$ . Black, clothed with long white hairs, those near the orbits of 

 the eyes of a slightly sooty colour, and those of the mesonotum with 

 a greyish tinge, wings hyaline, nervures pale testaceous. Clypeus 

 so densely clothed witli snowy-white hairs that its sculpture and 

 form are invisible but regarded anteriorly, with the insect upside- 

 down it is seen to be semicircularly emarginate, and the labrum 

 bears a transverse emarginate tubercle. Antennoe rather short, the 

 2nd joint of the flagellum almost as long as the 3rd and \ of the 4th 

 together, those from the third upwards subquadrate, if anything 

 appearing a little longer than wide, mesonotum dull, finely and 

 rather closely punctured, the punctures distant from each other 3 

 or 4 of their own diameters, the sculpture, however, is exceedingly 

 diflBcult to see as the hairing is so dense ; legs sparingly clothed with 

 white hairs, propodeal area finely rugulose, abdomen shining, 1st 

 segment sparsely clothed with long erect white hairs those of the 

 following short and semi-adpressed, 2nd and following segments 

 closely and finely punctured ^t the base, their apices widely impressed
