REPORT OF THE STATE EXTOMOLOGIST 1901 749 



Psendococcus ace r is Geoff. This comparatively 

 rare species was observed in immense numbers on the bark of a 

 Jiard 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 

 tibundant, and here and there old females were still producing 

 joung, 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 

 n marked, subacid, not unpleasant odor about this species when 

 present in large numbers. It is not nearly so offensive as 

 Lecanium nigrofasciatum 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 



Uound 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 Yalatie, Columbia co. It was reported as very numerous and 

 to have devoured all tlie 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
