jecting caudad to margin of orifice. Just cephalad of orifice are two 
sets of crescent-shaped thickenings. A shallow furrow extends caudad 
from orifice to margin of pupa-case. On ventral surface, the reduced 
legs may be made out with difficulty. 
Adult 9 . — Length about 0.833 nun. : Length of front wing, 0.95 mm. ; 
width, 0.33 mm.; Length of antennae, about 0.25 mm.; length of hind 
tibia, 0.3 mm.; length of hind tarsus, 0.216 nun.; color, lemon yellow; 
feet and antennae, lighter; wings, immaculate, anterior margin of both 
paii-s. reddish. Eyes, brownish black. Antennae, seven jointed; joint 
1. very short, about one-third as long as second, subcorneal, distally 
somewhat obliquely truncate: joint 2, pear shaped, not quite twice as 
long as wide, oblique distally: joint 3, long, slender, as long as 4, 5, 
6, and 7 together, subcy lindrical. bearing distally on outer side a group 
of setae; 5 and 6, club-shaped; 7, somewhat fusiform, but tapering 
abruptly, distally bearing a terminal seta on distal oblique margin. 
Joints 3 and distad, coarsely ringed. 
Hind femur two-thirds length of tibia; tarsus about two-thirds 
length of tibia; distal joint of tarsus, excluding claw, two-thirds length 
of proximal: trochanter bearing two long setae on caudal side. Men- 
turn, three jointed: basal joint about as long as other two, gradually 
widening distally: second joint a 1 tout one-half as long as third; third 
joint tapering gradually to blunt point, which is tipped with black. 
Vasiform orifice, subcircular, as seen from above; operculum slightly 
Convex; concave on caudal margin, which is minutely setose; lingula 
protruding, gradually enlarged distally. minutely setose. Genitalia, 
usual. Eyes oblong, somewhat constricted near middle. In first pair 
of wings the main vein is long, extending nearly to tip. becoming 
gradually fainter from distal half. A basal veinlet arises from base of 
wing, and extends obliquely backwards to margin. Margins of both 
pairs of wings delicately beaded all around. A short row of seta' on 
cephalic margin of second pair at base, the distal two of which are 
three or four times longer than the others. 
$ . — Length about 0.5 mm.; proportionately smaller than female. 
Genitalia forcipate, the valves strongly curved at tip: penis tapering, 
a little more than one-half the length of valves, strongly curved 
upward, the strongest curve near base. 
This species is exceedingly abundant on the common papaw {Carioa 
papwva) at Miama. Florida. The under surface of the leaves of the 
plant are frequently quite covered with the pupa- cases, larva 1 , and 
eggs. The adults are also exceedingly abundant, usually resting on the 
under surface of the younger leaves. The different stages described 
from numerous specimens. Types in Div. Knt. Collection.
