; in woods and hedges ; generally distributed 

 and common throughout the greater part of England, and not uncommon in Scotland ; 

 it is the commonest of our British species, and often occurs in abundance. 



C. querceti, Suffr. (geminus, Wat Cat.). Very like the preceding, 

 but larger and rather longer, with the anterior legs entirely yellow, anil 

 the labial process of the prosternum much shorter ; as a rule the antennae 

 are entirely yellow or pitchy yellow, but this is not always the case ; 

 the intermediate and posterior legs are also yellow, the posterior femora 

 being broadly black on their outer side ; the first joint of the anterior 

 tarsi is elongate and only moderately dilated in the male, triangular in 

 the female. L. 3-3j mm. 



On oaks and birches; very rare ; as far as I know it has only occurred in Sherwood 

 Forest, where it baa been taken by the Rev. A. Matthews, Mr. Blatch, and others; 

 the C. <7tntn of Waterhouse's catalogue, which has been supposed to bo this 

 insect, has been recorded as taken in Devonshire on the barberry. 



C. exigiiuB, Schneid. (Wasastjernce, Gyll.). This is the smallest of 

 the British species; superficially it much resembles C. labiatus, from 

 which it may be known by having the thorax closely covered with 

 small and very fine striae, which are, however, by no means as pro- 

 nounced as in C. bilineatti*, and require a considerable magnifying 

 power to show them distinctly; the punctured striae of the elytra also
