Hab. : ALGERIA — Biskra, Larva Rhus dioica, 20.11, cxcl. 

 29.111 — IG. I V.190;3; El-Kantara, Larva 27. IV., excl. 28.V.1903. 

 Eleven specimens. 



1 found the larvae feeding between leaves of Shut! dioica at 

 Biskra, February 20tb, and at El-Kantara in April. The type emerged 

 March 29th ; other specimens were also bred but none were taken on 

 the wing although I frequently searched for them. Like many other 

 Biskra things it seems to be double or even perhaps treble brooded. 

 Allied to diffinis, Hw. 



2740 : 1.— Gelechia heligmatodks, sp. n. 



Antennae fuscous, with pale annulations. Palpi whitish ochreous, the terminal 

 joint broadly banded and shortly tipped with fuscous. Head a,\\A Thorax h\'\g\it 

 ochreous ; tegulae fuscous. Foreioi.ng-t greyish fuscous through a profuse sprinkling 

 of hoary cinereous scales upon the dark ground-colour ; the doi'sum from the base 

 to the tornus is bright ochreous, this colour throwing a slight angular projection 

 across the middle of the fold, where it is clearly defined against the rather intensified 

 dark shade above it, which is thus thrown into two obtuse angles, much after the 

 pattern so well known in Plutella macuUpennis {cruciferarion) ; this bright ochreous 

 colour shows also below the costa near the base, and along the termen, especially to- 

 ward the apex, and is again noticeable on either side of a black dot about the lower 

 angle of the cell, touching the upper corner of a rather brownish patch above the 

 tornus which blends with the greyish fuscous shading above it in which there are 

 three short whitish ochreous ill-defined costal spots before the apes ; cilia mottled 

 with greyish fuscous and whitish ochreous, a slender fuscous line running through 

 them near their tips and a darker line, almost black, along their base. Exp. al., 

 14 — 15 mm. Hindioings grey, with a brownish tinge ; cilia brownish grey. Abdo- 

 men brownish grey. Lecfs whitish ochreous, with two tibial and five tarsal fuscous 

 bands externally.

 the base in that s])ecies.
