 spicuous round marks on each side of abdominal segments 

 1 and 2, coxae, femora, and the anterior tibiae, on the outside, 

 yellow. 



Mandibles, apical area of clypeus, scape and segments 

 2, 3, 4 of antennae, tegulae, postorbits below, median seg- 

 ment laterally, marks on each side of abdominal segments 

 1 and 2 (joining the yellow spots), two conspicuous marks 

 on second abdominal segment on ventral surface, apical 

 margin of abdominal segment 4, abdominal segments 5 and 

 6 totally ferrugineous. Tarsi, intermediate and posterior 

 femora ferrugineous. Abdominal segments 2 and 3, with a 

 narrow apical margin above, whitish. Wings golden hyaline, 

 fuscous in radial cell. 



Clypeus rounded at the base, rather longer than broad, 

 narrowly produced to form two blunt, short teeth at apex. 

 Scutellum flat, divided from the postscutellum by a con-

There appears to be a close resemblance between this 

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

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

 p. 243, from the Gambia. 



O. wellmani may be distinguished from this variety by the 

 second joint of the flagellum, 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 O. bellatulus is sub- 

 petiolate.
