GELECHIA. 67 
commencement of the costal cilia precedes an outwardly angulate unsprinkled band of the pale ground- 
colour, beyond which the apical and terminal portion of the wing is slightly shaded ; there is a small 
fuscous dot in the fold, below the apex of the costal triangle, and another at the end of the cell; cilia 
whitish, minutely sprinkled with fuscous. Zep. al.10 mm. Hindwings shining, pale grey ; cilia pale 
greyish cinereous. Abdomen shining, pale greyish; anal segment inclining to ochreous. Legs: hind 
tibiae and tarsi banded with cream-white and greyish fuscous. 
Type 3 (65661) Mus. Wlsm. (Godm-Salv. Coll.) BM. 
Hab. Mexico: Guerrero: Amula, 6000 ft., VIII. (Z. H. Smith). Unique. 
20. Gelechia creberrima, sp. n. 
Antennae brown, distinctly annulate with whitish cinereous. Palpi recurved, the terminal joint nearly as 
long as the median, roughened beneath ; both profusely speckled with brown and whitish cinereous. 
Head and Thorax brown, thickly speckled with whitish cinereous. Forewings reddish brown, profusely 
dusted with whitish cinereous, which is especially concentrated around the margins of a large, somewhat 
triangular, brown costal patch before the middle, reaching nearly to the fold, on which is a small spot of 
the same colour, a less conspicuous discal spot lying above and beyond it; a small pale cinereous spot 
occurs on the costa at three-fourths from the base; cilia pale cinereous, dusted at their base and along 
their middle with brownish fuscous. Hap. al. 13 mm. Hindwings shining, pale bone-grey, dusted at 
the apex on the underside ; cilia pale brownish cinereous. Abdomen brownish grey; anal tuft inclining 
to ochreous above, pale cinereous externally. Legs brownish fuscous, banded with pale cinereous, tarsi 
spotted with pale cinereous; middle tibiae with two fan-like tufts in the ¢. 
Type & (65658); 2 (65659) Mus. Wlsm. (Godm-Salv. Coll.) BM. [PT. (65660) US. Nat. Mus. ] 
Hab. Mexico: Guerrero: Amula, 6000 ft., VIII-IX. (H. H. Smith). Three 
specimens. 
The costal patch in some specimens ( 2 65659) is ill-defined and diffused outwards 
on the margin. 
21. Gelechia impurgata, sp.n. (Tab. IT. fig. 23.) 
Antennae white, dotted with fuscous above. Palpi white, slightly and minutely sprinkled with fuscous. 
Head and Thorax cream-white. Forewings cream-white, with a conspicuous fuscous blotch, obliquely 
placed on the cell, somewhat diffused at its outer end, but broken into scattered scaling which unites 
again in an elongate median streak beyond the end of the cell; the apex and termen are also dusted 
with fuscous; cilia white, sparsely dusted. xp. al, 14mm. Hindwings and cilia pale brownish grey. 
Abdomen white, with an ochreous tinge. Legs white, sprinkied with fuscous. 
Type Q (35636) Mus. Wlsm. BM. 
Hab. Mexico: sonora: 1883 (H. K. Morrison). Unique. 
22. Gelechia synthetica, sp. n, 
Antennae blackish. Palpi blackish, slightly pale-speckled. Head cinereous, speckled with black. Thorav 
blackish, with minute pale speckling. Forewings of even width, with rounded apex; blackish, with a 
slight purplish tinge and minute hoary speckling, except where black spots, each accompanied by some 
brownish ochreous scales, are distinguishable from the less intensely dark wing-surface ; of these spots 
the first is on the costa at one-fourth, placed rather obliquely, with a narrow ochreous subcostal line 
reaching it from the base ; another lies nearer to the base on the upper edge of the fold; a third, with 
some ochreous scales preceding and following it, lies in the fold a little before half the wing-length, and 
this is almost connected with a discal spot above it ; another triangular black spot, with ochreous scales 
along its inner edge, is at the end of the cell, beyond which a short, curved, ochreous costal streak precedes 
the pale brownish cinereous cilia which are dusted with fuscous. Exp. al. 11-12 mm. Hindwings leaden
