in the $ nearly the same relative length and with joints 

 io — 13 hollowed beneath. There is a longitudinal keel on 

 the mesosternum, and there are two perpendicular and one 

 wider and shorter oblique furrows on the mesopleurse. The 

 first and second transverse cubital nervures are curved ; the 

 second cubital cellule at the top is somewhat less than the 

 space bounded by the two recurrent nervures. In the hind 

 wings the anal nervure is received shortly behind the origin 

 of the cubital nervure. The head and thorax bear scattered 

 punctures, those on the head being finer than those on the 

 thorax. The basal area of the median segment is clearly 

 limited by a crenulated furrow ; it is broader than long ; has 

 two central keels, united by transverse bars ; and there 

 are five stout keels on either side of these. The apex of 

 the median segment is hollowed in the centre, and trans- 

 versely striolated. The basal area varies from black to red. 

 The petiole is moderately broad at the base, and becomes 

 gradually broader towards the apex. Fore tarsi stoutly 

 spined.

 I suspect that this is only a variety of Orientalis ; but in- 

 asmuch as Smith's description gives no information as to 

 what group G. pictus belongs, this can only be decided by 

 an examination of the type.
