Genus Pseudogomphus .

Male. Eyes contiguous, frontal tubercle slightly bifid; labium cleft. Wings long and rather pointed, triangles rather small, free, those on the hind wings rather longer than those on the fore wings: fore wings with 6-8 cross-nervures in the lower basal cell, and four supratriangular nervures: hind wings with 2 or 3 supratriangular nervures, and 5 in the lower basal cell; membranule rather large; inner margin concave between this and the anal angle. Abdomen with the appendages of the second segment large, upper anal appendages about as long as the lower, which is broad and truncated; at their base rises a strong vertical conical spine, pointed at the apex.

Probably allied to Cordulegaster, but very distinct from any described genus.
