122 SERRICORNIA. [Cyphon. 



Marshy places, by boating and sweeping herbage, &c. ; usually recorded as 

 common and generally distributed throughout the greater part of the kingdom ; Mr. 

 Champion, however, mentions it as rare in the London district (Sheerness and Leith 

 Hill), and it is probable tint the succeeding species is often confounded with it. Dr. 

 Sharp records both species as common in Scotland. Ireland, Dublin, &c. 



C. nitidulua, Thorns. ( ? pallidiventris, Thorns.). Very like the pre- 

 ceding, but, as a rule, larger, with the upper surface more shiuing, and the 

 pubescence more scanty, and the elytra more sparingly but more strongly 

 punctured; the thorax also is somewhat more narrowed in front ; the 

 upper surface is also said to be less convex and the colour darker, but 

 these differences do not appear to be very reliable. L. 2-3 mm. 



Found under the same circumstances as the preceding, and apparently as widely 

 distributed ; it appears to be the commonest species in the London district, but less 

 common in the Midlands ; Scotland, common, Solway, Forth, Clyde, Tay, Dee, and 

 Moray districts ; it is probably common in Ireland. 



The C. fuscicornis and G. paJlidiventris of C. G. Thomson are re- 

 spectively the females of C. coarctatus and G. nitidulus ; they are dis- 

 tinguished from the male by having the elytra more thickly and finely 

 punctured in the neighbourhood of the scutellum. 



C. variabilia, Thunb. (pubescens, F. ; <$ nigriceps, Kies.). In size 

 and general appearance this species much resembles the two preceding, 

 but may be easily known by its longer and more oval form, and the 

 absence of raised lines on the elytra, which are, moreover, less depressed 

 on disc and more finely punctured, and have the shoulders much less 

 marked ; the prevailing colour is reddish-testaceous above, and fuscous 

 beneath, but is very variable, the suture and sides of elytra being often 

 more or less obscurely darker ; the head, as a rule, is dark, at all events 

 on vertex, and the antennae are dark with light base or light with dark 

 apex ; the pubescence is rather long and thick. L. 2-2i mm. 



Marshy places, by sweeping grass, &c. ; also at the roots of grass, and in moss and 

 flood refuse ; common and generally distributed throughout the kingdom. 



The C. nigriceps of Kiesenwetter appears to be the male of this insect, 

 which differs in being rather smaller and shorter, with the elytra more 

 sparingly punctured ; the G. nigriceps of Dr. Sharp's catalogue (1st 

 edition), however, is a different insect, and was afterwards named by 

 him G. punctipennis. 



C. punctipennis, Sharp (nigriceps, Brit. Cat., nee Thorns, et Kies.). 

 Allied to G. variabilis, but shorter, broader, and more convex, and dis- 

 tinguished from all the varieties of this species by its extremely short, 

 fine, and scanty pubescence ; the elytra, as a whole, are evidently more 

 sparingly punctured, although around the scutellum they are more 

 closely punctured ; in G. variabilia the punctuation is even; the elytra, 

 also, are shorter and broader in proportion thanin this latter species, 

 and have the shoulders more strongly marked ; the colour, as a rule,
