Ilymenoptera from Northern India. 293 



the postscutellum reddish. The area on the median segment 

 is closely and uniformly punctured ; the rest of the segment 

 more strongly and deeply punctured all over. The segment 

 is more thickly and uniformly covered with fuscous pubes- 

 cence than the rest of the thorax. Abdomen closely punc- 

 tured ; the base of the first segment broadly, a small mark 

 in the centre of the second segment on the apex, the apical 

 two thirds or so of the third, and the apices of the three fol- 

 lowing segments narrowly red. Pygidiura coarsely, but not 

 very closely, punctured. There is an elongated mark on the 

 sides of the second ventral segment and a small one on the 

 sides of the fifth. 



The wings have a distinct violaceous tinge and are highly 

 iridescent. The fovese on the median segment are large ; the 

 metapleurae are shining and only slightly punctured compared 

 with the mesopleurse ; the propleuras are stoutlv obliquely 

 striated. In coloration the species agrees closely with C. bi~ 

 maculata, Cam., but is abundantly distinct otherwise. 



Cerceris Jatibalteata, sp. n. 



Black ; a broad line, obliquely narrowed above, on the 

 lower inner orbits, the antcnnal keel, the basal half of the

Antennae black ; the flagellum broadly brownish beneath. 

 Head entirely black ; above the antennae closely punctured ; 

 the apex of the clypeus projects broadly, is transverse, and is 

 more shining than the face. The thorax is not strongly or 

 very distinctly punctured ; an irregular line on the apex of 

 the pronotum, the base of the tegulae, and the scutelluras are 

 yellow. The area on the median segment is shining, is 

 indistinctly finely punctured, and has a narrow farrow down 

 the centre. Propleurae obscurely striated ; the mesopleurte 

 punctured, and with a wide and deep longitudinal furrow in 

 the centre. Metapleurce shining, obsoletely punctured, and
