Antenna) inserted on the sides of the clypeus, a little nearer 

 to the base than to the apex, shorter than the head, tho 

 flagclliim more than twice as long as the scape. Posterior 

 ocelli much nearer to each other than to the eyes. Pro- 

 notum very short, transverse, the angles acute ; mesonotum 

 opaque, the parapsidal I'urrows distinct, but very shallow ; 

 scutellum subopaque, with a transverse groove at the base ; 

 pk'urfe almost smooth. Median segment rather coarsely 

 reticulate, the enclosed area well marked, with two rather 

 low longitudinal carinas near the middle. Abdomen smooth 

 and shining. Second abscissa of the radius a little shorter 

 than the tirst, equal to the second transverse cul)ital nervure; 

 second cubital cell less than half as long again on the cubitus 

 as on the radius ; recurrent nervure received at a distance 

 before tlie apex of the first cubital cell equal to about half 

 the length of the first abscissa of the radius.

 {Turner) ; March. 



This species is nearest to A. approxiniatus in the sculj^ture, 

 but is a smaller species, with the head less massive, the 

 nervures darker, and the second cubital cell much longer.

$ . Nigra ; scapo tegulisque bruneo-testaceis ; prothorace rufo- 

 ferrugineo ; femoribus apice, tibiis basi, tarsisque luteis ; alia 

 hyalinis, venis pallidis, stigmate fusco. 



Loug. 3 mm. 



? . Head scarcely longer than the greatest breadth ; the 

 front obliquely striated, with a carina from the base of the 

 clypeus not quite reaching the anterior ocellus. Eyes 

 strongly divergent towards the cly])ens, not quite reaching 

 to the base of the mandibles, or to tiie posterior margin of 

 the head. Posterior ocelli as near to the eyes as to each 

 other; the carina round the eyes well marked. Antennae 

 inserted nearer to the eyes than to each other, a little longer 

 than the head, the scape about half as long as the flagellum. 

 Pronotum transverse, crcnulate, the anterior angles ])ointed ; 

 mesonotum granulate. Median segment very long, much 

 longer than broad, reticulate, the enclosed area triangular, 

 with a median longitudinal carina. Abdomen subpetiolate, 

 elongate, smooth and shining, the sixth segment without a 

 pygidial area. Second cubital cell rather more than half as 

 long on the radius as on the cubitus; the first transverse 

 cubital nervure a little longer than the second abscissa of the 

 radius, about equnl in length to the first abscissa of the 

 radius : stiuma about twice as long as tho greatest breadtli.
