Tribe VIII. OHRYSOMELINI. 



Oval, convex, rarely oblong beetles of moderate, rarely small 

 size, usually variegated in color. They have the antenna 1 of mod- 

 erate length, widely separated at base, the outer joints somewhat 

 enlarged; eyes feebly emarginate, not prominent; thorax with well- 

 defined side margins ; front coxa 1 transverse and widely separated ; 

 elytra with distinct epipleurse and covering the abdomen; third 

 tarsal joint entire (except in Gastroidea and Lin a}. Representa- 

 tives of nine of the 13 genera composing the tribe have been taken 

 in the State, while those of one other may occur. 



The only papers treating especially of the North American 

 genera comprising the tribe are as follows:

Allied Genera Inhabiting the IT. S.," in Proc. Phil. Acad. 



Nat. Sci., VIII, 1856, 29-39.

North America," in Journ. N. Y. Entom. Soc., IV, 1896,
