Ist or the 3rd; the third cubital cell also trapezium-shaped, widening 
out a little towards the margin of the wing beyond the radial cell. 
The first recurrent nervure terminates in the 2nd cubital cell before its 
apex ; the 2nd recurrent nervure in the middle of the 3rd cubital cell. 
The transverse-medial nervure is interstitial or strikes on the externo- 
medial nervure before the apex of the 1st submedial (interno-medial, 
Smith) cell. The Ist discoidal cell, as in the genera Pepsis, Notocyphus 
and portions of Salus with a hyaline spot formed in the inner angle 
through the upper concave discoidal line. The cubital nervure of the 
hind wing coalesces with the transverse anal nervure (interstitial), 
Legs, very long. Tibiee having neither spines nor hairs, Tibial 
spur, short, The metatarsus of the posterior legs arched. Claws with 
one stout tooth in the middle on their inferior edges. The 3rd 
ventral segment without a transverse impressed line. In the male the 
middle segment is short, shorter than the rest of the abdomen. Coxe, 
trochanters and femora, especially of the anterior legs, thick, Femora 
on the underside having a sharp denticulated edge.

The characters of the maxillz resemble those of the genus Pogonius; 
Dhlb, ‘The lower rim of the orbits reaches up to the base of the 
mandibles. The antenne are at times, as in the genus Ceropales, 
inserted ata distance from the clypeus, at times close to it. Mesono- 
tum, transverse, short, Front wing with three cubital cells; the 3rd 
cubital cell, trapezium-shaped or trapezoidal, much larger than the 
2nd. The radial cell, long, lanceolate. The Ist discoidal cell termi- 
nating in or a little after the middle of the 2nd cubital cell, the 2nd 
discoidal cell in the middle of the 3rd cubital cell. The transverse 
medial nervure unites with the Ist transverse-submedial nervure, or 
| strikes on to the externo-medial nervure before the apex of the Ist 
submedial cell. The cubital nervure of the hind wing is discharged at 
or after the apex of the anal cell. Antenne and legs, long and slender;
