To quickly assess the difficulty of the text, read a short excerpt:
ocelli yellowish, broadly bordered at inner side with dark brown. Two small dusky spots behind ocelli. Anterior angles of pro- thorax pale dusky, and two small, dusky, transversely linear spots, usually more or less indistinct, on the middle of the pro- thorax. Wings faintly dusky, the stigma, subcosta anddiscoidal vein darkest, the two branches very faint, though normal in their course. Surface of wings quite profusely granulate or scaly. Antennae dusky, short, scarcely as long as the head is ...broad, the two basal joints almost equal in length, the first slightly longest and stoutest, narrowest at base, truncate at tip; the second almost as long as wide, rounded and stoutest at tip ; both joints quite distinctly scaly; joint three is rather robust, diminishing but slightly and gently toward the base, connecting with the second joint by a very short though well separated petiole. There is no basal constriction and, apparently, only the upper sensorium present, which is rather stout and somewhat oval ; surface quite coarsely scaly with the lower third sharply annulate ; from 3-4 distinct, short bristles surround the apex, the two terminal ones stoutest.
