[Vol. 11 
derson), with A. cinereus and A. vexans. Comparing this with A. triseriatus 
from New Jersey and New York, I thought it distinct, but Dr. Dyar doubts 
■whether it is worth naming as a race. Dr. Dyar observes, however, that in 
Montana also the triseriatus has the silvery lateral areas of mesonotum en¬ 
larged, while in Texas and Maryland they are narrow (typical triseriatus), 
and in Florida they are still more reduced. That is to say, the silvery areas 
are most developed in the arid west, and most reduced in the humid south. 
(17) Aedes vexans Meigen. Very common at lower levels, as along the eastern 
foothills and adjacent plains. Boulder, Camp Baldwin, Denver, Boone, 
Grand Junction, Rifle Range near Golden, Grand River 13 miles above Glen- 
wood Springs. It is a species of the Transition Zone with us, and is not found 
in the high mountains. In Wyoming, it was found at Basin, Box Elder Creek, 
Shell Creek and near Ten Sleep, being evidently as abundant as in Colorado. 
We also have a series of specimens of Aedes with black tarsi, which 
may represent two or three additional species; but as we have only 
females, and these mostly in bad condition, nothing definite can be 
said about them. 
I am indebted to Mr. F. Knab for assistance, but also and especially 
to Dr. H. G. Dyar, who has sent me many named specimens, and has 
examined all my puzzling forms. Had it not been for his kind assistance 
and advice, I could not have ventured to write this paper at the pres¬ 
ent time. 1

IMPORTANT FACTORS IN THE SPREAD AND CONTROL OF 
AMERICAN FOULBROOD 
By E. D Ball 
When the apiary inspection work of Wisconsin was recently placed 
in the writer’s charge, a hasty survey was made of the existing situa¬ 
tion in the state with reference to the occurrence of foulbrood and the 
method employed in inspection. 
The situation was found to be serious and the inspection methods 
used totally inadequate under the conditions existing. On extending 
the survey to other states somewhat similar conditions were found to 
exist and often similar methods of inspection were in vogue.

Culicid collection of the Colorado Agricultural College. This will be reported on 
at a later date.
