 cuprea, nitida, subtus obscurior, purpureo tincta ; antennis dimidio 

 corporis longioribus, nigris, articuHs basalibus subtus piceis ; tho- 

 race modice convexo, disco tenuiter punctato, lateribus rotundatis 

 incrassatis, intra marginem longitudinaUter excavatis et ibi pro- 

 funde varioloso-punctatis ; elytris maris parallelis, foem. postice

Hab. Mantchuria. 



Oblong and parallel in the mahy ovate and enlarged towards 

 the posterior extremity in the female^ convex^ shining cupreous, 

 more obscure beneath, with a purple tinge. Head punctured ; 

 epistome depressed, bounded above by an acutely-angled grooved 

 line, either end of which is suddenly rounded, and from its apex a 

 faint longitudinal groove runs upwards to the vertex; antennse 

 rather slender, nearly filiform, rather longer in the male than half 

 the body. Thorax twice as broad as long ; apex broadly excavated; 

 sides straight and nearly parallel, rounded and narrowed before 

 the middle ; upper surface moderately convex ; disk subremotely 

 but distinctly punctured ; sides thickened, longitudinally exca- 

 vated immediately within the thickened portion, the excavation 

 itself being broad and deep on its hinder half, shallower and less 

 distinct in front, its surface covered with subremote punctures, 

 larger and deeper than those of the disk. Elytra much more 

 closely and coarsely punctured than the thorax, the punctures 

 arranged in numerous irregular ill-defined rows. The sides of 

 the thorax vary somewhat in form in different individuals ; rarely 

 (in the male) they are rotundate-ampliate from the base; in the 

 female they are always less straight behind the middle than in 

 the other sex. 



Chrysomela Krishnu. 



C. anguste oblongo-ovata, convexa, cuprea, nitida ; thorace modice 

 convexo, disco fere im punctato, lateribus rotundatis, a medio ad 

 basin angustatis, valde incrassatis, intus foveolatis, hie illic punctis 

 raagnis sparse impressis ; elytris ovatis, postice subattenuatis, 

 profunde gemellato-striatis, punctis purpureo-cupreis magnis in- 

 eequidistanter et remote positis in striis, striis uonnuUis ponemedium 

 omnino deletis.
