of the head and pronoturn.
The wings
are usually yellow, often pale yellowish- white, sometimes orange or even red.
This is our rarest Occ1ipocline, and
the only one which I have not met in
the field in an extended experience in
collecting the New England locusts.
Reported from Norway, Me., by Smith,
and eastern Mass. by Scudder, nothing
is recorded concerning the date of cap-
ture or character of the locality where
found. It probably occurs, however,
in localities similar to those frequented by its congener. Numerous specimens
which I refer to this species were found by Mr. S. W. Denton in Ohio and
Illinois in midsummer.

Harris states that the larva lives on lichens growing on rocks.
Meishcimcr found them on lichens on the
trunks of hickory trees.
The full grown larvae occurred to me not uncommonly on an old stone fence at Jeffer- son Highlands, N. H. in the middle of June. Eggs were obtained a month later.
Eps-. Laid singly, adherent. Oblately
spheroidal, the lower half more flattened than the upper, both well rounded; a little elongated in one diameter, but only just per- ceptible. No true retic~ilations, but the sur- face is distinctly flattened in hexagonal areas, the edges of which are not defined into eleva- tubercles, normal, subprimaries absent. On thc thorax seta ii b is distinctly present, not weak ; i a. i b and ii a in line, rather remote. The head is blackish with sutures inky black. Length of larva 1. j mm.
Mature larva. Gray, dotted with pale
green with thin, very long, blackish hairs. Head bilobed, clypeus large, lower part pale; brown with two pale green, narrow, trans- verse, irregular lines; hairs short, white ; width 1.5 mm. Body rather flattened,
brown gray with many irregularly triangu- lar, transversely streaked patches; a gctnin- ate, rather large, anterior segmenlal, dorsal, pale yellow one on joints 5 to 11 is most dis- tinct. the others whitish, smaller and con- fused. Legs pale, two setae on the obscurely corneous plate. I have described the other setae.

The spottings seem to represent broken
ad-dorsal, lateral, suprastigmatal and sub- stigmata1 lines. The coloration closely re- sembles the lichen covered rocks, so that the tions, but form simple angles of the surface, larvae are only seen on close examination.

THE BUTTERFLIES OF HSLDESHESM.
OUR countryman, 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 I~Iildesheim and is by Mr. Grote himself, as four previous numbers have been (44 pp., 4 PI.) 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 classificiitions in vogue, if any can be called in vogue in this time of flux.
butterflies are first divided into two great qroups, the Parnassi-Papilionidae 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 Pieridae, Nymphalidae, Agapetidae (Satyridae), Lim- nadidae (Danaidae), Libytheidae, Nemeo-
biidae (Nemeobius lucina), Riodinidae
(Erycinidae - non European), Lycaenidae, Hesperiidae and Megathymidae (Megatliy-
mns-an American type). The last five
families Grotc looks upon as an early and sin~ulta.neous offshoot from the Pieri-Hesper- idian stem, which last 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-
neumtion 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 Nemeobius from the Riodinidae; it shows
the length to which one may go in discussing classification from a single standpoint. Guide to the Genera and Classification of the Orthoptera of North America north of Mexico. By SAMUEL H.
