. The larva is greenish, with dark green contents, but just before becoming 
a pupa, it changes color, becoming bright crimson. It pupates in a small 
nidus on the ground. 
I am able to describe the imago only from a specimen which emerged 
from the #idus, but was unable to rupture the pupal envelope, which I 
removed after its death. In this specimen, the head and thorax appeared 
to be white with a blackish spot on the labial palpi, and a wide longitu- 
dinal blackish streak on the thorax. The wings are shining dark brown 
or black, with purplish reflections, with a dorsal basal white streak ending 
in a white spot nearly opposite, but a little behind which, is a small costal 
white streak, behind which again is a long oblique costal white streak 
reaching almost to the dorsal margin. There is another costal white 
streak just before the ciliæ. A/ar ex. a little more than % inch. The 
colours and their arrangement do not differ very greatly, therefore, from 
Dr. Clemens’ two species of Parectopa above mentioned. Kentucky. 
Gracillaria plantaginisella. LN. sp. 
In this species the labia] palpi, which are very long, have the second 
joint not tufted, but clothed below with long loose scales. They are white, 
with a golden brown stripe beginning on the apex of the second joint 
beneath, and extending along the under side of the third to the apex. 
Maxillary palpi white, tipped with brownish. Antennæ pale brownish, 
iridiscent ; face opalescent ; vertex brownish golden with a silvery white 
stripe on each side extending back over the sides of the thorax, which is 
brownish golden. Anterior wings brownish golden or deep red orange, 
according to the light, with a longitudinal median white streak near the 
base, but not touching it, in some specimens; in others reaching the base, 
and seeming to be a continuation of the white lateral thoracic streaks. 
Four costal and three dorsal silvery white (in some lights bright metallic) 
streaks, each of which is dark margined on both sides and around the 
apex, and the dark margins slightly powdered posteriorly on the 
disc, those of the third and fourth costal, and second and third 
dorsal, being confluent with each other and with the brownish portion 
of the apical part of the wing. The first costal is at about the basal 
fourth, is the largest, is a little oblique, and produced along the costa 
towards, but not to, the base. The first dorsal opposite the space 
between the first and second costal; the second and third dorsal 
nearly opposite the third and fourth costal respectively ; the second 
and third costal a little oblique backwards; the fourth costal and
