Tam unable to agree with Mr. Ashmead, in referring this species to 
Fitch’s Aleurodes (Aspidiotus) gossypv. From a study of the single 
type specimen of Alewrodes gossypii, which was received by Dr. Fitch 
from Nigapo, China, certain important differences have appeared. 
There is no dark medio-dorsal stripe in gossyp77,and the series all 
around of submarginal pores and waxen rods is also wanting. In 
gossypii. the pupa-case is quite convex and the marginal area is 
strongly reflexed down to the margin of the leaf, much after the man- 
ner of a Lecanium. In jitchi, however, the case is scarcely at all con- 
vex, regularly elliptical in shape, and is raised on a vertical fringe all 
around of white wax. The two species are scarcely of the same type. 
From the convexity of the single specimen of Aleurodes gossypii, I 
am inclined to regard it as representing the pupal stage, and not the 
larval, as regarded by Mr. C. L. Marlatt. (Ento. News, Vol. X, p. 146.)

Pupa-case.—Length about 0.83 mm.; width about 0.57 mm.; vary- 
ing somewhat in size and the subelliptical shape. Color of fresh pupa- 
case, according to Mr. Pergande’s note (Division of Entomology, No. 
6962), ** pale, semitransparent, greenish, marked on thorax and abdo- 
men with subdorsal rows of blackish spots. Margin of body and anal 
plates yellowish.” Dried specimens on leaf are pale lemon yellow, 
and the spots are deep red. In balsam the color of case is pale lemon 
yellow, and in more mature specimens there is more or less of orange, 
due, without doubt, to.the developing imago. 
There is no marginal or lateral fringe, in the strict sense of the 
word—that is, coming from the lateral pores—but on the extreme 
outer margin of dorsum all around there is a very closely set row of 
conical papille, from which originates a beautiful fringe composed of 
long, slightly curved, glassy, waxen rods—a rod from each papilla. 
These papille are very closely set, touching each other at their bases, 
and the rods are frequently nearly as long as the pupa-case is wide, and 
show basally, minute file-like serrations. The fringe is more or less 
separated into rays of rods extending mesad quite to case. There are 
usually from 3 to 8 rods in each ray, and these individual rays become 
somewhat curved, independent of the others. 
Margin of case crenulated, the incisions between wax tubes usually 
quite shallow and acute. Pupa-case applied closely to leaf, and quite
