796 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
the scrub pines (P. inoj)s) around Washington. These larvae were bred 
to the perfect state and proved to be the same species. 
'•A leaf-miner of precisely tin- same habits and of almost the same 
appearance was found tin- past winter in the leaves of the southern 
pine {P. auttraHs) at Macon, Ga., a point where, owing to a sudden fall 
of some 400 feet in altitude, the northern and southern floras meet in 
a remarkable manner. Progressing southward, a careful search was 
made for additional specimens of this leaf-miner, but none were found 
except in this one locality. Assuming the identity of the two forms 
(they have since been bred and proved identical), it puzzled us for some 
time to discover how the species could have reached P. australis, since 
the southernmost limit of P. inops is South Carolina, and P. rigida is 
essentially northern. It was not until we discovered the same miner 
in leaves of the yellow pine (P. mitts) that we were able to solve the 
problem. The yellow pine is not ouly found north, but also extends 
south until at Macon, Ga., we cau see it mingling with the northern- 
most specimens of P. australisS (Comstock.) 
Moth. — Palpi simple; hind wings excised beneath the tips. Head white, flecked 
with scales of the general line of the insect, which may be called a brownish-yellow. 
Palpi white: the second joint longer than the third, brownish-yellow flecked with 
fuscous scales on the outer side ; third joint white, with a brownish-yellow annulus 
about its middle, and another near the tip; antenna? white, each joint crossed by a 
brownish band. Thorax and forewings of the general hue above mentioned, flecked 
with fuscous scales. On the forewings are three white fascia?, placed respectively 
at about the basal, middle, aud apical fourths of the wing length ; the apex is densely 
dusted with fuscous on a white ground, and the dorsal margin is sparsely flecked 
with brown. The fasciae also are more or less margined with brown scales, and the 
third one is sometimes interrupted in the middle : aud the fuscous scales which mar- 
gin the first aud second fascia? (especially along the second, near the fold) form 
minute tufts of raised scales. Cilia grayish, with interspersed black scales, which 
are tipped with white. Under side of the forewings brownish. Hind wings pale 
grayish with white cilia: abdomen brown above, whitish toward the apex beneath. 
Expanse of wings three-eighths inch. (Chambers, in Comstock's Report.) 
Egg. — Seen from above, appears globular, with a diameter of 14 mm ; seen from the 
side, appears so compressed that its long diameter is nearly twice the length of the 
short. Color reddish brown. Surface marked with delicate, close, meridional carina?, 
meeting at the center above aud below. (Comstock.) 
Larva.— Length when full grown, 4. 2 mm ; average width, .58 mm . Sub-cylindrical; 
all segments except head and anal segment nearly equal iu diameter, the exceptions 
smaller. Color yellowish brown ; head, prothoracic and anal plates dark brown ; 
mouth-parts yellowish : prothoracic shield strong, completely divided longitudinally 
in the middle by a moderately wide suture. (Comstock.) 
Pupa.— Length, 4.4 mtE ; average width, .71 mm . Head obtusely rounded ; wing- 
sheaths extending to sixth abdomiual segment : autennal sheaths reaching nearly 
to end of wing-sheaths, all compactly soldered. General form very nearly cylin- 
drical : sixth and seventh abdominal segments spreading at posterior borders ; dor- 
sal side of anal segment furnished with a cluster of from 10 to 15 delicate tentacu- 
lar or hook-formed lilameuts. Color, when fast transformed, light yellow brown, 
soon changing to very dark brown, almost black, on head, thorax, wings, and crural 
sheaths; abdomen of a lighter brown, growing still lighter towards the anus. 
Parasites. — A minute chalcid parasite was bred from the specimens found in P. 
rigida. From S to 12 of the larva- of this parasite are usually found within the
