Hab : ALGERIA— El-Kantara, 3.V.1903, 



Six apeclmcns taken on the higher slopes of the mountain near 

 the railway, but scarce. An inconspicuous species, but differing from 

 any with which I am acquainted. 



2538 : I. — Gelechia lacertella, sp. n. 



Antennae greyish fuscous, with faint paler annulations. Palpi with well- 

 developed coarse brush beneath ; cinereous, much sprinkled with greyish fuscous. 

 Head and Thorax pale greyish ochreous, with a few pale fuscous scales. Forewings 

 pale greyish ochreous, profusely sprinkled with greyish fuscous which becomes 

 darker, almost black, in a costal spot near the base, a plical spot a little beyond it, 

 a second more conspicuous plical spot at about two-fifths, a small discal spot above 

 and a little beyond the last, a small spot at the end of the cell, and a dark costal 

 shade preceding a broken transverse band of the pale ground-colour, less sprinkled 

 with darker scales than the remainder of the wing-surface ; cilia pale greyish 

 ochreous, profusely sprinkled with fuscous, except at their tips. Exp. al., 18 — 20 

 mm. Hindwings, costa ciliate throughout, cilia very long towards base ; shining, 

 brownish grey ; cilia brownish cinereous. Abdomen shining, brownish grey. Legs

Type, c? (88984) ; ? (88990) ; Larva (88992). Mus. Wlsm. 



Rah. : ALGERIA— El-Kantara, 4-25.V.1903. Larva Acan- 

 fJti/Uis armnta, 6.V, excl. 25. V — 30.VL1903. Nineteen specimens. 



This species is extremely common in the dense tufts of Acan- 

 thyllis armata on the sides of the low hills. The larva makes a web 

 along the stems and 1 should strongly recommend a pair of thick 

 leather gloves to any one who desires to collect them upon this most 

 forbidding plant. The larva has a black head and a broad black j)ro- 

 notal plate of even width, the pro- and meso-thoraoic legs are black, 

 the metathoracic corresponding to the colouring of the segments ; 

 yellowish white with two dorsal and two subdorsal lines of pale 

 brown. 



Apparently nearly allied to pinguinella, Tr., but it is a smaller 

 insect with wings proportionately shorter. The markings and colour- 

 ing are also extremely similar but by no means identical.
