78 COLEOPTERA. 



of considerable size. The elytra are of great breadth, half as broad 

 again as the thorax. C. Grossus, Linn., a native of Guiana, is black, 

 with red elytra, marked with depressed black dots, and towards 

 the edge with black reticulated markings. 



The European species of the typical genus Cassida, Linn., are 

 rather numerous. They are of moderate size, and most of them 

 are green, but others are black, or red, spotted with black. C. 

 Vittata, Vill., is green above, with a golden band on each of the 

 elytra ; the under surface is black. It is about a quarter of an inch 

 in length, and is not an uncommon species. 



FAMILY IX. Languriidce. 



Antennae rather short, inserted before the eyes, eleven-jointed, 

 the four or five last joints forming a large oblong compressed 

 club ; body long, narrowed behind. 



These insects are entirely exotic, and most of the species are 

 found in the East Indies. The great majority of the species 

 belong to the typical genus Languria, Latr. ; they measure about 

 one-third of an inch in length. One of the best known species is 

 L. Bicolor, Fabr., common in the Southern United States; it is 

 black, with the face and sides of the thorax red. 



Some of the East Indian species are considerably larger ; thus 

 Callilanguria Luzonica, Crotch, from the Philippines, is nearly an 

 inch in length. The head is black, the thorax red, and the elytra 

 green. 



FAMILY X. Erotylidce. 



Body variable in shape, oblong, oval, elliptical, or hemispherical ; 

 head small, partly concealed by the thorax ; antennae ten- or eleven- 

 jointed, the last two, three, or four joints forming a compressed 

 club ; elytra oval, elliptical, covering the abdomen ; legs sometimes 

 five-jointed. 



An interesting and rather extensive family, which, however, is 

 poorly represented in Europe by a few small species, which are 

 generally found in fungi. 



Triplax Russica, Linn., is a reddish-yellow oval beetle, with 

 the antennae, scutellum, elytra, and pectus black ; it is a quarter of 

 an inch in length, and is not an uncommon species. 



Erotylus Histrio, Fabr., is a handsome Brazilian species ; it is 

 black, and the elytra are irregularly banded with yellow, with a 

 red spot on each shoulder, and another near the tip of each elytron.
