A]S T D SPECIES OF GALERUCIN.ZE.

break with the hinder margin of the antepectus, or true hinder 
border of the under surface of the thorax. 
In this group the acetabula are sometimes closed by the pro- 
longation of the epimera across the base of the prosternum to 
meet in the median line, as in G-aleruca and Menippus. On the 
presence or absence of the subbasal lobe, I would divide the 
family into two primary groups, taking as secondary ones those 
derived from the spines at the apices of the tibiae, the bifid or 
appendiculated claws, and from the relative length of the elytra! 
epipleurae. My object in making these remarks is to justify the 
use of characters drawn from the form of this basal lobe as a 
diagnostic character in the new genera described in the present 
paper. 
Of the genera mentioned or described below, the first five have 
the prosternum lobed ; in the rest the lobe is obsolete. 
Genus Charidea. 
Corpus elongation, modice convexum. Caput exsertum, oculis rotun- 
datis ; encarpis elongatis, pyriformibus ; antennis filiformibus ; palpis 
maxillaribus articulo ultimo ovato. Thorax transversus, convexus, 
disco calloso. Scutellum trigonatum. Elytra parallela, modice trans- 
versim convexa, punctato-stiiata, interspatiis interdum costatis ; 
epipleuris fere ad apicem extensis. Pedes robusti, simplices ; tibiis 
apice muticis ; metatarsi articulo basali ad duos sequentes fere sequi- 
longo. Prosternum inter coxas distincte visum, ante basin loba- 
tum ; acetabulis anticis integris aut paullo apertis. 
Type Charidea p unctato-stricit a, Motsch. 
This genus may be known from Galerucella , in which the 
typical species was placed by Motschulsky, by the lobed base of 
the prosternum ; it ought to stand near CEnidea, but is separated 
from that genus by the punctate-striate and costate elytra, and 
by the non-iucrassate palpi. 
Although the two species placed by me in this genus differ iu 
one having closed, the other open acetabula, they agree so entirely 
in all other characters that I have no hesitation in placing them 
under the same generic head.

In this species the anterior acetabula are slightly open.
