Characters from the imago.
The body is divided into three parts, head, thorax, and abdomen; the head has two fixed compound eyes, and two moveable antennae. Insects have six jointed legs in pairs; they breathe by lateral spiracles.
Class, LEPIDOPTERA.
Characters from larva, pupa, and imago.
Larva polypod, bears no resemblance to the imago; pupa quiescent, bears no resemblance to the imago. Imago has four scaly wings, and the mouth aglossate or antliate.
Sub-class, PHALAENAE .
Characters from larva, pupa, and imago.
All varying .
Characters from the larva and pupa.
Larva depressed, kaned; has sixteen feet, lives through one or more winters, never rolls itself in a ring when touched, feeds on the solid interior woody parts of vegetables; pupa changes in a tough cocoon, in which are interwoven particles of the larva's food; it has a double row of small raised denticulations on each segment of the abdomen, which give it partially the power of locomotion.
Family AEGERIIDAE, Stephens.
Characters from the Imago.
Palpi triarticulate, incrassated at the base, acuminate at the apex, prominent, enclosing the antlia; antennae, sub-cylindric, gradually incrassated from the base nearly to the apex, the apex itself acuminate and terminated with a fascicle of hairs; ocelli, two. Flight diurnal in the hottest sunshine.
Characters from the imago.
Palpi very prominent, and densely clothed with scales at the base, in appearance angulated; antlia fine, not so long as the antennae; antennae the length of the thorax, in the male much pectinated, in the female simple; superior wings clothed with scales, inferior hyaline.
Characters from the imago.
Palpi black, yellow at the apex; antennae black, beneath testaceous; fulvous at the base; head black, excepting a white mark before each eye; a yellow ring round the neck; thorax black, with a yellow spot at the base of each superior wing; abdomen black, slightly barbate, with three equidistant yellow belts; superior wings deep fuscous, inferior hyaline; femora and anterior tibiae black, posterior tibiae and all the tarsi yellow.
Inhabits England, but is very rare.
Inhabits Italy.
Inhabits Africa.
Several other species probably exist, with which I have not happened to meet.
The principal distinctions between Memythrus and AEgeria are, that the antennae in the former are not longer than the thorax; in the latter they are much longer; in the males of the former genus they are decidedly pectinated, in those of the latter but obscurely ciliated; in the former the anterior wings are always opaque, in the latter always hyaline.
FINIS.
