Cercus.'] CLAVICORNIA. 223 



entirely reddish-testaceous ; in doubtful cases the species may be 

 distinguished by the simple second joint of the antennae of the male ; 

 single female specimens of the two species are sometimes difficult to 

 determine. L. 1|-2| mm. 



Marshy places ; on Spircea ulmaria, 'Epildbium, Carex paniculata, &c. ; it has 

 also occurred in Cossus burrows in Sherwood Forest; local but occasionally abundant 

 where it occurs ; London district, rather common, Snodland (Kent), Coombe Wood, 

 Aylsham, &c. ; Amberley ; Maidstone ; Wingham, near Sandwich; Glanvilles Wootton; 

 Devon ; Wicken Fen, Cambridge ; Solihull, Knowle, Leamington, Repton and other 

 midland localities; Nocton, near Lincoln; Withington, Cheshire; Manchester; 

 Scarborough ; Northumberland district ; Scotland, recorded by Murray as "occasional," 

 but Dr. Sharp says that he does not know of its occurrence. 



C. rufilabris, Latr. Smaller than average specimens of either of 

 the two preceding, more elongate and less convex, clothed with very 

 thin and fine pubescence ; colour very variable, varying from almost 

 black with mouth parts red, to entirely reddish-testaceous ; head small, 

 finely and very thickly punctured, antenna? short, very much shorter 

 than in the preceding species ; thorax almost as long as broad at base 

 where it is almost as broad as elytra, narrowed from base to apex, deeply 

 and rather thickly punctured, with all the angles bluntly rounded ; 

 elytra thickly and strongly punctured ; legs and mouth parts always red. 

 L. lf-2 mm. 



Marshy places, on various plants, often on reeds and rushes ; common- and gene- 

 r-'lly distributed in the London district, and the southern and midland districts of 

 England ; rarer further north, and not recorded from Scotland. 



Between the Brachypterina and the Carpophilina come several im- 

 portant genera which are not represented in Europe, and occur almost 

 solely in the tropics ; among these may be mentioned Colastus, Bracliy- 

 peplus, and Conotelus, each of which contains a larger number of species, 

 and the curious genera Calonecrus, Cillceud, Ithyplienes, and Ortho- 

 gramma. 



CARPOPHILINA. 



The members of this tribe are distinguished from the Brachypterina 

 by their compact club, unilobed maxillae, and the very evident grooves 

 for the reception of the antennae ; they are chiefly confined to the single 

 genus Carpopliilus. 



CARPOPHXXiUS, Leach. 



This genus comprises about a hundred species, which are widely dis- 

 tributed throughout the world, but occur chiefly in tropical countries ; 

 only seven species occur in Europe, and several of these are probably 

 introduced ; three have been found in Britain. 



The larva of C. hemipterus is described by Ferris, Larves des Coleopteres, p. 45 ; it 

 very closely resembles that of Ips quadripunctata, of which he gives a full description 

 (p. 43), and chiefly differs in being rather more curved, and in having the last 

 abdominal segment slightly different.
