Excerpt from The Natural History of British Insects, Vol. 8: Explaining Them in Their Several States, With the Periods of Their Transformations, Their Food, Economy, &C., Together With the History of Such Minute Insects as Require Investigation by the Microscope; The Whole Illustrated by Coloured Figures

The difference between the male and female of the common Emperor Moth is flrikingly obvious; the male is fmaller than the female, and the colours in general darker; the poflerior wings alfo are orange in the male, and not fo in the female; and finally, the two fexes may be determined by the flrué'ture of the antennae: thofe of the male being nearly oval, and very deeply feathered, or peelimated, and thofe of the female being alfo peétinated, but fo {lightly as to appear fetaceous. As the firuéture of the antenna is an unerring criterion by which the fexes are afcertained, the Phalxna Pavonia media is a phenomenon in Entomology, for both the male and female fo perfeélly refembles the female Emperor Moih, P. P. Media, which we have figured, that it may be millaken for the fame fpecies: the female differs in no refpeft from it; and the male only in the form ofthe antennae. We have received this remarkable fpecies from, Italy and Germany. It is figured only by Efler, Pbal. 3. Tab. 3 and is thus defcribed by Linnmus and Fabricius, 6 media fingu-, laris ob foeminam mari fimillimam. The third, P. Pavonia major, can by no means be confounded with the preceding: our fpecimen of it is fix inches in breadth, and IS alfo very. Bulky: it IS found in the Pays de wad. Roefel has given a figure'of both fexes with the larva and pupa. The' winged Infect: is of a dingy brown, the marks fomewhat. Fimilar to thofe of the common kind. The larva is large, with the head..fmall in proportion. /the whole is of a Citron green.
