Vasiform orifice subovatc or subtriangular in form. Caudal end pointed. 

 Operculum not one-half the length of orifice, and in width not quite filling the 

 open space, distal, free end truncate. Lingula well developed, nearly as long as 

 the orifice, spatulated distal portion convex, enlarged, rather bulbous, the bulbous 

 portion of which projects beyond the operculum setose. 



Adult male — Length, 0.93 nun.; forewing, 1.28 by 0.57 mm.; hind femur, 

 0.27 mm. ; hind tibia, 0.40 mm. ; hind tarsus, 0.25 mm. Eye less constricted than 

 in female, red in color. Body yellow, sutures of thoracic region dark, antennae 

 and legs pale ; forewing with one rather indistinct dusky spot, near the apex. 

 The third joint of antenna very long, longer than the rest of the joints together; 

 the seventh joint is shorter than sixth. Tibia of second pair of legs less than two- 

 third is also covered with minute markings as showing in the figure. Marginal rim 

 penis tapering, much shorter than valves. 



Adult female — Length, 1.26 mm.; forewing, 0.(j8 mm. Larger than male. 

 Eyes undivided, but deeply constricted about the middle. 



Hahitnt — On Oxalis corniculata L. in Shizuoka, collected by Mr. Masuda in 

 1908. Prof. Sasaki saj's that he has found a. species of Aleyrodes on the same 

 plant at Komaba, Tokyo, which may be the same as this new species. 



Type in the entomological collection of the Imperial Agricultural Experiment 

 Station, Japan, and cotype in U. S. N. M. 



Aleyrodes tokyonis n. sp. 

 (Figure 207, F-H) 



Pupa case — Size about 0.70 by 0.46 mm. Elliptical in form. With hand lens 

 ish in color, with margin pale. There is neither lateral nor dorsal secretion. 

 Dorsum convex but slightly, with many faint polygonal markings ; the outer 

 third is also covered with minute markings as showing in the figure. Marginal rim 

 rather wide, crenulation shallow. Abdominal segments well defined along the 

 dorsimeson. 



Vasiform orifice small, tubercled, subcircular; operculum relatively the same 

 shape, filling the orifice ; lingula slender, distal end enlarged and densely setose. 



Habitat — On Ilex Integra Tlmnb., Shibuya, Tokyo, collected by Baron N. 

 Takachiho, Sept., 1909-

Aleyrodes akebiae n. sp. 



(Figure 207, I-L) 



Pwpa case — Size about 0.70 by 0.46 mm. Elliptical in form. With hand lens 



pale yellow, while head and abdominal region are brown. Lateral fringe much 



longer than the body. This fringe is made up of slender, crystalline rods. The 



marginal rim is narrow and minutely crenulated. Margin with many spiny setae. 



Vasiform orifice subcordate, anterior margin straight; operculum not as 



broad as the orifice, about half its length, somewhat rectangular in form ; lingula
