Ampulex nitidicollis, sp. n. 



$ . Viridis; mandibulis, flagello articulis 3-11 secundoque dimidio 

 apicali, tarsisque, articulo basali excepto, nigris ; alia fusco- 

 byalinis, fusco obscure bivittatis. 



Long. 19 mm. 



? . Clypeus broadly rounded anteriorly, strongly longitu- 

 dinally carinate in the middle, without lateral teeth. Eyes 

 strongly convergent towards the vertex, where they are sepa- 

 rated by a distance scarcely exceeding three-quarters of the 

 length of the second joint of the flagellum. Head not pro- 

 duced behind the eyes and not much narrowed posteriorly, 

 very minutely and closely punctured, with a few larger but 

 shallow scattered punctures ; the two frontal carinse parallel 

 and not nearly reaching the level of the anterior ocellus. 

 Pronotum fully as long as its median breadth, narrowed 

 anteriorly, without strife, with a few scattered punctures, 

 depressed and subconcave anteriorly, raised and subtubercu- 

 late in the middle posteriorly, without a distinct median 

 sulcus. Mesonotum and scutellum very sparsely punctured. 

 Median segment nearly as long as its median breadth, strongly 

 transversely striated, the strise closer and finer between the 

 second and third lateral carinse than elsewhere, the second 

 carina at least half as far again from the median at the base 

 as from the third, the three median carinse not extending to 

 the apex and leaving a well-defined apical area ; the teeth at 

 the apical angles of the segment broad and not very long, 

 slightly curved, and not very acute at the apex. Abdomen 

 almost smooth ; second tergite fully as long as its greatest 

 breadth, the sides only slightly convex ; segments 4-6 rather 

 strongly compressed laterally. Fourth joint of the hind tarsi 

 less than half as long as the fifth and much shorter than the 

 third ; hind tibiae very sparsely punctured on the outer side. 

 Fourth abscissa of the radius scarcely half as long as the 

 second transverse cubital nervure; first transverse cubital 

 nervure present, but not quite as strong as the second.
