found at Tonset,* and supposed by Mr. Baker to be a new species for 

 Norway, I must call attention to the fact that Boheman first detected 

 this species on Dovrefjeld, 1832. In 1887 I have myself taken it 

 both on Dovrefjeld and in G-udbrandsdal, and, in 1884, in Snaasen, 

 northern Throndhjem, Amt. 



The other species mentioned are all more or less common in 

 several districts of Norway, though some of the localities are new.

Notes on Agrypnia Pagetana and other Trichoptera. — On the 7th instant, a very 

 hot and sultry day, I met with Agrypnia Pagetana in great numbers at Hogganfield 

 Loch, near Grlasgow (about 250 feet above sea level). This loch is almost over- 

 run with Anacharis canadensis, and the insects were crawling over the carpet 

 which this plant forms, or resting on horse-tails after short nights. In about an 

 hour (between 1 and 2 p.m.) .almost without moving from one spot, I easily captured 

 twenty specimens. Judging from their conduct, and the condition of the examples 

 taken, I think the insects were just emerging. If I am right, then the species under 

 notice differs in this respect from some of the Phryganeidce ; for example, Phryganea 

 striata, the imagos of which I have often seen developed about sunset. While most 

 of the members of this family have a nocturnal flight, I think P. obsoleta, at least, 

 flies voluntarily in the hot sunshine about the margins of its breeding places. 

 Whether Agrypnia Pagetana normally possesses the latter habit, I am not yet quite 

 certain, but most probably it does. The only other species noticed at Hogganfield 

 were also Phryganeidce, viz. : Phryganea striata and P. obsoleta. 



In the Carluke district, Trichoptera are appearing early, and in force. Species 

 rarely observed before the second week in June under ordinary circumstances, have 

 been out for some time. Of Stenophylax vibex, always a rare insect, I have already 

 seen more specimens this season than in several previous years' collecting. A fine $ 

 came the other night to a lighted window ; another $ , almost intact, was found in a 

 spider's web, and two other caddis-flies found in the same position were pretty 

 certainly the same species, but too mutilated for pcsitive identification. — Kenneth

Ravages of Cecidomyia (Diplosis) pyrivora, Riley. — There were notices of this 

 insect last year (Ent. Mo. Mag., xxiv, pp. 273, 274, and Riley's " Report of the 

 American Entomologist," for 1883, pp. 283 — 289). The pears I now send are 

 beginning to shrink, from the drought and heat in part, and in part because their 

 vitality is destroyed by the larvae, and in a few days they will turn black. The larvse 

 leave the pears and fall to the ground ; they have great saltatory powers if placed 

 on a plate. This year I find no Marie Louise pears affected, last year they were the
