females of TriLhemis umbrafa in which one of the latter showed the secondary characters of the male. This led to ageneral discussion of cases in which either sex tends to assume the secondary characters of the other. Cases were mentioned in the Orthoptera, Cole-
optera and especially Lepidoptera.

An introduction, 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 butter- flies, less t,han one hundred in number, which would be almost surely 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 to identify these butterflies, in their earlier as well as perfect stage, is supplied, it is far from the author's puipose 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 different spe- cies, their most obvious stapes, some of the curious facts concerningthe& periodicity and their habits of life.
Scudder's The Life of a Butterfly.
A Chapter in Natural History for
the General Reader.
By SAMUEL H. SCUDDER. 186 pp. 16mo.
$1.00.
In this book the author has tried to present in untechnical language the story of the life of one of our most conspicuous American
butterflies. At the same time, by introduc- ing into the account of its anatomy, devel- opment, distribution, enemies, and seasonal changes some comparisons with the more or less dissimilar structure and life of other but- terflies, and particularly of our native forms, he has endeavored to give, in some fashion and in brief s ace a general account of the lives of the wholetribe. By using a single butterfly as a special 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.
