132 INSECTA. 



PoDONTiA, Dalm. 



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

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

 num *. 



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 elevated, 

 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. 



The maxillary palpi of some are thicker, and truncated at the ex- 

 tremity. 



Of these there are some in which the two last joints of those palpi 

 are united and form a truncated club ; the last is shorter than the pen- 

 ultimate, and is either transversal or in the form of a very short 

 and truncated cone. 



Phvllocharis, Dalm., 

 Where there is no mesosternal projection f. 

 DORYPHORA, Illig., 



Where the mesosternum, on the contrary, advances in a point, or in 

 the manner of a horn. The species of this subgenus are proper to 

 South America \; those of the preceding one inhabit New Holland 

 and the Island of Java. These, of which there are but few, differ 

 from the preceding in their more elongated and much less elevated 

 body, and in their antennae, the first joints of which are proportion- 

 ally shorter, thicker, and more rounded at the extremity ; the second 

 is almost globular and scarcely shorter than the third. 



Two species are found in Spain, which should form another sub- 

 genus — Cyrtonus, Dalm. As in Phyllocharis, there is no mesosternal 

 projection, but the joints of the antennae are proportionally longer 

 and more obconical; the body is more convex, and the thorax higher 

 transversely, and pulviniform, or rounded in the middle, whilst its 

 surface is plane or on a level in the preceding subgenera §. 



Another subgenus, 



Paropsis, OHv. — NoTOCLEA, Marsh, 

 Of which all the species are exclusively proper to New Holland, is

 Fab. ; Oliv. Col., V, 91, iv. 42.

 Nov., Germar. 



§ Chrysomela rotundafa, Dej., and another very analogous but striped species. I 

 have received from Dr. Leach a Chrysomela allied to the Doryphorae, in the male of 

 •which the antennae present but eight joints, the two last forming a club. It con- 

 stitutes his genus Apameea. The Chrysomela badia of Germar appears to form 

 another.
