NEW GENUS AND SOME NE W SPECIES OF HYMENOPTERA. 135 



and apical half of propleurae, a mark wider than long, triangularly incised on 

 basal half on mesonotum, scutellum, 2 spots on apex of post-scutellum, a large, 

 triangular mark on mesopleurae, nearer the base than apex, a broad band. on the 

 apex of 1st abandominal segment, squarely, broadly dilated laterally and with 

 an incision at the base, the narrowed middle part slightly dilated in the middle, 

 broad bands, dilated laterally, except the last, and narrower bands on ventral 

 segments 2-6, bright yellow. Legs similarly coloured, the trochanters, base of 

 femora above and a broad line on the outer side of the hind tibia?, black. Wings 

 clearly hyaline throughout, the nervures black, the stigma brown ; the 2nd abs- 

 cissa of radius fully one-fourth longer than the 3rd, the 2nd and 3rd abscissae 

 of cubitus about equal in length ; the 1st recurrent nervure is received at the 

 base of the apical fourth, the 2nd at the apex of the basal 3rd. Antennas stout, 

 not tapering towards the apex, as long as the head, thorax and basal segment of 

 abdomen united ; black, except for a small yellow spot on apex of scape. $ . 

 Length 12-14 mm. 



Quetta. May to July ; very common. 



Temples roundly narrowed. Basal third of abdominal petiole greatly 

 narrowed as compared with the enlarged apex, which is longish cup-shaped ; 

 the 2nd to 5th segments are of equal width, the apical slightly narrowed. 

 The hair on the metathorax is longer and denser than elsewhere ; it is opaque, 

 alutaceous. The black bands on 2nd and 3rd segments are of equal width, the 

 central are rounded, narrowed laterally. Apical slope of metanotum transverse. 

 Clypeus broad, rather strongly punctured, the apex with a slight, shallow 

 incision, the sides at apex oblique. 



Smith describes a P. orientalis from Baluchistan ; taking Bingham's descrip- 

 tion of it (Hym. of Brit. India, I, 69) it should be separated from my species 

 as follows : 



" Punctures light and inconspicuous," " antennas very long 

 and filiform;" pleurae immaculate, " centre of scutellum 

 orange yellow; " nervures dark testaceous ... ... ... crientalis. 



Punctures strong and conspicuous, antennas not very long, 

 stout, pleuras with a large triangular mark, nervures 



black, scutellum entirely yellow baluchistanensis. 



Plesia subpetiolatus, sp. nov. 

 Black, mandibles except at apex, a narrow line on apex of pronotum, lines, 

 dilated laterally, on the apices of the basal 4 abdominal segments, 3 broad lines 

 on the 5th, 3 shorter ones on the 6th, the apex of femora, the tibiae, except 

 broadly below and the tarsi, pale yellow ; wings clear hyaline, the stigma brown, 

 the nervures darker, almost black, the 2nd and 3rd abscissae of radius almos 

 equal in length, the 2nd abscissa of cubitus less than one-fourth longer than 

 the 3rd ; the 1st recurrent nervure received shortly, but distinctly beyond the 

 middle, the 2nd near the apex of the basal third of the cellule. $ 

 Length 9 mm. 

 Quetta ; common from May to August.
