HyDienoptera Orientalis. .IJ.3 



The face is densely covered with long silvery white hair ; 

 the front and vertex densely pubescent and covered 

 sparsely with long gray hair ; clypeus rounded. The 

 central incision narrow ; eyes slightly converging towards 

 the bottom ; mandibles reddish ; black at base and apex. 

 Antennai pubescent ; the third joint fully one-half longer 

 than the fourth, which is a little longer than the fifth. 

 Thorax densely covered with a silvery pile ; the pronotum 

 above, the metathorax and the pleurae thickly covered with 

 cinereous hair ; a thick line of silvery hair along the tegulaj 

 on the mesonotum ; finely punctured ; the scutellum shining,, 

 bearing distinct punctures, and furrowed down the centre. 

 Median segment with some stout transverse furrows, 

 opaque ; rounded and narrowed at the apex and nearly as 

 long as the mesothorax. Petiole black, covered with grey 

 hair ; and one-half longer than the hind coxae. Abdomen 

 shining, indistinctly punctured, elongate, sharply punctured 

 at base and apex ; the apical segments more distinctly 

 punctured. Legs longish ; broadly black at the base ; the 

 tibial spines red ; the tarsal reddish in part ; the calcaria 

 black, red at the extreme apex. The second cubital cellule 

 is oblique, of equal width at top and bottom and receives 

 the recurrent nervure a very little beyond the middle ; the 

 third cellule is longer at the bottom than the second, but at 

 the top is less than one-fourth of the length ; the recurrent 

 nervure is received before the middle of the cellule. 



The $ does not differ in coloration or sculpture from 

 the $. The tegulae are reddish. The form of the cubital 

 cellules and the position of the recurrent nervures vary. 



In form this species approaches closely to S. piibescens ; 

 but the black legs of that insect distinguish it at once.
