970 LORD WALSINGHAM ON THE [Nov. 26, 



The lax^va feeds in mines, reminding one of those of the 

 bramble-feeding Tischeria margined Hw. on the upper surface of 

 leaves of Carlina salicifolia. I found it near Tacaronte, at 

 Guimar, and near Orotava — seven specimens were bred and one 

 captured.

 pecten. Palpi slightly recurved, white; terminal joint less 

 clothed, and therefore apparently rather more slender than 

 median. Head coarsely scaled above ; white. Thorax smooth,, 

 white. Foreivings white, sparsely dusted with brownish scales ; 

 a brown spot in the fold at about half the wing-length, and 

 another at the end of the cell ; a brown sti^eak along the termen,.

Tiji^e 5 (99045); d (99046) Mus. Wlsm. 



Hah. Tenerife : Santa Cruz, 12. 1 - 10. II. 1907, ^Symphytum 

 sp., 7-25. I, excl. 25. 1-20. II. 1907 {Wlsm.); Forest de la 

 Mina, 17. III. 1902 {Eaton) ; Guimar, 19. Ill - 10. lY. 1907 

 {Wlsm.); La Laguna, 1-6. IV. 1904 {Eaton). Thirty-three 

 specimens. 



Twelve specimens were bred from larvae, found at Guimar, 

 mining leaves of Symphytum ; the nrine almost undistinguishable 

 from that of Acrocercoj^s scalariella Z., but the pupa enveloped in 

 a white, silken, rather flat, ovate cocoon. Mr. Eaton caught a 

 single specimen of this species in the Forest de la Mina, in 1902 ; 

 in 1904 he met with it again, at La Laguna, and I took it on the 

 wing at Santa Cruz and Guimar.
