deeply notched, thus becoming conspicuously crenate. Each lobe is 
deeply incised at its base, but except for this it would form a nearly 
right-angled triangle, the right angle being the inner basal one. The 
length of each lobe in the median line is about as great as its breadth 
at the base, or somewhat greater. Immediately outside each lobe is a 
spine, then comes a large plate, conical in outline; then a pair of lobes 
resembling in shape human incisor teeth, but more narrowed basally; 
then a long spine; then a pair of oblong plates, followed by what may 
be a very rudimentary lobe, marked at the base like the previous pair 
of lobes by a round, low prominence bearing a short hair; then after a 
short interval comes a low, broad serration on the margin, followed by 
a number of minute serrations, toward the end of which is another 
short hair springing from a round spot; after this comes a short interval 
and then a very long spine-like plate; then a prominence bearing a 
gland; then after an interval two very long, spine-like plates. The 
saccular glands along the margin, as in other species, are about twice 
as long as broad. Close to and parallel with the margin are seven 
transversely elongate pores, rod-like in form. 
Habitat.—Tokio, Japan, on orange. (Takahaski; Div. Ent. Dept. 
Agr. No. 6490.) 
Allied to C. braziliensis Sign., C. thee Mask., and C. minor Mask., but 
seale much broader. C. minor, which it much resembles structurally, 
has a white seale. (. latus is quite distinct, structurally, from C. citri. 
Chionaspis bambusz n. sp.

bles C. vaceinii a good 
deal, but the four (two 
pairs) lobes are smaller, and the median ones narrower and not touching 
at their bases as in vaccinii. The ventral grouped glands are in five 
groups, as usual, but the orifices are much less numerous than in vae- 
cinit. The oval (dorsal) pores are very large and distinct; udjacent to 
the lobes they form “incisions with thickened edges,” as in some spe- 
cies of Aspidiotus. The spine like plates are large; the margin ceph- 
alad of the fourth of these plates is serrate. 
Fic. 5.—Chionaspis bambuse (from drawing by Ceckerell).
