REPORT OF THE STATE ENTOMOLOGIST 1901 T6L 
Montreal in Canada. The first record of its appearance in the 
state of New York was in 1864. Within late years, from being 
an occasional visitor, it seems to have established itself in West- 
chester county, and at Poughkeepsie. In other localities in the 
state it is occasionally abundant, as in Rochester, where, accord- 
ing to Mr Bunker, it ‘‘ swarmed ” one season, several years ago. 
Prof. L. M. Underwood has written me that on Sep. 12, 1882, 
he saw several examples flying over the low swales near the 
Rhinebeck and Connecticut railroad in Columbia county. It 
has not been observed in the neighborhood of Albany. A single 
example was taken at New Baltimore, 17 miles south of Albany, 
in the month of September. 
' Rose scale insect (Aulacaspis rosae Sandb.) This de- 
structive southern species was found June 3 in abundance on 
blackberry bushes at Hudson N. Y. The young were appearing 
in considerable numbers at this time. It was breeding in large 
numbers on cuttings from a crimson rambler rose brought from 
Cobleskill N. Y. Oct. 18. Adult female scales were abundant 
and several parasites, Arrhenophagus chionaspidis 
Aur. were observed crawling on the twigs. This scale insect 
was also sent in on raspberry plants from Cornwall N. Y. This 
is a Species which is brought to attention at infrequent inter- 
vals in this state. One reason for this may be found in its 
general resemblance to the exceedingly common Chionaspis 
furfura Fitch, and it is not at all unlikely that many after 
a glance have concluded that the scale on the raspberry or 
blackberry was the scurfy bark louse and therefore not pushed 
the inquiry further. The species is represented on pl. 4, fig. 3, 4. 
EXPERIMENTAL WORK AGAINST THE SAN JOSE SCALE 
INSECT 
The tests of various insecticides begun last year were con- 
tinued in the same orchard during the present season, and in the 
main the results in 1900 were confirmed, and our confidence in 
a mechanical crude petroleum emulsion much increased. The 
chief aim of experimental work along this line is to make com- 
parative tests of various insecticides, and naturally some of the 
Substances used are not so effective as one might desire; yet, 
in spite of that drawback, the experimental orchard is in much
