Forewing: elongate, some incomplete specimens suggesting that a greater elongation is possible than in the specimen figured by von Rosen (1913 : pi. 27, fig. 7). Sc short and single. Rx forking distad or basad of humeral suture, the outer branch terminating on the anterior margin at 0-2-0-4 of the forewing length (as measured from the suture). R2 and R3 elongate and separate at suture, R2 sometimes forked. Stem of Rs terminating near wing apex with a more or less marked anterior curve in its distal part. Rs with about four branches to the anterior margin, the outer ones usually subdivided. M and Cu separate at suture, the former closer to Rs than CuA with one to three major branches distally and perhaps several short branches towards base. In the left forewing of In. 17143 and right forewing of , M is briefly linked with Rs near base. Rs and CuA are closer in some specimens than in von Rosen's figure with M nearly median. CuA occupies about half of the wing area, dividing some ten times, the branches frequently forking once and occasionally several times. Humeral suture arcuate with maximum apical extension near M, and the basal part of the forewing is usually downcurved anterior to Rs. A brown pigmentation is often preserved on the scale, parts of M and on the more anterior veins. Forewings are preserved in 24 specimens and probably in two others. Hindwing: elongate, rounded apically; anterior and posterior margins nearly parallel, apex nearer the latter. Sc single, elongate, on average about five times as lon
