UandlireohJ CANADIAiq- FOSSIX INSECTS 101 analysis shows, with great probability, that the fossil indicates a new Fig. 3.—Archiinocellia oligoneura, Handlirsch. Front and hind wings in situ. This well-preserved specimen is about 7""^ long, and permits the assumption that the total length of the wing was from 12 to 14°™. The costal area is not preserved. The pterostigma, togethe'r with the apex of the wing, are injured, and it caunot be determined with certainty whether cross-veins were present in the former. In the subcostal area of each wing there lies proximally from the stigma a cross-vein, which, judging from its position, cannot correspond to the cross-vein occurring near the base of the wing in recent species of Rhaphidia; but to the more distally situated cross-vein in the wing of the genus Inocellia. The sector radii arises rather near the base of the wing, and forms a large fork, the branches of which again divide into three branchlets. Between the sector and radius there are only two cross-veins; the first of which Has just below the furca- tion, and the second directly posterior to the second branching; while in all knovm recent species of Inocellia three cross-veins are present, the first of which is placed proximally from the large fork. As in most species of the genus Rhaphidia, only two closed cells lie between the radius and its sector. In the large fork of the sector there is also a cross-vein. The media is connected with the sector radii by three cross-veins, the second of which in the front wing is situated distally from the large furcation of the sector, but in (the hind wing is anterior to this fork. The trunk of the media terminates in a short bifurcation, the branches of which always dichotomize only once. The second long main branch of the media, which originates just 3337—2.
