CHBYSOLINA. 



41 



elytron deep purple, violet or steel-blue, the shades varying in 

 intensity; antennae brown beneath, their upper side sharing the 

 general colour of the insect, the five apical segments infused witli 

 piceous. 



Head smooth, shining, gently convex in the middle, sparsely 

 and finely punctate ; clypeus depressed, median longitudinal line 

 faintly impressed. Antennas long, more than half the length of 

 the body ; first segment large, thickened, second small, shorter 

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

 next five segments thickened, rounded, opaque and pubescent. 

 Prothorax broader than long, front margin emarginate, sides 

 straight, slightly widened anteriorly, basal margin sinuate, 

 anterior angles broadly rounded, posterior more or less nearly 

 equal to right angles ; upper surface gently convex from side to 

 side, more or less closely punctate with finer and coarser punctures, 

 on the lateral areas the punctures are coarser and more or less 

 confluent; the pronotum, viewed sideways, shows a longitudinal, 

 more or less convex, smooth strip with much finer punctures, 

 and along the extreme margin is a row of punctures. Scutellum 

 small, triangular, smooth, im punctate. Elytra slightly broader 

 than prothorax, punctate-striate, the punctures being irregularly 

 arranged, the tendency to doubling of the rows not recognizable, 

 the interspaces more finely punctate; owing to the presence of 

 the interspatial punctures the seriate punctures cannot be 

 accurately counted. Underside: abdominal sternites more or less 

 closely punctate. 



Length, 6 mm. ; breadth, 3 mm.

Body oblong, convex. Colour cupreous, at the point of 

 articulation of the appendages red-brown, antennas and legs 

 blackish -aeneous. 



Head: clypeus distinctly punctate, A-shaped mark deeply 

 impressed, remaining portion of the surface of the head convex 

 and scarcely punctate. Antennae scarcely half the length of the 

 body, robust, third segment longer than fourth, second almost 

 equal to fourth. Prothorax twice broader than long, sides slightly 

 rounded and arapliate, narrowed in front ; there are a few deep, 

 scattered punctures, without any arrangement, on the central 

 area, each lateral area being closely covered with deep, coarse and 

 confluent punctures, giving it a very rugose appearance; the 

 extreme marginal areas are longitudinally slightly convex and
