The male of this species is characterized by the almost angular 

 dilation of the posterior border of the anterior femur, by the serrate 

 middle femur, and by the lateral lobes and apical emargination of 

 the seventh tergite. Segments 7 and 8 of the flagellum are distinctly 

 spinose, segments 9-11 are dilated and excavated below, and segment 

 12 is strongly curved. The genitalia are shown in Figure 209. In 

 both sexes the anterior metatarsus bears seven spines, and the second 

 abscissa of the cubitella is lacking. The wings of the female are 

 relatiAcl}^ shorter than is normal in this genus. 



The specimens of this species in the United States National Mu- 

 seum are all from Deesa, India. Handlirsch reports this species from 

 Mauritius and Ceylon; Cameron reports it from Barrackpore, Bom- 

 bay, and Gilgit.

This species stands very close to Bembix trepanda^ from which 

 species the male may be distinguished by the absence of an apical 

 emargination on the seventh tergite, by the fact that segments 7 and 

 8 of the flagellum are not distinctW spinose below, and by the different 

 form of the genital stipes. The female differs from the female of 

 trepaiula by having the sixth tergite black. A single female in the 

 United States National Museum, received in an exchange as a female 

 of this species, bears a pair of basal black spots on the clypeus. It 

 bears the label, " Sikhim, Coll. Bingham." The two males that I 

 have referred to this species are from Deesa, India.
