hand lens, is much hidden by the dorsal exudation of whitish waxen 
ribbons or plumes. Under microscope the case is very dark brown. 
These waxy ribbons, in perfect specimens, are quite twice as long as 
the case is wide: these occur usually from 3 to 4 on each side of dor- 
sum and more or less continuous at base, extending upward and out- 
ward. There is also a central, upright, thick column, composed of 
the united exudations from the more cephalic of the abdominal seg- 
ments. In the caudal pair the plumes are semi-tubular. From the 
suture extending cephalad to margin of case from the third thoracic 
segment, there arises on each side a thin ribbon of wax, the two 
united cephalad, and spreading distally into a broad wavy plume, and 
from between which arises a thin but broad plume. There is a lateral 
fringe of amorphous wax extending out in considerable quantity on 
the leaf, all around margin of case. Margin of case crenulated with 
a double row of wax tubes, the dorsal series somewhat within the 
lower. Just within the rim all around is a series of small dark-colored 
disc-like tubercles or dots, and small dots of this character may occur 
in transverse rows across the dorsum at about the middle of the seg- 
ment-. There are two pairs of well-developed, brownish-colored seta? 
at caudal end. a pair just within caudal margin, and a pair at vasit'orm 
orifice; on the margin of case there is a small pair in the usual caudo- 
lateral region, and a pair at cephalic end. Under high power of 
microscope the subdorsal area is seen to be covered with minute pores, 
from which is exuded the ribbons of wax. These pores also occur 
along the central abdominal line. Vasiform orifice subcordate, almost 
as I » road as long; cephalic margin nearly straight, caudal end bluntly 
rounded. Operculum about one-third the length of orifice; lingula 
quite rudimentary, short, not more than half the length of operculum. 
Pupa-case but little convex, even at maturity. Body segments moder- 
ately distinct. On ventral surface, feet quite distinct. 
Adult? — Length about 0.80 mm.; fore-wing 0.95 by 0.33 mm.; 
length of hind tibia 0.24 mm.; length of hind tarsus 0.17 mm.; color, 
Lemon yellow, legs and antenme paler. Byes but little divided, dorsal 
portion reddish; central, deep brownish red; wings immaculate. Joint 
1 of antenna 1 short, not quite one-half length of second; joint 2, pear- 
shaped, about one-half as wide as long; joint 3, about as long as the four 
remaining joints together; joint 4, about two-thirds length of fifth; 
joint - 5, ♦'». and 7. subequal in length; joint 5, somewhat swollen dis- 
tally; joint 7. with a BtrictureOD one side about the middle of its length, 
tapering to an acute point. Omentum of three joints, usual. Operca 
Lum seen in lateral aspect and w hen elevated, subcorneal; Lingula con- 
siderably protruded subcylindrical, with an upward bend near middle, 
and aearer end there is another bend, but down to the horizontal. 
A rather common species in Florida hammocks and higher wood- 
lands; on leav es of various plants, as Pci'xcd curoluwiixiis, Miujnoli (
