1904. J 53 



specimens taken by Roper-Curzon and Kiw^ having been considered 

 worthy of a varietal name. It belongs to a group ol: more or less 

 allied species (belonging to more than one genus) which are purely 

 nocturnal fliers, and whicli seem to be veritable Trofflodi/tes in their 

 daylight habits of concealment. As far as my experience goes, they 

 hardly ever fall to the beating stick or get into the sweeping net in 

 the daytime. 



The following were the species taken : — 

 TRICHOPTERA. 



Phryganea varia, F. — One ? ; the species was over. 



Olyphotmliufi pellucidiis, Retz. — At Coniston, but much commoner at Esthwaite ; 

 one $ a very beautiful dark variety. 



Limnophilus marmoratus, Curt. — Very common. L. lunatua, Curt. — Most 

 abundant. L. vitfatux, F. — No doubt common, but only one or two kept. 

 L. auricula, Curt. — Here and there. L. sparsus, Curt. — Common. 



Anabolia nervosa, Curt. — In multitudes, differing much in size at different 

 points of the lake. 



Stenophylax stellatus. Curt.— Frequent ; taken ratlier commonly hiding in 

 the crevices of a wooden house at the Ferry near Bowness, Windermere. These 

 lake examples are smaller than the average specimens from large rivers ; they are 

 also paler in colour than most of the other recent examples before me, this paler 

 coloration being a local characteristic, while the small size seems to be connected 

 with the lake habitat, similar small examples having been found by uie at Loch 

 Rannoch earlier in the summer. The Rannoeh examples, however, are very dark. 

 >S. Jatipennis, Curt. — Occasionally at smaller streams. 



Mesophylax impunctatus, McL.— Three ? were taken by beating and sweeping 

 at night. They were all from a comparatively limited stretch of the lake margin at 

 Coniston, near a point at which a beck enters the lake. The true character of the 

 shore at this place I am unable to describe, as it was continuously flooded during 

 the whole time of our stay, and it is impossible to say whether any little springs, 

 such as those which Micropterna (and probably Mesophylax) delights in, occur 

 there. 



Halesus radiatus, Curt. — Rather common. 



Drusus annulatus, Steph. — Very common. 



ISilo palUpes, F. — Only a few seen. 



Crunwcia irrorata, Curt. — Frequent at suitable places near Coniston. 



Lepidostoma hirtum, F.— One or two stragglers. 



Berxa mauriis, Curt. — One female. 



Leptocerusfulvus, Ramb.— Seen only at Brothers' Water ; the species was over. 

 L. cinereus. Curt.— Coniston Lake. L. dissimilis, Steph.— Fresh specimens occurred 

 at Coniston Lake, but were not very numerous. 



Mystacides azurea, L. — Very abundant. 



Oecelis lacustris, Pict. — Nearly over. O. testacea, Curt.— The ? was still 

 pretty common at Coniston. 



^e^odesan/ert^i/JMwc^eWa, McL. — This charming little insect was still in evidence 

 at different points of Coniston Lake, but nearly all were ? .
