SOME NEW GENEKA AND SPECIES OF HYMENOPTERA. 263 



of a thicker basal segment, and a very slender " seta," either 

 exarticulate, or partly or altogether divided into numerous seg- 

 ments. Tegula almost always present. Empodium coalesced 

 with the claws throughout a shorter distance, and at most 

 through two-thirds of the length of the claws ; free margin a 

 little emarginate or simple. Second pair of abdominal spiracles 

 dorsal, somewhat remote from the lateral margin.

SPHEGIDiE. 

 Ampulex longicollis, sp. nov. 

 CaBrulea, antennis pedibusque nigris, femoribus posticis dimidio 

 basali rufo ; alis fusco-violaceis. ? . Long. 16-18 mm. 



Hah. Khasia (coll. Piothney). 



Antenna black, sparsely covered with black hairs ; the third joint 

 twice the length of the fourth. Head dark purple, the cheeks and oral 

 regions of a brighter tint ; the front and vertex coarsely rugosely punc- 

 tured ; the former with a keel down the apical two-thirds. Clypeus 

 aciculated, stoutly keeled dowu the middle, and sparsely haired ; the 

 apex rounded ; the sides armed with an oblique longish tooth. Man- 

 dibles black, keeled down the middle and at the sides. The front and 

 vertex are sparsely haired. Thorax blue, mixed with purple and 

 green ; the median segment for the greater part indigo-blue. Pro- 

 thorax smooth, aciculated, and with a few scattered punctures ; its 

 base distinctly separated, and the apex is depressed ; the apical part 

 narrowed towards the apex and transverse at the base ; the prothorax 

 is if anything longer than the mesothorax, which bears large deep 

 scattered punctures, as do also the scutellum and post-scutellum ; 

 these are sparsely covered with long black hair. The central keel on 

 the median segment is straight, and reaches shortly beyond the 

 middle ; the second keel is of similar length ; the outer longer, 

 reaching to the apex ; the segment is stoutly transversely striated, 

 the strife becoming more curved and irregular at the apex of the keels ; 

 the middle part at the apex is smooth ; the apex of the segment is 

 perpendicular, and ends at the sides above in stout teeth. Mesopleurse 

 coarsely irregularly punctured ; the metapleurae with a longitudinal 

 keel below the keel which ends in the tooth ; the space between the 

 two bearing, near the middle and apex, some straight keels ; the base 

 below is aciculated, the rest reticulated. Mesonotum bearing large 

 deep round punctures ; its base smooth ; the middle furrow deep.
