AN UNDESCRIBED SPECIES OF DRYOPEA INJURIOUS TO 

 PHYLLOSTACHYS. (APHIDIDAE-HOM.). 



BY A. C. BAKER, U. S. Bureau of Entomology. 



On March 21, 1916 Mr. Harold Morrison of the Federal 

 Horticultural Board collected at Yarrow, Md., a species of aphid 

 attacking the roots of potted Phyllostachys. The presence of the 

 insects was easily detected by means of the white wax secreted.
