NEW GENERA AND SPECIES OF HYMENOPTERA. 261 



This species will form a new section in Bingham's " B " and c, 

 defined by the metanotal area being punctured. 



Crabro agycus, sp. nov. 

 Black ; the base of the median segment with three areae, the 

 central being narrower than the others ; the scape of the antennae , the 

 mandibles above, a broad line on the pronotum, the scutellar tubercles, 

 a large mark on the sides of the scutellum at the base, broadest on the 

 outer side, and with a semicircular small incision in the middle, the 

 post-scutellum, a line on the first abdominal segment, narrowed in the 

 middle, a small mark on the second laterally, and large broad ones on 

 the third to fifth segments, the tubercles, a small mark behind them, 

 and a larger longer mark, narrowed below, behind that, lemon-yellow. 

 Legs yellow ; all the coxfe and trochanters, the basal half of the fore 

 femora above and the lower part, the greater part of the middle femora 

 below, the hinder, except on the top, the four hinder tibiae in front, 

 and at the top and bottom behind, black ; the tarsi infuscated towards 

 the apex. Wings hyaline, the stigma fuscous, the nervures darker. $ . 

 Length, 8 mm. 



Hah. Himalayas. 



Front and vertex smooth and shining ; the front covered with 

 golden pubescence ; the vertex sparsely pilose ; the face and clypeus 

 covered with silvery pubescence. Mandibles smooth and shining ; the 

 two apical teeth stout, clearly separated. Metanotal areae smooth ; the 

 central is of almost equal width ; the inner lateral become roundly 

 narrowed towards the apex ; the outer lateral of almost equal width ; 

 the sides of the apical slope are bordered by keels. Pleurae smooth and 

 shining ; the tubercles large, projecting. The mesopleural furrow is 

 obscurely crenulated. Pygidium keeled laterally, and bearing large 

 punctures. The hinder tibiae become gradually thicker towards the 

 apex, and bear some stout spines ; their metatarsus not thickened. 



This species may be known from the recorded Indian species 

 by the five clearly defined areas on the base of the median 

 segment. 



Bembex megadonta, sp. nov. 



^ . Black ; the apical two-thirds of the clypeus, labrum, man- 

 dibles, except at the apex, the outer eye-orbits narrowly, the apex of 

 the pronotum broadly, the edges of the propleurae all round, the lower 

 narrowly, the sides of the metanotum, the apical half of the meta- 

 pleurse, and the apices of the scutellum and post-scutellum, pale 

 yellow. Abdomen pale yellow ; a broad black band on the base of the 

 first segment, narrowed and roundly incised at the apex, a broad band 

 on its apex, roundly narrowed laterally, two spots broader than long 

 on the base of the second, an irregular band on its apex, a band on the 

 base of the third with two dilatations in the middle, a narrow band on 

 its apex, dilated in the centre; similar bands on the fourth segment, 

 the basal half of the fifth, the band with a shallow incision on the 

 apex, and the whole of the apical two segments, black ; the ventral 

 segments black, their sides at the apex irregularly marked with yellow. 

 Legs yellow, all the coxae, a broad line on the top of the first pair of
