978 LORD WALSINGHAM ON THE [Nov. 26, 



Type 2 (99090); rf (99091) Mus. Wlsm. 



Hob. TENERIFE: Villa Orotava, 6. V, 1907; Puerto Orotava, 

 Genista stenopetala, 8. Y, excl. 13-16. Y. 1907; La Laguna, 

 Spartium junceum, 21. Y, excl. 23. Y - 6. YI. 1907. Seventy- 

 eight specimens. 



This is apparently allied to cytisellus Rbl., and, like it, is also 

 very variable in the intensity of its markings, which in some 

 specimens are more or less evanescent, but, whereas in cyti- 

 sellus the white so strongly predominates as to overrun the wing 

 and leave golden markings, in juncei the golden ground predomi- 

 nates, leaving white markings. I have a long series of bred 

 specimens of both species, and can never be at a loss to distinguish 

 them. 



I first found juncei in the garden behind the Hotel Yittoria, 

 Villa Orotava, flying freely about Genista stenopetala, and after- 

 wards bred it from leaves of the same, gathered at Puerto Orotava ; 

 but it was even more abundant on Spartium junceum, by the side 

 of the road from La Laguna to Tegeste, where, in one spot only, 

 for about 100 yards, almost every leaf of these plants was affected 

 by the larvae. The species is described from specimens bred from 

 Spartium junceum. 



95. (4207* 1) PHYLLONORYCTER FOLIOLOSI, sp. n. 

 (Plate LIII. fig. 8.) 



Antennae white, with blackish annulations. Palpi white. 

 Head and Thorax pale golden brown. Foreivings pale golden 

 brown, with four costal and three, or four, more obscure, white 

 dorsal streaks ; the first two pairs opposite, and frequently 

 appearing as two fasciae by meeting each other, a slender whitish 

 streak sometimes connecting them along the middle ; between the 

 white streaklets, as well as towards the base, the wing is plentifully 

 bestrewn with minute black scale-points ; cilia mixed golden and 

 whitish, becoming greyish along the dorsum. Exp. al. 4-5 '5 mm. 

 HindwingsKJid cilia pale grey. Abdomen grey, anal tuft ochreous. 

 Legs yellowish white. 



Type J (99092) ; $ (99093) Mus. Wlsm. 



Rob. TENERIPE: Guimar, 25.11 - 6. III. 1907, Adenocarpus 

 foliolosus, 26. II, excl. 1-10. III. 1907 (Wlsni.)- La Laguna, 

 25. III. 1904 (Eaton}, 23. V - 9. VI. 1907, Genista canariensis, 

 18. V, excl. 5-15. VI. 1907 (Wlsm.). Fifty-three specimens. 



The larva feeds in the tiny leaflets of Adenocarpus foliolosus, 

 at Guimar, at about 2000 ft. above sea-level, sometimes giving 

 to the branches a whitened appearance, through the bleaching of 

 innumerable leaves ; I found the same species later, at La Laguna, 

 on Genista canariensis, where Mr. Eaton had taken it in March 

 1904. 



The species is allied to parvifoliellus Rgt., but differs in the 

 more numerous costal streaks.
