on EB. elutella by E. M. Livingstone as follows: "The first pupation of 
the second brood of moths occurred September 20. Most of the second- 
generation larvae were one-half to two-thirds grown. * * * all eggs were 
laid between 4 p.m. and 19 p.m. The peak of the egg laying occurred be-— 
tween 6 p.m. and 7 p.m."

One pound of HCN per car fails to kill rice and granary weevils.—— 
According to George B. Wagner, Kansas City, Mo., "The mills and rail- 
road companies of the Southwest have been bothered with insects back 
of the grain lining in box cars infesting flour in transit. Fumiga— 
tion of the box cars was started September 13. Approximately 100 cars 
have been fumigated before being loaded with flour, using 1 pound of liquid 
hydrocyanic acid per car. Results of the fumigation to date indicate 
that this dosage is not enough, since on the average we can only obtain 
a kill of 48.75 per cent of granary and rice weevils and 86.75 per cent 
of the other insects. Other insects included Oryzaephilus surinamen— 
sis L., Cryptolestes pusillus Schoen., Tenebroides mauritanicus L., 
Cryptolestes ferrugineus Steph., Tribolium confusum Duv., Tribolium 
ferrugineum Fab., and Rhizopertha dominica Fab." 

Volunteer peas prove to be a source of pea-weeyil infestation.— 
Tom Brindley, Moscow, Idaho, has studied the effect of volunteer peas 
(those that come up from seeds lost during harvesting) on the weevil pop- 
ulations. His data show that "the weevils readily find these peas at: 
about the time they bloom. They are very heavily infested. In any con- 
trol program much attention must be given to the elimination of these 
peas. Observations show that fields that are disked early .in the fall, 
or fields on which sheep have been permitted to pasture, have very few. 
volunteers the following season. This, of course, is from only one sea— 
son's observations."
