opening is between the bases of these mouth-hooks. Betweei 
the lobes below, and extending forwards into the mouth open 
ing is an oblong body, with a small lobe lying parallel to it oi 
each side, suggesting an imperfect labium with its palpi. 
The anterior stigmata are situated at the base of the seconc 
segment on each side. The peduncle seems to be often drawi 
into the fold of the suture. It is short, and expands into c 
fan-shaped transverse dilation, bearing on its outer margin si: 
small globose lobes in a semicircular row. In alcoholic speci 
mens this segment is uniformly more than twice as long on th< 
dorsal median line as on the ventral, causing the head to b 
directed downwards and forwards. 
The last segment is somewhat obliquely and sharply truncate 
shorter above than beneath, less smooth than the preceding 
segments. Below is a large wrinkled dark tawny prominence 
surrounding the transversely arcuate anal opening. The trun 
cation is surrounded by twelve small pointed fleshy tubercles 
disposed as follows: four equidistant larger ones on the lowe: 
margin, the ^middle pair the largest and triangular; above thesi 
four on each side at about equal distances. The upper pair 
one on each side, are slender and more distant from each other 
Of the remaining three on each side the middle ones are on tin 
margin of the truncation, but the other two are nearer the an 
terior margin of the segment, and may easily be overlooked 
On the ventral surface of the segment are four more; two dis 
tant ones just behind the anal prominence, and two placed closj 
together in the concavity just in front of the large middle paii 
of the marginal series. 
The posterior stigmata are situated on a pair of flat-topper 
tawny tubercles lying near each other, a little above the centei 
of the truncation. There are three slits on each tubercle, radi 
ating outwardly from a point near the inner margin. 
Puparium. (Plate II., Fig. 7.)—The puparium is shorter anc 
thicker than the larva, being four to five mm. long and about 
1.5 broad. It is fusiform, about equally and narrowly rounded 
at each end and reddish brown in color. The first two segments 
of the larval skin form a dark rugose convexity between th( 
two anterior spiracles, which are as in the larva. The posterioi 
tubercles are all present, but shrunken, surrounding the posterioi 
stigmata, which become a little more prominent. 
Imago. (Plate III., Fig. 1.)—The following is the descriptor 
of the female as given by Dr. Riley: ^ 
“Length 0.20 [inch (5 mm.)], alar expanse 0.38 [inch (9.5 mm.)] 
Antennae black; style microscopically pubescent; front, fulvous 
with a distinct, rather narrow, brownish cinereous margin; fact 
and orbits brownish white; palpi and proboscis black; ocellai 
area somewhat heart-shaped; thorax and abdomen pale yellow- 
brownish cinereous, with minute black points at the insertion ol
