the femora below on the posterior legs, yellow ; claws black toothed, 
the tibial spur of the intermediate legs double. Abdomen black 
pruniose, two spots at the apex of the petiole, a spot on either side 
at the base of the 2nd segment, a larger spot following it, a band 
interrupted in the middle at the base of the 3rd segment, and two 
sub-marginal spots below on the ventral side of the 2nd and 3rd seg- 
ments yellow, the underside of the petiole has a ferruginous stain, and 
the posterior margins of the 3rd to the apical segment are narrowly 
testaceous. 
The & closely resembles the @ but has the wings darker, of a 
brownish bronzy tint, the thorax is more compressed and the antennze 
not so thick, 
This species I found not uncommon in February and March fre- 
quenting the dry beds of streams and clearings made in the forest for 
cultivation. I have named it after Mr. T. A. Hauxwell, Deputy 
Conservator of Forests, who has been good enough to collect for me 
at various times, and to whom my collection is indebted for many 
beautiful specimens of rare and new species of Hymenoptera. 
This species also belongs to the division which construct a globular 
nest and live in pairs.
