Forewings dentate, pulverulent, of a rather lighter grey than C.unijuga.... Median lines black, single, not very distinct. A whitish space before the large bisannulate concolorous reniform. sub-reniform likewise whitish, closed, joined to the t. p. line, the latter jagged but without very prominent discal teeth. making a deeper and narrower sinus altove vein than in C. unijuga. Subterminal upright. dentate, shade (preceding the blackish line) distinct.

The identity of Pamphila pocahontas and quadaquina with the typical species zabulon has been universally acknowledged, although there exists no more positive proof than the fact that no males of these forms have ever been discovered. I have in my collection an intermediate specimen exhibiting plainly the characters of the original species and of the variety and sub-variety, and apparently a link between them.

In a recent article in the Entomologist it is proposed to obviate the confusion in which our nomenclature is involved, by accepting the names most generally in use and allowing the law of priority (if it does not make too much trouble!) to determine all questions which may hereafter come up; ignoring entirely the claims of older authors and of writers holding different opinions from the Proposed of the scheme.

This interesting little beetle, of which we give an enlarged drawing, as well as a representation of its larva, in fig. 18, is a very destructive creature, dreaded by every Entomologist who has had any experience of its ravages. Its larva is very destructive also in some carelessly kept provision and household stores, affecting hams, bacon, old cheese and other substances. It is a European insect, which has long been naturalized in this country, where it seems to be quite as much at home as in its native land.

The following notes were suggested by “Observations,” &c" on Aphides in The Canadian Entomologist for July, 1873. The species noticed on Rumex crispus seems to have very much resemblance to A rumicis of Europe; some other species of N. America do not differ from those of Europe, but have been probably introduced by means of shipping. With regard to European Aphides it is well known that the winged female of many species appears in the spring, that the wingless female is more fertile than the winged one, that the winged state is, partly at least, by means of the diminution of quantity or alteration of quality in the food, and that the winged state enables the species to have a change of habitation and thus to continue its race till the autumn.
