it is, however, easily distinguished by its larger and wider shape, its differently 

 coloured head, and thorax widely margined with yellow. — W. W. Fowler, Lincoln :

Two additions to the Dragon-flies of Switzerland. — In August of this year I 

 spent ten days in the Engadine, making Pontresina my head-quarters. Being 

 specially in quest of Trichoptera my attention was principally directed to them, and 

 I hope hereafter to publish a list of the species captured, with notes on the 

 excursions, &c. In the course of my wanderings I came upon the little " Statzer-See " 

 (scarcely more than a large pond) between Pontresina and St. Moritz by the wood- 

 path over the side of the mountain, and lying at an elevation of about 6200 feet. 

 It is fed by springs and very small streams, is uncontaminated by snow or glacier 

 Water, and it has a wide fringe of very boggy ground (as I found to my cost). So 

 it is essentially fitted for alpine Dragon-flies and other Neuroptera. I soon found it 

 was the haunt of species of the genus Cordulia, and on three days from August 12th 

 to 16th, 13 examples of this genus were secured, which proved to consist of 9 $ of 

 C. melallica, 1 $ of C. alpestris, and 2 <? , 1 ? of C. arctica, the latter being new 

 to the Swiss Fauna. Large JEschnce were not uncommon, but it was almost 

 impossible to capture them. Only three individuals were taken, viz : — Mi. juncea 

 S ? and JE. borealis $ , the latter also new to Switzerland. In June, 1865, I had 

 taken C. arctica and JE. borealis at Rannoch in Scotland, thus it was like the 

 renewal of old acquaintanceship ; but the surroundings were very different. The 

 other Dragon-flies were not important, and the season was already advanced. The 

 larger Lake of St. Moritz, although not a mile away, and into which the " Statzer- 

 e " discharges, did not furnish a single Dragon-fly, a fact only to be explained by 

 the very different physical conditions of the two lakes. — Pv. McLachlan, Lewisham : 

 September 30th, 1880. 



Chry sop a pallida in Switzerland. — Towards the end of August, I was a few 

 days at Thusis, in the vicinity of the celebrated gorge known as the Via Mala. Five 

 examples of the fine large C. pallida were secured by beating spruce firs, a species 

 altogether new to^this part of Europe. Others were seen, and it is probably rather 

 common ; but a series of small storms rendered beating chiefly productive of 

 drenchings. — Id. 



Extreme abundance of Ccecilius pedicularius. — "Will you kindly tell me the 

 name of the enclosed insects ? 



I take the liberty of applying to you because I suppose them to be Psocidce. 

 I know next to nothing of this family, and have not time to work it up, but I like 

 to obtain an insight into any branch of Natural History that forces itself upon me. 

 And this these little flies have done, for they abounded in my corn-fields and were 

 a source of great annoyance to the harvesters by settling and crawling upon their 

 arms and faces. Subsequently, on hot days, they have been on the wing in incredible 

 numbers. 



Am I right in supposing them to feed on fungoid growths ?, if so, the mildew 

 would account for their presence on the corn. — Thos. H. Haet, Eingsnorth, 

 • Ashford, Kent : October 9th, 1880.
