82 HYMENOPTERA ACULEATA. 



pubescence up to tbe ocelli, the eyes are closer together on 

 the vertex, the distance between them not being longer 

 than the first and second joints of the flagellum together ; 

 the mesonotnm is more strongly punctui'ed and its sides 

 more or less clothed with golden pubescence ; anterior 

 tibiae and femora pale in front ; it is also rather larger than 

 pectinijjes ; the ?, which I have never seen, is said to differ 

 from that of pectinipes in having the anterior tibiae pale in 

 front, and the apical dorsal valve shorter, not being more 

 than once and a half as long as wide. 



L. 9-10 mm.
