their wings and hang quite still upon the shrubs while a cold 

 storm cloud is passing over, only to awake to active flight al- 

 most the instant that the sun comes out again. 



The dirty, smoky city covers a great deal of ground and it 

 is something of a walk from the ''up town " hotels into the 

 wooded hills which rise on every hand. The large timber, if 

 there ever was much of it, is now mostly gone and the re- 

 maining trees are chiefly so dwarfed or undersized as to be of 

 no use for commercial purposes. To this they owe their ex- 

 istence and as they still support some insects let us hope that 

 they may long remain undisturbed. Many of the large ra- 

 ■\^nes and gulches have been ruined entomologically by exten- 

 sive mining operations but a. few spots were found which 

 yielded tolerably well. The stonj' porous soil of most of the 

 hillsides holds but very little water and supports a fauna 

 which is in strong contrast to thatof the marshy valley region. 



We saw no living CieindeUdce during our stay, but some dead 

 C. cinctipennis served to show that the species extends up the 

 valley from Buena Vista, where it was seen rather abun- 

 dantly. On the higher slopes of Moose Mountain, which lies 

 near enough to Leadyille to make the summit, though far 

 above timber line, tolerably easy of access on foot, we took 

 CarabuH tcedatus, of the form which I have always considered 

 as representing oregonensis and have distributed as such. It 

 was scarcely common, but we managed to get several under 

 stones and logs in the valley of a little stream which heads on 

 the mountain. The banks of this stream were lined with 

 stones under which we found a few ^ebria ohliqua and N tri- 

 faria, Patrobus aferrimus and some Staphylinidse, while Bembi- 

 dium incertum, B. grapii and Treclmn cTrnlybeus were secured 

 with them but in more abundance. All of these bank loving 

 Carabidfe were found in the wettest, coldest spots, often in the 

 spray from a small cataract and their capture was attended 

 with a good deal of bodily discomfort, owing to the rains and 

 the very low temperature of the water in these mountain 

 streams which are mainly fed from snow fields lying higher 

 up. 



Following the ravine we finally emerged from the timber 

 and found ourselves on the bald, rocky head of the mountain, 

 where no trees grow, for after leaving the fringe of gnarled,
