entomologist. The whole volume shows the same careful preparation 
as its predecessors, and is well illustrated, a number of the figures 
being new. 
Notes on the Clover Mite.—This little creature (Bryobia pra- 
tensis) has been extremely abundant during the past spring at Han- 
over, N. H. It appeared in swarms early in April, congregating on 
window-sills of houses and other buildings, and continued abundant 
until early in June. In Dr. Riley’s recent Insect Life article upon the 
species it is surmised that at the north the mite passes the winter in 
the egg state, but this evidently is not the case in the latitude of Han- 
over.—C. M. W. 
Entomological Notes.—A bulletin (No. 19) of unusual interest 
comes from the Colorado Experiment Station. It contains Prof. Gil- 
lette’s “Observations Upon Injurious Insects, season of 1891.” It 
includes discussions of the fruit-tree leaf-roller (Cacoecea argyrospila), 
box-elder leaf-roller ( C. semiferana), grape-vine leaf-hopper ( Typhlocy- 
ba vitifex), gooseberry fruit-fly (Trypeta canadensis), imported cur- 
rant borer (Sesia tipuliformis), and several others. There are twelve 
good illustrations, all but one being original. 
Number 4 of the current volume of the Ohio Station Bulletin con- 
tains an extended discussion of the “ insects which burrow in the stem 
of wheat.” by Mr. F. M. Webster. Eight species are enumerated. 
At the next meeting of the Association of Agricultural Colleges and 
Experiment Stations, Chairman Lawrence Bruner, of the Committee 
on Entomology, proposes to describe the working facilities, library, col- 
lections, equipment, etc., of the various entomologists represented in 
the Association. 
Prof. S. A. Forbes, in charge of the entomological exhibit at the 
World’s Fair, is endeavoring to get together a biological collection of 
all the insects whose life histories have been worked out in whole or in 
part by the experiment stations. 
In Bulletin No. 19 of Hatch Experiment Station of Massachusetts 
Prof. C. H. Fernald has published an excellent account of the present 
status of the gypsy moth ( Oenerea dispar), illustrated by.an admira-
