380 JOLRXAL OF ECOXOMIC ENTOMOLOGY [Vol. 1 and the 30th of :JIay it rained very hard, and on June 2d a check row of beans was examined and 207 red spiders wcre f<und on 13 leayes. On June 8th, after a week of daily rain, vcr~' fpw rpd spidpJ's "'pre to be seen. From this it appears that one 01' two rains wiJl not seri- ously injure the red spidel', but that continued rains fOt' several days are fatal to a large proportion of the insects. A LIST OF PARASITES KNOWN TO ATTACK AMERICAN RHYNCHOPHORA Downloaded from By W. DWIGHT PIERCE, Burean of Entomology, U. S. Dept. of A{j'rieu1ture As the weevils become more important economically there will be a growing necessity of understanding the parasites which ::nay check their injuries. A preliminary list of these parasites was published by the writer in Bulletin 73 of the Bureau of Entomology, without, http://jee.oxfordjournals.org/ however, indicating the sources of the records. Since that time many other important records have been added, and if all the species bred by the boll weevil investigation force were determined, double the number of additions could be included. The credit for parasite breeding records made at the boll weevil laboratory during 1907 and 1908 must be shared equally by the writer with :Jlessrs. R. A. Cushman and C. E. Hood. by guest on June 9, 2016 Notice of omissions is very earnestly requested. Fungi.
