BENJAMIN COOKE, for several years Presi- dent of the Northern entomological society and later Vice President of the Lancashire and Cheshire entomological society, died nt Southparti England, 4 Feb. 1883, aged 66 years.
COUNT H. zu SOLMS-LAUBACH has lately
published a pamphlet on the origin, domes- tication and cultivation of the fig-tree, which contains much of interest on the subject of caprification. An abstract of the pamphlet is given in New Remedies for April 1883. REV. HENRY C. McCook, of Philadelphia,
is engaged upo,n an illustrated book on "Am- erican spiders and their spinning work," and hopes to have a volume on the "Industry
and habits of orbweavers" ready by midsiirn- mer.- Sci~ftre, 33 March 1883, v. I, p. 207- THE PAPER by Prof. F. H. Snow in PSY-
CUE (vol. 3, no. 98) on Trogodem tarsale is noticed in the American naturalistfor Feb. 1883 (p. 199), where it is stated that this spe- cies is "the most common museum pest in
this country," and that it is by far the most dangerous enemy to collections of insects in . 'Washington, D. C.
PROP. XAVER LANDBRER writes, in the
Deutsch-Amerikanische AjotJieker-Zeitang for 1 March 1883, that "the largest and heav- iest grasshoppers are sought out in Arabia, Egypt, etc. The wings, feet, heads, etc. are torn off and the remaining fleehy part put in vinegar and used as pickles. I11 Abyssinia I had such sour grasshoppers prepared with aromatic herbs, set before me, and they tast- ed finely and would be eaten with appetite by all who did not know what they really had before them."
PROF. F, W. MAEKLIN died January 8th of
this year at Helsingfors, Finland, at the age of 61 years. He was known to American
coleopterists by his papers on St~o1zgyZiwn and Stdira, and by his descriptions of a large number of coleoptera (mostly Sfaphy- Zinidae) from the extreme north-western
portions of our country. One of his 'earlier and little known papers, a dissertation on re- presentative ( vikarierande ) forms among northern coleoptera (published in the Swedish language, Helsingfors, 1855) is quite interest- ing to American coleopteriets, and was trans- lated into German by I?. von Sacken in the Stettiner Entomoiogische Zeitung for 1857.- Amer. natiralist, April 1883, v. 17, p. 424. WE ARE indebted to Mr. G. Barrtcelli, of Holden, Mo., for several numeros of his
'A Silk-culture directory," and for two nos. of the "American silk and fruit culturist" containing articles by him. Mr. Barricelii evidently has a good practical knowledge of silk-raising, notwithstanding some of the cu- rious statements, from a purely scientific standpoint, made in his pnpers. Hie "Silk-

culture directory" is still more curious from a typographical and literary standpoint. Altho we think silk-raising will not become a great industry in this country for years, on account of the high price of labor, yet agita- tion in the interest of silkworm-raising may do good. In families comprising a number of otherwise unenlployed persons the
small
profits to be derived from the rearing of a few thousand silk-worms may be worth the labor.
THE Dezitsch-Amerikanische A'pothcker-
Zeititftg, for I March 1883, gives M. Serpin's mode of making insect powder from tar.
Lb The process depends upon converting gas- tar from fluid into solid condition, but taking care that the tar retains all the efficacious properties which it had in liquid form.
The
conversion is brought about by careful heat- ing of the tar over a moderate coke or coal fire to zo9-40å C. A proper quantity of lime or finely powdered gypsum is mixed with
it. A pulverisable mass is now obtained, which is rubbed through a sieve, and after completely cooling, the powder is mixed
with ammonic sulphate, ferrous sulphate, bits of glass, and sodic sulphate, all in pul- verized condition."
