HYMENOPTERA. 285 



the maxillary palpi obsolete, or reduced to a minute tubercle ; the" 

 superior wings having one marginal and three submarginal cells, 

 the former longer than the three latter united, rounded at its 

 apex ; the first and second submarginal cells subquadrate, ob- 

 lique ; the third submarginal much narrowed towards the mar- 

 ginal, receiving the second recurrent nervure in the middle, the 

 first recurrent nervure uniting with the second transverse cubital 

 nervure ; posterior legs elongate and densely pubescent in both 

 sexes. In some instances the first recurrent nervure is received 

 a little within the third submarginal cell, but the typical form 

 appears to unite it to the transverse nervure.

The labial palpi composed of two joints, the basal joint half 

 as long again as the mentum, the second joint twice its length, 

 its apex terminating in a sharp spine or point; the maxillary 

 palpi composed of one joint situated on a tubercle at the side of 

 the maxilla?. The superior wings having one marginal and three 

 submarginal cells, the former being longer than the three latter 

 united. 



St. Fargeau gives four joints to the labial palpi, which after an 

 examination of several specimens cannot be detected.
