change should continue, but many years must elapse before any broad 

 generalizations can be deduced from the mass of observations. Not 

 only must observers be more evenly spread over the land, but (as a 

 body) their special studies must also be less concentrated on one par- 

 ticular Order. 



The present short paper enumerates the species of " Nenroptera " 

 (mostly Trichoptera and Planipenma) observed by me during a 

 fortnight's visit to what may broadly be termed the lower portion of 

 the valley of the Axe, from July 28th to August 10th, 1902. The 

 weather was unpropitious, only an aggregate day of sunshine in the 

 14 ! ; not much rain, but nearly constantly cold, and if the tempera- 

 ture did rise occasionally, the result was supersaturation of the 

 atmosphere from former heavy rain. To be more precise in locali- 

 zation, the district explored embraced a radius of about five miles 

 from Seaton Junction Station, flat in the river valley, but undulating 

 (up to GOO feet) beyond. In 1879 the late Mr. Parfitt, of Exeter, 

 published the Ncuroptera of Devon in the l> Transactions of the 

 Devonshire Association Adv. of Science " for that year, but I find 

 therein no allusion to the district worked by me, though the informa- 

 tion for the Exe valley, further west, is tolerably full. I have thought 

 it advisable to include fin square brackets) certain species taken from 

 time to time at Seaton and neighbourhood by the Rev. A. E. Eaton, 

 some of which have been already recorded in this Magazine. My list 

 might, perhaps, have been somewhat longer, had not so much of my 

 time been devoted to one particular species (cf. ante, pp. 212, 213). 



TRICHOPTERA. 



TiiMNOPHiLiUjK : — Limnophilus marrnoratus, Ct., the Axe at Whitford ; L. 

 auricula, Ct., beaten out of conifers in the Royal Peer Park at Shute ; L. sparsus, 

 Ct., near Colyton. 



Sericostomatid^e : — Sericostoma pprso»nhim, Spence, along the Axe towards 

 Axminster, common ; and tributary to the Coly. Ooera pilosa, F., Whitford [Silo 

 pallipex, ¥., near Axmouth]. [Crunatcia irrorata, Ct., Axmouth and Seaton].

Hydp.optilidje : — Agraylea multipunctata, Ct., on the bridge at Whitford. 

 [Hydroplila Maclachlani, Klap., Axmouth and the Landslip. E.forcipata, Etn., 

 Shute. Oxyethirafaicata, Mort., Ottery and Kilmington]. One or two species were 

 common near Whitford, but only females were brought home. Mr. Morton has kindly 

 given me the benefit of his good eyes by examining the materials in this Family.

 Seaton] ; B. maurus, Ct., at a " dribble " on high land west of Shute [Seaton and
