STRAY NOTES OX SWISS TRICHOPTERA. 17 



Hag., one specimen; Tinodes sp. Agapetus cornatuK, Pict. 

 Also Sisyra fuscata, Fab., Chrysopa l-punctata^ Wesm., 

 Ephemera glaucops, Pict., and sundry undetermined small 

 PerlicIcB. 



At Maria, on the 24th July, thirteen specimens, and at 

 Andermatt, 10th August, one specimen, of a JPanorpa, 

 which is certainly that figured as jP. vulgaris in Imhoff and 

 Labram's *^ Insekten der Schweiz," but which I cannot 

 separate by any structural chai'acters fiom P. communis, 

 although its small size and very shaiply-marked wings give 

 it a difFei-ent appearance. M. De Selys-Longchamps finds 

 the same form in Belgium with communis, yet appearing to 

 keep itself distinct. If only a variety, it is certainly a well- 

 marked one. 



I believe I have now given a rhume of my friend's doings 

 in Switzerland, so far as they concern me. He brought 

 home over 300 individuals, comprising the before-named 

 species; and it must be remembered that these were only 

 the casual captures of an entomologist who had his own 

 special pets to look after, and who is probably not acquainted 

 with all the devices whereby caddis-flies may be dislodged 

 from their retreats. For instance, at the Lago del Croce in 

 the Bernina Pass, Mr. Stainton searched in vain for a 

 single Ti'ichopterous insect. Professor Zeller, however, 

 assures me that had he been there he would not have re- 

 turned empty-handed. 



Son3e years since, I heard that a Monograph of Swiss 

 Trichoptera was in preparation by M. E. Pictet, son of the 

 author of the ^'Recherches.'' Need I say how eagerly such 

 a work has been looked for by me. But the realization of 

 the project would now seem as far distant as ever. 



1871.
