556 INSECTA. 



EuMOLPUs, Kliig, Fab. 



Where the mandibles are of the ordinary size, and the second 

 joint of the antennse is shorter than the following one. 



E. vitis, Fab. J Panz., Faun. Insect. Germ., LXXXIX, 12. 

 Black, pubescent; elytra, base of the antennae, and the legs red- 

 dish-brown; very injurious to the Vine. 

 This subgenus, through the Colaspes, and by an almost insensible 

 transition, is connected with the genus 



Chrysomela, 



When the body is usually ovoid or nearly oval, and the head salient, 

 projecting, or simply inclined; where the antennae are simple, about 

 half the length of the body, and most frequently granose and insen- 

 sibly enlarged towards the extremity. 



Some, in which the body is always ovoid or oval and provided 

 with wings, and the palpi terminate in a point, approach the Eu- 

 molpi, and are distinguished from the other following Chrysomelinse 

 by their filiform antennae, which are longer than the half of the body, 

 and consist of elongated and almost cylindrical joints, the eleventh 

 or last of which is terminated by an appendix or false joint, the 

 length of which is almost equal to that of the half of the preceding 

 portion of that joint. Such are 



CoLASPis, Fab. 

 Where there is no sternal projection(l). 



PoDONTiA, Dalm. 



Where the mesosternum projects in a short and conical point, the 

 end of which is received into a posterior emargination of the prae- 

 sternum(2). 



The first and penultimate joint of the tarsi is very large and 

 strongly dilated; the second is small. The last joint of the maxillary 

 palpi is conical. The body is oblong, depressed, or but little ele- 

 vated, while in Colaspis it is generally short and very convex. 



In the following Chrysomelinae of the same tribe, the antennae are 

 shorter and composed of obconical joints, or are more or less almost 

 granose and gradually enlarge towards the extremity; the false joint 

 or appendage terminating the last is very short or indistinct.
