September 1893.1 Ps~cHx!?. 525
Mr. J.M. Aldrich, lately of Lawrence, Kan- sas and formerly entomologist to the experi- ment station at Brookings, S. Dakota, has been appointed entomologist to the experi- ment station at Moscow, Idaho.
Rubsaamen has published in the Berliner
entomologische zeitschrift (v. 37) a system- atic study of the Cecidomyidae of the Berlin museum, accompanied by 14 plates illus-
trating the structure of the wings, abdominal appendages, antennae, head, pupae and
*breast bone". They are divided into 2 sub- families and 23 genera, 4 of them new; 80 species are considered.
The first (double) number of the same
journal for 1893 is given up to the first instal- nient of a description by Karsch of the insects of Adeli, West Africa, consisting of the Apterygota, Odonata, Orthoptera saltatoria, and butterflies.
Aldrich publishes in the first part of vol. 2 of the Kansas university quarterly a re- vision of the N. American species of the dipteran genera Dolichopus and Hygroceleu- thus, 81 of the former (21 new) and 5 of the latter (I new). An excellent plate is added, especially devoted to antennae.
Moore's Lepidoptera Indica (part 15) is
still occupied with the Satyrinae; the early stages of only one species are figured, but the wet-season and dry season broods of eight species are distinguished.
PROCEEDINGS OF SOCIETIES.
CAMBRIDGE ENTOMOLOGICAL CLUB.
14 April, 1893.- The 178th meeting was
held at 156 Brattle St., Mr. S. Henshaw in the chair. Mr. H. A. Morgan of Baton
Rouge, La., was elected to active member- ship.
Mr. S. H. Scudder showed the fossil fly
from Florissant which he had described under the name of Mycefo$kaetus iiitermedhtf
Owing to a suggestion of M, Ch. Brongniart of Paris he had re-examined the specimen and found that he had been mistaken in re- ferring it to the Mycetophilidae, since the antennae are brief and not very long as he had supposed and the relative stoutness of the legs showed that notwithstanding its ap- parently spurred tibiae and small size it belonged to the neighboring family
Bibionidae and to the genus Penthetria, an existing genus already well-known in tertiary deposits.
Mr. A. G. Mayer remarked on the
lepidopterous fauna of the Bahamas which he had just visited. All the species found by him, with the exception of a Utetheisa, are strong fliers, as the weak fliers are blown off shore by the trade winds. Anosia $!ex- @$us was seen as well as species of Pieridae, Heliconidae and Hesperidae. The fauna and flora seem derived largely from the United States, though in part from South America. Mr. Scudder called attention to a recent paper by Hampson on strid~ilation in
Lepidoptera and said he had heard a clicking sound from Polygonia faunus on Mt. Wash- ington, N. H. Mr. Mayer said he had
observed the same in P. interrogationis. Mr. A. P. Morse exhibited specimens of
the pupae and imagines of a moth found
feeding on woolens; also the opened egg
cocoon of a spider which in nature bore a considerable resemblance to an oak apple. Dr. H. S. Pratt stated that he had recently been engaged in studying the embryology of the sheep tick. The head is developed in the embryo but is concealed in the larva by two imaginal disks, which are formed by
invagination on the dorsal side at some dis- tance from the anterior end; they remain latent during the larval state and in the pupa are developed into the head. The larva
bears considerable resemblance to that of the fly.

Scudder's Brief Guide to the Com-
moner Butterflies.
By SAMUEL H. SCUDDER, author of "But-
terflies of the Eastern United States and Canada,"etcd xi + 206 pp. 12mo. $1.25.
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 than one hundred in number, which would be almost surely met with by an in- dustrious collector in a course of a year's 01- 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 were so 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 curious facts concerning their periodicity and their habits of life. A short introduction to the study of butterflies in general is prefixed to the work, and is followed by a brief account of the principal literature of the subject. Scudder's The Life of a Butterfly.
A Chapter in Natural History for
the General Reader.
By SAMUEL H. SCUDDER. 186 pp. 16mo.
$1 .oo.
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 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 many : and in the limited field which our native butterflies cover, this meth- od has a certain advantage from its simplicity and directness.
