and separated from the basal, is a short, wider, and 

 deeper furrow. The pro- and meso-pleuras are shagreened; 

 the latter has a wide and deep longitudinal furrow in the 

 middle ; the metapleurae are shagreened at the base ; the 

 rest smooth and shining. The second cubital cellule at 

 the top is as wide as the space bounded by the recurrent 

 and first transverse cubital nervures ; the upper part of 

 the second transverse cubital nervure is curved ; the 

 lower straight, only slightly oblique ; the second recur- 

 rent nervure is interstitial. The four front tibiae are for 

 the greater part dark testaceous ; the hinder pair broadly 

 dark testaceous at the base ; the calcaria pale. Abdomen 

 shining, impunctate, densely covered with white pube- 

 scence towards the apex ; the five apical segments cream- 

 coloured at their apices, the last more broadly than the 

 others.

 the outer orbits except at the top, covered with longish, 

 silvery pubescence ; the mandibles piceous towards the 

 apex ; the palpi pale yellow. Antennae entirely black, 

 the scape covered with white hair. Thorax black ; the 

 mesonotum very shining, and with a bluish tinge ; the 

 pubescence on the pro- and meso-notum and scutellum 

 dense, pale, that on the post-scutellum longer than on the
