gland openings on the sides. Pygidium cleft at intervals and having the 

 margin distinctly denticulate, more plainly so in some specimens than in 

 others. Median and second pairs of lobes well developed, often with 

 thickenings of the body wall extending anteriorly from them ; third pair 

 wholly wanting. Median pair separated by a distance about equal to tiie 

 width of one of the lobes. Each lobe of the second pair composed of 

 two distinct and separate lobules, the inner one being larger and often 

 approximating the median lobes in size. Interval between the median 

 lobe occupied by two more or less distinct teeth, anterior to which is a 

 transverse oval gland opening. Two spines anterior to each median 

 lobe, and immediately outside each median lobe, a large plate, anterior to 

 which is a spine. An oval gland opening between this plate and the 

 second lobe, and, outside this lobe, a second plate, a denticulate space 

 with two marginal gland openings and a spine, then one or two plates, 

 followed by another denticulate space with two marginal gland openings 

 and a spine, and, lastly, the terminal group of two plates. 



P^ive groups of circumgenital glands; median, 5 to 7; anterior 

 laterals, 9 to 14 ; posterior laterals, 7 to 14. 



Male. — Unknown. 



Habitat, — On East Indian bamboo from the Department of Agri- 

 culture, Washington, D. C. 



I take pleasure in naming this insect after Dr. L. ,0. Howard, 

 United States Entomologist, the extent and value of whose work is well 

 known by all workers in entomology. 



Chionapsis Lintneri, Comst. 

 Since this species was described in 1882, in Prof Comstock's second 

 Report of the Department of Entomolgy of the Cornell University Ex- 

 periment Station, no mention has been made of its having been dis- 

 covered in other localities, except in the instance mentioned in a previous 

 paragraph of this paper. On January 12, 1898, Mr. A. F. Burgess, an 

 assistant in the scientific department of the work of extermination of the 

 Gypsy moth, found a Chionaspis abundant on Almis in a swamp in Stone- 

 ham, Mass. I made an examination of these specimens and found them 

 to be C. Lintneri, Comst. The specimens occur only at the bases of 

 the young trees. 



Chionaspis -MINOR, Mask. 



In the fall of 1897, Prof A. L. Quaintance sent me a piece of a 

 branch of a " China-tree " (Melia azedarach) badly infested with a white
