necessary to cross the lake, here perhaps four miles wide. As 

 it was, we were able to visit any spot we chose. 



Owing, probably, to the sandy character of the soil at some 

 little distance from the lake, and to the immediate proximity of 

 the great plains of eastern Wasnington, the fauna presents a 

 rather mixed appearance. Many of the insects usually considered 

 peculiar to the great coniferous belt occur here side by side with 

 such genera as Eleodes and Coniontis, which, though not really 

 confined to the western plains, nevertheless constitute one of their 

 most striking features. 



Many of the Carabidae of the Coeur d'Alene district are of 

 great interest and rarity. Special mention might be made of the 

 Cychri, some species occurring here which are very seldom seen 

 in collections. Early in August and in late July Cychrus relidus, 

 regularis and rickseckeri are to be found along the lowlands bor- 

 dering the river and in the valley of the little creek which forms 

 the outlet of Trout Lake. The last-named species looks like a 

 feebly developed tuberculatus. On the further side of the lake 

 my friend, while hunting for snails, came across a single specimen 

 of C. merkelii, which was at that time still undescribed. Carabus 

 oregonensis was quite plentiful in the woods, under logs, not less 

 than sixty or eighty specimens being obtained. Calosoma mo- 

 niliatum and C cancellatum were seen somewhat sparingly. 

 Notiophilus hardyi was tolerably abundant in rubbish under logs. 

 Of Nebria we took specimens of sahlbergi and hudsonica, though 

 neither were abundant. 



Two curious Trogositidae were quite plentiful under bark or in 

 polyporoid fungi — namely Calitys scabra and Peltis pipings- 

 koeldii. The former looks exactly like a bit of rough, scaly- 

 brown bark, the inequalities of the upper surface reproducing 

 this appearance to a marvelous nicety. The Peltis is smoother, 

 but very much depressed, and is by no means readily detected, 

 unless in an exposed situation. Of the Nitidulidae notice should 

 appear of the curious Epuraa monogama, which lives, each 

 couple by itself, in fungi; Soronia gutiulata, of which only one 

 specimen was obtained, under bark, and Rhizophagus minutuSy 

 which was rather common in like places. 



Comparatively few captures of Elateridae were made, chiefly, 

 no doubt, on account of the lateness of the season. A few 

 Elater apicatus were found under bark, while a number of fine
