inates the caudal pencil of white wax previously mentioned. Vasi- 
fonri orifice can not be made out with certainty, hut it is relatively 
small, short, and about twice as wide as long, and is surrounded with 
an obscure fluted rim. 
Adult $ . — Length about 0.86 mm.; fore-wing 1 by 0.46 mm.; 
immaculate. Body yellow, eyes reddish and dumb-bell shape, not 
divided. Antenna', joint 1, short, cup-shaped; joint 2, subpyriform, 
about two-thirds as wide as long; joint 3. quite long and relatively 
large, cylindrical, except at base, where it is tapering, not quite as long 
as joints 5, 6, and 7 together; joint 4, short, about one-half length of 
fifth; joints 5 and 6, subequal in length; joint 7, slightly longer than 
joint 4. Mentum much reduced in size, plainly abnormally reduced. 
Genitalia usual; valves strong and clasping at tip; penis curved upwards, 
tapering, and enlarged at base. 
This specie- occurs more or less singly on leaves of Qua res aquatica, 
on the campus of the Florida Agricultural College, at Lake City.

Larva.- Size about 0.78 by 0.52 mm. ; subelliptical in shape, becom- 
ing aarrower caudad. Color, light yellow. In very young larvae 
there is a rather narrow cottony marginal fringe, but in older specimens 
this La in most cases wanting. The margin is Hat and closely applied 
to leaf. Abdominal segments moderately distinct; thoracic segments 
obscure. Margin of case delicately crenulated, the ends of the wax 
tubes rounded, and the shallow indentures acute. Dorsum void of 
pores, papillae, and seta'. There are. however, three pairs of setae on 
margin: A Bmall pair at cephalic end, a well-developed pair at caudal 
end, and a small pair at caudal end. a seta on each side of larger pair. 
There i- n<> marginal rim. Vasiform orifice essentially as in pupa- 
case. On ventral surface the legs are quite obscure. The small eye 
spots are reddish. 
Pupa-case. Size, about 1. L5 by 0.83 mm.; broadly elliptical in shape, 
and bright lemon-yellow in color. In the more mature specimens there 
i> more or less of reddish coloration, due to the developing pupa within, 
Pupa case rajher strongly convex, and but little flattened at the mar- 
gin. There is do lateral fringe, but a more or less slanting waxen rim 
is present in older specimens, raising the case a short distance from
