3539 : 1. — EUIGETHKS STltOBILACEI, sp. tl. 



Antennae yellowish white, annulate with pale olive-grey. Pafpi whitish, 

 shaded with olive-grey. Head whitish. Thorax dull yellowish white, mottled with 

 pale olive-grey. Forewings yellowish white, speckled and mottled with olive-grey, 

 becoming darker or more fuscous in certain spots ; these are indistinctly separable 

 from the profuse speckling which commences a little beyond the base, three are 

 placed on the line of the fold at equal distances, the outer one being a little beyond 

 the middle of the wing ; there is also a small spot about the flexus, another beyond 

 the end of the cell, and the speckling about the end of the termen is somewhat 

 grouped, with intermediate pale spaces at and below the apex, it is also partly dis- 

 tributed through the pale whitish cinereous cilia. Exj). al. 10 — 13 mm. Kind- 

 wings very pale bronzy grey ; cilia shining, pale bronzy cinereous. Abdomen 

 olivaceous fuscous, anal tuft shining pale cinereous. Legs whitish, faintly banded 

 witii olive-grey.

ITab. : Biskra, 25.III — 21.IY.1903 ; Hammam-es-Salahin, 16.III. 

 — 25.1V.1904, 25.III. — 14.V.1903. Larva Ralocnemon strohilaceum, 

 16.11. excl., 22.IV.1908 (96500). Thirty-two specimens. 



The species is extremely abundant toward the latter end of 

 March and in the beginning of April amongst Ralocnemon strohi- 

 laceum, on wliich the larva feeds. 



The larva was not described at the time, and having since failed to 

 breed other specimens, I cannot be sure that larvae found abundantly 

 in 1904 on the same plant belong truly to this species.

('aTToo-Ti/Siys = solitary). 



Tgpe, (^ $ , Apostibes griseolineata, Wlsm. 



Antennae (|) <J shortly biciliate ; basal joint enlarged and thickly clothed, with 

 a well-developed pecten. Ocelli absent. HausteUuni moderate, scaled. Maxillary 

 £alpi short. Labial Palpi slender, smooth ; terminal joint erect, shorter than 

 median. Head and Thorax smooth. Foreioings lanceolate, evenly tapering to an 

 acute apex : Neuration 11 veins, 7 and 8 coincident, to costa ; 6 and (7-1-8) stalked ; 

 the rest separate ; 1 furcate at base. Hindwings (i) evenly attenuated to a some- 

 what less produced apex than in the forewings : Neuration 8 veins, all separate ; 5 

 straight, midway between 4 and 6 ; discoidal angulated inward to media between 5 

 and 6, nearly obsolete between 6 and 7. Abdomen smooth. Legs : hind tibiae 

 hairy. 



Allied to Scythris, Hb., but differing in tbe veins of the hind- 

 wings being all separate, thus agreeing with the Australian species 

 which Meyrick refers to Scythris. 



It is possible that Scythris may present such variation of neura- 

 tion within the same species, but until this has been ascertained it
