tlie pro- and nicsopleiiraj strongly punctured, tlie former exca- 

 vated in tlie centre, the latter with a broad shallow oblique 

 furroAv in the middle ; the mctapleurae with an oblique crenu- 

 lated depression down the centre, the apex coarsely punc- 

 tured. Petiole flat above, impunclate, covered with long 

 white hair, the sides above and at the apex rufo-testaceous ; 

 the other abdominal segments covered closely with white 

 hair, the apex of the second and third segments broadly, and 

 the other segments entirely, rufo-fulvous ; beneath, the 

 petiole and the second segment are rufo-fulvous at the apex. 

 Legs covered with white hair; the fore tibias and tarsi in 

 iront, the middle tibise in the centre in front, the basal joint 

 of the middle tarsi entirely, the hinder tibiae, except a 

 black line in the centre behind, and the metatarsus, except 

 at the extreme apex, yellowish testaceous. The wing- 

 nervures are fulvous, the stigma black ; the first transverse 

 cubital nervure is broadly curved and narrowed towards the 

 second, the second and third nervures are straight, oblique. 

 The second cubital cellule is much narrowed at the top, being 

 there not much more than the distance bounded by the re- 

 current and the first transverse cubital nervures ; the first 

 recurrent nervure is received quite close to the base of the 

 cellule, the second shortly before the middle and is largely 

 bullated at the top, the three transverse cubital nervures 

 beiiig also shortly bullated near the bottom ; the tegul^e and 

 the tubercle beneath them are yellowish.
