1907.] MICROLEPIDOPTERA OF TENERIFE. 969 



14. Y. 1907 (IF/sm.); La Lagima, 23. Y. 1907 {msm.); Las 

 Mercedes, 29. Y. 1907 (Wlsm.). Nineteen specimens. 



Not uncommon, on the highei' ground, in the barranco above 

 Realejo and elsewhere ; first taken by Mr. Eaton, in the forest 

 of La Mina. It is very near to alhidella Tngstr. (1847; =r1iyn- 

 cliospordla Stn., 1848), but differs in the possession of two extra 

 spots beyond the conspicuous plical one : the European species 

 having no spot at the end of the cell or below the costa. Yein 5 

 is absent in both wings. 



39, (417'01) POLYMETIS, gn. n. 

 (/ToXu^Tj-is =of-many-counsels.) 



Type Polyvietis carlinella Wlsm. 



Antennae |, slightly serrate towards apex ; basal joint with 

 strong pecten. Maxillary Palpi short. Lahial Palfi smooth, 

 usually dependent, but capable of upward movement ; terminal 

 joint shorter than median, rather obtusely pointed. Haustellum 

 small. Head and face coarsely, almost roughlj^, scaled. Thorax 

 smooth. Foreioings evenly lanceolate: neuration 12 veins; 

 7 and 8 stalked, 7 to costa ; 6 out of 7, to termen ; 5 out of 

 stalk of (6 + 7 + 8): rest remote, 3 slightly approximate to 4; 

 1" distinct, 1 furcate at base. Hindwings nearly |, tapering 

 evenly to an acute apex ; cilia 2-2 1 : neuration 7 veins, 5 and 4 

 coincident ; 6 and 7 stalked, enclosing apex ; 2 remote from 3, 

 which is somewhat approximate to (4 + 5) ; above 5 the discoidal 

 recedes to radius. Abdomen smooth. Legs, hind tibiae hairy. 



Almost corresponding in neuration with some species of Aplie- 

 losetia Steph. and Stagmatophora HS. ; separated from the former 

 by the basal furcation of vein 1 of the forewings, as well as by 

 the shorter and less recurved palpi, and from the latter by the 

 same characters, and by the coincidence of veins 5 and 4 of the 

 hindwings. The habits of the larva afford additional reason for 

 sepaiuting Polymetis from Aphelosetia (Elachista Auct.), of which 

 the larvae of all known species feed on the Gramineae, or 

 Cyperaceae. 



80. (3920-1) Polymetis carlinella, sjd. n. 

 (Plate LII. fig. 13.) 



Antennae and Paljn whitish cinereous. Head white. Thorax 

 whitish cinereous. Foreioings white, profusely and evenly dusted 

 throughout with pale greyish brown scales ; the outer half of the 

 cilia whitish cinereous. Exp. al. 10-11 mm. Hindioings ^rej ; 

 cilia pale brownish cinereous. Abdomen greyish. Legs whitish, 

 with faint greyish shade-bands on their outer sides. 



Type 6 (99037) ; $ (99038) Mus. Wlsm. 



Hab. Tenerife — Tacaronte, and Guimar, sup. Carlina 

 salicifolia, 19. II - III, excl. 13. Ill - 23. lY. 1907; Puerto 

 Orotava, 27. lY. 1907. Eight specimens.
