the last available report. The scouting thus far indicated relatively- 
heavy infestations in Presidio County and the southeastern corner of 
Hudspeth County, Tex. ; light infestations in Brewster, El Faso, Reeves, 
and Ward Counties, and. a trace in Midland and Pecos Counties, Tex. On 
November 12, 13, and 14 a study of 14 f ifelds.in . the Big Bend area in 
Presidio County, the most heavily, infested section in the United States, 
indicated 21 per cent of unpickable bollslii New Mexico, slight infestations 
were -found in Chaves, Dona Ana, Eddy, ,,and Oter.o Counties, and in Arizona 
in Graham, Greenlee, and Maricopa Counties, Scouting and the examination 
of gin trash in the Salt River Valley .{Maricopa County) indicate progress 
in the direction of the elimination of inf estation. 
COTTON LEAP WORM 
■ The cotton leaf worm ( Alabama argillacea Hbn. ) was first reported this 
year from Nueces County, Tex. , on Ju£e_\ 27. This is somewhat later than the 
observations,, of 1930, as this insect was very prevalent in practically all 
•fields in the lower Rio Grande Valley in the last week in June of -that year. 
No reports. from, the lower Mississippi Valley region were received until late 
August this year, and the insect reached the cotton too late to do. any 
material damage, . Late in October a single specimen was. taken in Michigan, 
and large numbers were present in Brown County, Wis., on October 1. The 
moths did serious damage to peaches in Cass County, Neby,., during the firs't 
week in October. ' No large flights were observed in any of the Northern . 
States this year. It will be recalled that last year a very heavy flight 
■occurred into the Northern States, extending over the East Central, Middle 
Atlantic, and New England States, finally reaching Canada. 
PERIODICAL CICADA 
Brood V of the periodical cicada ( Tibicina sept end ecim L.), a very 
compact brood centering in West Virginia and eastern Ohio, appeared in large 
numbers over practically its Entire range. . A very well defined' colony on' 
the eastern end of Long Island, New- York, was definitely confirmed by this 
year's observations. Brood V appeared during 1931 in the following counties;
