 p. 36. (The Coccidse, Genera Chio. and Hemichio.) 



This species was found by the author on Rhus sp. in 

 Aomori City. This is the first time it has been recorded 

 from Japan.

 lie. 



This species was found by the author on Ahius ja-ponica 

 (Hanno-ki) Salix bahylonica (Shidare-yanagi), and Salix 

 sp. in Gifu-ken. A. Craw has also recorded it on wistaria 

 from Japan.

Plate XHI, Fig. 84. 



Scale of Female. — Length about 2 to 2.5 mm., width about 1.5 mm. 

 Decidedly broadened posteriorly; moderately strong in texture; color, pale 

 straw-white. Exuviae, i mm. long, first skin about .3 mm. long, elliptical, 

 slightly broadened posteriorly; a median longitudinal ridge; antennae promi- 

 nent; color transparent. Second skin, large; slightly convex; posterior end 

 orange-yellow. 



Fetnale. — Body of the female rather long and slender; length 1.2 to 2 mm.; 

 width .5 to I mm.; elliptical in outline. The last abdominal segment pre- 

 sents the following characters: the lobes are very inconspicuous; the median 

 lobes almost invisible, pointed; the second lobes are very small, being simply 

 an angular projection of the body-wall; the third lobes are about twice as 

 large as the second and project a little beyond the margin of the segment. 

 The second and third lobes are more or less ciliated. Many suboval, thick- 

 ened bodies in near the margin are very conspicuous as shown in the figure. 

 The gland-spines are arranged as follows: i, i, 2, i, i, i; they are similar 

 except that the last one is forked; one between first and second lobes, one 

 between second and third lobes, two laterad of third lobes and three more 

 beyond that. Spines are prominent, extending beyond plates. The first 

 pair are situated near the lateral margin of the first lobes; the second about 

 the lateral margin of the base of the outer lobules of the second lobes; the 

 third pair on the lateral margin of the third lobes; another pair of spines 

 outside of the third lobes. There are five groups of spinnerets; the anterior 

 group contains seven to ten; the anterior laterals, twelve to sixteen; the pos- 

 terior laterals, nine to fifteen.
