Rob.: ALGERIA— Biskra, 11-13.III. 1903. Two specimens. 



This has very much the appearance of some of the species as- 

 sociated with Tamarix but was taken at some distance from anj^ 

 growth of this plant. 



2587 : 1. — Gelechia cerostomatella, sp. n. 



Antennae brownish grey above, pale ochreous beneath. Palpi with the median 

 joint coarsely scaled beneath, terminal as long as the median, smooth, acuminate ; 

 whitish ochreous, the median with a dark brown patch near its base, the coarse 

 scales tinged with fawn-brown beneath. Head whitish ochreous. Thorax pale 

 fawn-ochreous, with a dark smoky brown line down the middle, and a brown spot 

 at the base of the tegulae. Foreiolngs long, narrow, with the costa straight, the 

 apex slightly depressed, obtusely rounded, but narrow owing to the wing being con- 

 stricted outward by gradual elevation of the dorsum, clothed with somewhat un - 

 usually broad flattened scales ; in colouring like some varieties of Cerostoma radia- 

 tella, Don., a dark smoky brownish fuscous band runs from the middle of the base 

 to the apex and termen, slightly widening outward, its edges clearly defined and 

 without irregularities, below it the dorsum is pale fawn including the whole space 

 beneath the fold, except where a few scales of the dark band above slightly overlap 

 it toward the base ; the costal area narrow at the base and slightly widening out- 

 ward, is pale pinkish ochreous, except the extreme costa which is nearly white, very 

 narrowly so, but rather more conspicuously, where it includes the costal cilia ; at 

 the apical end of the dark brown band is a sliglit bronzy patch, shining in some 

 lights ; terminal and apical cilia smoky fuscous ; underside shining pale ochreous, 

 with silvery reflections along the middle. Exp. al., 19 mm. Hindivings (2) tra- 

 pezoidal, with rather rounded costa, produced apex, slightly emarginate termen, 

 straight dorsum, and well-defined tornus and flexus ; pale iridescent rosy grey ; 

 cilia (f) pale shining brownish grey ; underside shining pale grey, the costa pale 

 ochreous. Abdomen and Legs pale brownish ochreous.

Hah. : ALGERIA— Biskra, I3.IV.1903. 



This most distinct and interesting species is perhaps most nearly 

 allied to interruptella, Hb., but the shape of the forewings is very 

 different. I took a single specimen at light in the town of Biskra on 

 April 13th. 



2611 : 1. — GelECHIA NIGROROSEA, sp. 11. 

 Antennae cinereous, narrowly barred with black above. Palpi pale I'osy cine- 

 reous the terminal joint with two black bands, the median touched with black at 

 its base and bright rosy red at its apex, the brush beneath also rosy. Head and 

 Thorax rosy fawn, speckled with fuscous. Forewings rosy fawn, speckled with 

 fuscous, with a fuscous ill-defined spot on the disc, another at the end of the cell ; 

 above and below the latter are two marginal fuscous shades before an indistinct 

 band of the paler ground-colour which is further displayed by a fuscous shade to- 

 wards the apex, near the base is a slightly oblique series of three black spots
