from the base to the apex of the wing, the second beyond the cell, but scarcely beyond the middle of the wing; the third at a less distance from the base of the second than that is from the first, and directly below a point midway between the tip of the costal nervnre and that of the first superior subcostal nervule; the fourth near the extremity of the wing and but little before the tip of the third superior nervule, or at about two-thirds the distance from the base of the third superior subcostal nervule to the tip of the subcostal nervure; the first inferior subcostal nervule originates of course at the tip of the cell, and separates but narrowly from the main stem, from which it diverges very gradually as far as the base of the outer superior nervule, where the main stem approaches it again; the lowermost inferior subcostal nervule arises from the first inferior scarcely beyond its base, curves inward, downward and then outward before taking a course parallel to the nervule above, from which it is separated at its base by twice the distance that the former is there distant from the subcostal nervure; the vein closing the cell can scarcely be called a vein, but rather a break in the membrane such as is often seen in recent butterflies, and is indicated in the fossil by a curving granulated streak; it arises from the final curve of the lowermost inferior subcostal nervule opposite and directly below its origin; it passes thence in a slightly curved line, opening outward, to the very base of the upper branch of the median nervure. The median nervure runs in a straight line as far as its first divarication, which is a little beyond the middle of the cell; thence it is bent parallel to the subcostal nervure and exactly at the lower tip of the cell forks, the branches parting but gradually from each other, the upper gently curved, the lower nearly straight. The submedian nervure is parallel to the lowest median nervule, as in Neorina, etc. None of the veins are swollen at the base. The cell is three and a half times longer than broad.
In the hind wing the neuration is almost precisely that of Neorina Lowii (PI.II, fig. 8). The costal and subcostal veins are confluent for a short distance, when the costal parts from its neighbor at nearly right angles and immediately thereafter sends up the basal shoot, which, after passing in a straight line half
