The larva, is twig-like, elongate, with small humps and lateral projections, andlives on trees. The pupa is subterranean. -B. ynopharia ashen, the wings clouded with fuscous, and dusted with blackscales, with four black dentate lines. A species of Boarmia,figured by Mr. Glover, eats the flowers of the cotton, being-found early in October. The larva is of the same thicknessthroughout, with a rather large head angulated above, and twotubercles near the tip. It is brown, with a double lateralpale stripe. The chrysalis is brown and enclosed in an under-ground cocoon. The moth expands nearly an inch and a 323 and is ash colored, sprinkled densely with brown speckles, withthree angulated, transverse, black stripes. Geometm and its allies (Nemoria, lodis, and RacheOopila),have smooth, round or angular, entire wings, which are greenoften with whitish lines. Geometra is the largest genus; ithas pectinated autenme, and the larva is rather short, downy,with several dorsal humps. The pupa is enclosed in a trans-parent cocoon amongst moss. (Stainton.) G. iridaria pea green, with two broad bands, and the costa of the forewings is white sprinkled with rust red. A great man} species, often difficult to identify from thesameness in their markings, are comprised in the genus Anila-//«, which is known by its rather thin wings, with the edgesusually entire, and with stripes and bands and other nun-kingscommon to both.
