AND Si'EClES OF GALERUClNiE.

break with the hinder margin of the antepectus, or trae 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 presternum to 

 meet in the median line, as in Galeruca and llenlppus. 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 

 appeudiculated claws, and from the relative length of the elytral 

 epipleurse. 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 the presternum lobed ; in the rest the lobe is obsolete. 



Grenus Charidea. 



Corpus elongatura, modice convexum. Caput exsertum, oculis rotun- 

 datis ; encarpis elongatis, pyriformibus ; antennis filiformibus ; palpis 

 maxillaribus articulo ultimo ovato. Thorax transversus, convexus, 

 disco calloso. /ScM^e/Zwrn trigonatum. Elytra parallela, modice trans- 

 versim convexa, punctato-sti iata, interspatiis interdum costatis ; 

 epipleuris fere ad apicem extensis. Pedes rohiisti, simplices ; tibiis 

 apice mutieis ; metatarsi articulo basali ad duos sequentes fere tequi- 

 lougo. Prosternum inter coxas distiucte visum, ante basin loba- 

 tum ; acetabulis anticis integris aut paullo apertis. 



Type Charidea punctato-striata, Motscb. 



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 (Enidea, but is separated 

 from that genus by the punctate-striate and costate elytra, and 

 by the non-incrassate 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 iu placing them 

 under the same generic head.

In this species the anterior acetabula are slightly open.
