Data obtained fron collections of light traps operated at various 
places in Florida indicate that generally the relative abundance of the 
nore important species in the State was considerably less in 193^ than 
in 1935. 
Alon ; :; the Gulf coast, there has been no indication that salt- 
narsh species of mosquitoes have been more abundant in 193& than usual. 
Certain cities and towns in Texas suffered considerable annoyance from 
A. ae r -ypti (L. ) and a few cases of dengue fever wore reported; however, 
no epidemic of the disease occurred. 
On the west coast in Orecon and Washington, after the flooding 
of the Columbia and Willamette Rivers, the primary brood of A. vexans 
and A. aldrichi Dyarand Kr.ab emerged soon after April 21. Two success- 
ive broods emerged on May 18 and June 11 and these species continued 
to be generally abundant and troublesome until July 17, when high 
temperatures and low humidity caused a rapid decrease in numbers. 
C. pipiens caused considerable annoyance in a few localities during 
the summer in Oregon. Sixty-six cases cf malaria were reported in 
Oregon in 193° » the largest number of cases occurring in the State 
in any year since 1918, when malaria was first required to be reported 
to the State Board of Health. Eighty-three percent of these cases 
occurred in August, .September, and October. A nophele s maculip en nis 
Meig. , the principal vector of malaria in the State, was found to be 
very abundant in the vicinity of Prineville, Oreg., although no cases 
of malaria were reported from that locality. In the Cascade mountains, 
the snow-water species were reported abundant about Hay 2. The num- 
bers of these species, however, did not appear to be above the average 
during 193&. (E. C. Bishopp, Bureau of Entomology and Plant Quarantine,

ROCKY MOUNTAIN SPOTTED E^VER TICKS 
Reports from the Rocky Mountain region indicate that the Rocky 
Mountain spotted fever tick ( permacentcr andersoni Stiles) was about 
normal in abundince in 193°« Aside from its importance as the vector 
of Rocky Mountain spotted fever of man, it plays a continuous role in 
the ..transmis sion of tu laremia and it is also of distinct importance 
as a parasite and aim oyer of man and animals. This tick has been de- 
termined for tho first time as recurri ng in Arizona . This record con- 
sists of a male specimen sort frc?Pthe Lukachukaillountains, Ariz., on 
Juno 23, 1936. The numb.-r of cases of Reclry Mountain spotted fever 
in tho West was about normal. Tho death rate, as usual, varied widely, 
in different sections, ran in ;; from about 5 to about 80. Tho total 
number of cases reported to the United States Public Health Service 
up to November 1 was 166, and wore distributed as follows: Montana 
56, Wyoming ^5, Ore-on 32, Idaho 23, Colorado 7, Utah 1, California 1, 
and Arizona 1.
