The species described as Swedish are Platyptilus ochrodactylus, 

 P. Zetterstedtii, P. nemoralis, P. gonodactylus, and P. tessaradactylus ; 

 this latter species, which is known on the continent as P. Fischeri, 

 Zell., being supposed by our author to be the tessaradactylus of Linne. 

 It is probable that under ochrodactylus the two species dichrodactylus 

 and Bertrami are both included, since the monograph bears date 1859, 

 and the larva is recorded as unknown. This would make six Swedish 

 species of this group. "We have only five in Grreat Britain, viz., P. 

 dichrodactylus, P. Bertrami, P. isodactylus, P. Zetterstedtii, and P. 

 gonodactylus. Of these, P. isodactylus is apparently unknown in 

 Sweden, and, on the other hand, P. nemoralis and P. Fisclieri are not 

 met with in Britain. The larva? of this group are feeders in the 

 stems of composite plants. P. Zetterstedtii is one of the rarest of our 

 native plumes, and seems, as far as we at present know, to be con- 

 fined to the south-western sea-board. Owing to the kindness of Mr. 

 Doubleday, I have at present two fine specimens lent me for examina- 

 tion, taken by Mr. Bond on the Cornish coast ; and Lynmouth is given 

 as another locality. The Isle of Man and Ireland should be examined 

 for this species. The larva, according to Wallengren, feeds on Senecio 

 nemorensis. It must in England, of course, choose some other compo- 

 site, — probably also a Senecio. 



3. Ambltptilus (Hiibn.). 



Antennae of both sexes with very short cilia. The forehead ornamented with a 

 short pyramid of scales. Palpi longer than the head, thick, laterally compressed, 

 ascending, with the last joint short, slender, and pointed. Legs slender, long, the 

 tibiae only in the least degree thickened towards the apex. First pair of spines in 

 the posterior tibiae nearly equal, longer than the second pair. The anterior wings 

 furnished with a tooth of scales on their inner margin, not cleft to the third part 

 of their length. The segments broad, the posterior segment almost hatchet-shaped, 

 the posterior angle of the segments well marked. The segments of the inferior 

 wings slender, the third segment with the anal angle sufficiently distinct, nearer 

 the apex, furnished with a tuft of scales. The anterior wings flat, covering the 

 posterior when at rest. 



This group contains the same species in Sweden as with us, 

 namely, acanthodactylus and cosmodactylus. Our author regards them 

 as varieties only, a conclusion with which British entomologists will 

 hardly agree. 



4. Oxtptilus (Zell.). 



Antennas of both sexes with very short cilia. The forehead obtuse, wanting the 

 tuft or cone entirely.* The palpi longer than the head, thick, laterally compressed, 



* Except in Bohemani?—1X. C. K. J.
