largely devoted to a consideration of the locust invasion of 1889-'92, and 
the history is interesting largely on account of the enormous numbers- 
of locusts which were destroyed by hand for the Government bonus. 
In some of the villages it was not unusual for 10,000 people to be at 
this work at once. Eggs were destroyed to the amount of 50,000 pounds 
in some districts, while the locusts themselves were killed in such enor- 
mous numbers that in a single district, that of Jhang, 1,500,000' 
pounds were destroyed. 
Technical Entomology at the Ohio Station..— Vol. I, No. 3, of the techni- 
cal series of the bulletins of the Ohio Agricultural Experiment Station r 
published April, 1893, is devoted to entomological and botanical papers. 
Mr. F. M. Webster, Entomologist to the station, contributes an article 
upon " Methods of Oviposition in the Tipulidse;" one on " A Dipterous 
Gallmaker and its Associates " (the gallmaker being described by Mr. 
John Martin as Lasioptera muhlenberghiw); and some general notes 
upon some species of Ohio Hymenoptera and Diptera heretofore unde- 
scribed. The Hymenopterous insects are described in a supplementary 
article by Mr. W. H. Ashmead. We have seen two editions of this 
bulletin, one published with a cover and with the plates separately 
printed upon good paper, while the other has the customary form. 
Virginia Station, Bulletin 1, New Series.— Various common injurious in- 
sects, with remedial measures for the same, are discussed by Prof. 
William B. Alwood in No. 1, vol. n, new series, of the Virginia Agricul- 
tural Experiment Station (Bulletin 24, January, 1892). The matter is 
elementary in character, dealing with well-known common insects, and 
includes also general directions for the preparation and application of 
the more important insecticides. Similar matter relating to fungus 
diseases and fungicides is also included. 
Colorado Station, Bulletin 24.— Prof. O. P. Gillette, in Bulletin 24 of the 
Colorado Station, July, 1893, presents a similar publication, dealing, 
however, with garden pests, such as the Cabbage Worm, Flea-beetles, and 
Onion Thrips. An account, with a new figure, is given of the Two- 
striped Flea-beetle (Systena tceniata Say), which is generally injurious to 
garden vegetables other than Cucurbitacese in Prof. Gillette's experience, 
and some valuable notes on an Onion Thrips which has been very inju- 
rious the present season in Colorado, and which, from specimens sent 
us, was determined by Mr. Pergande as probably Thrips striatus, but 
which Prof. Gillette thinks, from certain characters which he figures, 
may be a distinct species. Should this prove to be the case, he proposes.
