Chrysomela Wallacei.

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

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

 race modice convexo, disco tenuiter punctato, lateribus rotundatis 

 incrassatis, intra marginem longitudinaliter excavatis et ibi pro-

Hab. Mantchuria. 



Oblong and parallel in the male, 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; antennae 

 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 impunctato, lateribus rotundatis, a medio ad 

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

 magnis sparse impressis ; elytris ovatis, postice subattenuatis, 

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

 sequidistanter et remote positis in striis, striis uonnullis ponemedium 

 omnino deletis.
