separation (along the ridge representing the mesopleural 
suture) from a dark spot near the ventral end of the 
meso-metapleural suture; remainder of mesopleura, except 
dorsal portion of mesepisterna, suffused with orange ; meso- 
metapleural and metapleural-propodeal sutures marked with 
black lines; lateral areas of metasternum black; all coxae 
black at base, at least anteriorly ; remainder of legs partially 
suffused with orange; veins and membrane of fore wings 
yellowish basally, and somewhat fuliginous in the region of 
the first submarginal and marginal cells, the latter with a 
dark streak in the anterior half ; hind wings yellowish ; an- 
terior face of first tergite more or less ferruginous, with a 
black basal area which (in the holotype and one paratype) 
has a narrow median projection and broad extensions at the 
sides (the other paratype has only a median projection which 
is shorter and does not reach the dorsal surface) ; apical and 
to some extent the lateral margins of all tergites orange; 
basal margins of tergites 2-5 orange or black (always black 
on tergites 4-5), each with a triangular median projection 
of the same color; sternites variously marked with orange 
and black. 
Head (in facial view) broader than long, the posterior 
margin nearly straight; inner margins of eyes nearly 
straight, slightly converging anteriorly, nearest to each 
other where they reach the clypeus; clypeus emarginate 
both anteriorly and posteriorly (fig. 1), the peak of its con- 
vexity (seen in profile) anterior to the middle; supra- 
clypeal area posteriorly three times as broad as long, the 
sutures defining the frontal shield ( Stirns childs chen ) not 
distinct ; antennal sockets separated from the eyes and from 
each other by somewhat less than their transverse diameter ; 
space between the antennal sockets with a low ridge, cari- 
nate posteriorly; supra-antennal area with a broad median 
impression which extends posteriorly and encircles the an- 
terior ocellus; posterior ocelli smaller than the anterior 
ocellus, separated from the eyes by one and a half times 
their diameter, and from each other by twice their diam- 
eter ; latero-posterior margins of each posterior ocellus bor- 
dered by an impressed line which continues posteriorly in a 
medially concave curve to the vertical face of the occiput; 
gense (in lateral view) rather narrow, wider below. Man-
