But he then proceeds—" Quite fresh female specimens, 

 which Professor Frey took in the Engadine, at a height 

 of 5200 feet, are distinguished by their wings being 'much 

 narrower, and the anterior are milh ivliite, with coarse 

 black dots, which are placed in four irregular longi- 

 tudinal rows, the oblique fascia in the middle is blacker, 

 more defined, and is prolonged as a hroivn shade in the apex 

 of the wing." Here all the characters italicised point to 

 a new species, and strangely enough, when speaking of 

 the palpi, Herrich-Schiiffer remarks, " in the female the 

 third joint of the palpi is rather club-shaped, as in the 

 genus Zellcria," and was thus on the very point of dis- 

 covering that the two insects were generically distinct. 



Inl856Herrich-Schufler figured in his Neue Schmetter- 

 linge. Heft I. fig. 45 — as " a very distinctly marked female 

 of Suummerdamia alpicella from the Alps'^ — the new 

 species which I have no hesitation in referring to the 

 genus Zelleria. This figure is a remarkably good one, 

 except that two dark streaks are represented near the 

 base along the fold and below the subcostal nervure, and 

 my specimens do not show any such streaks, only a slight 

 cloud at the base of the costa. 



When I first saw this Zelleria, I believed it identical 

 with the Zelleria fasciapennella, Logan, and it would 

 appear that I so determined a specimen for Professor 

 Frey. Frey's fasciapenneUa is, however, judging from 

 his description of the markings in the apical cilia, clearly 

 identical with the insect figured by Herrich-Schiiffer in 

 his Neue Schmetterlinge. 



On comparing bred specimens of this Alpine Zelleria, 

 with Scotch specimens of Z.fasciapejinella, the differences 

 between the two are sufficiently obvious. The Alpine 

 Zelleria is a smaller, neater, whiter insect, the medial 

 fascia starts more obliquely from the inner margin, and 

 does not reach the subcostal nervure, so that no complete 

 fascia (as in the Scotch insect) is formed, and the two 

 dark lines round the apex in the cilia are sharply and 

 distinctly marked, whereas in the Scotch Z. fasciapen- 

 nclJa we see scarcely a trace of any such markings; besides 

 this, the Alpine species has the posterior wings paler and 

 more pointed. 



At the end of May, 1865, Herr Ernst Hofmann disco- 

 vered on the Kaiserberg, near Oberaudorf, a larva feeding 

 in the heart of Saxifraga aizoon, of which he kindly sent 

 me two, one of which was figured by Miss Thomson. 

 From the larva3 he collected in 1865 only a single crip-
