Populations in all areas were greatly reduced from those of the 193^ survey, 
except in western Iowa , eastern Nebraska* eastern Kansas, southern Wisconsin, 
and the northern half of the Lower Peninsula of Michigan. In these areas 
light or local infestations have developed into severe or very severe ones. 
Heavy rains and cloudy weather during the hatching period greatly reduced 
the infestations of Cannula pellucida Scudd. and other species in northern 
Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan. Melan- 
oplus mexicanus Sauss, was the dominant species over most of the area. C. 
pellucida was greatly reduced in numbers by unfavorable weather. M. differ - 
ent ia'lis Thos. is building up again along the river courses of South Dakota, 
western Iowa, Nebraska, and Kansas. M. bivittatus Say is also increasing in 
these places, where succulent food was plentiful last summer, and is again 
becoming abundant in counties fringing the mountains in Colorado, Wyoming, 
and Montana. M. differentialis and M. bivittatus Say had become scarce under 
the severe, drought of the past several years. M. femur - rubrum DeG. was 
numerous in alfalfa fields and grasslands in the more humid regions, M. 
packardii Scudd, was an important species in the Dakotas and Mountain States. 
Certain so-called prairie forms, as Aulocara elliotti Thomas, Ageneotettix 
deorum Scudd., and Drepa n opterna femoratum Scudd., were also abundant, 
causing much damage to grazing lands and cultivated crops adjoining in the 
stock-raising areas. (R. L. Shotwell, Bureau of Entomology and Plant 
Quarantine, U. S. D. A.) 
■MORMON CRICKET AND COULEE CRICKET 
An unprecedented outbreak of the mormon cricket is in progress in 
some of the Western States. During the year eight States — Montana, Idaho, 
Wyoming, Nevada, Utah, Colorado, Washington, and Oregon — reported outbreaks 
of varying intensity and extent, and all of these States except Utah and 
Oregon carried on control campaigns. Prom extensive egg surveys made this 
fall, severe infestation may be anticipated next year. The accompanying map 
showing the general location of infestations was prepared from the egg-survey 
data. The following acreage was found to be infested: Colorado, 308,300; 
Idaho, l,gl5,10U; Montana, 1,2^9,570; Nevada, 9^,999; Oregon, 23,000; 
Utah, 109, SUO; Washington, 199>780; Wyoming, 1,1^1,159; total, 5i831>75 2 . 
The most threatening infestations are in Montana, Idaho, Nevada, and Wyoming, 
situated in or near the agricultural sections. The area of infestation in 
Washington is relatively small but is located in valuable agricultural land. 
The coulee cricket developed into outbreak numbers in an area of 
U,100 acres lying east of Cashmere and bordering the Wena.tch.ee Valley in 
Chelan County, Wash. Considerable agricultural land is threatened. (P. T. 
Cowan, Bureau of Entomology and Plant Quarantine, U. S. D, A.) 
CHINCH BUG 
The great numbers of chinch bugs in hibernation at the beginning of 
the jrear presaged the most severe and widespread outbreak in 50 years. They 
were known to be abundant from central Oklahoma to eastern Ohio, with the 
greatest density of population in Missouri, southern Iowa, and central and 
northern Illinois. In the most heavily infested region thousands of bugs 
were often present in a single clump of bunch grass, the maximum reported 
being about 60,000. The only area where winter mortality of
