Capside. 289 
like an inverted triangle on a stalk, its upper margin shorter 
than the sides; the left side, at the base, is very convex 
outwardly, and its upper margin denticulate, its lower 
margin produced into a long, curved, somewhat twisted, 
pointed process. From viridinervis the glabrous femora 
beneath will distinguish it. 
L. 5 mm. 
Woking, Surbiton and Chobham on Elms; Ilfracombe ; 
Folkestone on Ononis, Douglas and Scott. The yellow spots 
on the elytra described by Douglas and Scott are, I believe, 
due to some irregular development of the green pigment ; 
there are no traces of them in the other specimens that I have 
seen.

third; legs with a greenish tinge, anterior femora hairy 
beneath ; cell nerves of membrane yellow. 
L. 5 mm,

fourth together about as long as the second, third not twice
