G. B. Wagner ‘states that reports are being received daily that 
heavy infestations of grain are developing throughout the entire South—_ 
west. These reports generally concern l- to 3 pee wheat stored in 
elevators. The lesser grain borer (Rhizopertha dominica Fab, ) seems to 
be increasing in grain stored for longer periods - than usual, and in some 
such grain it is doing as much damage as the better known and widely — 
distributed rice weevil oSlgeloes aa: oryza L. ye ' 
Exeminations made during November by T. A. Brindley at Moscow, 
Idaho, indicate that the mortality among hibernating pea weevils (Bru- 
chus pisorum L.) is very light. These examinations will continue 
throughout the winter. In experiments conducted during the past grow- 
ing season to cetermine the value of dusting with calcium arsenate, Mr. 
Briniley has found that 30 percent. of the seeds were infested at the 
end of the experiment in the dusted plot, as compared with &6 percent 
in the check plot. In another experiment, conducted under cages, there- 
by eliminating the early infestation which usually occurs in the open 
field, it was found that only 0.2 percent of the seeds became infested 
on the dusted vines, as compared with 90.6 percent infested on the check 
vines. 
A. O. Larson and F, Hinman report that a check made on the peas 
fumigated throughout the Willamette Valley indicates tnat the results 
were very satisfactory. Chloropicrin was the fumigant most often used, 
100 percent of the weevils being: killed in three fumigations and 97.5 
percent in a fourth. . 
The Dried Fruit Association of California estimated several years 
ago that the annual cost of fumigation as employed by members of the 
Association was about $100,000. Perez Simmons states that the technol—- 
ogist for one large firm of packers of dried fruits in California says 
that at one plant of his company the cost of fumigation is about $2,000 
per month. 
IDENTIFICATION AND CLASSIFICATION OF INSECTS 
A. G. Boving has received, through the National Museum, from Paul 
N. Musgrave, Fairmont, W. Va., two very rare larvae representing the 
immature stages of the water beetle Ancyronyx variegatus Germ. 
Doctor Boving has identified for C. R. Crosby, of Cornell Univer- 
sity, larval specimens of a weevil which, from comparison with deter- 
mined European material in the National esta collection, appear to 
be Gtiorhynchus ligustici L. These specimens were found in destructive 
numbers on alfalfa roots, in Iswego County, N. Y. Further confirmation ~ 
of this identification of ‘the larval specimens is indicated from the — 
fact that adults of this same species, collected in the same vicinity, 
were identified last year by L..L. Buchanan, of this division, as we
