THE CANADIAN' ENTOMOLOGIST. 229 



beautiful mottled Anihicus ; not at all rare, and a few other things, Mala- 

 chiidie and Curculionidae, etc.; among them a beautiful Otiorhynchid, 

 with cream-coloured elytra, showing metallic copper-red colours beneath. 

 On cedars below the hotel there was a Helops, some Cistelidce, Elateridce, 

 and one specimen of a very large Longicorn of a genus allied to 

 Anthophylax. Under loose stones on the dry hillsides I found good 

 Carabidae, Harpalus, Ainara, PterosticJms, and a Cymindis, quite com- 

 mon. Continuing down the mountain side about i,ooo feet I finally 

 reached the Gardiner River, which is a cool, rapid, mountain stream, 

 bordered with tall willows, larch, birch, aspen, wild rose, cherry, etc. 

 Here J find covered beaches with an abundance of Nebrias of several 

 species. A large one, with yellow legs, may be the species found about 

 the geysers. The black species are either very variable, or there are 

 several species among them. I think the smallest, which has a tendency 

 in some localities to become brown in colour, is not a Nebria, but belongs, 

 perhaps, to Pelophila. There is also a very elongate black form which 

 resembles a Patrobiis, but is of very large size. Here I found a very 

 neat Elmis, quite different from those known to me. It is moderately 

 large, uniform dark-bronze in colour, and of very short, thick, form. It 

 lives very differently from any Elmis I ever saw. It is U7ider small stones 

 close to the shore, and can only be found by disturbing the gravel with 

 the hand, whereupon the beetles are upset and float about in the water, 

 and seize upon the rootlets of willows that grow among the stones. This 

 same Elmid I have found since in a little trickling stream which came 

 down the steep bank of the Yellowstone River near this place. This 

 little stream was as cold as ice, and densely shade'd with nettles and a very 

 tall umbelliferous plant. The Gardiner River was the first stream I had 

 found that is a natural mountain torrent. All the streams in the western 

 part of the Park are vexed with devils of one sort or another in the 

 shape of hot water, sulphur and steam, and are full of queer, slimy algfe, 

 deposits of lime, etc. The Yellowstone River which flows near me here 

 is also partly sulphur water, but still it is full of trout, and its shores pro- 

 duce all the species of Nebria, Pelophila and Patrobus that I have men- 

 tioned. I find also in shady places, where moss grows under willows by 

 the borders of the streams and in debris, a few Bledius and Micrcedus, 

 with one or two other Omalini. Deep in a pile of debris on the shore of 

 the Yellowstone River near here I found also Diaiwus.
