VAGABOND G- ALL-LOUSE ( Pemphigus vag abundus TTalsh) 
Nebraska M, H, Swenk (August l): Complaints of deformity by the vagabond 
gall-louse on the cottonwood continued to be received during early 
August. (August l) : In western Nebraska reports of injury to 
cottonwood trees by the vagabond gall-louse were received. 
OYSTER-SHELL SCALE ( Lepidosaphes u lmi L.) 
Indiana H. F. Dietz (July 18): The light-brown form of oyster-shell scale 
began laying eggs on July 6. "The second brood should appear within 
the next two weeks* The gray-brown form is in the early third 
instar at the present time. We have no data on the apple form, 
which is not serious in this State. In this connection it should 
be pointed out that the nomenclature for the three different forms 
of oyster-shell scale, published by Glenn in the Journal of Economic 
Entomology for April, 1921, should be followed, i. e., the JLi£ht- 
brown f orm ,v/hich is two-brooded and which lives on Carolina poplar 
birt cannot maintain itself on apple; the app le form , which is like- 
wise two-brooded and lives on apple but cannot live on Carolina 
poplar; and the jgrajr-brown form, which is single-brooded but cannot 
maintain itself on apple, at least in this State. 
PALE TUSSOCK MOTH ( Kalis idota tessellaris S . & A. ) 
New York R. E. Horsey (August): This insect has given us more trouble than 
any other pest this month. It is found in all parts of the city 
wherever the plane tree is planted, as well as in Highland Park. 
On several streets planted to plane trees the trees were sprayed 
and we are still at it. In fact, this insect has done fully as 
much damage to plane trees as the elm leaf-beetle did to elms. 
COTTONWOOD LEAF-BEETLE (Lin a script a Fab, ) 
New Jersey R. B. Lott (August 19): Near New Brunswick this insect is very 
plentiful on willow and poplar, especially the latter. 
Nebraska M. H. Swenk (August l) : In western Nebraska reports of injury to 
cottonwood trees by the cottonwood leaf-beetle were received. 
^August l) : Injury to the cottonwood trees in the City Park at 
Callaway, Custer County, by the cottonwood leaf-beetle was com- 
plained of during early August.
