88 THE CANADIAN ENTOMOLOGIST. 



when well developed rounded on the posterior extremities, sometimes 

 faintly serrate, with a pair of spines in the notch ; when rudimentary, only 

 slightly produced, with the pair of spines in the notch often inconspicuous 

 or absent. Second lobe composed of two lobules, inner large and 

 rounded, outer smaller and bluntly pointed. Two spines anterior to the 

 outer edge of each median lobe. A well-developed plate and a marginal 

 gland opening between the median and second lobes. Two spines at the 

 base of the second lobe, and outside this lobe, a second plate, followed 

 by a deep notch in which is a marginal gland opening. Then two spines 

 and a third plate followed by a second notch in which is a marginal 

 gland opening, and, after a short space, the fourth and last plate. 

 Dorsal rows of oval gland openings present. 



Five groups of circumgenital glands : median, 5 or 6 ; anterior 

 laterals, 10 to 13 ; posterior laterals, 13 to 27. 



Male. — Unknown. 



This species may be distinguished from other known members of the 

 genus by the characteristic appearance of the scales, particularly those of 

 the female. It belongs to the group o{ euge?ii(V (Green), chmensis (Ckll.), 

 etc., or those having a terminal median notch in the pygidium. 



Habitat. — On an unidentified plant from Ceres, Cape Colony, South 

 Africa, sent by the Government entomologist, Mr. Charles P. Lounsbury, 

 to Dr. L. O. Howard, at Washington, and also to the writer. The female 

 scales are indiscriminately distributed over both surfaces of the leaves, 

 while the male scales occur in groups chiefly on the under surface. 



I take pleasure in naming this insect after its discoverer, Mr. Louns- 

 bury, who is doing very valuable and praiseworthy work in economic 



entomology. 



Chionaspis Howardi, n. sp. 



Scale of Female. — Elongated, narrow, sides nearly parallel. White, 

 with the exuvise variable in colour, being yellow, brown or green ; two 

 parts of the same exuvia often of different colours. Second exuvia 

 obscured by the waxy secretion that covers it. Length of exuviae about 

 .7 mm.; total length of the scale, 1.5 to 1.7 mm. 



Scale of Male. — Elongated, sides parallel, with a distinct median 

 keel ; creamy white with the exuvia of about the same colour. Length 

 about 1.2 mm. 



Female. — Elongated, very slightly broadeiied posteriorly, with the 

 segmentation not pronounced, the posterior segments having numerous
