CASSIDA ECHINATA. 



PLATE XXVIII. FIG. 4. 



Fabr. Syst. Ekuth Olivier, vi. No. 97, pi. 5, fig. 86. 



This curious species has 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. 

 Fabr. Syst. Entom. Olivier , vi. No. 97, pi. 4, fig. 68. 



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.
