NORTH AMERICAN LERIIK^PTERA.

This genus has a very decided hahital resemblance to Orfhodes, 
but differs at once by the naked eyes. The species u]jon which tlie 
genus is based has been known to me for .several years. It is in the 
collection of the United States National iNluseum, taken as far back 
as 1882, and I have received it for name several times. I have tried 
to identify it with all genera or species to which it could have been 
reasonably referred, but cannot find any description to cover it, nor 
do I find it named in any collection thus far examined. It may be 
confused under Orthodes cxjnica, to which it bears some resemblance. 
I have named the form. 
Aiiorf liodes prima n. sp. — General color a soft, even mouse gray. Head 
and tliorax immaculate. Primaries with all the lines evident, the basal, t. a. 
and t. p. single, line, blackish, the s. t. broader, pale. Basal line nearly strait^ht. 
T. a. line with a decided inward angle on the cell, irregularly oblique below. 
T. p. line outcurved over cell, somewhat incurved below; it is even or sli<Thtlv 
crenulated. S. t. line yellowish, irregular, as a whole closely parallel to the outer 
margin. A vague blackish median shade line, often ditfuse, obtusely angulate 
on the reniform, quite rigid below to the hind margin. Claviform wautino-. 
Orbicular punctiform blackish. Keniform an indefinite blackish lunule. some- 
times not distinct, marked with a few whitish scales. A very faint, yellowish 
terminal line. Secondaries very faint smoky gray, shining. A vague discal 
lunule and a very distinct yellow line at the ba.se of the somewhat paler fringes. 
Beneath, glistening gray, powdery, somewhat darker on primaries, both wings 
with a variably complete and distinct outer line and discal lunule. Expands 
1.12—1.20 inches. 28—30 mm.

September 2d and 12th (U. S. Nat. Mus.) ; Columbus, O. (Tallant). 
Under the number 3503, bred specimens are in the biological col- 
lection (coll. C. V. R.) and the life-history has been made out. 
There should be no difficulty in recognizing this species by the 
soft color and single, line median lines. The harpes are broad, up- 
curved at tip, a small corneous process at inferior angle, where also 
the surface is set with acute teeth ; a stouter and longer corneous 
spur from below the middle of the harpe inclined upward and in- 
ward, or exactly opposite the other spur.

Triclioelea po*$tica n. sp. — Pale, somewhat creamy white, with a faiut 
luteous admixture, powdery. Primaries with all the maculation faintly written, 
blackish. Basal line marked on costa by a geminate black spot, and again faintly 
below the median vein. T. a. line upright, geminate on costa only, lunulate, 
preceded by a variably obvious pale shade. T. ]). line also marked by costal 
dots, thence single, crenulated, outcurved over reniform, rather evenly oblique, 
or with but a slight incurve below. This line is also accompanied by a somewhat 
paler shade, and a series of pale venular dots outwardly. S. t. line marked on
