THE TRLWGLE SPIDER IM CALIFORNIA.-
On November 5, 1898, Professor 0. P. Jenkins of this University (Stanford) found a single triangle spider {Hy@iotes sp.) on its web in a cedar tree near the University.
The web
was nine inches long and six inches wide at its base. It had four radii and twenty-two cross threads. At about the same time Dr. Jenkins found a few other webs but was
unable to capture any more of the spiders. The spider seems to be the familiar triangle spider of the East, but differs in a number of minor characters and rather markedly in size. Until more specimens are obtained, however, (and in the two years since finding the first no others have been seen) the specific iden- tity of this Hyptiotes cannot be certainly determined.

An introduction, for the young ~tiideut, to the names and something of the relationship 2nd lives of our commoner butterflies. The author has selected for treatment the butter- flies, less than one hundred in number, which would he almost surely met with by an in- dustrions 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 asperfect stage, is supplied, it is far from the author's put pose to treat them as if they wereso many mere postage-stamps to be classified and ar- ranged in a cabinet. He has accordingly
added to the descriptions of the different spe- cies, their most obvious stages, some of the cuvioi~; facts concerningtheir 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 untechnica! lnngnage 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 chiinges 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 space, a general account of the lives of the whole tribe. By using a single butterfly as a special text, one may discourse at pleasure ofniany: and in the limited field which our nntive butterflies cover, this 1net11- od has a certinn advnntnge from its simplicity and directness.
