68 HTMENOPTEEA. 



the second cubital cellule at the top is half the length, of the space bounded by the 

 recurrent nervines. 



Not unlike A. apicipennis, but smaller, and easily known from it by the thorax and 

 head being densely clothed with, long hair ; the much more strongly rugose pleura? and 

 median segment ; the shorter abdomen ; and the pygidial area much more clearly raised 

 at the edges, and furrowed on the inner side of them,, the edges, moreover, being spinose 

 throughout. The first cubital cellule is clearly longer than the second. 



b. Abdomen red.

Heaxif almost transverse, distinctly broader than the thorax, rather strongly, but 

 sparsely, punctured on the top ; the face and vertex closely and rugosely punctured, 

 almost opaque ; clypeus shining, sparsely punctured. Eyes slightly converging towards 

 the top r ocelli in a triangle. Clypeus projecting in the middle, and with three short, 

 stout teeth there, broadly and roundly carinate down the centre. Mandibles broadly 

 red before the apex. Antennae stout; the third joint one fourth longer than the 

 succeeding. Pro- and mesonotum shining, covered with, large scattered punctures, the 

 mesonotum with two indistinct fine furrows in the centre towards the apex, the space 

 bounded by these being depressed ;, pleurae rugose, opaque ; sternum shining, sparsely 

 punctmred. Median segment opaque,, finely rugose, the apex oblique and coarsely 

 transversely rugose. Abdomen a little shorter than the thorax, shining, sparsely haired. 

 Pygidial area shining, finely aciculate, indistinctly margined laterally, the apex rounded. 

 Appendicular cellule longer than the radial, which is not much longer than the 

 second and third cubital cellules united; the second cubital cellule at the top and 

 bottom is wider than the third,, and at the top is narrower than the space bounded 

 by the recurrent nervures, which are received near the apical and basal fourth of the 

 cellule ; the second transverse cubital nervure is straight, the first is slightly bent, the 

 third is broadly curved outwardly. Legs : the coxae and femora bearing black hair ; 

 the tibiae and tarsi moderately spinose..
