Insects. 



List of PhryganidtB taken in 1862. By Percy C. Wormald, Esq. 



The following is a list of the Trichoptera which I have captured 

 (with few exceptions) during the present year. 1 did not meet with 

 a single species till the 1st of May, when I took two, Limnephilus 

 costalis and L. fumigatus, though there is one species, Brachycentrus 

 subnubilus, Curt., which appears in April, and has been taken in 

 Devon by Mr. Parfitt. It is said to occur near London, but my search 

 for it was unsuccessful. During a short visit to North Wales I cap- 

 tured a Rhyacophila new to Science, which has been named R. ob- 

 literata by Mr. M'Lachlan. 



Phryganea grandis, L. Common on palings at West End, Hamp- 

 stead, end of May and beginning of June. 



P. striata, L. One specimen near Hampstead, May 18. 



Colpotaulius incisus, Curt. Common at Hammersmith Marshes, 

 June 28. 



Limnephilus pellucidus, Oliv. Hampstead, Hendon and Ruislip 

 (Middlesex), West Wickham and Epping Forest ; appears throughout 

 the summer; first seen May 19, last seen September 13. 



L. vitratus, De G. Kilburn, Kew, Ruislip and Bala Lake (N. Wales), 

 middle of June to October. 



L. rhombicus, L. Canal near Willesden (Middlesex), from middle 

 of June to beginning of September. 



L. marmoratus, Curt. Kew and Ruislip, August ; common at the 

 former locality. 



L. flavicornis, Fab. One specimen near Hampstead, June 7 ; com- 

 mon at Ruislip in August and September. 



L. stigma, Curt. One specimen, June 26, at Ruislip ; common in 

 August and September at the same place. 



L. bipunctatus, Curt. 9 One specimen near Hendon (Middlesex), 

 June 22. This appears to be rather a scarce species. 



L. auricula, Curt. Near Hampstead, Coombe Wood, Epping Fo- 

 rest and Ruislip ; also at Llangollen and Bala (North Wales) ; end of 

 May to end of August. 



L. costalis, Step. A very common species, at the commencement of 

 the season, in most woods, &c. ; is out from the beginning of May to 

 September. 



L. vittatus, Fab. Ruislip and Epping Forest, end of June to end 

 of September ; common. 



L. centralis. Hampstead and Epping Forest, June and August; 

 not common.
