one is convex. On the pronotum two stripes, an elongate 

 central spot and a spot on the middle of the sides touching 

 the margins are bronze black, and these markings are more or 

 less united along the margins of the thorax. The scutellum 

 and the sutural and lateral margins of the elytra are 

 blackish, the latter with a bronze hue, and an indistinct 

 iufuscate stripe runs from the shoulders backwards. The 

 punctuation is strong , somewhat finer but closer set on the 

 elytra than on the head and pronotum. The under surface 

 is bronze coloured and , as well as the legs , covered with a 

 scale-bearing punctuation. Besides the apical tooth , the fore- 

 tibiae have on their outer margin three sharp teeth which 

 become larger towards the end of the tibiae; the middle- and 

 hind tibiae are armed beyond the middle with a distinct tooth.
