g^all revealed a small live white hymen- opterous larva, about z mm. in length
and apparently full grown, resting in
a small cell.
Old galls show irregular
small hollowed cavities and cells inside. In August, 1894, a perfect, and evidently freshly emerged, specimen of Limenilis
arthemis was caught at Nonquitt, Mass.,
in an exposed pliice close by the sea.

Dr. McCook is to be warmly congratulated on the successful issue of the third and final volume of his " Ainerican spiders and their spinning work," which has appeared four
years after the second volume.
The author
is more at home in his delineation of the out door worid than in systematic work,
with which this volume is mainly concerned, vet he has applied himself to this task with commendable zeal and success and describes 123 species and 30 genern.
Apparently (as
the table of'contents ciiriously shows) lie had intendedto carry his work beyond the " orb weaver>," but Ins coiiriige or his time gave out as he saw his work grow to portentous dimensions. We have to thank him for
thirty large and careful plates of spiders colored besides a mass of structiii'itl details ; they wiil greatlj facilitate future study. The price of the complete workis now justly advanced to $50.
Unhappily the title page
is marked 1893, though the preface is dated July 1894, and the volume was not issued until December, 1894.
Mr. and Mrs. Peckham have given us
(Trans. Wisc. ac:id., x) a new scriesof their ail~nii'able experiments with spiders in a piper on their visual powersandcolor sense; they " prove conclusively that Attidae see [heir prey (which consists of small insects) From a specimen which was bred
from the galls, Mr. Wm. H, Ashmead
determined the genus as above. It is
possible, however, that the Eurytoma
is not the gall-maker, but a parasite
of the latter.
when it is motionless, up to a distance of five inches; that they see insects in motion at much greater distances; and that they see each other distinctly up to at least twelve inches "; they are guided by sight rather than by smell. The experimenters are further 'I of the opinion that all the experiments taken together strongly indicate that spiders have the power of distinguishing colors."
Certainly the 'I U. C." [Upper California?] entomological society has done a unique
thing in issuing from Berkeley, Cal., as a Californian journal of entomology " The Entomologists' Daily Post Card" at $2.00 a year. A card of regulation size and color is printed on both sides in clear type, leav- ing a meague space for an address. The
number before us contains an editorial on Note taking, part of a list of species in Edwards's last catalogue of butterflies, and ti portion of a tabular key to the genera of Sy~phalldae.
It is a curious venture.
In a recent paper on the Siphonaptera
{Proc. Bost. soc. nut. hiat., xxvi, 312-3,51;) Dr. A. S. Packard gives an excellent resum6 of published observations on the embry-
ology, posteinbryouic history and anatomy and the adult structure of the fleas, adding new datsl from his own preparations and
numerous figures. He is led to regard
them as forming a distinct order standing nearer the Diptera than any other, -but
with many points of relationship to the
Coleoptcra.
Hansen gives in English (Ent. tidskr.,

Platypsylla-like insect infesting rats in Africa, and which had- previously been
studied only from dried material.
Saussure
in particular had published a long memoir upon it, founding upon it a new order,
Diploglossata, from its possessing, as he thought, a second labium. Hansen shows
that this does not exist (it is difficult to understand how the figures of Hansen and Sanssure can have been taken from the same kind of insect) and he concludes that
" Elemimerus belongs to the Orthoptera,
constituting a separate family very closely allied to the Forficulina." He shows from his dissections that the insect is vivipa- rous, bringing forth one jo~111.g at a time. THE SEVENTH VOLUME OF PSYCHE.
