Cassida

1. Cassida bicornis. Bluish green except the black antennae whose radical joints are bronzed, the thorax bearing two or three small impressions and the punctured elytra each carrying a long obtuse spine projecting sidewise from the shoulder. It occurs in Cayenne, Surinam, and other parts of America.
2. Cassida scalaris. The thorax rounded in front, yellow with part of the middle red enclosing two yellow points, the scutellum red. The elytra are pale yellow with three broad longitudinal black stripes, the sutural one broken into square spots and the lateral ones each with a square piece separated near the apex, the under parts yellow; said to be found in Sumatra.
3. Cassida micans. The antennae yellow with the two last joints black, the thorax yellow and nearly transparent, the elytra yellowish brown on the disk with a stripe extending to each anterior angle and two others crossing the dilated margin from the rear. The margin and under parts of the body are pale yellow; it is found in Java.
4. Cassida echinata. A curious species with the thorax much dilated on each side into a thin foliaceous membrane dentate round the margin, a similar expanded dentate portion surrounding the elytra. The elytra have the anterior half green and the hinder part reddish brown, the under side dull yellowish red; like the preceding species it is a native of Java.
5. Cassida perforata. Yellowish red, dull above but shining beneath, the short transverse thorax with sides drawn out into a kind of spine, the nearly triangular elytra with basal angles advanced beside the thorax in an acute point. There is an oval perforation near the base of each elytron; it is found in the tropical parts of America.
6. Cassida luctuosa. Head and thorax black, the thorax short and ending in an acute point at each hinder angle, the elytra likewise black with all the outer edge, a small portion of the suture, and a short central line reddish. The under side and legs are also reddish; it is found at Surinam.
