 segmentisque dorsalibus 1-3 fascia apicali pallida aureo-pubes- 

 oeutibus : area pygidiali fuseo-ferruginec)-setoso ; alls pallidissime 

 flavo-hyalinis, venis ferrugineis.

$ . Clypeus shining on the apical margin and subtruncate.* 

 Second and third joints of the flagellum subequal ; eyes

 colour of the wings and legs, in the shorter tarsal comb, in 

 the much sparser pubescence, and in the shorter median

 truncate at the apex as in deceptor, Turn.
