1(54; [December, 



on some of the species described by Zetterstedt as determined by Pastor Wallengren 

 from an examination of the types in fclie Museum at Lund. Since that time, he has 

 sent me a MS. list of his determinations of the species of the families PhryganeidcB 

 and Limnophilidce. The publication of a second edition of my ' Trichoptera Britan- 

 nica,' or a Supplement thereto, will be soon a matter of necessity, eight years haTing 

 elapsed since that work appeared ; but, as I have not yet decided which it is to be, 

 the notes are published here as a help to workers. The species known to inhabit 

 Britain are indicated by an asterisk. 



1. Phryganea pJialcBnoides. The Lapland specimens are Solostomis atrata, Q-melin 



the larger ones from Finland mentioned in the appended note are the true 

 H. phalcB/ioides, L. 



2. P. reticulata, = Neuronia lapponica, Hag., as already determined. 



3. P.grandis.* One specimen from Barrsele ^ P. ^/-aBc^is, L. ; seven specimens from 



Lycksele = P. striata, L. These two species were universally confounded until 

 Hagen, in 1851, pointed out the striking differences. 



4. P. varia,* = P. varia, F. ; but Wallengren states that the var. b. = P. striata. 



5. P. grisea,* = Limnopihilus gi'isens, L. 



6. P. rhombica,* = L. rhombicus, L. 



7. P. borealis.* I had long suspected that the insect known as Limnopliilns bbrealis 



was not Zetterstedt's species, and it appeared to me that his description agreed 

 far better with L. pavidus, Hagen. Wallengren states that Zetterstedt's types 

 are pavidus. Hence a now name is necessary for our so-called borealis, and I 

 propose that of xanthodes. I am not yet perfectly clear about the borealis of 

 Kolenati and Brauer, though that of the latter is possibly xanthodes, and the 

 former I think is Zetterstedt's species. The true borealis fpavidiisj is a truly 

 northern species ; I have recently seen another British specimen, taken by Mr. 

 Traill at Strathnaver in August of the present year. 



8. P. afomaria,* = L. marmoratus, Curtio. 



9. P. signifer,* = L. elegans, Curtis, as already determined. 



10. P. lineola,* = OrammotatiUus nitidus, Miiller. 



11. P. irrorata,* = G. atomarius, F. 



12. P. interrogationis. Wallengren states that the $ type is perhaps only G. ato- 

 marius, but he is, however, inclined to consider it a good species, which the 

 examination of a c7 can alone determine. 



13. P. vitrata,* = LimnopMhis lunatus, Curtis. 



14. P. notata,* = L. ajffinis, Curtis. 



15. P. fenestrata,* = L. auricula, Curtis. 



16. P. vittata,* = L. vittatus, F. 



17- P. femorata,=^ L. femorata, Zett. At present unknown to mo. 



18. P. trimaculata,^ L. trimaculatus, Zctt. 



19. P. fuscinervis, = L. fuscinervis, Zett. 



20. P. subpunctulata, perhaps a pale L. extricaius, McLach., but Wallengren 



expresses himself uncertain about it. 



21. P. nigriceps,* = L. striola, Kolenati ; the former name is the older. 



22. P. Imvis is an Anabolia of the gi'oup of A. nervosa ; hence this has been wrongly 

 referred to Ayrypnia Vagetana.
