Fair. Syst. Eleuth. — Olivier , vi. No. 97? pi. 5, fig. 86. 
This curious species lias the thorax very much 
dilated on each side into a thin foliaceous membrane, 
which is dentate round the margin. A similar ex- 
panded portion, likewise dentate on the edge, sur- 
rounds the elytra ; the latter have the anterior half 
green, and the hinder part reddish brown. The 
under side of the body is dull yellowish red. Like 
the preceding species, it is a native of Java. 
CASSIDA PERFORATA. 
PLATE XXVIII. Fig. 5. 
Fair, Syst. Entom . — Olivier , vi. No. 97? pi. 4, fig. 58. 
The colour is yellowish red, dull above, but shin- 
ing beneath. The thorax is short and transverse, 
the sides drawn out into a kind of spine. The ely- 
tra are nearly triangular, the basal angles advanced 
on each side of the thorax in the form of an acute 
point ; and there is an oval perforation observable 
near the base of each. It is found in the tropical 
parts of America.
