THE BUTTERFLIES OF HILDESHEIM.
OUR country~nan, Mr. A. R. Grote, has
signalized his appointment to the charge of the Roemer Museum in IIildesheim by
establishing an issue of papers under the title Mittheilungen. These appear by numbers in imperial octavo, very handsomely printed and illustrated. No. 8 is concerned with the butterflies of IIildesheim and is by Mr. Grote himself, as four previous numbers, have been (44 pp., 4 pl. ) Its subject would not much interest American naturalists did the paper not go far beyond what the title indicates, being mostly concerned with a general
classification of butterflies (or at least those of Hildesheim), which in several points
differs materially from c1assific:itions in vogue, if any can be called in vogue in this time of flux.
Butterflies are first divided into two grcat groups, the Parnassi-Papilioniilae and the Pieri-Hesperiidae. The first contains the two groups indicated by its title, regarded as families. The second includes ten families, which in their order downward are Pieridtie, Nymplialidae, Agapetidae (Satyridae), Lim- nadidae {Danaidae), Libytheidae, Nen~eo- biidae (fVe7neobtu.i- lucfna), Riodinidae (Erycinidae - non European), Lycaenidae, Hesperiidae and Megathymidae (Megathy-
nus- an American type). The last five
families Grotc looks upon as an early and simultaneous offshoot from the Pieri-Hesper- idian stem, which lust culminated in the Pieridae, but on its way thereafter threw off the branch which included the remaining
families, in the order Libytheidae, Limna- didae and Agapetidae.
The scheme is based solely on the wing.
neuration and has its merits and demerits on this ground. The most striking innovation is the primary subdivision which ignores previous dichotomy by leaving the Hesperi- idae in conjunction with others ; a minor one is the separation, with family signification, of Nerneobius from the Riodinidae ; it shows the length to which one may go in discussing classification from a single standpoint.

An introduction, for the yo~nig student, to the names and something of the relationship and lives of our cominorier butterflies. Tlie siiilhor has selected for trealment the butter- flies, less than one hundred in number, which would he almof't surety met with by an. in- dustrious collector in a course of a year's or two year's work in our Northern States east of the Great Plains, and in Canada. While all the apparatus necessary tu identify these butterflies, in their earlier as well as perfect stage, is supplied, it is far from the author's purpose to treat them as if iheywereso many mere postage-stamps to be classified and ar- ranged in a cabinet. Hc has accordingly
added to the descriptions of the different spe- cies, their most obvious stages, some of the curious fucts concerning their periodicity and their habits of life.

In this ho.ok the aulhor has tried to present in untechnical hinguage the story of the life of one of our most conspicuous American
butterflies. At the same time, by inti-odnc- ing into the account of its anatomy, devel- opment. distribution, enemies: and seasonal changes some comparisons with the more 01- less dissimilar structure and life of other hut- terflics, and partic~ilfi.?ly of 0111- native forms, lie has endeavored to give, in some fashion and in brief space, a general ~CCOLIIIL of the lives of t!:e whole tribe. By using a single butterfly as a special Lext, one may discoume at pleasure of many: and in the limited field which our native butterflies cover, this meth- od has a certain advantage from its simplicity and directness.
