constricted at the middle ; dorsum, posterior face and sides of propo- 
deum weakly, finely granulose, with sparse black setae, and the dor- 
sum with a U-shaped mark of waxy- white scales, the sides of the U 
at the lateral margins and the base at the posterior margin, thus the 
anterior and lateral margins of the pronotum and the lateral and 
posterior margins of the dorsum of propodeum outlined by an irreg- 
ular line of waxy-white scales, the lateral marginal lines only very 
slightly discontinuous on account of the very narrow, transverse 
mesonotum; pleural areas weakly, finely granulose, clothed with 
scattered waxy-white scales, but the latter more numerous on the 
meso-metapleural area; legs clothed with sparse black setae and with 
scattered waxy-white scales on the coxae, trochanters, femora and 
tibiae; tarsal claws simple, not toothed; pulvillus absent; calcaria 
i -i-2, white. 
Abdomen without a distinct petiole, the first segment greatly nar- 
rowed anteriorly, triangular in outline, nodose, but approaching sub- 
sessile to the second segment; first tergum finely, weakly punctate, 
clothed with sparse black setae and with a pair of spots at the postero- 
lateral margins of close, waxy-white scales, the two spots separated 
by a distance equal to one-third the width of the posterior margin 
of the tergum; second tergum shining, with fine, weak, separated 
punctures, clothed with sparse, black setae, and with a pair of spots 
at the postero-lateral margins of close, waxy-white scales, the two 
spotes separated by a distance equal to half the width of the posterior 
margin of the tergum ; felt lines of second tergum composed of fuscous 
hairs, inconspicuous; remaining terga shining, with weak, fine, sep- 
arated punctures and clothed only with sparse, black setae; pygidial 
area undefined.
