The following ac-count is copied from Mr. Hubbards Orange Inse ts. This insect receives its name from the curious hairy appendages which cover theback and project from the sides of the larva, and have a backward twist, like locksof disheveled hair. These are, in fact, fleshy hooks, covered with feathery, brownhairs, among which are longer, black, stinging hairs. The cocoon is almost spherical,like that of the Saddle-back caterpillar, and is defended by the hairy appendageswhich the larva in some way contrives to leave upon the outside. These tufts giveto the bullet-shaped cocoon a very nondescript appearance, and the stinging hairsafford a very perfect protection against birds and other insectivorous Fig. 48 —P. pithecium (after Riley); A,coon—natural size (after Hubbard). 144 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. Unlike the preceding species, the Hag-moth larvse do not seek to hide away theiroocoons, but attach them to leaves and twigs fully exposed to view, with, however,such artful mauagemeiit as to surroundings aud harmonizing colors that they are ofall the group the most difficult to discover. A device to which this insect frequentlyresorts exhibits the extreme of instinctive sagacity. If the caterpillar can not findat hand a suitable place in whic h to weave its cocoon it frequently makes for itselfmore satisfactory surroundings by killing the leaves, upon which, after they havebecome dry and brown in color, it places its cocoon. Several of these caterpillars unite together, and selecting a long and vigorous im-mature shoot o
