The costal nervule terminates slightly beyond the middle of the costal margin, its basal two-fifths presenting a considerable and almost uniform expansion, which tapers rather rapidly at the tip, and reaches nearly to the middle of the upper border of the cell. The subcostal nervule is very slight on the basal half of the wing, closely connected with the posterior surface of the swollen portion of the costal nervure and only divaricating from that vein after the latter has lost its tumidity; it emits its first superior nervule at slightly more than three-fifths the distance from the tip of the bulbous portion of the costal nervure to the upper apex of the cell; its second at midway between the origin of the first and the tip of the cell; its third at midway between the upper apex of the cell and the origin of the fourth, which arises at about two-fifths the distance from the base of the third to the outer border of the wing. The first superior nervule terminates near the middle of the outer two-thirds of the costal border, the second midway between the apex of the first and third; the third terminates just above, and the fourth at or scarcely below, the tip of the wing. The first inferior subcostal nervule arises at a very short distance beyond the base of the second superior nervule, and curving rather strongly, terminates in the middle of the upper half of the outer border; the second inferior nervule is emitted from the first inferior as far beyond the base of the latter as that is beyond the base of the second superior nervule; at its origin it is directed inward as well as backward (forming the upper termination of the cell) and passes backward in a small, narrow and rather strongly curved bow, bent below more than above, beyond which it assumes a course nearly parallel to the first inferior nervule; just beyond the arcuate portion it is connected by a rather long, straight, oblique nervule, directed considerably outward as well as downward, to the origin of the upper median nervule. The median nervule is slightly enlarged at the base, and diminishes gradually and regularly in size to its first divarication, which is scarcely beyond the middle of the cell; the origin of its middle branch is slightly nearer the origin of the basal than of the terminal nervule; the latter strikes the middle of the outer border. The submedian nervure is straight and not swollen at the base. The cell is three times as long as broad, and scarcely more than half as long as the wing. The article from which the above is quoted, as originally written, closes thus:
