of some species of Chri/soviela, ^c. 191 



coarsely punctured, the puncturing on the inner side 

 arranged in ill-defined irregular strite. 



Scarcely more than half the size of C. grossa, to which 

 insect it is nearly allied. It may be known by the shape 

 of the thorax, the sides of Avhicli in grossa are rounded 

 and converging from base to apex ; in the present species 

 they are straight and parallel behind the middle. 



Chrysomela rufo-marginata. 



Ovata, convexa, subtus cum antennis nigra, cupreo vix 

 tincta ; supra cuprea ; thorace nitido, minute, ad latera 

 magis fortiter punctato, utrinque basi intra marginem late- 

 ralem longitudinaliter foveolato ; elytris fortiter et regula- 

 liter punctato-striatis ; ffineo micantibus, limbo exteriori 

 sordide rufo. 



Long. 3.^ — 4 lin. 



Hah. — Mesopotamia. 



Head very minutely bu.t not closely punctured ; clypeus 

 transverse, depressed, more distinctly punctured than the 

 upper face ; antennfe rather slender, not half the body 

 in length, black, the basal joints obscure rufo-piceous. 

 Thorax rather more than twice as broad as long ; sides 

 rounded and converging from base to apex, the anterior 

 angles subacute ; above convex, very finely and rather 

 distantly punctured, the puncturing rather closer and 

 more distinct at the extreme base, a longitudinal space 

 between the disk and outer margin coarsely punctured ; 

 lateral margin not thickened, separated from the disk at 

 the base by a longitudinal fovea and again at the apex by 

 a faint, ill-defined depression. Elytra rather broader than 

 the thorax, convex, the highest part of the convexity being 

 behind their middle ; each elytron with eleven strongly- 

 punctured strije, the first abbreviated, the punctures on 

 each stria placed at irregular intervals, the third and 

 fourth, fifth and sixth and seventh and eighth rows obso- 

 letely approximating in pairs ; interspaces plane, sparingly 

 impressed with minute punctures ; outer limb obscure 

 rufous, the rufous colour entirely covering the outer inter- 

 space. About the same size and somewhat similar in 

 form to Ch. lamina, elytra punctured as in that insect ; 

 it may be easily separated by the different sha])e of the 

 thorax and by the difference in its lateral margination.
