This prettj- insect ought to stand near C. grossa and its congeners. 



6. Chrysomela dngulata. 



C. elongato-ovata, convexa, nigTo-£euea, nitida, supra obscure cuprea ; 

 thorace lateribus incrassatis, intra marginem sulcatis et profunde punc- 

 tatis, disco tenuiter subcrebre pvuictato ; elytris fidvo-rufo mavginatis, 

 punctato-striatis, striis bifariam dispositis ; auteunarum articulo ultimo 

 penultimo fere duplo longiore, oblongo-ovato, apice angustato. — Long.

Elongate-ovate, convex, nigTo-jEueous or obsciu'e cupreous, nitidous ; 

 body above obscure cupreous. Head finely but distinctly punctm-ed, 

 puncturing scattered on the forehead, rather more crowded on the lower 

 portion of the face ; antennse nigro-ca?ruleous, slender, rather shorter 

 than half the body, their apical joint oblong-ovate, its apex subacumi- 

 nate; thi'ee basal joints more or less fulvous beneath. Thorax twice 

 broader than long ; sides nearly straight and parallel behind the middle, 

 rotundate-angustate in fi'ont, more quickly narrowed at the apex ; upper 

 surface with its lateral borders thickened, and bomided internally with 

 a broad shallow longitudinal depression, more distinct at the base, its 

 surface covered with large, deeply impressed, irregidarly confluent, 

 variolose punctui'es; disk, together with the thickened margin, sub- 

 remotely covered with distinct but fine pmactm'es. Scutellum smooth, 

 shining, semi-ovate. Elytra slightly broader than the thorax, five times 

 its length ; sides subparallel, their outer margin bordered with fulvo- 

 rufous : each elytron with eleven rows of distinct, deeply impressed 

 punctm'es; the first abbreviated; the second nmning parallel to the 

 suture ; the eleventh finer, and placed on the extreme edge of the rufous 

 border ; the eight others forming four double rows of punctures, which 

 are placed at nearly equal distances on the disk ; interspaces vagiiely 

 and distantly reticulate-strigose, minutely and subremotely punctured. 

 Beneath shining, distantly punctured ; legs covered with subremote 

 deep punctures. 



Hab. Northern India. 



Nearly allied to Chrysomela marginata, but easily separated from 

 that species by its larger size, finer punctation, and, above all, by the 

 different form and greater length of the terminal joint of its antenna), 

 which themselves are also more slender than in C. marginata. In 

 the present insect the last joint is more slender and nearly twice the 

 length of the penultimate, whilst in the other species it is broader, 

 shorter in relation to the penultimate, more regularly ovate, with its 

 upper edge towards the apex oblique.
