202 I September, 



spine-like process, maiiilibles entire, pointed, anfcennaj with the scape nearly twice as 

 wide at tlie apex as the 2nd joint, which is slightly wider and shorter than the 3rd, 

 from the 3rd to the 7th they are subequal in length and much longer than wide, the 

 remainder are shorter, especially the penultimate, and the apical joint is subconical ; 

 mesonotum punctured, much as the vertex of the head. Wings nearly hyaline 

 with a dusky apical band, 2nd submarginal very small, petiolated, in the specimen 

 before me nearly equilateral, the sides and petiole subequsil in length, 3rd submar- 

 ginal longer than wide, much narrowed at the top, the recurrent nervures ai'e 

 received in the 1st and 2nd submarginals, mesopleurse and sternum rather largely 

 and clearly punctured, propodeum clothed with white hairs and transversely wrinkled 

 at the sides, its basal area irregularly and somewhat diagonally rugose, with a slight 

 central impression, in which is a fine narrow keel at the base. Legs very sparingly 

 clothed with a fine whitish pubescence. Abdomen scarcely shining, its basal seg- 

 ment closely and finely punctured, the intervals on the disc about twice as wide as 

 the individual punctures, puncturation of the 2nd closer and finer than the 1st, 

 that of the 3rd and following almost imperceptible. Long., 4 mm. 



Very distinct from the other described species by the black postscutellum, and 

 the smaller area of the petiolated submarginal cell, and in the slenderer antennae, 

 and from compeditus, also, in the smaller and more triangular basal area of the 

 propodeum.

Black, base of the mandibles, palpi, the tubercles and tegulse, tibiae, and tarsi 

 flavous, the former with a large black streak on the side towards the body. Wings 

 nearly hyaline, nervures dark brown, apex of abdomen testaceous. Head dull, micro- 

 scopically rugulose, very finely punctured, remotely so on the vertex, very densely 

 and closely on the face, an impressed line runs from the central ocellus to between 

 the insertion of the antennae, face below the anfennsG clothed with bright silvery 

 hairs. Antennae with the joints of the flagellum from the 2nd to the apex sub- 

 equal, longer than wide, clothed with very fine short greyish pubescence, visible 

 only under a strong lens, the apex of each joint rather prominent on its lower 

 margin, so as to give it almost the effect of being spinoscly produced ; mesonotum 

 slightly shining, microscopically rugulose, and finely punctured, 2nd submarginal 

 cell very narrowly trapezoidal, its apical margin about half the width of the basal, 

 propodeum very rugose, its brow with a distinct, though irregular, transvere carina j
