llymenoptera 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. Pygidium 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 foveas on the median segment are large ; the 

 metapleurse are shining and only slightly punctured compared 

 with the mesopleurse; the propleurae are stoutly obliquely 

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

 maculata, Cam., but is abundantly distinct otherwise. 



Cerceris latibalteata, sp. n. 



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

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

 mandibles, a line on the hinder part of the pronotum, the 

 scutellum, postscutellum, the greater part of the third abdo- 

 minal segment, and a line on the apex of the fifth yellow ; 

 the wings fuscous, the radial and the front of the cubital 

 cellules smoky ; the stigma and nervures black. ? . 



Long. 7 mm. 



Antennas black ; the flageilum broadly brownish beneath. 

 Head entirely black ; above the antennas 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 scutellums are 

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

 indistinctly finely punctured, and has a narrow furrow down 

 the centre. Propleurae obscurely striated ; the mesopleune 

 punctured, and with a wide and deep longitudinal furrow in 

 the centre. Metapleurce shining, obsoletely punctured, and 

 obscurely striated under the wings. Legs black ; the front 

 tibiae anteriorly and the tarsi yellowish. The greater part 

 of the third and the apex of the fifth segments are reddish ; 

 the pygidium irregularly shagreened and punctured.
