Indo' Chinese Uymenoptera. 485 



sparsoly punctured, vertical area longer tlinn its greatest 

 breadth, slightly narrowed antcM-iorly ; the head swollen 

 behind the eyes. Rlesonotuni ob.soletely punctured, the 

 median lobe divided tVom base to aj)ex by a deep /groove in 

 which lies a low carina. Scuteliuin coarsely punctured, 

 raised into a conical tubercle; niesoplcurra coarsely rugulose. 

 Abdomen smooth. The apical fuscous mark on the tore 

 wing is jialor than the median fascia and occupies almost the 

 wliole of the fourth cubital cell and the extreme apex of the 

 radial cell. The median fascia crosses the wing from the 

 basal half of the stigma and does not extend apically beyond 

 the second transverse cubital nervure. Tliediscoidal m.'rvure 

 is separated trom the base of the cubital nervure by a distance 

 about equal to the length of the first transverse cubital 

 nervure.

 differ appreciably.
