There is another kind of gall, of an irregular shape, formed on oak-leaves. The gall-fly that inhabits it is one of the " Inquilini," and dwells in a cocoon dm-ing the pupa state, and is infested by Callimome mutabilis and Platymesopus tibialis.—Francis Walker.
Description of Eulophus Agathyllus. — Body rather slender, convex, shining, very finely squameous, almost smooth, dark seneous : head as broad as the thorax ; vertex rather broad : front impressed : antennae black, subclavate, rather shorter than the thorax : thorax elliptical : prothorax conspicuous, transverse, narrow in front : scutum of the mesothorax rather short ; sutures of the parapsides very distinct ; scutellum nearly conical : metathorax short : propodeon obconic, declining, granulated : podeon short : abdomen oval, depressed above, keeled beneath, a little broader and longer than the thorax ; metapodeon rather large ; octoon and following segments of mode- rate size ; paratelum and telum small : legs aeneous, black ; tarsi and tips of fore- tibiae fulvous : wings limpid ; nervures piceous ; ulna rather shorter than the humerus; radius much shorter than the ulna ; cubitus shorter than the radius ; stigma small.

On the duration of Hymenoptera in the Larva state more than one season. — Since the instance of some individuals of the Fossores remaining in the larva state one season, at least, longer than others collected at the same time, that I observed a few years ago, as recorded in the ' Entomological Magazine,' I have not met with any instance until this season, when I have observed it among another tribe of the order, Ichneu- monidae. In the latter part of the autumn of 1844, 1 gathered a dead stem of a plant about eight or ten inches long, with a dense cottony mass surrounding it, about the size of a large hazel-nut, I put it in a tin pocket-vasculum which I had with me, when I got home I put it by without remembering what was in it. I had no occasion for it again until July, 1845, when I opened it and saw what I had enclosed ; I be- gan to examine the mass of cotton, I observed in the centre of it the remains of seve- ral small cocoons about a line in length, and near about a dozen larvae which had not begun to form any cocoon. I observed them from time to time ; for about a month they remained in the same state (without any of them changing into pupae) until they died, which I believe was hastened by opening the cotton and disturbing them, as I have several times observed that the larvae of Hymenoptera generally die after their abode has been opened, and they have been moved about afterwards. — James Bladon.
