Exochomus.'] CLAVICORNIA. 177 



legs orange yellow ; the elytra are unicolorous, without spots ; the 

 abdomen is yellowish towards apex ; in the male the front part of the 

 head is yellowish, whereas in the female it is entirely black. L. 3|-4 

 mm. 



This insect is very doubtfully indigenous as British ; it is the Chilocorus 

 rufipes of Stephens' Illustrations and the Ch. JicemorrJioidalis of his 

 Manual ; he says of it, " I have hitherto seen two specimens only of this 

 very distinct species, one of which was captured near Windsor in June, 

 1816, and the other I obtained from the vicinity of Bristol" (I1L iv. 

 p. 375). 



XtHXZOBXUS, Stephens. 



This and the succeeding genus are distinguished from all our other 

 Coccinellidse by having the anterior coxal cavities open behind ; there 

 are about twenty species in the genus Rhizobhis, one of which occurs in 

 Europe, and the rest have been described from Australia, the Cape of 

 Good Hope, and Madeira, &c. ; it will probably be found to be a much 

 more extensive genus. 



1. litura, F. Elliptical} convex, shining, clothed with distinct 

 pubescence ; colour variable, entirely testaceous, or testaceous with an 

 oblique dark marking on each elytron, sometimes entirely pitchy-brown 

 or pitchy-black ; thorax rather finely, elytra distinctly, punctured ; legs 

 testaceous, more or less dark in the darkly coloured varieties ; antenna3 

 rather long and slender, terminating in a distinct club. L. 2-2 1 mm. 



At roots of grass, in 'moss, by general sweeping, &c. ; both inland and on the 

 coast ; very common throughout the whole of England from Yorkshire southwards ; 

 not so common further north ; Scotland, rather scarce, Solway and Forth districts ; 

 Ireland, near Waterford and Dublin, and probably common. 



COCCXDUXiA, Kugelann (Cacicula, Megerle). 



Four species are mentioned in the Munich catalogue as belonging to 

 this genus, two from Europe, one from North America, and one from 

 Northern China ; they are oblong and somewhat depressed insects, with 

 the anterior coxal cavities open behind.

C. rufa, Herbst. (pectoralis, F.). Oblong, distinctly pubescent,
