GENERAL F3EDEES 
GRASSHOPPERS (Acrididae) 
Illinois. R. C. Hall (September): An unusual infestation of grasshoppers 
was observed on August 6 in a young planting of white and pitch pine 
at Bath. In one area where these two species had been planted about 
75 percent had been killed by these insects. The damage was caused by 
defoliation and by the pruning and girdling of small branches. Some 
trees were pruned down so that only a single naked leader remained. 
Four species were collected, Melanoplus august ipennis Dodge, Schisto - 
cerca alutacea Harr. , Spharagemo r. collare Scudd. , and Fsinidia fenes- 
tralis Serv. 
ITorth Dakota. F. D. Butcher (September 21): Bright, warm days during late 
August an:'. September were favorable for continued egQ laying. Adults 
of Gamnula t>e Hue Ida Scudd. have practically disappeared, but their 
eggs are in the ground. Adults of other species on pastures a.nd range 
in western ITorth Dakota are numerous in' some places. M. differentialis 
Thos. is Pairing a successful comeback in the- southwestern part of the 
State. 
South Dakota. H. C. Severin (September 20): Range species of grasshoppers 
have increased enormously in numbers over much of the western two-thirds 
of South Dakota. Grasshoppers attacking cultivated crops were chiefly 
M. "blvittatus Say, 1!. me xicanus Sauss., and Dissosteira Carolina L. 
Damage was spotted in gardens, small grains, alfalfa, sweetclover, flax, 
and corn. 
Iowa. H, E. Jaques (September 2h): Grasshoppers are unus'qally abundant 
throughout much of the State. M. differentialis and M« f emur-ru.brum 
DeC-. predominate. Some of the rarer species are rather easily found. 
Kansas. H, R. Bryson (September 25): Grasshoppers occur in considerable 
abundance in some localities. The species most common^ encountered are 
M. dif f erentialis , M. bivit t atus , M. mexicanus , and M. femur - rub rum . 
FALL ARMYWORM (Lajohygma fruginerda S. & A.) 
Texas. F. L, Thomas (September lo): Fa.ll armyworms, two- thirds grown, were 
assuming the army habit on Bermuda lawns at College Station, Bryan, and 
Uavasota on September 11. Eggs were laid about the first of September 
and pupation is taking place at the present date. Parasites are present 
but not sufficiently abundant to prevent the appearance of another gen- 
eration. 
CLOUDLESS SULPHUR ( Catopsilia eubule L. ) 
South Carolina. C. C, Ba,re (September 1J,): A ilistinct migration of this 
butterfly was observed at the Truck Experiment Station at Charleston 
fro - :" 2 to 3 P* 1 '-"'-* on September 13. The afternoon was cloudy, the temper- 
ature during the flight was 1V° F. , and the relative humidity was 67
