Characters: Triangles of both fore and hind wings long in the axis of the wing, and generally four-sided by failure of the long sides to meet at the outermost angle; both usually traversed by a single cross vein; bridge vein shortened distally, the distance from subnodus to oblique vein being about a third of the distance of subnodus from the middle fork; gaff nearly as long as the inner side of the hind wing triangle

Fig. 2. The wings of male (basal part) and female Eogomphus neglectus Ndm. for a considerable distance from the wing margin the paired long veins inclose more than one cell row, the greatest doubling between M3 and M4, less between Oil and Cu2, least between Rs and M2; behind Cu2 in the fore wing are two or three cell rows traversed by ill de- veloped accessory branch-like sectors; and middle fork (Mf) sym- metrical. This genus is perhaps nearest to Davidius of the Gomphus series, but it differs in having the fore wing triangle longer and not angulated on the outer side; the intermedian crossveins are little reduced, being 5/2 in fore and hind wings respectively. This character transgresses the lines heretofore drawn between the Gomphine and Epigomphine series, as does also the general aspect of the rather elongate wings. The nymph is unknown. The nymph figured in the Manual on Plate VII, figures 3 and 3a, referred to on page 67 as possibly belonging to this species, is the nymph of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
