Type 2 (66513); ¢ (66514) Mus. Wlsm. (Godm-Salv. Coll.) BM. 
Hab. Muxico: GUERRERO: Amula, 6000 ft., VIII. (7. H. Smith). Two specimens. 
12. Tortrix ponera, sp. n. 
Antennae rather densely biciliate; fuscous. Palpt porrect, extending rather more than the length of the 
head beyond it ;. brownish cinereous, the median joint moderately clothed above and beneath; terminal 
joint smooth, about two-thirds the length of the median. Head and Yhorax brownish cinereous. 
‘urewings narrow, elongate, with slightly convex costa, rounded apex, and scarcely sinuate, oblique 
termen; coppery reddish, with a pale, silvery, greyish white streak commencing at the base, slightly 
widened outward along the cell, where its upper edge is slightly angulated about the middle, and fading 
out a little beyond the end of the cell, in the direction of the termen below the apex; along the upper 
edge of the cell, and along the costa before the apex, the tawny red tinge is rather intensified, as also in 
a small patch about the lower angle of the cell; cilia pale silvery greyish, with a slightly darker shade, 
preceded by a slender whitish line along their base. Awp.al. 25mm. Hindwings very pale brownish 
grey; cilia even paler. Abdomen greyish. Legs whitish cinereous. 
Type 3 (6047 Wlsm. Det. 1908) US. Nat. Mus. [PZ'7' (38946-7) Mus. Wlsm. BM.] 
Hab. Mexico; mexico: Popocatepetl, 13,000 ft., VI. 1906 (W. Schaus). Four

The specimens are not in very good condition. 
18. Tortrix dichroaca, sp. n. 
Antennae biciliate 1; dull brownish ochreous. Palpi projecting the length of the head beyond it; dull 
brownish. Head dull brownish ochreous. Thorax tawny chestnut. Forewings divided into two equal 
parts by an oblique rich chestnut-brown fascia, from before the middle of the costa to beyond 
the middle of the dorsum, somewhat dilated outward on its lower half, its inner edge moderately 
straight, its outer edge sinuate, both narrowly margined by ochreous lines; before this fascia the basal 
half of the wing is dull leaden grey, with a faint indication of a basal patch containing chestnut-brown 
spots and streaks, especially below the fold; beyond the fascia the outer half is pinkish fawn-colour, 
with a triangular rich chestnut-brown costal patch, halfway between the fascia and the apex; cilia 
corresponding in colour to the outer half of the wing, but containing a dark grey patch below the apex, 
and tending to become ochreous at the tornus. Ewp. al. ¢ 17-5, 219mm. Hindwengs and cilia dirty 
whitish, with some faint grey shades and mottling. Abdomen and Legs whitish cinereous.

14. Tortrix impositana, sp. n. 
Antennae, Palpi, Head and Thorax fawn-ochreous ; the latter with posterior tuft of raised brown scales. 
Forewings with the costa arched at the base, slightly sinuate beyond the middle, termen sinuate ; fawn- 
ochreous, with fawn-brown markings; a brownish shade on the lower half of the base, with a conspicuous, 
truncate, blackish dorsal patch, reaching from the flexus to one-third, seeming to indicate the remains of 
the usual basal patch, limited by a slender outwardly oblique line from the costa at about one-fourth; an 
oblique fascia commences on the middle of the costa, its outer side only being darkly shaded up to the 
costa, its inner width indicated by a slender line; on the cell the brown shade becomes widened and 
continues of even width to the dorsum before the tornus, where it carrics some black sprinkling; before
