There appears to be a close resemblance between this 

 insect and the variety of^the female of 0. bellatulus, Sauss., 

 mentioned in Saussure's Etud. Fam. Vespid. iii. Masar. 1856, 

 p. 243, from the Gambia. 



0. icellmani may be distinguished from this variety by the 

 second joint of the flagdlum, which is considerably longer 

 than in O. bellatulus, Sauss. ; in addition to this, the 

 second abscissa on the radial cell is half as long as the third, 

 whereas the second cubital cell in 0. bellatulus is sub- 

 petiolate.
