Angaria, gen. nov. 



Areolet small, quadrate, slightly narrowed on the lower 

 side at the apex ; the second transverse cubital nervure is 

 faint; the recurrent nervure is received shortly before the 

 middle and is largely buUated in its centre ; the transverse 

 ba.sal nervure is interstitial. Antennw filiform, longish, fully 

 as long or longer than the body, annulated with white in the 

 middle. Eyes large, slightly converging on the lower side. 

 Mandibles with two sharp, almost equal teeth. Occiput 

 margined. Parapsidal furrows distinct. Metathorax elon- 

 gate, rough, and bearing two transverse keels ; the spiracles 

 small, oval. Petiole curved, narrow, not much widened 

 towards the apex, and is as long as the second abdominal 

 segment ; the s|)iracles are at the base of the dilated part 

 behind the middle. 



lias the small areolet with almost obsolete second trans- 

 verse cubital nervure of Mesostenus, but may be known from 

 it by the longer and much more slender antetmje, by tiie more 

 slender petiole (which is not nearly so much dilated at the 

 apex), by the smaller oval metathoracic s|)iracles, by the 

 smooth and shining median segment, and by the recurrent 

 nervure not being received near the a])ex of the areolet. 

 The scutcllum is roundly convex and narrowed towards the
