Pseudococcus aceris Geoff. This comparatively 
rare species was observed in immense numbers on the bark of a 
hard maple at Albany N. Y., August 6. It was also observed in 
considerable numbers on hard maples at Worcester Mass. The 
male cocoons were present in thousands and in places formed 
large white masses on the trunk, giving a tree the appearance 
of being affected by a fungus. Some immature individuals were 
wandering over the masses of the male cocoons. The leaves 
were also badly affected. The cottony remains of adults were 
abundant, and here and there old females were still producing 
young, as a number of very small individuals were observed, and 
partly grown ones were assembled on the under surface of the 
leaf in long rows on both sides of the principal veins. There is 
‘a marked, subacid, not unpleasant odor about this species when 
present in large numbers. It is not nearly so offensive as 
bhecaninumiinigrofasciatum Perg. 
Chermes pinicorticis Fitch is always more or less 
injurious to white pines in Washington park, Albany, but this 
year it has been exceptionally abundant, not only giving con- 
‘siderable portions of the trunk a whitewashed appearance but 
literally plastering the under surface of many limbs. A number 
of these pines, as a consequence, have a thin foliage and are 
sickly. It was also observed in numbers on white pines at 
Round Lake N. Y. 
Garden and other insects 
Blister beetles. Several species were brought to notice 
through the depredations of the adults on various plants. The 
‘striped blister beetle, Epicauta vittata Fabr., attacked 
beets, potatoes, beans and tomatoes about the middle of August, 
at Valatie, Columbia co. It was reported as very numerous and 
to have devoured all the beets and tomatoes and then to have 
attacked potatoes. The exceedingly common black blister 
beetle, Epicauta pennsylvanica DeG., suddenly 
attacked sugar beets about the same time at Cobleskill, Scho- 
harie co., and some patches were destroyed. The latter part of 
August, this species was reported as injurious to potato vines
