Adult female (dried specimens): Dark purple, vritli the eggs or 

 young also dark purple; length 0.9 to 1 mm.; breadth at widest 

 part 0.4 to 0.5 mm., of normal CMonaspis type, tapering anteriorly; 

 body nearly hyaline; parastigmal glands variable, sometimes as 

 man}' as 9. Anal plate broader than long, 0.26 b}' 0.38 mm.; in 

 older specimens distinctly and generally chitinized and broMTi, nearly 

 li3^aline in recentl}^ matured females; median lobes touching at base 

 and wideh' divaricating toward tips; latter rounded. Inner lobe of 

 iirst lateral pair one-half width of median; outer lobes, same pair, 

 "v^er}^ short and much smaller; second lateral pair represented by the 

 inner lobe onl}', which is similar to the same lobe of the first lateral 

 pair; outer lobe apparently practically wanting; lateral lobes directed 

 distinctly toward apex of segment; lateral teeth represented only 

 by the projections laterad of the large oblique marginal glands; 

 incisions inconspicuous; paraphyses wanting; plate j, including the 

 median, 2, 2, 2, 2, 4-5; spines normal; anal opening one-third or less 

 from base, circular, about the diameter of the first lateral lobe; para- 

 genitals 12-13, 20-29, 18-22; obliciue marginal pores 1, 2, 2, 2; dorsal 

 pores small, nearly circular; inner row or group next to paragenitals 

 7-9; irregular row extending from third incision, more or less in two 

 groups, of some 15 pores altogether; followed by an exterior row of 

 some 12 pores, number of pores, however, variable; basal tliicken- 

 ings inconspicuous or wanting; ventral thickenings the suffused 

 chitinization of the anal plate already noted, slightly heavier below 

 median lobes. 



Type. — Bureau of Entomology No. 14144. Collected on poplar, 

 probabl}^ Populus tremula, at Wu Tai Shan, Shansi, China, by F. N. 

 lleyer. Received February 26, 1908. 



LEUCASPIS INDICA n. sp. 

 (Plate VII, fig. 2. ) 



Scale of female: White, elongate, narrow, convex, flattened at tip, 

 'easil}?' falling from the insect beneath. 



Scale of male: Not noted. 



Adult female: Entirely inclosed within the swollen, strongly chiti- 

 nized second stage, latter 0.5 to 0.6 mm. long, elongate oval, dark 

 reddish brown. Adult female hyaline, elongate, sides subparallel. 

 A.nal plate very minute, about 0.1 mm. in diameter, rounded, longi- 

 tudinally striate. Margin with a series of elongate plate-Kke proc- 

 esses; lobes, incisions, and paraphyses wanting. The processes 

 referred to are truncate or slightly spatulate at tip, and are of two 

 lengths; the long ones are the second, fifth, and ninth from the cen- 

 ter and are homologous to the lobes of other species; between the 

 median long pair is a central short pair, then be^^'ond the first long 

 plate two other short ones, and beyond the second long plate three
