off laterally from its apex to tlie sides of the segment; the 

 central area is bordered by a larger, broader one, slightly 

 narrowed towards the apex and shorter than the central ; the 

 outerside of the metanotum. is bordered by a keel. Areolet 

 4-angled, not much narrowed in front ; the 2'"' transverse cubi- 

 tal nervure is thickened in front. 



This is probably a variable species as regards the quantity 

 of black and rufous colour on the head. There seems to be 

 also some difference in the keels on the median segment as 

 regards their stoutness. The head may be almost all black.
