costal streak ; at the extreme apex is a bright golden metallic spot ; these golden 

 markings are all distinctly and brilliantly iridesc-cnt, and the white streaks on the 

 costa are very pure, and with a silvery lustre ; cilia greyish-fuscous. 



Hind-wings, grey, with greyish-fuscous cilia. 



Abdomen, grey. 



Legs, brown, tarsal joints spotted with white. Exp. al., 6 — 7 mm. 



Larva, mining leaves of Rosmarinus officinalis, March and April. 



Imago, June 2l8t — July 7th.

Type, S ? > Mus., Wlsm. 

 The only differences I can detect between this species and Qra- 

 howiella, Stgr., are as follows : the white on the costal margin is more 

 purely white and silvery, the golden scaling is more distinctly iridescent, 

 having lilac- and rosy-purple reflections, which do not exist to the 

 same extent in Grabowiella, the hind-wings are decidedly grey, not 

 brown, the antennae having a different pattern, the four spots nearest 

 the apex being evenly divided, and not separated from the more thickly 

 spotted part of the stem by any broad brown band, whereas in 

 Graboiviella the basal half is thickly spotted with white, this is followed 

 by a broad brown band, and beyond it are five evenly divided white 

 spots ; the spotting of the hind tarsal joints is also somewhat different, 

 in this species there are four distinct white spots, in Graboiviella only 

 three, the fourth being the foot itself. 



The larva of this insect was discovered by Mr. Staintou in 1866, 

 but he did not succeed in rearing the imago. Its life-history, which 

 is recorded in " The Tineina of Southern Europe," p. 215, is as 

 follows : — 



" A yellowish larva, mining the leaves of rosemary {Rosmarinus officinalis) ; 

 the mined leaves become yellowish-brown, and rather inflated ; some excrement is 

 protruded through a hole on the under-side of the leaf, generally at the end of the 

 mine nearest the foot-stalk. 



The larva I have thus described : — 



Length, 2 lines ; yellowish, the incisions between the segments rather paler ; 

 the head dark brown ; the second segment with a brown plate above ; the anal 

 segment with a small grey plate ; all the legs (16) pale yellowish. The larva is 

 rather active. 



I met with these on the 27th March, the day before I left Mentone, on the 

 rocks above Pont St. Louis, on the Italian side. 



I did not succeed in rearing anything from them." 



The larva, with which I have been well acquainted for several 

 years, differs from that of the closely allied Graboiviella in its habit 

 of pupating within the mined leaf, never forming a case of excrement, 

 but it moves from one leaf to another when feediu-i;.
