CHRYSOMELIN.E. 



double rows oP well-impressed punctures, a short scutellar row of 

 a few punctures and a single row placed near the suture ; the punc- 

 tures very distantly placed and at unequal distances in the rows ; 

 those of the third double row are quite irregularly distributed, 

 with scarcely any arrangement in pairs ; the extreme lateral margin 

 is also impressed with a row of deep punctures. There is con- 

 siderable variation in the puncturing and arrangement of the rows, 

 also in the depth of impression ; sometimes the punctures are 

 comparatively more crowded near the base and more distant on the 

 hinder half of the disc. In one specimen in the British Museum 

 Baly attached a separate (unpublished) name, Ck. dormari, owing 

 to the insect having the punctures in a more or less obsolescent 

 condition, but I think it is merely an example of Ch. Jcrishnu: it 

 is, like the rest, from South India. The punctures themselves are 

 deeply coloured in the centre. Underside and legs greenish, 

 scarcely punctured ; prosternum without a longitudinal furrow. 

 Length, 8g-9 mm. 



South India. : Ootacamund. Also one example from the Nilgiri 

 Hills (Pusa Coll.). 



Types of both JcrisJinu and semifalua in the British Museum ; 

 having examined both, I am convinced that semifulva is a synonym 

 of Jcrishnu. 



10. Chrysolina ceylonica, sp. nov. 



Body oblong, broader posteriorly, convex. Colour brilliant 

 metallic blue, sometimes with bright cupreous sheen on the elytra ; 

 underside less brilliant than upper side. 



Head broad, sparsely and finely punctate ; clypeus depressed, 

 separated from the rest of the surface by an impressed curved 

 line which is interrupted in the middle by a slightly elevated 

 longitudinal area along the median line. Antennas moderately 

 stout, passing a little distance beyond the base of the pronotum, 

 the five basal segments shining, the next six segments more 

 thickened and opaque; first segment thickened, second small, 

 nearly half the length of the third, fourth and fifth each shorter 

 than third, each of the following segments becoming gradually 

 slightly larger. Prothoracc broader than long, sides straight 

 towards the base, rounded anteriorly, front margin widely 

 emarginate, basal margin almost straight from the middle to the 

 side, anterior angles rounded, posterior almost right angles ; 

 surface gently convex from side to side, with a few scattered and 

 deeply impressed punctures in the middle area, the lateral 

 longitudinal area longitudinally convex, bounded inwardly by a 

 longitudinal depression in which are coarse and confluent 

 punctures. ScuteUum more or less triangular, with base straight 

 and apex rounded, the surface smooth and im punctate. Elytra 

 broader at base than prothorax ; each elytron has the following 

 rows of punctures : a short scutellar row of a few punctures only, 

 the next row along the suture, then four pairs of rows ; punctures
