They devour the flowers of golden rod and clover etc. with great zest.
All parties at Woods' Holl dnrin$lie sea- son insist upon it that they had no tennpera- ture atall approitching the freezingpoint. I described (Psyche ii, 189) a similar speci- men of A. rol;t~d/folin -published in Dec., 1878; and Brunner speaking of Lhe same
species in his Monogr. der Phaneropt. (p. 269) says one Pennsylvania specimen has violet tegmina. He also gives instances of similar variation in other Locustarians. Lewis gives an instance of the same peculiarity in Cyrto- å´filiylltw concavum- (Proc. Acad. nat. sc. Phi lad., 1883, 44). Samuel H. Scwider.
MCNEILL ON TKYXALISAK. -The Davcn-
port academy of natural sciences has just published, in an octavo pamphlet of 96
pages and six admirable plates, Prof. J. Mc- Neill's Revision of the Truxalinae of North America. It is one of the most important pieces of recent work done on North Ainesi- can Orthoptera by American entomologists; for tlie Tryxalinae have been one of our least known though richest groups. The class.ifi- cation is an independent one and does not follow very closely the features of Brunner's general outline for the Tryxalinne of the world given four years ago, and which con- tained a relatively small portion of the gen- era licre recognized by McNeill. Altogether 7.5 species are entered, referred to 31 genera, of which 11 are proposed as new. Only ten new species are described, which is an aston- ishingly small number for the country; since several new forms have been found in the East within recent years, and a great deal re- mains to be clone even here. A full figure, generally with considerable additional detail is given for every genus, but unfort~~nately the enlargement above nature is not indi- cated. The memoir places our small grass- hoppers on a very different basis from that on which they have hitherto stood, and the figures alone are a striking addition to our means of study and determination.
A GEXUS OF GRYLLIDAE HITHERTO UNRE-
CORDED FROM THE UNITED STATES. -I
have recently received from Mrs. Annie
Trumbull Slosson specimens obtained in
southern Florida of a new species of Mogo- siplist~is, which may be called M. sZussoui.- It differs from all known species in its long pronot~~in, which is considerably longer than broad, a little broader posteriorly than an- leriorlr, tlie lateral canthi rounded, the pos- terior margin truncate, straight, the lateral lobes equally rounded anteriorly and posten- orly; the first joint of tlic hind tarsi is elon- gate arid inucli more than twice as long as the hind tibia1 calcnriii; the ovipositor as long as the hind tibia and tarsi taken
together. The body is covered with gray
scales, beneath which the thorax is testaceous sirid the abdomen black; the central portion of the outer face of the hind femora is.also black; antennae castaneons. Length of
body, 9 7.5 mm; ovipositor, 5 mm. Bis-
cape Bay, Fla., under bark of trees.
Mrs. Slusson writes that they are silvery and iridescent in life, and very agile and were found wherever she tore off bark from fallen trees.
The genus has been heretofore known in
America only from Chili, 'the species from Cape St. Lucas Lower California referred here (Mogoplistes) by me belonging else- where. Sumuel H. Sriidder.

An inlroduction, for the young student, to the names and something of the relationship and lives of our commoner butterflies. The author has selected for treatment the hultw- flies, less rhan one hundred in number, which would be almost surely met with
by sin in-
duslrious collector in n course of a year's or two year's work in our Northern States east of the Great Plains, and in Canada. While a}\ the apparatus necessary to identify these butterflies, in their earlier as well its perfect stage, is supplied, it is far from the author's purpose to treat them as if they wereso many mere postage-stamps to he classified and ar- ranged in a cabinet. He has accordingly
added to the descriptions of the difl'crent spe- cies, their most obvious stages, some of the curious fi~cts concerning their periodicity and their habits of life.

A Chapter in Natural History for
the General Reader.
By SAMUEL 14. SCU~DRR. 186 pp. 16mo.
$1 .oo.
In this book the authoi has tried to present in untechnical language the story of the life of one of our most conspicuot~s Amci-ican biitlerflies. At the same time, by introduc- ing into the account of its anatomy, devel- opment, distribntion, enemies, and seasonal changes some comparisons with the more 01- less dissimilar structure and life of other hut- terflies, and particularly of our native forms, he has endeavored to give, in some fashion and in brief space, a
general account of the
lives of the whole tribe. By using" a single butterfly as a spcciiil text, one may discourse 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.
