on and confirmatory of geological
changes. For these reasons and those
noted at the beginning, viz. -wide
distribution, terrestrial and conspicuous habits, numerical abundance, size, etc.
-the family and its distribution is of
high importance in a study of life zones in their relation to agriculture and of
faunal regions in their relation to,&meral science.
In conclusion, while the evidence
here presented is drawn largely from
personal experience, I wish to acknowl-
edge my indebtedness also to Messrs.
Scudder, IIenshaw, Beutenmiiller,
McNeilI, Harvey, and others through
data furnished by their publications,
collections, or notes of various kinds.
Owing to the total lack of data from
broad portions of the district it is mani- festly impossible to draw definite boun- daries at present for the faunal areas
of locust-distribution, and I am under
great obligations to Mr. Scudder for
permission to reproduce from his
faunal and climatal map those portions
and features most desirable for exami-
nation in this connection. The termi-
nology used, in a few cases now need-
ing revision, is, for convenience, the
same as that in my '' Notes on New.
England Acridiidae" (Psyche, Oct.
1894 to Dec. 18981, which contain
fuller details - seasonal, physiographi- cal, and geographical -of the distri-
bution of each species in New England
than can be given in the limits of this
sketch.
POSTSCRIPT ON FERUITA.
I have now before me mounted heads of
P. semtcrocea, which is the nearest to Smith's typical species I have seen, and of P. ver- besinae which is a typical Cockerellia.
The
actual palpal differences are as follows :- P. semicrocea.
Labial palpi with the first
joint about or hardly as long as the other three together; second longer than third or iuurth, which are about equal to one another. Maxillary palpi with the last three joints about equal to one another, and longer than first thrcc.
P. verSe&ae. Labial palpi with the first jointabout or over twice as long as the other three together; the other three subequal, but the third the shortest. Maxillary palpi with the first joint longest, the others about equal to one another, except that the second is shortest.
I must admit that there is more difference than I had supposed.

RECENT LITERATURE.
THREE entomological works of a more or
less popular character have been issued
recently and demand brief notice.
The readers of PSYCHE arc well acquainted with the careful observations of the habits of insects made by Mr. and Mrs. Peckham of Milwaukee. The State of Wisconsin has
now published a volume by them on the
instincts and habits of the solitary wasps. It is replete with interest and merits unquali- fied praise. The care, patienceand assiduity of theauthors in following the study of their little friends to the minutest details of their daily life and by night as well as by day, has Pwhs 8 32J-124 tprc.1903). htlp:tlpsyclircnlclub or@/S-321 html

enabled them to issue a work of the liveliest interest and importance. It should stir
many another to like industry. The habits of some twenty-two genera, often of several species under each, are studied, and even their individual idiusyncracies in many cases discovered and related. The illustrations add much to the value of the book, but the inspiring example of faithful work is its chief merit.
Mr. W. F. Kirby of the British Museum
has just issued a little hook, entitled Marvels of Ant Life (London, S. W. Partridge & Co). Although a compilation and so lacking the spirit of the work of an original observer, it is very well compiled, and in the short space of 174 pages covers sixteen chapters in the separate consideration of ants as architects, agriculturists, mushroom-growers, hunters, honey-pots; cattle-keepers, slaveholders, soldiers, etc., and culls from the abundant but widely scattered literature the best instances that can be given, and which are put together with skill. A general hibliog- raphy is appended, in which we miss Forel's extended paper on ants' nests, published in Zurich in 1893, and translated for the Smith- sonian Report of 1894.
Chancellor W. J. Holland's Butterfly Book (New York, Doubleday and McCIure Co.), is a "popular guide " to North American but- terflies, and has its special value from illus- trating in color some five hundred species with 750 figures. They are "three-color
prints," and are astonishingly accurate repro- ductions from nature to the minutest detail, surpassing the best chromolithographs and only occasionally falling short, where the registry is imperfect or the original speci- mens are not altogether satisfactory ; Nature, not a draughtsman, does the work for color as well as pattern. The work will add
greatly to the interest of the butterfly col- lector,for it is published at the extraordin- arily low price of three dollars, and figures most of our species north of Mexico. We
are disappointed to find the life histories ignored.
