FAMILY LT1I. CHRYS0MEL1D.TS. 



11th one-half longer than 10th and acuminate at apex; in female joints 4 

 to 10 are equal, shorter than third and slender. Thorax one-half wider 

 than long, base scarcely broader than apex, margins finely serrate ; surface 

 rather sparsely but deeply and coarsely punctate. Elytra distinctly wider 

 than thorax, umbone prominent; disk with nine rows of coarse, closely 

 placed punctures, those of the inner rows confused at base ; intervals slightly 

 convex. Length 2-3 mm. 



Throughout the State; frequent on sumac and Hercules' club. 

 May 20-July 7.

 1889, 249. 



Elongate, parallel. Pale reddish-yellow, shining. Thorax one-half wider 

 than long, widest in front of middle, sides curved, slightly oblique in front of 

 base, margins entire ; disk convex, rather coarsely, sparsely and irregularly 

 punctate. Elytra wider at base than thorax, umbone distinct; disk with 

 feebly impressed rows of rather distant moderate punctures ; intervals flat, 

 smooth. Length 1.5-2 mm. 



Floyd County ; scarce. June 28. Known heretofore only from 

 Kansas and Texas. 



LXVIII. Epitrtx Fond. 1859. (Gr., "upon + hair.'') 



Very small convex species, differing from Crepidodera in the 

 upper surface bearing short, semi erect hairs, sparsely placed over 

 the thorax and arranged in a single row on each interval of the 

 elytra. The head has an oblique ridge each side, extending from 

 the end of the frontal carina to the eye and limited above by an im- 

 pressed line, the two forming together a broad V. The front angles 

 of the thorax are obliquely truncate with a small tooth behind the 

 truncation. Five species are known from the State, while another 

 may occur.

 very feeble. 2251. fi-scela. 



IjJ). Thorax not densely punctate, the punctures well separated, 

 c. Antebasal impression well marked.

 dd. Elytral stria?, especially those nearest the suture, very feeble, the 

 punctures round, not crowded. 2252. ce/cumeris.
