1010 LORD WALSINGHAM ON THE [I^OV. 26, 



Exp. (d. 3-4"25 mm. Hindioings and cilia pale leaden grey. 

 Abdomen gre}. Legs pale grey. 



Type 2 (99201); 6 (99202) Mus. Wlsm. 



Eab. Tenerife : Puerto Orotava, Statice piectinata., 4. Y, 

 excl. 29. Y - 21. YI. 1907 ; La Lagmia, 20. Y. 1907. Thirteen 

 specimens. 



Perhaps most nearly allied to helianthemella HS., but the head 

 is ochreous, and there is no pale fascia in either sex : the 

 antennae are long, and there is no dark dividing line in the 

 cilia. 



Bred from larvae mining the leaves of Statice peciinata : the 

 green larva, making small, tortuous, mines in the little leaves, is 

 fairly abundant, but very inconspicuous ; the cocoon is whitish. 

 The mines were collected at Puerto Orotava ; a single specimen 

 taken on a table in the hotel at La Laguna probably escaped from 

 my bottles. 



142. (4368-2) Stigmella satvctaecrucis, sp. n. 



Antennae greyish fuscous, paler beneath ; eye-caps dull ferru- 

 ginous, speckled with fuscous. Head dull ferruginous. Thorax 

 greyish fuscous. Foreiokigs pale cinereous, profusely speckled 

 with greyish fuscous, almost entirely obliterating the paler ground- 

 colour, which is confined to the bases of the rather coarse scales, 

 but shows more clearly where the scales become lengthened, as in 

 the cilia. Exp. al. 4'5-5 mm. Hindtoings and cilia very pale 

 greyish. Abdomen greyish fuscous. Legs pale cinereous. 



Type <S (99214) Mus. Wlsm. 



Hab. Tenerife: Santa Cruz, 15-17. I. 1907. Six specimens. 



I found this species at Santa Cruz, only among plants of 

 Lavandula abrotanoides, on which I noticed mines that appeared 

 to differ from those of Perittia lavandidae Wlsm. {a7ite, p. 971 

 no. 83) : they were more slender, and more toi-tuous, and probably 

 belonged to a Stigmella. 



143. (4378-1) Stigmella micromeriae, sp. n. 



Antennae grey ; eye-caps silvery white. Head yellowish. 

 Foreiomigs steely white, profusely sprinkled with coarse dark 

 grey, or fuscous, scales ; a straight silvery white transverse fascia, 

 at two-thirds from the base, is sometimes slightly interrupted by 

 a few of the darlc scales ; cilia steely whitish, with a slight 

 sprinkling at their base. Exp. al. 3-5-4 mm. Hindivings and 

 cilia pale steely grey. Abdomen grey. Legs greyish. 



Type $ (99220); S (99221) Mus. Wlsm. 



Hab. Tenerife: Guimar, 14. Ill - 12. lY, Micromeria varia, 

 25. II, excl. 1-9. lY. 1907. Twenty.two specimens. 



The larva feeds on Micromeria varia, and I think also on 

 Micromeria origanifolia, making small tortuous mines. It is 

 decidedly common.
