Wales, and, as a rule, common; Northumberland and Durham district, not common 
(Bold); Scotland, common, Solway, Tweed, Forth, Clyde, and probably other districts ; 
Ireland, near Waterford and Armagh, and probably widely distributed. 
C. equestris, I’. (viridis, L., nec F., teste H.R. W.). A large and 
conspicuous species, with the upper surface green and the under-side 
black, the margins of the abdomen being reddish-yellow ; antenne red 
for half their length, and the rest black; thorax sublunate, very finely 
punctured on disc, more strongly at sides, with posterior angles rounded; 
elytra raised towards base, sloped towards apex, confusedly, subrugosely, 
and moderately strongly punctured; legs entirely reddish-testaceous. 
L. 7-9 mm.

thorax obtuse, but marked, and the almost entirely black femora ; upper 
surface bright green, under-side black, abdomen with only the extreme 
border lighter; antenna reddish, fuscous towards apex; thorax sub- 
lunate, rugosely punctured, more coarsely at sides than on disc ; elytra 
confusedly punctured on disc, with more or less distinct rows of punc- 
tures at suture and shoulders, usually reddish-brown at base; legs, 
except femora, reddish-testaceous, L. 54-7 mm.

GC. hemispheerica, Herbst. (concinna, Steph.; anglica, Curt.). 
Round, subhemispherical, very convex, upper surface green or yellowish- 
green, under-side black with the abdomen entirely yellowish (a character 
that will at once distinguish the species); antenne testaceous, slightly 
darker towards apex; thorax sublunate, very finely punctured on dise, 
more distinctly at sides, posterior angles marked; elytra deeply and 
confusedly punctured, with a row of strong punctures towards margins, 
interstices smooth and shining, suture somewhat raised at anterior third ;
