The description of the species originally published in 1909 follows : 
Egg. — Elliptical, size about 0.24 mm. by 0.12 mm., with stalk unusually long; 
smoky in color, the shell smooth; eggs deposited promiscuously in the white, 
flocculent secretion of the adults. 
La rim, first stage. — Size about 0.338 mm. by 0.18 mm., subelliptical, very 
slightly narrowed caudad; yellowish white, with more or less rectangular spots 
of orange in the abdominal regions, eye-spots reddish. There is a fringe all 
around of white wax ; on the margin, cephalad of eyes, are six seta?, and on 
lateral margins of thoracic region are three on each side. On caudal margin 
are six seta?, the middle pair of which is considerably longer than others. 
On ventral surface, just within margin, all around, is a series of sparsely Bet, 
small, tubercled seta?. Legs and antenna? well developed. Vasiform orifice 
practically as in pupa-case. 
Pupa-ease. 1 — Size about 0.86 mm. by 0.53 mm. Subelliptical in shape, with 
slightly undulate outline. Color, under hand lens, yellowish brown ; empty 
pupa-case colorless, very fragile, soon falling from the leaf. On the margin, 
all around, is a fringe of more or less curled, short, white wax ribbons, and 
over the case and adjacent leaf area are many fragments of white wax rods, 
of variable length, profusely produced from the seven pairs of dorsal compound 
pores, which are situated, a pair on cephalic end and six pairs on the abdominal 
segments, the cephalic two pairs of wbich are smaller and nearer the median 
line. The margin, or rim, of each compound pore is thickened, and from within 
the cup there arises a rather large, fluted, cylindrical tube, extending upward 
about one-half its- length beyond the rim of cup. Within tube, at base, is a 
short conical elevation. The entire structure is brownish in color. Dorsum 
void of well-developed seta?, save a pair just within caudal margin. A pair of 
minute seta? occurs on margin near caudal end of case. There is, however, 
just within margin on case, all around, a row of brownish-colored, tubercled 
seta?. Vasiform orifice subcordate (fig. 35, c), about as long as wide, Cephalic 
margin straight, coinciding with cephalic margin of operculum. Operculum 
subrectangular, the lateral margins somewhat rounded; considerably wider 
than long and with caudal margin almost straight. Lingula relatively large,

* In the description of the waxy secretion, as originally given (1. c), this was de- 
BCribed as follows : 
'•There is a profuse dorsal exudation : Vint, a rather short, downward-curving fringe 
of pearly white wax, ail around, arising from just within margin ami curling outward 
and downward over margin to near surface of leaf. This fringe is hardly continuous 
hut is more or less split apart into ribbOM or hands. Second, more dorsally curving 
columns. These occur in a triangle, one on each side and one at end. These columns of 
while wax are about as blgb as pupa-case is wide. The pupa-case is almost ohseured by 
this exudation! when slewed from above." 
irdlng bo Doctor Morrill's observations the lecretlon, as above described, is abnor- 
mal to this specie and Is due to the effect of parasitism. Of many specimens examined 
hy him. Showing the secretion of this character, all were found to he parasit i/.ed ; and, on 
the other hand, this type of secretion wai never found on pupa cases not attacked by 
parasites. The normal secretion therefore is as described in the text.
