. Catalogue of the described Lepidoptera of North America. Prepared for the Smithsonian Institution. Lepidoptera -- North America. xii INTRODUCTION. by the anterior margin and the posterior, is called the anterior an- gle, D, on the secondaries; on the primaries, this angle is called the apex; the angle between the posterior and interior margins E, is called the posterior angle on the primaries, and the anal angle on the secondaries. In many of the Tineidae, the interior margin and posterior angle are wanting, because the wings are very narrow and lanceolate, the edge proceeding in a regular curve from the apex to the base, figs. 27, 28. The external limit or boundary of the wing is the Unea limbalis, the scales extending beyond that are called the fringe, cilice, fig. 20, F. In some micro-lepidoptera, especially in those with narrow wings, these cilice are hair form and very long, and often longer on the secondaries than the breadth of the wing. A line of darker shade, parallel with the margin, often runs through the fringe. The margin is straight, rectus, when it proceeds in a straight direction; curved, when it forms a concave curve towards the base, fig. 20 ; sinuate, when it makes a convex curve towards the base, fig. 24 ; entire, when it forms an even, straight, curved or sinuate line, fig. 24 ; undulate, when it makes small rounded indentations, fig. 20 ; dentate, when there are sharp, angular, closely connected, teeth- like projections, fig. 21 ; cucidlate (hood shaped) when small, rounded emarginations run into sharp angles toward the base, and lobate, when these emarginations are larger, fig. 23.
