Being much interested in the Tineidæ, Mr. chambers' articles on this family of moths are the first to receive attention as the successive numbers of your magazine come to hand.

I have had the satisfaction of rearing from their larvæ many of the winged gems described in your pages, among others the twospecies named above. Now, as Mr. C. seems to have been in some doubt as to his own determination of these specics, of which he has as yet-as he informs me seen only the imagines, it occurs to me that a description of their larval characteristics might affors some aid in deciding the doubtful points.

I am now able to give the results of my attempts at raising the caterpillars of the three Argynnides, Cybele, Aphrodite and Diana, from the egg, this past season. In August and. early in September, 1873, females of cybele were easily obtained, and a few of aphrodite, which is a rare species here, and these were shut up in kegs, within which were placed pots of growing violets. The eggs rvere laid abundantly on the leaves and stems, and on the cloths which covered the kegs.

Kaltenbach is publishing a work entitled Die Pflanzen-Feindeaus der Classe der Insecten, two parts of which have appeared and carry the investigation through the willows. He enumerates all the German insects known to feed upon particular plants ; annotated lists of more than three hundred species of insects are sometimes ascribed to a single tree.

“Of all the painted populace that live in fields and live ambrosial lives,” there is scarcely a family better known than those which compose the last of all the tribes Hard-shells, the Coccinellidæ. To the young and to the old, to the illiterate and to the scientist, they are equally familiar and equally interesting. Popular sympathy is extended towards them by the elders because they do much good in preventing the excessive multiplication of Aphides; by the juveniles because they are very pretty.

The discussions upon the subject of nomenclature in Zoology, and especially in the department of Entomology, have recently become very perplexing to American students. Many who have been unable either by want of time or lack of opportunity, to consult old works, which are to be found in but few libraries, are called upon suddenly to decide for themselves, whether they will or will not adopt changes in the names of some of the most familiar and best known objects.

Des.–Body cylindrical, tapering gradually anteriorly, 12-jointed, exclusive of head. Head sub-elliptical, thickly punctured, moderately pubescent and of a yellwish brown color. Oral appendages largely developed. Antennæ 3-jointed, cylindrical, acuminate, the basal joint very long and quite thick. A dark purplish curved band passes from the crown of the head to the right antenna. Prothorecic segment surmounted by a transversely elongated, punctated, corneous saddle, concolorous with the head.

Expands I 4/5 inches. Primaries light gray, the outer third brownish, with a triangular gray spot near the apex. A narrow black line near the base of the Wing extends from the costa to the submedian vein. Parallel to this and farther out, a black patch, narrowest at the costa and broadest on the second median veinlet, extends nearly across the wing. ending at the submedian vein. A triangular black patch surrounds the brownish reniform spot, and immediately back of this a curved black line reaches from the sub-dorsal vein to the second median veinlet.

The insect-catching powers of those curious plants, the Fly-traps (Dionæ), the Sun-dews (Drosera) and the Trumpet-leaves (Sarracenia) have always attracted the attention of the curious, but renewed interest has been alvakened in them by virtue of the interesting experiments and observations on their structure, habit and function, that have lately been recorded, and especially by the summing up of these observations in some charming papers by Prof. Asa Gray, which recently appeared in The Nation and The New York Tribune, under the title of “Insectivorous Plants.”

In a recent issue of the Canadian Entomologist, No. viii, Vol. vi, there appears from the pen of Mr. Scudder a paper on “The Linnean Signification of the Generic Term Papilio,” containing some statements on which I propose to offer a few remarks.

The data given by Scudder from Linné's works are-save some minor typographical errors-correct, excepting in two important points. On p. 144 he says “in the year 1846 the first edition of the Fauna Suecica was published, in which Linne for the first time treats of species, giving to them names in the language of the country,” (The italics are mine.)

Male expands 1.45 inches. Primaries above fulvous. Subcostal, submedian and subdorsal veins black at the base. Stigma black and conspicuous, followed by a dusky shade. A small black line at the extremity of the disk is preceded by a yellowish white or semi-transparent spot in the disk ; a similar spot, triangular in shape, appears between the first and second median veinlets at their divarication, and two others between the sixth and seventh subcostal veinlets

“Ignorato genere proprio, nulla descriptio, quamvis accurate tradita certum demonstret; sed plerumque fa11at.”-Cæsalp. apud Linn., SystNat., xii, 1, 13.

In the first part of this essay I endeavored to show the confusion which resulted from the application of the law of priority to the names employed in the early development of our science by persons who had no idea corresponding to the law which has since been formulated. We will now attempt to discuss the second great fallacy in the exegesis of the writings of the founders of the science ; the selection on principles, more or less arbitrary, but always opinionative, of generic types, when these have not been explicitly mentioned by the author.

In many respects the Catocalas are among the most interesting of the moths. The contrast of color between their fore and hind wings renders them objects of great beauty, and hence these fair forms of the woods are eagerly sought after by collectors. My spare time this season was spent in collecting Catocalas. In this part of the country they may be found from the first of June till the first of November.Amasia and ultronia are seen first; I took a fine amasia on the 29th of May, and an ultronia on the 10th of June, cara and several other species may be found as late as the first of November.
