Eggs of the green apple aphid are at present abundant on the twigs of 
young trees ia many apple orchards of southwestern Ontario. 
The tussock caterpillar Halisidota tesselaris S. & A. appeared in immense 
nunbers in southwestern Ontario during the late summer and fall of 1923, attacking 
various trees and shrubs , and doing considerable injury to apple orchards. This 
insect was abundant throughout eastern Canada, but it is not yet possible to fore- 
cast accurately the probable extent of its occurrence during; the caning season.

GRASSHOPPERS ( Acrid iidae) 
Texas C. H. Gable (January 21): The grasshopper situation appears quite 
alarming to me. Mr. Russell, at my suggestion, has made rather an 
extensive examination of grasshopper eggs in northern Texas and 
finds that from 85 to 95 per cent are no' 7 ? in good hatch able condi- 
tion. He gathered practically two 5-pound candy boxes full of egg 
masses in a very short time. He states that "in some places as 
many as a dozer masses were found within 5 or 6 inches."

HIS SI AN FLY (P hytonhaga destructo r Say) 
Michigan R. H. Pet tit (March 10): We have quite a bit of Hessian fly in- 
festation scattered in places whore sowings were* trade before the 
fly-free date. 
Illinois 17. P. Flint: Abundant rains throughout the late summer and early 
fall of IS 23 caused a heavy growth of the volunteer wheat in stubble 
fields throughout the State • This wheat is moderately to heavily 
infested with the Hessian fly and will provide sufficient spring 
adults for a moderately heavy infestation in the spring of .1924. 
In thb sown fields there is very little infestation present except 
in the southwestern part of the State, where a number of fields 
were seeded early. The infestations in these fields will run from 
60 to SO per cent. 
Nebraska M. H. Swenk (March 12): Organized campaigns to await the date cf 
safe seeding of winter wheat, as announced by the Department cf 
Entomology of the Nebraska Experiment Station, were conducted in 
11 counties that showed a heavy infestation and experienced con- 
siderable losses during the spring of 1923. These organized coun- 
ties were Cass, Otoe, Johnson, Richardson, Douglas, Saunders, Colfax, 
Seward, Fillmore, Buffalo, and Furnas. On the oasis of the field 
observation station conducted at Plattsmouth, Cass County, in the 
fall of 1923, dates of safe seeding were announced for these coun- 
ties, according to location, from September 29 to 0ctooer4. Sub- 
sequent checks in several of these counties showed that the 'wheat 
seeded on or after the announced date of safe seeding was free from 
infestation. In most cf these counties a high percentage of the
