and the 30tli of ]\Iay it rained very hard, and on June 2d a check 

 row of beans was examined and 207 red spiders were found on 13 

 leaves. 



On June 8th, after a week of daily rain, very few red spiders were 

 to be seen. From this it appears that one or two rains will not seri- 

 ously injure the red spider, but that continued rains for several days 

 are fntal to a large proportion of the insects. 



A LIST OF PARASITES KNOWN TO ATTACK AMERICAN 

 RHYNCHOPHORA 



By W. DwiGHT PiEECE, Bureau of Entomology, U. S. Dept. of Agriculture 



As the weevils become more important economically there will be 

 a growing necessity of understanding the parasites which may check 

 their injuries. A preliminary list of these parasites was published 

 by the writer in Bulletin 73 of the Bureau of Entomologj^ without, 

 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 INIessrs. R. A. Cushnian and C. E. Hood. 



Notice of omissions is very earnestly requested. 



Fungi. 



Asperoilliis sp. is recorded by Hunter and Hinds (1904. 105) as bred from 



Antlionovius grandis Boh., at Victoria, Texas. 

 Coydyceps sp. was found attacking the boll weevil (Anthonoinus grandis) 



at San Juan AUende, Mexico (Townsend 1895a). 

 Empusa (EntomopMJiora) sphaerosperma attacks the clover-leaf weevil, 



Phyto7iomus punctatus Fab., abundantly at Annapolis Junction, Md. 



(Johnson 1898). 

 Entomophthora phyt&nomi attacks the same weevil in Ontario (Fletcher 



1900). 

 Isaria tomicii Lugger is recorded as killing adult Platypus compositus 



Say (Hopkins 1896). 

 Sporotrichum glohuliferum was bred from the imbricated snout beetle, 



Epicaerus imbricatus Say, by Chittenden (1900b. 31). 



Acarina. 

 Tarsonemidae. 



Pediculfiides sp. (nee. ventricosus Newp. mis-spelled ventriculosns) is a 

 common parasite of Authonomus grandis Boh. (Rangel 1901a, b) and
