fourth together; pronotum in the ? not twice as broad at 
the base as in front; elytra greyish, often more or less 
brown between the nerves, membrane with a_ peculiar 
narrow dusky angulariy-shaped mark, which originates 
near the lateral margin below the cuneus, crosses the mem-

angles and runs towards the apex which it does not quite 
reach; tibize with fine black spines.

CRYPTOCERATA. 
NAUCORID. 
We have two genera in this family, which may be 
known by the following characters :—Broad-oval; head 
deeply sunk in the anterior margin of the pronotum, face 
horizontal or slightly declivous, antennz four-jointed, 
hidden below the eyes; scutellum triangular, large ; elytra, 
when developed, with the clavus well marked, membrane 
sometimes distinct, but in our British Mauweoris not dis- 
tinguishable from the corium; anterior femora more or 
less dilated and flattened, often greatly so, tarsi distinct 
(Aphelochirus) or apparently in one piece with the tibice 
(Naucoris), intermediate and posterior tarsi two-jointed 
and with two distinct claws.
