CHRYSOLINA.

median line absent. Antennae short, passing a little distance 

 beyond the base of the pronoturn ; first segment thickened, second 

 small, shorter than third, fourth and fifth each shorter than 

 third, fifth slightly shorter than fourth, the sixth to the 

 eleventh more thickened and rounded, opaque and pubescent. 

 Prothorax broader than long, front margin widely emarginate, 

 sides straight towards the base, rounded anteriorly, basal margin 

 almost straight and slanting towards the front from the middle 

 to the side, anterior angles rounded, posterior almost right angles ; 

 surface gently convex in the middle, covered with punctures of 

 various sizes and of varying degrees of fineness and coarseness ; 

 each side longitudinally convex from the base to the front, the 

 convex area being bounded internally by an equally long de- 

 pression containing coarse and confluent punctures. Scutellum 

 triangular, smooth and impurictate. Elytra broader at the base 

 than the prothorax, more or less parallel-sided ; irregularly punctate, 

 for although the tendency towards the formation of rows and the 

 usual scheme of a short scutellar, a sutural and four double rows 

 can be recognized, yet the confused punctures on the interspaces 

 render the regularity of the rows indistinct ; the punctures are 

 deeper and larger in some parts and smaller in others. Underside 

 very sparsely covered with short silvery hairs, each rising from a 

 puncture. 



Length, 10-11 mm.; breadth, 6-7 mm. 



Bengal: Berhampore ; Pusa, Bihar, 8. iv. 1894 (Pusa Coll.); 

 Chapra (Mackenzie, Pusa Coll.); Cuttack, Orissa, xi. 1905 (0. 8. 

 Misra, Pusa Coll.). Central Provinces: Balaghat, iii. 1907 (Pusa 

 Coll.). Ch. orientalis, Wied., was originally described from 

 Bengal ; the locality given by Gemminger and Harold for coerulipes 

 is " India or." 



Type probably in Copenhagen.

Body mirrowly oblong, moderately convex. Colour bright 

 cupreous or dark bronze, in some cases blue, antennas black, 

 head, scutellum and legs obscure aeneous. 



Head irregularly and moderately closely punctate, vertex with 

 a central longitudinal impression, clypeus separated by a deep 

 triangular impression. Antennas almost half the length of the 

 body : basal segment thickened, second short, third longer than 

 fourth, fourth and fifth equal in length, the five apical segments 

 slightly thickened and opaque, the last segment pointed. Prothorax 

 two and a half times as broad as long, the sides gently rounded 

 and narrowed anteriorly, anterior margin broadly concave, basal
