26 [January, 



Perhaps, on the whole, Saeterstoen is more an ideal locality for 

 Lepidoptera than for Neuropiera and Trichoptera. By going further 

 afield a series of lakes might have been included in our area, but it 

 ■was inconvenient to visit them. As it was, we worked only one small 

 lake ; for the rest we had the great river Glommen and its backwaters, 

 one or two small brooks, and several ponds and marshes of diverse 

 character. Considering the swampy nature of the district, there was 

 not a superabundance of open standing water. 



Some of the ponds in the woods were quite charming, being filled 

 with Calla palusfris, whose beautiful spathes were fully open. Over 

 the water flitted hosts of two red -bodied species of Leucorrhinia and 

 other dragon-flies. One day when working at one of these forest 

 ponds, two eagles circling overhead helped to confirm the delightful 

 feeling that although so near the accessories of civilization, we were 

 where wild Nature still holds a place. 



The Corduline Dragon-flies were a feature in the insect life of 

 Saeterstoen ; examples very constantly being seen flying along the 

 railway, or high over the trees in the wood, usually difficult to secure 

 in these circumstances. These, I take it, were either females, or males 

 recently emerged. The males of G. cenea were abundant about the 

 backwaters and the lake, while the males of 8. metallica were frequent 

 at other standing waters. *S^. arctica I could not find at home, a stray 

 female being the only one seen. 



Agrion was well represented in number, but chiefly A. liastulatmn. 

 Another small species not recognised at the time proves to be an in- 

 teresting northern species, A. concinnum. 



The conditions of Trichopterous life in the Glommen puzzled me 

 a good deal. At British rivers in the month of June the burst of life 

 is enormous ; on the Glommen for the first few days I could find 

 absolutely no TricJioptera, nothing but a Chloroperla in numbers and a 

 species of the Epliemeridae. Later Trichoptera did appear, but not in 

 large numbers. I can only conclude that the Glommen is a cold, late 

 river. On the Clyde Limnophilus fuscicornis occurs at the end of 

 May, while the same species seemed to be just appearing on the 

 Glommen towards the end of June. 



Leaving Saeterstoen on June 2Sth we proceeded to the Dovre- 

 fjeld by way of Lake Mjosen and the Gudbraudsdal. Between 

 Lillestrom and Eidsvold we saw from the railway plenty of Oalopteryx 

 virgo, and between Lillehammer and Otta, the present terminus of the 

 railway, what appeared to be Pariuissius Apollo in abundance. Neither 

 of these insects was seen elsewhere. At Braendhaugen Lycoena
