Recent Publications.—Mr. Lawrence Bruner has lately pub- 
lished? an interesting and extended account of the insects affecting 
the sugar-beet. A number of new original illustrations appear in con- 
nection with it. Full reports of the recent meetings of economic 
entomologists at Champaign, Illinois, have appeared in late issues of 
Lnsect Life (VIIL, Nos. 5 and 6). Mr. S. H. Scudder has begun, in 
Psyche, the publication of a series of interesting letters between Harris, 
Say, and Pickering. Prof. A. J. Cook and Mr. G. C. Davis have 
lately published, in Bulletin 73 of the Michigan Agricultural Col- 
lege, descriptions of seven new species of hymenopterous parasites. 
Professor Cook also has a number of interesting entomological 
articles in the Report of the Michigan State Board of Agriculture for 
1890. Mr. C. H. Tyler Townsend has published several important 
papers concerning Diptera in the Proceedings of the Entomological 
Society of Washington. In the same Proceedings Mr. E. A. 
Schwarz has also printed a number of interesting papers on Coleoptera 
and general entomology. An excellent account of the facilities for 
investigating injurious insects possessed by American experiment 
Stations, together with a summary of the results so far obtained by the 
Station entomologists, appeared recently in the Journa? für Landwirth- 
schaft. It was prepared by Prof. M. Wilckens, of Wien, who some 
months ago passed through America, studying the systems of our 
agricultural colleges and experiment stations. Article XL, Vol. 
UI., of the Bulletin of the Illinois State Laboratory of Natural His- ~ 
tory is by Prof. C. P. Gillette, and consists of descriptions of a large 
number of new species of Cynipid in the laboratory collection. It is 
illustrated by a good plate. 
-Osborn on Pediculi and Mallophaga.—Prof. Herbert Osborn, 
of the Iowa Agricultural College, has lately published as Bulletin No. 
7 of the United States Division of Entomology an excellent dis- 
cussion of ‘The Pediculi and Mallophaga Affecting Man and the 
Lower Animals.” One new genus—Hematopinoides—and five new 
Species of Pediculi are described ; while a single species is also added 
to the known Mallophaga. The bulletin is well illustrated, many of 
the figures being new, and forms a very acceptable contribution to our 
Knowledge of these little-known groups.
