fissure extends to a little more than the wing-length ; the cilia of 

 the tornar lobe, and of the lower margin of the apical lobe, dis- 

 tinctly straw-white on their basal half and smoky blackish on 

 their outer half (this distinct division in the basal and distal 

 colouring of the cilia is in itself amply and uniformly sufficient to 

 separate jxirticiliata ivom tetradactyla L., in Avhich the cilia are 

 darkened throughout). Ex2y. al. 20-22 mm. Hindwings brownish 

 ochreous ; cilia of all the lobes smoky fuscous on their costal 

 margins, whereas on their dorsal margins the basal two-thirds ai-e 

 straw-white, the distal third only fuscous. Abdomen whitish, 

 especially at the base, with a narrow dorsal, and wider lateral 

 brownish grey lines. Legs white.

Hah. Tenerife: Santa Cruz, 23. XII - 12. 11. 1907; Puerto 

 Orotava, 21. TV. 1907. Fifteen specimens. 



Having mistaken this species in the field for tetradactyla L., no 

 special search for the larva was undertaken, but T strongly suspect 

 that two green and slight]}' hairy larvae found on Lavandtda abro- 

 tanoides at Santa Cruz, which I unfortunately failed to rear, must 

 have belonged to it. 



Rebel records worn specimens of Acvjytilia tetradactyla from 

 Pedro Gil (Tenerife, 1600 m., 30. VII. 1889 — Simony), and from 

 Giun Canaria [Eichter). As Pedro Gil is on very high ground the 

 date is not surprising, but it is at least probable that these speci- 

 miens (which I have not seen) belong to the same species which 

 occurs so abundantly at Santa Cruz in January and February, and 

 of which I have a single specimen taken at Puerto Orotava on 

 April 21st. I certainly thought the species was tetradactyla when 

 I took it, indeed I should have secured more specimens had T then 

 recognised it asTiew. 



6. (1365 "2) Alucita hesperidella, sp. n. 



Antennae pale brown, speckled with white. Falpi short, porrect, 

 slender, scarcely projecting beyond the face ; pale brown. Head 

 and Thorax pale buff-brown. Forevnngs pale buff-brown, the 

 costa narrowly white, more consjjicuously before the apex, a small, 

 oblique, inverted darker greyish streak a little beyond the middle 

 (sometimes obsolete) ; the fissure extends approximately to half 

 the wing-length, the tornal lobe being white along its upper half 

 from the base of the fissure to its apex, the cilia tinged with 

 brownish grey, as also are those of the apical lobe. Ex2). al. 16-18 

 mm. Hindwings pale greyish brown ; cilia the same, becoming 

 whitish at the apex of the tornal lobe. Abdomen pale greyish 

 brown, with whitish dorsal line. Legs white, a slender greyish 

 line along their outer sides.
