The Htnglo spccimun represents a friigment of a front wing nnfortunntely very iini)er- fcct, but still sufBeiontly preserved to shov that it is a Lithoniylaeris, allied to Ij. jmhU' aylvanica, but much larger than it, and ccruiinly distinct from any known s|)ecies. Not one of the borders is preserved, although in several places the vnns are evidently perfect to their tips. Only one or two of the mediastinal veins can bo seen, the outer one long and straight and minutely forked at the tip, with no other offshoots, unless it be at the l)ase, showing the insect to belong to the Mylacridae; within this the forked extremity of another parallel vein can be seen. The scapular vein is [)erfectly straight as far as what is probably the centre of the wing, and in this basal portion runs down the middle of the wing, thns prov- ing its proper reference to this gonus; beyond this it curves very gently and slightly up- ward; in the fragment it emits four branches, the basal two close together, the others far apart, and the last at the very tip of the piece; the first is simple, the second and third simjily forked at no great distance from their origin, and all run in a longitudinally ob- lique direction, subparallel to the mediastinal vein. The cxternomedian vein is exactly parallel to the scapular and hardly more distant from it than two adjoining scapular branches from each other; it divides far toward the base, apparently opposite the middle of the anal furrow and just beyond the second branch of the scapular vein, each of its branches again forking opposite the extremity of the anal furrow, and the uppermost branchlet again before the end of the fragment is reached. The intcrnomedlan vein is en- tirely composed of very faintly impressed lines, emits two parallel arcuate branches cl
