and two transverse sinuate bands on the same colour, one, the 

 broadest, at about the median part, the other in the posterioi- 

 decUvity ; legs flavescent. Length 4J^ mm.; width 1^ mm. 

 Hab. Natal (D'Urban). 



It is probable that the prevalence of the yellow tint in the elytra 

 where the greenish tinge is reduced to transverse bands will be found 

 to vary much.

General characters of Bemhidium, but the anterior tibiae are 

 obliquely truncate at apex, and in the elytra the sutural stria is 

 recurved in the posterior part of the disk, instead of being connected 

 with the marginal stria. 



Tachys is represented in Europe, and Northern America.
