RHYPAROCHROMUS, Curt. 
Byes nearly or quite touching the anterior margin of the 
pronotum, antenniferous tubercles distinct, antenne with 
the fourth joint as long or longer than the second, rostrum 
reaching to about the intermediate cox, ocelli small ; 
pronotum subquadrate, very little narrowed in front, sides 
sinuate behind the middle, narrowly and distinctly raised 
and carinated ; scutellum large; elytra with the sides sub- 
parallel, its membrane generally developed, but somewhat 
shortened in antennatus; lees with the anterior femora 
strongly incrassated and with a strong spine or group of 
spines towards the apex. This is a genus containing a 
good many species, of which we have only four in this 
country. Most, if not all, of the other European species 
are from the south, and not likely to occur with us.

with fine adpressed golden pubescence, antenniferous 
tubercles angularly produced at the sides, cheeks much 
shorter than the central lobe, their apices somewhat trun- 
cately rounded, antenne finely pilose; pronotum sub- 
trapeziform, anterior margin emarginate, sides slightly 
rounded in front then sinuate behind the middle, margins 
reflexed, base largely emarginate, surface punctured with 
large punctures, disc with a deep transverse impression
