and depths, sparser on the central area, closer, coarser and 

 confluent at the sides, not reaching the lateral margin, thus leaving 

 a longitudinal impunctate strip which may be slightly convex. 

 Scutellum small, ovate, smooth, impunctate. Elytra very slightly 

 broader at the base than the prothorax, irregularly punctate, the 

 punctures having a tendency to form rows as is usual in the genus, 

 the interspaces more minutely punctate. Underside sparsely and 

 finely punctate.

Bengal : Berhampore (Brit. Mus.) ; Patna, ii. 1906, on wheat ; 

 Chapra (Mackenzie); Pusa, Bihar, 3. v. 1907 (Lefroy); these 

 records are from 3 examples in the Pusa Collection. United 

 Provinces: W. Almora, Kumaon, 2 specimens (H. Q. Champion). 



Type in the British Museum. Described from ten examples. 



This may be a variety of Cli. inconstans, Wied., but as the ten 

 examples are constant in the general scheme of their coloration, 

 I propose to treat it as a separate species until evidence to the 

 contrary is forthcoming. 



18. Chrysolina karachia, sp. nov. 



Body elongate. Colour blue-black with brassy sheen: underside 

 brown, but not the legs, which share the same colour as the 

 upper side. 



Head broad, with a few fine scattered punctures, more numerous 

 in some specimens than in others ; clypeus delimited by a well- 

 impressed, transverse, curved line, longitudinal median impression 

 more or less faint. Antennae nearly half the length of the body ; 

 first segment large, thickened, second small, nearly half the 

 length of the third, fourth and fifth each shorter than third, sixth 

 slightly shorter than fifth, the next five segments thickened, 

 opaque and pubescent. Prothorax quadrate, slightly broader 

 than long, front margin emarginate, sides straight, narrowed 

 towards the front, basal margin sinuate, anterior angles acute 

 and rounded, posterior almost right angles ; upper surface convex 

 in the central area and with fine, scattered punctures, lateral areas 

 longitudinally and very shallowly depressed, the depression 

 containing coarse and confluent punctures ; at each side, between 

 this rough area and the extreme edge, is a narrow smooth strip 

 which appears convex when the insect is viewed sideways. 

 Scutellum triangular, smooth, impunctate, with apex acute. 

 Elytra broader at the base than the prothorax; each elytron is 

 confusedly punctate, the punctures having a tendency to arrange 

 themselves in longitudinal rows, this partial regularity being more 

 marked on the inner half than on the outer, so that a short 

 scutellar row, a sutural row and one or two irregular discal rows 

 can be recognized ; the whole surface is uniformly and more or 

 less closely covered with almost the same kind of punctures, but 

 there may be an exception here and there ; no tendency to
