June 1898.1 PSYCHE.
THREE NEW ALEURODIDAE FROM MEXICO.
BY T. D. A. COCKERELL, N. M. AGR. EXP. STA. The following three species, which are
more than usually interesting, were col- lected by Prof. C. 14. T. Townsend, and sent to me by Dr. L. 0. Howard.
In the genus
Aleurodes, the best characters are derived from the pupa; and, in fact, the adults of very many species are still unknown. In
Aleur'odicus, on the other hand, we get our specific characters from the imago, and the pupae are all much alike.
That this sort of
difference should obtain between two so
nearly allied genera, is a matter of much interest.
Aleurodicws irsdesceas, n. sp. -~g-r& with A. asar~wzis in having some blackish colora- tion at the forking of the wing-vein, but differs in having the body and legs a deep chrome yellow, and the eyes not divided. Length of anterior wing 2 mm. ; wing's no- ticeably iridescent; a blackish line on the costa. Pupae along' the midrib of the leaf, as in Aleurodicus å´pulvinuf (Maskell, as Aleurodes), surrounded by abundant cottony secretion.
Pupae dark grey or plumbeous,
varying to brownish, structural characters as usual in the genus. Vasiform orifice
semicircular ; operc~~lum very broad, broadly truncate at end.
Four large round orifices
on each side of the abdomen, some distance from the margin, but not nearly so large as Maskell figures for $zclvinata; four very much smaller orifices in the caudal region, laterad of the vasiforn~ orifice, the two liind- most nearer to each other than are the
anterior, ones ; two of the large orifices at the cephalic end, and also four small ones as inpulvinatu, but they are very minute. Hub.-.Ocean beach between El Faro and
San Pedro, Tabasco, Mexico, June 12, 1897, on 'I Jicaco," a bush with large leaves grow- ing on the sand fiats, (Townsend.) Div.
Ent. 7824.
AUurodes ??ai~abi/is, n. sp.- Pupa (late larva?) 18 mm. long, after boiling transparent and colorless!;, except some brown stains in the thoracic region. Mouth-parts distinct and well-formed ; rostial loop short ; legs present, very stout, with small hooked claws. Form oblong, quite elongate, with a border densely dotted with round glands; anteriorly this border is very narrow, and at the extreme hind end it ceases, but all along the sides it is extremely bi oad. The cephalic portion of the insect, the hind end, and the lateral mar- gins within the border, are also densely dotted with glands. Abdomen distinclly segmented, but the segmentation does not extend to the border. On each side of the abdomen are
four curious large glandular procesiscb, of the type of those in A. Jiohesii Mask. Lingua trowel-shaped, extending considerably beyond the broad operculum; at each side of the base or the lingua is an angular prominence. The general type of these parts is that of A. fnlvinata Mask., but while the lingua is equally long, it is in our insect gently bowed out at the sides; and the two bristles at the end of the lingua in mirabilis are not nearly 60 long ass in puluinata.
Externally, the insect appears as a large mass (5 to 10 mm. long) of snow white cot- tony tufts, irregularly disposed, from the midst of which spring many very long
curved white threads. The pupa itself is en- tirely covered.
Hub.-Boca del Usumacinta, Tabasco, Mex-
ico, July 8, 1897, on "Laurel," which is not our plant of that name (Townsend.) Div.
Ent., 7984. This remarkable insect resembles Alenrodicus several respects; when all its stages are known it will probably be referred to a new genue.
AZswodes v&sonioides, n. sp.- Pupa of an intense black, even after boiling. At one

end, far apart from each other, are two small roiind o~ifices. Margin minutely headed with brown. The pupa has the usual oval form, and is hardly over imm. long, minutely
transversely ribbed down the middle of the back; with twelve broad ribbon-like rays of glassy secretion, not much shorter than itself. These rays are of a bright lemon yellow, except at their ends, which are white. Lar- val skin attached to dorsum of pupa.
Hab. - Frontera, Tabasco, Mexico, on
leaves of a tree having small white flowers. (Townsend.) Div. Ent. 7669. Allied to
A, stellata. The insect looks like a coccid of the genus Yinbonia.

PACKARD'S NEW MANUAL.
DR. PACKARD'S Guide to the study of in-
sects has passed through many editions and has been for a long period the most successful and serviceable manual the American ento- mologist has had ; the classification of insects was its foundation. The learned author now comes forward with a Text book,* constructed on a totally different basis ; there is scarcely a word of classification in it, but only the facts forming the basis of classification: the external and internal structure, the emhry- ology, and the metamorphic changes ; that is, it is morphologic instead of taxonomic, to serve the present needs. It is the book for the day and is sure to command atten- tion and come into general use. Numerous special bibliographies scattered throughout the book will prove of great service; they should, however, have been listed in the table of contents or separately, and the index is not so full as one could wish. There *A text-book of entomology, including the anatomy, physiology, embryology and metamorphoses of insects, for me in a~ricnltural and teclmicd sclmols and colleges, as well as by the working entomologist; by A. S. Packard. 174-729 pp., 654 figs. New York. The Macmillan Co. 1898. $4.50.
is too little room in our small journal for the fuller notice it deserves, hut we strongly advise its purchase by every entomologist, as a marvellous storehouse of facts, where the latest researches find a place.
JOSEPH ALBERT LINTNER.
A DISPATCH from Rome, Italy, announcing
the death of the state entomologist of New York, was published in the newspapers on the very day we received his twelfth Report on the insects of New York, a volume of more than a hundred and fifty pages, and, like all of his papers, filled with the proof of pains- taking conscientious labor. Let us hope
his successor will prove as diligent and faithful.
PROCEEDINGS OF THE CLUB.
8 APRIL, 1898.
The 201st meeting of the
club was held at 156 Brattle St., the President in the chair; Mr. J. W. Folsom was chosen secretary pro tern.
Mr. S. H. Scudder exhibited the North
American species of Scudderiae and briefly summarized the result of his recent studies upon that group. Thirteen species are
known, of which one necessitates a new
genus, Platylyra. All the eleven species of Scudderia are closely similar to each other, with a few striking exceptions, and fall into four groups, based especially upon the struc- ture of the male genitalia, of which drawings were shown. The species septentrionalis and forcipata are remarkably peculiar in respect to their accessory genital organs. Five
species occur in New England, of which
furcatd is found across the continent, and texensis ranges as far west as Utah.
Mr. J. W. Folsom said that nothing had
hitherto been published concerning the
Collembola of Japan, but showed specimens and figures of three new species from Tokyo.
