 yond stigmal vein, but at a point half way between stigmal 

 and apex; fringes not nearly as wide as wings, but only about 

 half width; club not terminating in several short spicules, but 

 in a long stout spine ; f unicle globular, club shorter, 1 wider 

 than long. Mandibles bidentate, club distinctly jointed. 



Roma, October 6, 1911. Formerly identified as americana. 



Oligosita longfellowi, new species. 



Wings deeply infuscated at basal third (out to middle of 

 marginal vein), widest across at that point. Like biclavata, 

 but fringes very long, exceeding wing-width ; color not intense 

 lemon, but pale yellow, the metathorax and hind coxse dusky ; 

 tarsal of hind legs (1 and 2) very elongate (moderately long 

 in other), setse from marginal vein much exceeding segment's 

 length. Characterized by the narrowing fore wings.

 of abdomen except at margin, and several abbreviated stripes 

 across distad of this, orange. Eight lines distinct discal cilia ; 

 club nippleless, funicle distinctly longer than wide, smaller 

 than the large pedicel. Knees not pale. Hind femur wide.

 lateral margins obscurely, yellow ; mieson widely of propodeum, 

 and apex of abdomen rather widely black. Discal cilia of fore 

 wing absent; midlongitudinal line from apex, a little over half
