Others forming open nests are some of the species of P(jlygonia, while more complete wel)-conccalinents are made hy the cateri)illars of Aglais milherti and some of the Melitacidi. The mere partial curling of a leaf so is to conceal tiic sides of the creature lying thereon answers the ])urpose of Jasoniades glaucus, while its neighhor Euphocades troilus turns the leaf completely over so that the opposite edges touch. I)ut the group, which above all others contains caterjiillars living in concealment is the Ilcsperidae, the higher Ilesperidae making an oval enclosure hy strong strands of silk connecting the edges of leaves at wide intervals, while the Pamphilidi construct burrow-like nests by sewing together the edges of neighI)oring i)lades of grass ; hardly an instance i? known, where one of them lives ojjenly. Diitterfly caterpillars which live exposed have many of them special modes of guarding against danger, some falling to the ground and curling up at th(! slightest shock or alarm, such as many of the ^lelitaeidi in their later stages. Otiiers fall with greater deliberation, first attaching a thread to the leaf from which they drn[), such as Ilypatus l)aehmanii and Strynior titus. Others assume a Sphinx-like attitude which they may retain for a long time, as is the ease with Vanessa huntcra in its earlier life, and in this the
