the metasternal process is triangular at the base, obscurely 

 keeled in the middle; the apex is depressed broadlj in the 

 middle. Legs black, the tibise ard 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 nervures are fuscous; the second cubital cellule 

 is distinctly shorter than the third ; all the transverse cubital 

 nervures are roundly curved. Abdomen shining, sparsely 

 punctured, covered with V)\\^ white iiair ; the narrowed base 

 of the petiole is depressed in the mid lie above ; 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 mesonotuin, which is, 

 according to Bingham, more clostdy and coarsely punctured 

 than the head in M.fuscipennis, but not according to Smith. 



Pompilidae. 



Agenia diana, sp, n. 



Nigra, basi mandibularum alba ; apice clypei inciao ; alis hyaliiiia, 



nervis stigmateque nigris. 2 . 

 Long. 11 mm, 



Hab. Khasia (Coll. Rotkney). 



Head alutaceous, below the antennae 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 ; the 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. 

 Thoi-ax 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 tibia 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 Lidia. The females are 

 easily separated from Pseudagenia by the maxilla having at 

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