MONOGRAPH OF THE WASPS OF BPTTISH INDIA. 515 



Habitat — Karachi ( Comber ). October. 



With this species I associate, with some doubt a male taken at Karachi 

 m considerable numbers by Mr. Comber. It is yellow, with the vertex, 

 cheeks, mesonotum, middle of the median segment and the base of all the 

 abdominal segments narrowly black. Clypeus convex, more than half as 

 broad again as long, narrowly truncate at the apex. Fifth and sixth ven- 

 tral segments produced into a short spine on each side at the apical 

 angles. Pygidial area about half as long again as the greatest breadth, 

 broadly rounded at the apex, the sides parallel. Length 8mm. 



The female somewhat resembles C. anne.va Kohl., but has the clypeus 

 and pygidial area much broader. 



Cerceris bolanica sp. n. 



§ , Nigra ; clypeo, fronte, scapo, pronoto utrinque, tegulis, postscutello, 

 segmento abdominali secundo basi, tertio quintoque totis, quarto apice, 

 pedibusque flavis ; alis hyalinis, apice leviter infumatis, venis fuscis ; 

 clypeo apice angustato, emarginato ; mesopleuris hand dentatis ; segmento 

 ventrali secundo area basali elevata nulla ; segmento mediano area basali 

 punctata. 4. 



S . Femini3e similis ; clypeo latitudine latiore, apice rotundato. 



Long. S , 7 mm. ; c5', 6 mm. 



2 . Middle lobe of the clypeus as long as the greatest breadth, much 

 narrowed towards the apex, the apical margin slightly porrect and very 

 shallowly emarginate. Antennae inserted a little nearer to the base of 

 the clypeus than to the anterior ocellus, the second joint of the flagellum 

 only very slightly longer than the third. Inner margins of the eyes 

 parallel ; posterior ocelli nearly twice as far from the eyes as from each 

 other. Mesopleuree without tubercles ; first abdominal segment nearly 

 half as long again as broad, second ventral segment without a raised area 

 at the base ; pygidial area elongate ovate. First recurrent nervure 

 received at one quarter from the base of the second cubital cell. Rather 

 deeply punctured ; the enclosed area at the base of the median segment 

 punctured with a longitudinal median groove ; postscutellum smooth. 



■ S • Clypeus longer than broad, rounded at the apex ; pygidial area 

 about half as long again as broad ; first recurrent nervure received at 

 two-fifths from the base of the second cubital cell. 



In both sexes the third ventral segment is yellow, and the flagellum 

 beneath reddish. 



Habitat — Quetta {Nurse). July. 



This is near C. rubida Jur., but in that species the antennse are inserted 

 nearer to the base of the clypeus, and the sculpture is much coarser. The 

 present species may be identical with C. vagans Rad., but the description
