132 Mr. R. E. Turner on Fossorial Ili/menoptera. 



bidentate at the apex. Antemife inserted as far from each 

 other as from the eyes, shorter than the head, the flagellum 

 a little more than twice as long as the scape. Eyes elongate- 

 ovate, not quite reaching the base of the mandibles, distinctly 

 divergent towards the clypeus, the carina round the margin 

 of the eyes rather indistinct. Posterior ocelli farther from 

 the eyes than from each other, and about twice as far from 

 the posterior margin of the head as from the eyes. Pronotum 

 short, transverse, the anterior murgin raised, the angles 

 sharj)ly pointed ; the tubercles of the prothorax reaching the 

 tegula3. Mesonotum opaque, closely aiul microscopically 

 punctured ; scutelhim subopaque, with a transverse groove 

 at the base. Dorsal surface of the median segment almost 

 entirely occupied by the enclosed area, which is strongly 

 reticulate, with two or three distinct longitudinal carinse, 

 the segment abruptly truncate posteriorly, the surface of the 

 truncation opaque, with a longitudinal carina near the apex. 

 Abdomen subpetiolate, fusiform, smooth and shining; tiie 

 sixth dorsal segment finely punctured, without a pygidial 

 area. Second cubital cell twice as long on the cubitus as 

 on the I'adius ; first abscissa of the radius a little longer than 

 the second ; recurrent nervure received by the first cubital 

 cell at a distance before the apex equal to the length of the 

 second abscissa of the radius ; stigma more than twice as 

 long as the greatest breadth.

Differs from A. reticulatus^ Turn., conspicuously in the 

 sculpture of the mesonotum, in the much longer head, tiie 

 shape of the second cubital cell, and in the finer sculpture 

 of the head and median segment. From qtieenslatidensis, 

 Turn., it differs markedly in the sculpture of the head, the 

 greater length of the head behind the eyes, and in the much 

 larger second cubital cell. The legs in this genus are un- 

 armed as in Spilomena, from which it difEers in the structure 

 of the pronotum.

5 . Nigra ; mandibulis, antennis, tegulis pedibusque testaceis ; 



alia hyalinis, venis fusco-ferrugineis. 

 Long. 3 mm. 



$ . Head a little longer than the greatest breadth, opaque 

 and almost smootii, the orbital carina3 developed on the outer 

 margin of the eye only ; the frontal carina almost obsolete 

 and not reaching the anterior ocellus. Eyes diverging to- 

 wards the clypeus, almost touching the base of the mandibles.
