102 ENTOMOLOGICAL NEWS. [March, ’o8 
There is a short dorso-basal white streak, somewhat dilated posteriorly. 
The median basal streak is curved downwards, and extends for two- 
fifths of the wing length, where it is confluent with the first dorsal 
streak, its upper edge uniting with the apex of the first dorsal streak. 
A few dark brown scales extend around the apex of the angle thus 
formed. There are four costal and three dorsal white streaks. The 
first dorsal streak at the basal fourth is very large, oblique and curved. 
Internally, it is dark margined just before it unites with the basal 
streak, the dark margin being continued around the angle and for a 
short distance along the lower side of the basal streak. The extreme 
edge of the costa is dark brown for about one-third of the wing length, 
where the dark line is deflexed, and continues as the dark margin of 
the first costal streak which is narrow, very oblique, its apex extending 
to a point just beyond the apex of the first dorsal. The second costal 
streak is large, nearly perpendicular, its apex opposite to that of the 
second dorsal streak, which is also very large, and placed slightly nearer 
the base than the corresponding costal streak, and is somewhat oblique. 
The next pair of streaks, of which the dorsal is placed just above the 
tornus, are nearly opposite to each other, slightly oblique toward the 
base and curved; their apices nearly meet. These two pairs of streaks 
are margined internally with brown scales. Fourth costal streak oblique, 
cuved and unmargined. A narrow line of black scales extends from 
below the apex of the last costal streak to near the apex of the wing, 
and is margined above by a line of white scales. Marginal line in the 
cilia dark brown, extending around the apex from the fourth costal 
streak to the third dorsal. Cilia grayish ocherous. Alar expanse 7 mm. 
Hindwings grayish. Cilia gray, with a fulvous tinge. Abdomen dark gray 
above, whitish beneath. Anal tuft grayish ocherous. Legs whitish, 
banded and striped with gray. 
The unique type, a male of this species, was bred by Mr. W. 
D. Kearfott from a much wrinkled mine on the underside of a 
willow leaf, collected in Essex County Park, N. J., July 6, 1902. 
The imago appeared July 19. 
This species is nearest to L. scudderella Frey & Boll, which 
it closely resembles in the costal and apical markings. 
Lithocolletis tremuloidiella sp. nov. 
Antenne dark gray, the joints becoming lighter toward their bases. 
Palpi grayish white. Face grayish white. Tuft gray, mixed with white. 
Thorax pale reddish brown near the base, becoming more ocherous be- 
yond the middle. There is a short median basal white streak, and a 
dorso-basal white streak, both thickly dusted with blackish scales, and 
uniting with the first dorsal streak. There are five costal and five dorsal
