14 THE CANADIAN ENTOMOLOGIST. 
Face pale lemon yellow (or yellowish stramineous), palpi of the same 
hue, each joint of the maxillary palpi tipped with dark purple, the labial 
palpi thickly dusted with dark purple and with a wide dark purple annulus 
close to the tip. Vertex dark purple, with pale lemon yellow intermixed 5 
antennae pale lemon yellow, faintly annulate with purple at the base, 
towards the apex purple, faintly annulate with pale lemon yellow. ‘Thorax 
dark purple, with a narrow pale lemon yellow median longitudinal stripe, 
anda wider and more distinct one on each side above the wings, and a 
dark purple spot before the wings. Primaries pale lemon yellow and dark 
purple ; the dorsal margin is dark purple from the base to near the ciliae, 
where the purple widens over the apical portion of the wing, except a small 
lemon yellow spot on the edge of the costal ciliae before the apex ; costal : 
margin from the base to the basal fourth dark purple; from the basal’ 
fourth of the costa a rather wide fascia passes obliquely backwards from 
the costal purple to the dorsal purple, uniting them, and thus enclosing on 
the base of the disc an oblong pale lemon yellow spot. Immediately 
behind the oblique purple fascia, the dorsal purple is excavated, and the 
wing is pale lemon yellow to the costa and as far back as the ciliae, with a 
little purple dusting or row of small purple spots along the extreme costa 
before the ciliae. Sometimes there is a faint golden or stramineous patch 
in the purple at the extreme apex, and sometimes the apex is a little 
dusted with golden or stramineous, Ciliae golden or stramineous, with 
three wide dark purple hinder marginal lines, one at the base, one in the 
middle, and one at the tip. (Perhaps they might be better described as 
dark purple, with two shining stramineous hinder marginal lines, one before 
their middle and one before their tip.) | Posterior wings and ciliae dark 
purplish fuscous. Anterior and middle legs yellowish mixed with purple 
behind, dark purple in front except the tarsi, which are silvery white with 
each joint tipped with purple. Posterior legs yellowish except the apical 
half of the outer surface of the femora, the tips of the tibiae behind, and 
the tip'of each tarsal joint. Thorax and upper surface of the abdomen 
dark purple; venter pale lemon yellow. In some lights what I have 
called dark purple appears violaceous or iridescent, and the stramineous 
portions appear golden or sulphur yellow. A/. ex. 35in. Kentucky. 
Dr. Clemens received his specimen from Virginia. I have bred it 
from the leaves of the Black Walnut { Fuglans nigra). It mines the 
upper surface, and, when first taken, was supposed to be the mine of a 
Philocnistis, containing a pupa. It was something more than an inch 
long, a little crooked, very narrow, and resembled a small snail’s track.
