HYMENOPTEllOUS FAMILY STEPHANID^. 735 



This species much resembles S. rafo-femoratus Szepl., also 

 from the same locality, but difiei'S in the relative length of the 

 basal joints of the antennae, sculpture and length of petiole, and 

 the strongly trans-striate hind coxfe. 



Cameron considers it to be near his Megischus violaceipennis 

 from New Britain, in which the sculpture of the body tends to 

 be reticulate. 



Mr. C. T, Brues found in the Museum of Hax'vard College 

 4 $ $ , 2 cJ J , from Auki, Tulagi, Fulakora, and Malaili. The 

 larger females, 26-31 mm., have the femoral teeth more strongly 

 developed than in the smaller individuals of 21-23 mm. The 

 males measure from 20-21 mm.
