It is singular that Cameron should describe this common 

 and wide-ranging East African species as new, without 

 any note of comparison. 



Cerceris vigilans, Sm., sub-sp. pei'vigilans sub-sp. n. 



9 . Differs from Indian specimens in having the postscutellum 

 yellow instead of black ; the enclosed area at the base of the median 

 segment is finely granulate instead of finely and closely punctured ; 

 the pygidial area is more strongly narrowed towards the apex ; 

 the petiole of the second cubital cell is a little longer ; and the 

 wings are sub-hyaline at the base, with a distinct fuscous apical 

 border. 



(J . The differences in the male are the same as in the female, but 

 the pygidial area is narrower throughout than in typical vigilans.

The differences seem to me to be too small to be of 

 full specific value, the most important being in the shape 

 of the pygidial area. The rather remarkable form of the 

 clypeus is identical. Yet vigilans is an Indian species, 

 not recorded from intermediate localities.
