14 Cameron, Hymenoptera Orientalia. 



Mesosternum closely punctured ; the base broadly de- 

 pressed, the depression rounded at the apex ; the middle 

 has a crenulated furrow. The areolet is broader than long, 

 and is slightly narrowed above ; the recurrent nervure is 

 received in its middle ; is straight and largely bullated 

 in the middle, as is also the second transverse cubital ; 

 hyaline, iridescent, the costa, stigma and nervures black ; 

 the transverse median nervure is received shortly before 

 the transverse basal. The anterior legs are pale 

 yellow ; the middle pair are darker, with a more fulvous 

 hue ; the tarsi fuscous ; the hinder coxae black ; the apex 

 broadly behind, more narrowly on the outer side, pale- 

 yellow ; the trochanters black ; the femora and tibia dark 

 rufous, the apex and base of the femora above and the 

 apex of the tibiae, broadly, blackish ; the tarsi white, the 

 basal two-thirds of the metatarsus and the apical joint 

 black. Abdomen smooth, shining ; the petiole black, the 

 sides and apex pale yellow ; the other segments black, 

 narrowly yellow on the apices ; the centre of the second 

 segment slightly, the third, fourth, and fifth more broadly 

 at the base, and the sixth and seventh almost entirely — 

 only the sides being narrowly black — brownish. The 

 ventral surface whitish yellow, the apical segments 

 brownish ; the ventral fold is distinct. 



Leptocryptus, gen. nov. 

 Resembles Ceratocryptiis in the form of the body and 

 wino-s, but it wants the frontal tubercles ; the apical man- 

 dibular tooth is longer and sharper ; the prothorax above 

 is more widely and deeply depressed, or incised in the 

 middle ; the metathoracic spiracles are oval, not linear ; 

 the spiracles on the petiole are placed shortly behind the 

 middle, not, as in Ceratocryptus, between the middle and 

 the apex ; and the ovipositor originates from the ventral
