206 Femiptera-[leteroptera. 
little rarity from any of our other species. I took two off 
an elm hedge near Southwold in 1877,.the only locality I 
know for it. Dr. Power has also captured it. 
CARDIASTETHUS, Fieb. 
Very like the preceding genus, but distinguished by the 
longer head, which is much longer than the width of the 
vertex between the eyes; the pronotum in our British 
species is also much narrower in front. 
C. fascii-ventris, Garb. (testaceus, Perr., ete., nec 
Muls.).— Elongate oval, clear testaceous, clothed with 
very fine pale hairs, first joint of the antennz hardly reach- 
ing to the apex of the head; pronotum trapeziform, shining, 
anterior margin about half as long as the base, sides nar- 
rowly margined, nearly straight, base sinuate, dise with a 
shallow transverse impression, posteriorly finely wrinkled ; 
scutellum shining, transversely impressed behind the 
middle; elytra finely punctured and pubescent, of rather a 
greyer tint than the head and pronotum, dull, membrane 
dark smoky ; legs clear testaceous. 
L. 2 mm. 
Rare. Horsell and Chobham, Surrey ; Sheppey, Cham-
