ihe sides very closely and finely longitudinally strigose, the lateral 

 margins strongly curved, the hind angles obliterated, and the base 

 gently but abruptly emarginate in the middle. The scutellum is 

 moderately long and not very blunt, and the elytra are strongly 

 puDctate-striate, with the sides deeply sinuated and the apical 

 angles moderately sharp. The ])i/[/kUwn and the sides of the 

 inetasternum are rugose, and the abdomen bears only a few coarse 

 punctures. The sternal process is slightly produced and rounded 

 in front, the front tibia is strongly and sharply tridentate, and 

 the hind tibia has a rather long, but not close, fringe of pale 

 yellow hairs. 



The sexes are similar, but the male has the spurs of the hind 

 tibise shorter and sharper than the female.

Type not traced; those of prusina and sanguinalis in the 

 British Museum. 



The typical form, described above, is very abundant and widely 

 distributed, but remarkable varieties more or less localized occur 

 in India and the southern part of the enormous area of which the 

 species is a native. 



The best marked Indian varieties are the following: — 



Var. a. 



Green, with a blood-red patch at each shoulder and the outer 

 apical part of each elytron, and the usual white markings. 

 Sikkim : Darjiling. 



Var. sanguinalis, Hope. 



Like the preceding, but with the whole external margins of the 

 elytra broadly red.
