 Nomia {^Paranoinia) zebrata, sp. n. 



Black ; the head and thorax densely covered with longisli 

 white ))ubescence ; the apices of the second to sixth segments 

 banded with greenish blue and smooth and shining, the apex 

 of the first dull green ; the legs dark })iceous, the tibite and 

 hinder femora not dilated; the hair thick and ])ale ; the 

 wings hyaline, the nervures fuscous, the stigma darker. (J . 



Long. 7 mm. 



JIab. Barrackpore, Bengal (Rothney). 



Antennai black ; the scape covered with lontxish white 

 hairs. Head : the front, face, and clypeus thickly covered 

 with white pubescence, the upper two thirds of the clypeus 

 keeled in the middle ; the apex is depressed, smooth, and 

 transverse in the middle ; the punctuation towards the apex 

 runs into strias. Mandibles black, broadly piceous in the 

 middle ; their base is distinctly punctured. Mesonotum and 

 scutellum closely punctured ; the scutellum is broadly but 

 not deeply depressed in the middle, its apex is sparsely 

 covered with long black hair ; the postscutellura is thickly 

 covered with white pubescence. The basal area of the 

 median segment is bordered behind by stout transverse keels ; 

 the sides are irregularly reticulated. Pleurt^ thickly covered 

 with white hair, which is much longer on the metapieuraj. 

 The cox£e and trochanters are darker than the rest of the 

 legs; the hair on the underside of the tarsi is rufous; the 

 spurs are testaceous. Except on the apical bands, the abdo- 

 minal segments are closely but not strongly punctured. The 

 ventral surface is smooth, shining, and piceous in colour ; the 

 last segment is keeled in the middle, the keel becoming 

 stronger towards the aj)ex, which has a short narrow incision. 



This species comes close to JY. Frederici] the two may bo 

 separated thus: — 



The area on the median segment transversely striated at the 

 base ; the flagellum of the antennaa black ; the legs 

 piceous zebrata. 



The area on the median segment not transverst-ly striated at 

 the base ; the ilagellum of the antennas brownish ; the 

 legs black Frederici.
