MEMBRACiS FOLIATA. 
Plate XXIV. Fig. 2. 
This insect affords a good example of a very remark- 
able genus, distinguished by having the pro thorax 
excessively elevated, compressed, and foliaceous, 
extending along the back like a kind of roof, under 
which the body of the insect is almost concealed. 
It is a native of Cayenne ; about four and a half 
lines in length (the figure being greatly magnified) ; 
the colour blackish-brown, the gibbous thorax with 
a broad arch, and band of white. The hemelytra 
are oval and much longer than the wings ; the legs 
long, flattened, and rather broad. 
Plate XXV. 
This plate is devoted to the representation of three 
species of the singular group named Centrotus, which 
approaches in essential characters to the preceding. 
Like it the prothorax is large and gibbous, produced 
in various fantastic forms over the scutellum, which 
is bidentate at the apex. “ Of all Nature’s works/* 
says Mr. Curtis, who has illustrated the genus b^ 
dissections of a British species,* “ amongst the insect 
tribes, this family is the most remarkable for the gro- 
tesque and extraordinary forms the species exhibit : 
the thorax being produced in the shape of horns of
