NEW SPECIES OF INDIAN HYMENOPTERA. 17 



with a few scattered punctures. Black ; the abdomen shining ; the 

 mandibles, except their tips, the scape and the first one or two joints 

 of the flagellum of antenna?, the pronotum, tubercles, scutellum, post- 

 scutellum, a spot on the coxa? below (frequently obsolete), all the 

 femora, tibia?, and tarsi, broad bands on the second, fourth, and fifth 

 abdominal segments, and sometimes also on the third segment bright 

 yellow ; the tarsi at apex more or less inclining to ferruginous ; cly- 

 peus wifch-short, thick, silvery pubescence, remainder of head, thorax, 

 and apical abdominal segments with short, sparse, greyish pile ; wings 

 subhyaline, nervures and tegulae testaceous, cubital nervure received 

 into the radial cell just before its middle. 



$ Similar ; antenna? 12-jointed as in the 9, but with joints 2-6 of 

 the flagellum very much thickened, being about three times as wide as 

 the scape ; anterior tarsi slightly thickened, whitish ; scutellum and 

 postscutellum black, not yellow ; abdomen with yellow bands on second 

 to sixth segments, apical abdominal segment when extended smooth, 

 emarginate at base, with stiff greyish hairs at apex. 



Long. 6-S mm. 



Habitant : Quetta ; common. 



This species belongs to the Thyreopus group, and having no enclosed 

 space at base of median segment, it is not very near to any of the In- 

 dian species. It makes its nest in hollow reed-stems, and stores 

 common house flies for its progeny. I saw a $ go into a reed-stem, 

 which I then cut off, and bred several specimens of both sexes from it. 



Crabro prosopiformis, n. sp. 



9 Smooth and shining, with a few scattered punctures on the 



head and mesonotum ; eyes at vertex more than twice their width apart 



near base of antenna? ; facetting of eyes coarser near inner margin 



below than elsewhere ; mandibles not notched below, their apices 



simple ; clypeus with the anterior margin produced and rounded in 



the middle ; antenna? with the joints of flagellum subequal, not 



thickened ; posterior ocelli much further apart from one another than 



from inner margin of eyes ; cheeks strongly developed, nearly as w^ide 



as eyes ; pronotum narrow, notched, below the level of mesonotum ; 



median segment with a narrow triangular space at base depressed and 



longitudinally striate, its apex produced into a median furrow, into 



which two lateral furrows join ; abdomen slightly longer than thorax, not 



petiolate, the first segment only slightly longer than the second ; pygi-
