the metasternal process is triangular at tlie base, obscurely 

 kfcled in the niitldle ; the apex is ilcpres.seil broadly in the 

 iniilillc. Legs black, the tibiie anl tarsi thickly covered with 

 glistening silvery-white hair ; the tibial spines white ; the 

 apices of the tarsal joints are rufous. Wings fuscous-viola- 

 ceous, the hinder pair only slightly paler in tint than the 

 anterior; the nervurcs are fuscous; the second cubital cellule 

 is distinctly shoiter than the third ; all the transverse cubital 

 norvures are roundly curved. Abdomen shining, sparsely 

 punctured, covered with I )ng white hair; the narrowed base 

 of the petiole is depressed in the mid lie abave ; the underside 

 is finely rugose and is furrowed down the centre. 



Comes nearest to M. fuscipennis^ but is abundantly distinct. 

 Characteristic is the almost impunctate mesonotum, which is, 

 according to Hinghani, more closidy and coarsely punctured 

 than the head in AL/uscipennis, but not according to Smith. 



Pompilidae.

Head alutaceous, below the antennaj thickly covered with 

 silvery pubescence. Eyes slightly converging at the top. 

 Clypeus roundly convex ; its apex clearly separated, smooth, 

 shining, glabrous, roundly, broadly incised, obliquely depressed. 

 Mandibles at the base thickly covered with depressed silvery 

 pubescence ; tlie underside at the base pale yellow ; before 

 the apex they are ferruginous ; the palpi black at the base ; the 

 apical joints pale ; the hair-bundle on the maxilla ferruginous. 

 Thorax alutaceous, pruinose ; the median segment sparsely 

 covered with fuscous hair. Wings clear hyaline; the stigma 

 black ; the nervures slightly paler; the first cubital cellule at 

 the top is very slightly longer than the second ; the trans- 

 verse cubital nervures are curved ; the first recurrent nervure 

 is received shortly before the middle; the second at the apex 

 of the basal third of the cellule. Legs black, pruinose ; the 

 anterior tibiaj and base of tarsi rufo-testaceous in front. 

 Abdomen pruinose. 



A distinct species. The genus Agenia^ as defined by Kohl, 

 has not been hitherto recorded from India. Tlie females are 

 easily separated from Pseudagenia by the maxilla having at 

 the base a bunch of long stiff hair ; but I am very much in
