4th abdominal segment being much thicker and distinctly interrupted in the 

 middle and by that on the 5th being much wider, it clearly extending beyond the 

 middle of the segment, it being also not so distinctly narrowed in the middle. 



Nomia abuensis, sp. nov. 



Black, the pubescence cinereous, almost white, the apices of the abdominal 

 segments with white pubescent bands, the basal metanotal area irregularly 

 striated, the centre with a y\ — shaped area with a keel down the centre ; wings 

 almost hyaline, highly iridescent, the stigma dark testaceous, the nervures dark- 

 er coloured ; tegulee blackish on inner half, pale testaceous on outer. 9- 



Length 6 mm. 



Abu (Nurse). 



Head closely, strongly punctured, the punctures stronger on the sides of the 

 vertex than elsewhere. Face broadly raised in the centre. Mesonotum and 

 scutellum closely and much more finely punctured than the head ; the prono- 

 tum densely covered at the base with white pubescence ; it is raised at the base, 

 the basal slope being bare ; the pubescence extends along the top to the tegulae. 

 Post-scutellum densely covered with white pubescence. Metanotum wrinkled ; 

 it has a somewhat steep slope ; it is weakly keeled down the centre and on the 

 outer edges. Pleura? alutaceous. Flagellum brownish red below. Apical joints 

 of tarsi rufous. 2nd cubital cellule not much longer along the transverse 

 cubitals than it is along the radius : 2nd abscissa of radius about one-fourth 

 shorter than the 3rd. 



Nomia collina. sp. nov. 



Length 7 mm. 9 • 

 Mount Abu. 



This species is very close to N. abuensis ; the differences can be best shown in 

 synoptical form. 



Base of metanotum with a crennlated area ; 2nd cubital cellule 

 wide, 3rd abscissa of radius about one fourth longer than 2nd, 



the 2nd transverse cubital nervure straight Abuensis. 



Base of metanotum without a crenulated area ; 2nd cubital 

 cellule narrow, 3rd abscissa of radius 4 times longer than 2nd ; 



the 2nd transverse cubital nervure curved Collina. 



Metanotum opaque, alutaceous, neither the centre nor the sides are keeled ; 

 the apex of the basal area is prolonged in the centre into a sharp point ; head, 

 pro-and mesothorax closely, not very strongly punctured ; the puncturation on 

 the face and clypeus runs into obscure reticulations ; there is an impressed line 

 on the centre of the front, running into the top of the face. Tegulse pale 

 testaceous, darker coloured on the innerside. Abdomen fully longer than the 

 head and thorax united : the basal segment is covered at the base with white 

 pubescences ; the apices of the segments with bands of white depressed pile. 

 Tips of tarsi rufous. Middle of face not distinctly raised. 



Coelioxys latus, sp. nov. 

 Short, wide compared with the length, the clypeus, the greater part of the 

 face and front, outer orbits, collar, spot in centre of mesonotum at the base.
