LarricLx, Odynerus and Apidx^ from Barrachpore. 131 



Hah. Bareackpore {Rothney). 



Antennae black, tlie apical half of the flagellum brownish, black 

 above. The clypeus is strongly, regularly but not very closely, 

 punctured — the face is less strongly punctured — the front and vertex 

 are coarsely alutaceous ; the front has a narrow distinct keel which 

 extends from the ocelli to the base of the antennae ; the front, face and 

 clypeus are covered with wliite pubescence ; the vertex more sparsely 

 with longish pale hair. The reticulation on the mesonotum l^ecomes 

 stronger towards the apex ; the scutellum is less strongly reticulated 

 at the sides ; the post-scutellar region is thickly covered with white 

 hair. The apex of the pronotum is raised laterally at the base into 

 a sharp plate-like projection, which above is thickly covered witli 

 white pubescence. Mesopleura^ obscurely reticulated. The base of 

 the median segment is irregularly reticulated, the longitudinal .strias 

 are regular ; the transverse ones much more irregular and more or less 

 broken, the sides and the apical slope are thickly covered with white 

 pubescence, the hair on the sides is much longer than elsewhere. 

 The liair on the tibia? and tarsi are fulvous, on the femora, sparser, 

 longer and white, the hair is fringed ; the outer spur on the hinder 

 tibiae is armed with stout spines. "Wings clear hyaline, the stigma 

 and nervures testaceous, the first recurrent nervure is interstitial. 

 Abdomen smooth, shining, impunctate ; the base of the second segment 

 has a band of white, depressed pubescence at the base ; the other 

 segments are broadly, but not tliickly, fringed, with white pubescence 

 on the apex, the anal fimbra is rufous, the ventral surface is covered 

 rather thickly with long white soft hair. 



The hinder tibia; and tarsi are distinctly rufous, this being also the 

 case with the femora beneath ; the tegida? are rufo-piceous ; there are 

 no transverse furrows on tlie abdominal segments. 



Comes near to H. Hodomus, Yachal. 



HalictiLS Lcngalensis, n. s. 

 Long. 7 mm. 

 Hah. Barrackpore (Rothney). 



This species comes near to H. reyJonicus, but it wants 

 the blue tint on the head and thorax ; the base of the 

 median segment is strongly marked with stout twisted 

 keels, the clypeus is more strongly and distinctly punctured 

 all over, and there is a distinct transverse furrow on the 

 basal two abdominal segments. 



Antenna black, brownish beneath towards the apex. Front 

 closely and uniformly punctured, the vertex is less closely and
