ionidae falls away and I am still on the search for possiblc ancestors for my Pilpilionides. And this leads me to believe that photo- graphic methods are probably the only reli- able ones for reproducing neuralion, and that my efforts for the introduction of photo- graphy in the illustration of lepidoptera, commenced first more than twenty years
ago, as recently kindly remembered by Mr. Moffat in the pages of the Canadian Ento- mologist, were efforts bringing fruit. Let me flatter myself also that my efforts to vitalize the study of the wings of the butter- flies will not have been in vain, nay, more, that they may even be ultimately crowned by the restoration of Papiliu.

HAYWARD ON BEMBIDIUM.
IN THE Transactions of the American en-
toinolog'ical society, vol. 24, p. 32-143 (Feb,- May, 1897), Mr. Roland Hayward publishes a valuable monograph on the species of
Bembidium of America, north of Mexico.
One hundred and twenty-four species are
recognized as valid, twenty-four are de- scribed as new, and two new names are pro- posed for preoccupied names. The original descriptions of thirteen species described by Chaudoir, Manncrhcirn, and Motschulsky,
as yet unidentified, are reprinted in an appendix. In 1857, Pi". Leconte found
Duval's grouping of the European species of Bembidium not at all applicable to the
species of our fauna, and published (Proc. acad. nat. sci. Phila., p. 2-6) a catalogue of the species found in the United States and contiguous northern regions, together with a tabular separation of the species into groups. Leconte's keen perception of the true iiffin- iliea of species, evident in all his work, is well shown here, as Mr. Hayward, after a thorough study of a large rtmounf of mate- rial, proposes but a slight modification of Leconte's order of arrangement of the groups, suppresses one of his groups, and erects but a single new one. Mr. Hayward's analytical tables are well prepared, and, though useful, should be relied upon only in connection with the descriptions ; each species is fully described. The synonymy is carefully worked out: in most cases by direct comparison with the types ; an adequate bibliography is given, and the habitat of each species is noted in more detail than usual in works relating to our fauna.

An introduction, for the youngstudent, to the names and something of the relationship and livcs of our commoner butterflies. The author has selected for treatment the butter- flies, less than 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
purpose to treat them as if they wereso many mere postage-stamps to be classified nnd ar- ranged in a cabinet. Hc has accordingly
added to the descriptions of the different spe- cies, their most obvious stages, some of the curious facts concerning their periodicity and their habits of life.

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, dcvel- op~ncnt, 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 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 of inany: and in the limited field which our native butterflies cover, ihis meth- od has a certain advantage from its simplicity and directness.
