and thorax thickly covered with long black hair. Basal segment 

 of abdomen large, the apical part more than half the length of the 

 2nd, which is about one-third longer than its width at the apex ; 

 it does not project much in the middle ; below its base projects 

 straight down from the first, somewhat as \wA. cognata., Kohl, and 

 A. latifronft. Cf. Kohl's figures pi. xii, f. M and 43, Ann. K.K. 

 Hof Mus. viii. The 2nd cubital cellule is clearly shortei- than 

 the length of the 2nd transverse cul)ital nervure. Fourth tarsal 

 joint not much shorter than the 3rd, largely dilated towards the 

 apex. 



Comes near to A. cyanura. Kohl, in Kohl's system. 



Ampulex spiloptera sp. nov. 

 Violaceous, slightly tinged with blue : the centre of mesono- 

 tum, scutellum and the 3rd and following segments of the 

 abdomen black, the mandibles and the antennal scape, except above, 

 rufous ; the 4 front tarsi testaceous, the posterior fuscous ; wings 

 hyaline, a fuscous cloud along the transverse median and transverse 

 basal nervures, the radial cellule and a broad cloud of almost its 

 width extending from it to the opposite side of the wings and the 

 apex of the hind wings dark fuscous; legs, except the tarsi, black. 

 Flagellum of antenna? black. Female. 

 Length 15 mm. 



Third transverse cubital nervure received two-thirds of the 

 length of the transverse cubital nervure from the apex of the 

 radius, as in A. laevigata Kohl. Cf. Kohl. Annal. K.K. 

 Hof mus VIII. Taf. XI; f. il5. 2nd cubital cellule in front less 

 than the length of the transverse cubital nervui-es ; somewhat 

 wider behind than in front ; 2nd recurrent nervure received at 

 the apex of the basal fourth of the cellule. Head closely and 

 strongly punctured ; the temples roundly narrowed behind. 

 Frontal keels stout, commencing shortly behind the middle, 

 parallel, not converging, straight. Hind ocelli separated by the 

 length of the 4th antennal joint from the eyes. Apex of clypeua 

 with a stent, longish, straight tooth on either side of the apex ; 

 outside this and cleai'ly separated is a short, broader oblique one. 

 Pronotum clearly longer than its width at the apex ; its base with
