Chionaspis bambuscs Cockerell, Psyche, Supp., 1896, p. 21; Bull. No. 4, 

 T. S., Div. Ent., U. S. Dept. Agric, 1896, p. 54. 



This species was found by the author on the leaves of 

 bamboo, in Akabane. Previous to this O. Takahashi, 

 Tokyo, sent specimens of the same to the Division of 

 Entomology, U. S. Department of Agriculture, from which 

 Professor Cockerell described the species.

Plate XIII, Figs. 82 and 83. 



Scale of Female. — Very long and slender; length about 2.5 mm., width .4 

 mm.; sides straight, parallel, sometimes curved; color snow-white. First 

 skin elliptical, almost transparent; median longitudinal ridge distinct; antennae 

 prominent; second skin very much longer, slightly convex, posterior end 

 yellowish; exuviae .75 mm. long. 



Female. — Adult female very small; length less than i mm., width about 

 .3 mm. Last abdominal segment presents the following characters: — 



One pair of median lobes, short, diverging, and slightly notched on inner 

 margin. One large gland-spine laterad of each median lobe. The plate-like 

 margins are broad, rounded, and serrulate. Second pair of gland-spines 

 rising from lateral side of the plate-like margin; the third pair of gland-spines 

 is very conspicuous, being separated by a plate-like margin; first pair of 

 spines on each side of median lobe near base; second pair of spines on plate- 

 like margin near the lateral margin; third pair near the base of third pair of 

 gland-spines. Spinnerets wanting. 



This species was found by the author on Phyllostachys 

 bambusoides (Ya-dake) at Hikosan, Kiushiu. 



C. L. Marlatt, who has examined the specimens, says: 

 "The structure of the female somewhat approaches genus 

 Leucasfis^ but the scale is entirely different from the Leu- 

 casfis type. To properly place it, one should have the 

 male, which is wanting."

 Jr. University, and co-types in the author's collection.
