and the sides of the petiole for the greater part, black. 
Legs coloured like the body, the four front cox pale yellow, 
the hinder largely black on the outer side at the apex and

Face and clypeus strongly punctured, the latter with a 
shallow depression in the middle at the apex; both are 
thickly covered with long white hair; the labrum fringed 
with long white hair. Mesonotum closely punctured and 
thickly covered with short black hair. The top of the

basal slope punctured and thickly covered with long fuscous 
hair. Postscutellum smooth, pale yellow. The basal slope 
of the median area in the centre is bordered all round by a 
stout keel; the areola is about as long as it is wide in the 
middle ; the apical half is obliquely narrowed, the posterior 
median, except at the base, is irregularly transversely 
striated ; the spines are stout and narrowed towards the top, 
which is bluntly rounded. Pleurz closely punctured, the 
metapleurze more strongly than the rest, especially on the 
basal half. Gastrocceli with the basal half deep and irre-
