Ilymenoptera from JSurthern India. 301 



second recurrent nervure is received near the apex of the 

 basal third of the cellule; the two recurrent nervures are 

 separated by the length of the top of the first cubital cellule 

 from each other. Legs pruinose; the spines and calcaria 

 black. Abdomen with the segments banded with silvery 

 pubescence ; the pile on the pygidium is dark golden in 

 certain lights ; the hypopygium is slightly triangularly 

 depressed at the apex. 



Comes near to L. nigripennis, Cam. ; that may be known 

 from it by the head and thorax having a golden pile, by the 

 pile on the pygidium being golden, by the apex of the 

 median segment being more closely and uniformly trans- 

 versely striated, by the femora having golden hair, and 

 it is altogether a larger and stouter insect.

Scape of an tenure shining, densely covered with silvery 

 pubescence, the flagellum with a pale pile : the pedicle 

 densely pilose. Front and vertex closely punctured, the 

 vertex less closely behind the ocelli, the front densely 

 covered with white pubescence, the ocellar region raised, a 

 shallow furrow down the middle; the depression behind 

 them is deep in the middle. The apex of the clypeus is 

 shining, bare, slightly wrinkled. The mandibles behind 

 the tooth are finely rugose, pilose; palpi dark testaceous. 

 Mesonotum densely punctured and thickly covered with 

 fuscous pubescence. Scutellum shining, less closely punc- 

 tured; postscutellum finely rugose. The basal part of the 

 median segment is irregularly longitudinally striated, the 

 apical closely finely reticulated ; the apex has an almost 

 perpendicular slope and is transversely striated. Propleurae 

 shining; mesopleura? closely and distiuctly punctured, the 

 tubercles behind thickly banded with silvery pubescence, 

 the perpendicular furrow is crcnulated ; the metapleurae 

 closely, slightly obliquely, striated. Mesosternum closely 

 punctured, thickly covered with white pubescence ; the 

 metasternal process is depressed at the base, raised at the 

 apex ; there is a stout keel in the middle at the base. 

 The first cubital cellule is double the length of the second 

 on the top, the first transverse cubital nervure has an 

 oblique slope near the middle ; the second recurrent ner- 

 vure is received shortly behind the middle. Legs thickly
