 sizes and shapes are observable: (1) a spot on the depression in 

 the centre of the upper surface of the head, (2) two large semi- 

 lunar patches opposing each other and three other small spots — 

 one central and two lateral — on the pronotum, (3) as a rule 

 the entire upper surface of the scutellum but sometimes with the 

 exception of a tiny area, (4) eight large patches on each elytron ; 

 described in detail below and including a small one just posterior 

 to the humeral angle, this spot being partly on the upper surface 

 and partly on the epipleuron, (5) on the underside, the lateral 

 pieces of the mesosternum, the whole of the metasternum and a 

 stripe on each abdominal sternite ; this stripe is often broken into

this gives rise to three longitudinal series of patches. The whole 

 body is moderately shiny and free from hairs. 



Head with a depression in the centre, in some cases this is more 

 pronounced than in others, and sometimes it takes a triangular 

 shape ; the clypeus is narrow, triangular and well marked off by 

 strongly impressed lines, the latter meeting a fine vertical median 

 impression ; the surface is scarcely punctate, in some specimens 

 more so than in others. First segment of antennse thickened and 

 rounded, second elongate, shorter than third but almost equal in 

 length to the fourth or fifth, the third is slender and is the longest 

 segment, from the sixth to the last the segments are thickened 

 and darkened in colour towards the end. Prothorax much 

 narrower than elytra, front margin widely emarginate. sides 

 almost straight, slightly narrowed towards the front, anterior
