132 INSECTA, 
Povontia, Dalm. 
Where the mesosternum projects in a short and conical point, the 
end of which is received into a posterior emargination of the preester- 
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 Chrysomeline of the same tribe, the antenne 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. 
Puyxiocuaris, Dalm., 
Where there is no mesosternal projection +. 
Dorypuora, Illiq., 
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 antenne, 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. Asin Phyllocharis, there is no mesosternal 
projection, but the joints of the antennz 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, Oliv.—Nortocie4, Marsh, 
Of which all the species are exclusively proper to New Hovlland, is

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

§ Chrysomela rotundata, Dej., and another very analogous but striped species. I 
have received from Dr. Leach a Chrysomela allied to the Doryphore, in the male of 
which the antenne present but eight joints, the two last forming a club. It con- 
stitutes his genus Apamea. The Chrysomela badia of Germar appears to form 
another.
