208 HYMENOPTEEA. 



slope and as long as the mesothorax. Abdomen subsessile, as long as the thorax; 

 the apex acute, covered with long silvery hair. Legs very long and slender, densely 

 covered with silvery pubescence ; the front metatarsus incised at the base ; the tibial 

 spines few ; the long spur of the hind tibiae reaching to the middle of the metatarsus. 

 Wings long ; hyaline, with a cloud across the radial and the second and third cubital 

 cellules ; the basal nervure not interstitial ; the second cubital cellule at the top and 

 bottom shorter than the third and narrowed towards the top; the first recurrent 

 nervure received beyond the middle, the second curved and received shortly before 

 the middle; in the hind wings the anal nervure is received in front of the cubital 

 nervure.

Hab. Mexico, Temax in North Yucatan (Gaumer). 



Antenna? thick, the apical joints slightly dilated ; the third and fourth joints sub- 

 equal ; the flagellum fuscous beneath. Eyes distinctly converging beneath ; the hinder 

 ocelli separated from the eyes by, if anything, a less distance than they are from each 

 other ; the face with a sparse whitish pubescence, shining, and with a bluish tinge ; 

 the inner orbits yellow. Prothorax as long as the head ; the apex arcuate. Scutellum 

 raised, hardly narrowed towards the apex. The median segment with a gradually 

 rounded slope. Abdomen as long as the thorax ; the apex with a silvery pile ; the 

 penultimate ventral segment not incised. Legs moderately long ; the front claws 

 bifid ; the fore metatarsus curved at the base ; the spines and spurs white ; the hinder 

 spurs thick, the longer one reaching beyond the middle of the metatarsus. The third 

 cubital cellule is shorter at the top and bottom than the second, and at the top is half 

 the length it is at the bottom ; the anal nervure in the hind wings is interstitial. 



Easily known from P. torolce by the legs having the spines and spurs only white, by 

 there being only one white band on the abdomen, by the third cubital cellule being 

 shorter than the second, and by the interstitial anal nervure in the hind wings.
