128 INSECTA. 
This subgenus comprises the largest species, most of which are 
peculiar to Guiana and Brazil. Among them is the 
Hispe bordeé, Regn. Anim. Ed. I, pl. xiii, f. 5. Blood-red ; 
antennee, thorax, the sides excepted, and elytra, black; suture 
and external margin of the elytra, colour of the body; their 
middle is marked, in a variety, by a transverse line also red. 
This Insect is not rare in Brazil *. 
Hispa, Lin., Fab. 
The Hispz, properly so called, have short mandibles terminated by 
two or three small and almost equal teeth. America produces a great 
number of species. In some the superior surface of the body, and 
even a portion of the antennz are densely spinous. Such is the 
H. atra, L.; Oliv., Col., VI, 95,1, 9, called by Geoffroy the 
Chataigne noire, It is entirely black, extremely spinous, and a 
line and a half in length. In the environs of Paris, on the 
Grasses. 
The southern departments of France produce another species 
—the testacea, Oliv., Ib., 1, 77—closely allied to the preceding 
one, but fulvous. It is found on the Cisti. 
Cuauepus, Thunb. 
The Chalepi, if we take the H. spinipes, of Fabricius, as their type, 
differ from the Hispe proper in their long, slender, and arcuated 
legs, the two anterior of which are armed on the inner side, in the 
males, with a long spine. The third joint of the antenne is also 
proportionally longer. 
Some other Hispe—monoceros, Oliv.; porrecta, Schcenh.; 
rostratus, Kirby, &c.—remarkable for a projection on their head, 
resembling a horn, may perhaps form another subgenus. 
Cassipa, Lin. Fab. 
The Casside are distinguished from the Hispz by the following 
characters. The body is orbicular or almost ovoid, and in some few 
nearly square. The thorax, more or less semicircular, or forming 
the segment of a circle, entirely conceals and covers the head, or 
encloses it in an anterior emargination. The elytra, frequently 
elevated in the region of the scutellum, project beyond the body. 
The mandibles present four teeth at least, and the exterior maxillary 
lobe is at least as long as the inner one. 
The Imarip1a—Imatidiwm—of Fabricius, only differs from his 
Casside in their head, which is exposed and fixed in the emargina- 
tion of the thorax. In both the body is depressed, almost round, in 
the form of a shield or a little Tortoise, frequently elevated into a 
pyramid on the middle of the back, and overlapped all round by the 
sides of the thorax and elytra. The under surface is flat, so that 
these Insects seem as if glued to the spot to which they are attached.
