A weevil, Pseudocneorrhinus setosus Roelfs, a native of Janan, was 
first collected in North America, so far as our records show, on August 
3, 1914, in a nursery at Riverton, 3Sf. J. In 1920 this species was found in 
a nursery in New Haven, Conn., where it was feeding on "burr marigold (Bidcns 
sp.).^ It was again collected in New Haven in 1921, 1922, arid 1923. In 
1931 it completely stripped a hedge of California privet and a row of Japa- 
nese barberry bushes in that city, and this year did considerable damage 
to these plants. 
The white spruce sawfly ( Di-prion polytomum Htg. ), which caused rather 
severe defoliation of white spruce in the Gaspe' peninsula of Canada for the 
past three or four years, was discovered at Bar Harbor, Maine, this year. 
MOSQUITOES 
An unprecedented outbreak of the mosquito Fsorophora columbiae P. & K. 
occurred during September in the Everglades section of Eade County, Fla. 
On September 4, following a northwest wind which blew for several days, 
enormous numbers of these large mosquitoes were observed. By the 5th they 
had increased to unprecedented numbers, and by evening of that day the 
buzzing was as loud as that of a swarm of bees. During the night live- 
stock couLd be heard running and thrashing in the underbrush, and on the 
morning of September 6, dead animals were found throughout the section. 
The recorded mortality was 30 head of cattle, 3 horses, 1 mule, 67 hogs, 
20 chickens, and 2 dogs. Pots-mortem examinations showed no mosquitoes 
in the respiratory apparatus, indicating that the animals died cither from 
loss of blood, nervous exhaustion, or the effects of some toxin. It was 
officially reported that the milk supply from this district (Hialeah) was 
reduced to 1,000 gallons a day during the four days of the mosquito in- 
festation. 
ROCKY MOUNTAIN SPOTTED FEVER TICK AND 3LACK WIDOW 
The very serious tick-borne disease, Rocky Mountain spotted fever, 
heretofore confined to certain Rocky Mountain valleys in the Northwest, 
was found to be very prevalent in parts of Maryland and Virginia. By the 
middle of August 41 cases had been reported from this region. In this 
same region the black widow spider,- (Lathrodectes mac tans Fob. \ one of 
the more poisonous forms, the bite of which is often associated with 
serious results, was extremely numerous during the past summer.
