Description of female plesiallotype. — Length 24 mm; fore wing 
17-5 mm. Body and legs black, clothed with a. very fine, mostly 
cinereous pubescence ; antennae black, orange beyond segment four 
above, beyond the middle of the third segment below; wings trans- 
lucent, strongly tinged with orange, except fuscous at extreme base, 
through most of costal cell, and narrowly along outer margin. 
Clypeus, front, vertex, thoracic dorsum, coxae, and front femora 
each with a few strong setae; abdomen densely setose apically; pro- 
podeum with many fine but fairly long setae on the sides of the 
slope. Clypeus 2.4 X as wide as high, its apical margin slightly con- 
cave; front and vertex very narrow, middle interocular distance .48 
X width of head, .90 X lower interocular distance; upper inter- 
ocular distance only .62 lower, .70 X length of third antennal seg- 
ment; postocellar line 1.4 X ocello-ocular line, the latter only 
two-thirds the maximum diameter of a posterior ocellus. Postnotum 
constricted on the midline; propodeum sloping evenly, with some 
very weak transverse rugae, the median line weakly impressed.
