AMERICAN HYMENOrTERA. 243 



Wings ample, two marginal and four subuiarginal cells, second and 

 third each receiving a recurrent nervure, the second small, rather quad- 

 rate, the third rather long , lanceolate cell with oblique cross line; un- 

 der wings with two middle cells. 



Aritennpc 10-articulate, short, a little thickened toward the end, arti- 

 culations rather indistinct, third joint largest, the apical joint rather 

 obtuse, with an obscure suture. 



//r'(7r(f transverse, labrum generally rounded in front; mandibles bi-

The larv<i3 of A. spimo'um of Europe is said to be exceedingly de-

 They come forth in a constant succession, from August till near No-
