MOSQUITOES ( Culex spp.). 
Maryland J. A. Hyslop (September 15): In the southeastern part of 
Montgomery County mosquitoes have been more troublesome than 
any time in the past 10 years. 
E. N. Cory (September 22)': Mosquitoes are very abnormally 
abundant, especially Culex spp. 
Missouri L. Baseman (September 24): A small species of Culex has 
been unusually abundant and annoying through August and 
September. In the vicinity of Columbia it has been breeding 
abundantly in the streams and the adults have migrated into 
the city in swarms. The small size of the species has made 
it possible for it to pass through ordinary screens, and it 
is therefore particularly annoying at night. 
DOG- FLEAS ( Ctenocephalu s cenis Curt . ) 
CAT FLEAS ( Ctenocephalus f elis Bouche) 
General F. C. Bishopp (September 28): About the usual number of 
reports of house infestations of fleas have been received 
this season, but the trouble has continued later than 
ordinarily, probably owing to the warm weather. These reports 
emanate mainly from the North Atlantic States, with many from 
the vicinity of Washington, D. C. 
BLACK WIDOW ( Latrodectus mac tans Fab . ) 
Mississippi P.. F. Colmer (September 20): A child at Escatawpa was made 
quite sick from the bite of the hourglass spider.

STABLE FLY ( Stomoxys calcitrans L.) 
General F. C. Bishopp (September 2 - 12): Stable flies were observed 
to be a severe annoyance to all classes of livestock in the 
following localities: Tremonton, Ogden, Salt Lake City, Utah; 
Cheyenne Wells, Colorado; Hays, Ellsworth, Junction City, and 
Manhattan, Kans . In eastern Colorado and western Kansas the 
stock veve seen to be bunched fighting, stable anc orn flies 
from early morning to sundown, as a result of which there was 
reduced flesh and a sharp decline in milk flow.
