J. C. Bridwell, a graduate of. the Towa Tented Colleper ga 
been appointed "Ss Specialist in. Bruchidae and: their parasites," with head~ 
Quarters at Honolulu.” The increased ; ~lantings of the introduced alga- 
roba tree throughout the Hawaiian. Islands has led to the developzent, “~~ 
during the rast few yeats, of the nanufacture of a valuable stock feed 
fron. the seed rods of this tres. Chemical analyses prove that the al= ~ 
garoba beadn weevil (Bruc chus prosopis) which was introduced into the Is- ~ 
lands along with its host plant, is respotsibbé for a large loss¥in the 
protein content ‘of the feed, . Because of the eauatle climate and the ri- 
pening of successive ‘crop s of pods throughout the year, ‘the infestation 
of the pods on the tree te eeoe and. probably will not yield to artifi- 
cial control measures. Several parasites already present in Hawaii may- 
be acconplishing all that parasites can. in limiting: the free t caused 
by the weevil. ae 
There occur in the southwestern United States a considerable number . 
of bruchids that attack the.native mesquite .(the Hawaiian algaroba, Pro~* ~ 
sopis julifbota,” isa nésaquite). Mr ,. Bridwell will make a study of: 
these brucnids-and their parasites with a view to relieving the Hawaiian 
Situation >y introducing parasites which.give ;romise of usefulness.” ; 
Mr. TBrtdwell has hud a wide experience in entonology, tiscte a he 
nas ~ublisned little, his latest paper being on Hawaiian bruchids and 
ie parasites, publisned in the Proceedings of the Hawaiian Botomot6~- 
ficalusouiety for 1918. Aas assistant entomologist of the Hawaiian. 
Board of Agriculture and Forestry, and as member of the Fullaway-Brid- 
well expedition sent by that Board to. Africh in search of parasites of 
fruit flies, Mr. Bridwell becane thoroughly faniliar with the process 
of rearing and caring for parasites. Recently Mr. Bridwell has béen a 
Specialist in insects at the Bishop Museum, in-Honolulu: . He has a large 
private collection of Hymenoptera, in which he -has Speciation) and a 
library.
