Of the other families belonging to the Heteropte-

for the following examples : — 
COREUS (SYRTOMASTES) PARADOXUS, 
Plate XX. Fig. 1 . 
Cimex paradoxus. Fair. <Jc. 
The genus Coreus is distinguished by having the body 
oval, the last joint of the antennae (w f hich consist of 
four articulations,) ovoid or fusiform, commonly shorter 
than the preceding. The subgenus Syrtomastes has 
the last joint of the antennae a good deal shorter than 
the preceding one, and nearly oval, while the latter 
is filiform and simple. Of this group S. margmatus 
is the best knowm species ; S, paradoxus is very 
similar to it, being of a grey colour, tinted in certain 
places with reddish brown ; the sides are fringed 
with ciliated membranous lobes, which give the in- 
sect a very singular appearance. It was first found 
by Sparmann at the Cape of Good Hope. 
CERBUS FLAVEOLUS.
