534 Major C. G. Nurse on new 



^ . Similar, but the clypeus has a deep semicircuhir exca- 

 vation anteriorly, the apices of the antennae are yellowish, 

 and the ground-colour of the head and thorax is Wack ; the 

 tibife and tarsi are yellow, and in some specimens there are 

 sublateral yellow spots on the median segment. 



Long, (to end of second abdominal segment) 9-10 millim. 



Hah. Mount Abu ; very common. 



Kext to 0. giittatus. The male bears a strong superficial 

 resemblance to a large edition of 0. ovali's ; but, apart from 

 size, the present species may be distinguished from (J. ovalis 

 by its broader clypeus, with a much deeper emar,oitu\tiou at 

 apex, and by the scutellum, which is only yellow at the 

 lateral angles. 



Odynerus segregatus, sp. n. 



? . Eather stoutly built ; vertex of head, thorax, and 

 second and following abdominal segments somewhat coarsely 

 punctured, clypeus and front finely and shallowly, first abdo- 

 minal segment sparsely, and shallowly punctured, sides of 

 median segment rugose ; clypeus subpyriform, its apex in- 

 cised, the portion ot the front between tlie bases of antennae 

 raised, with an impressed median line posteriorly; median 

 segment vertical, concave, its sides truncate or produced 

 backwards; first abdominal segment nearly twice as broad as 

 long, its apex as wide as second segment. Black ; the man- 

 dibles at base, clypeus and front, except a spot behind the 

 base of each antenna, and a line along the outer orbits, a 

 broad band on the pronotum, a spot on the episternura, the 

 lateral angles of the scutellum, the postscutellum, and apical 

 bands on first, second, and third abdominal segments, yellow ; 

 the band on the first segment is incised in the middle and 

 slightly wiilened at the sides, that on the second segment is 

 bisinuate, widened at the sides, and continued below, where 

 it covers nearly the whole of the segment, that on the third 

 segment is bisinuate above and below ; base of first abdo- 

 minal segment red ; legs red, variegated with yellow. "Wings 

 hyaline, nervures black, teguliB yellow. 



Long, (to end of second abdominal segment) 9 millim. 



IJab. Deesa ; a single specimen. 



This species would come into Bingham's key next to 

 O.jistulosus. 



Prosoiiis Txashmlrensis, sp. n. 



? . Clypeus and front sparsely, vertex and thorax minutely, 

 abdtmen shining, yery minutely punctured; enclosed space
