NOTES OX BRITISH TRICHOPTERA. 147 



coverino; of this kind, and lie free within their cases. The 

 larvae of some species of the genus Tinodes consti'uct rather 

 serpentine covered ways on the surfaces of large stones. 



In arranging the foregoing notes, I have drawn largely for 

 information on Pictet's monograph of the species inhabiting 

 the environs of Geneva. I have myself been singularly un- 

 fortunate in my attempts to rear these insects, though 1 have 

 had the larvae of almost all the genera. 



With regard to the additions to our list that I have to 

 record this year, I can speak only of three with any degree 

 of certainty, viz. — 



Limnejjhilus nohlUs, Kolenati. 

 Anaholia ccenosa^ Curtis. 

 Hydropsyche opthabnica, Rambur. 



There are also a few corrections to make in the S3monymy, 

 and the new species are arranged in their proper order in the 

 notes which follow. 



Limnephilus horealis, Zett. Mr. Birchall kindly gave 

 me a specimen of this insect that he took at Killarney, an 

 entirely new locality. 



Limnephilus nohilis, l\.o\enaU, (Chcetotaidius nohilis, Kol. 

 Gen. et Spec. Trichop. pt. 1, p. 433). This new species to 

 our lists is intermediate between L. flavicornis, Fab., and 

 L, stigma^ Curtis. In the colourless ground of the anterior 

 wings it resembles the former, but it possesses a very distinct 

 obliquely placed fuscous pterostigma, internally gradually 

 narrowing to a point; the fenestrated spot is rather broad but 

 very indistinct ; the apex is clouded with dark grey, with 

 transparent irrorated spots ; the anterior wings are narrower 

 than in either Jlavicomis or stigma. In the form of the 

 appendices it differs greatly from any of our previously 

 recorded species. In the male the upper margin of the
