In the fore wing the cross vein between radial ramus and media

Venation of fore wing and hind wing, x 27. 
The distal portion of the subcosta, which forms the basal boundary 
of the pterostigma, is clearly recognisable and fairly distant from 
the point of origin of the radial ramus. 
Terminal joint of maxillary palp relatively slender. First joint 
of posterior tarsus with about 27 ctenidia ; the same joint 0°7 mm. 
long, second joint 0:06 mm., third joint 0°11 mm.
