HYMEXOPTERA AND VESPIDJ,. 61 



is impiinctate ; the lower part of the front in the middle is 

 almost smooth, and with an oval fovea in the middle. The 

 triangular depression on the apex of the clypeus longer than 

 it is wide at the apex, which is deeply depressed. Raised 

 apical part of pronotum wider than long, narrowed towards 

 the base, which is transverse ; it is strongly, but not closely 

 punctured and has a long deep furrow on the basal slope. 

 Mesonotum smooth, with some scattered punctures along the 

 outer edges. Lateral apical edges of the metanotum with a 

 short bluntly rounded tooth, the central longitudinal keel is 

 short and has 4, more or less regular keels on either side, 

 the central apical part is irregularly keeled, longitudinally in 

 the centre, transversely on the sides ; the 2"'* and 3''* keels 

 are regular and form a rounded curve at the apex ; the space 

 enclosed by them is smooth, except for some broken keels on 

 the edges ; the outer area3 are closely, strongly transversely 

 striated. Propleurse almost impunctate ; the apex with some 

 keels ; the meso- and metapleurtç strongly, but not closely 

 punctured. First abdominal segment with the basal third nar- 

 rowed into a clearly separated petiole ; the 2'"' is twice as 

 long as it is wide at the apex. Claws stoutly toothed near 

 the middle. 



Allied to A. latifrons Kohl and A. hrevicornis Cam. 



Ampulex micado sp. nov. 



Length 24 mm. ç.

Very similar — almost identical — in colouration with 

 A. javana here described, having also the some alar neuration, 

 but is a larger insect, and may be known by the narrowed 

 base of abdominal petiole being smaller ; the metanotum is 

 more strongly and regularly striated all over, the space between 

 keels 2 and 3, instead of being smooth, is closely striated all over.
