290 ENTOMOLOGICAL NEWS. [November, 



species. Here were found two or three specimens of Scotodes 

 americanum Horn, a pair of Tetropium cinnamopterum, Campy - 

 lus denticornis, and the dainty little Longicorn, Pogonocherus 

 penicellatus; also flies, bees and ants. Even Medford's shaggy 

 coat proved remunerative, and I took off it, as the grand old dog 

 lay in the sunshine one warm noon, a fine specimen of Chryso- 

 bothris trinervia which flew and lighted there as I looked on. 

 Several specimens of this Buprestid were taken on the summit. 

 Dr. Packard, in his " Forest Insects," speaks of it as occurring 

 in the pine forests of Colorado, and it is probable that it bores in 

 pine trees, as do so many of its congeners. Some, perhaps 

 many, of these wood-boring beetles found on the summit are 

 brought up in the wood piled near the base for fuel. I have 

 taken Upis ceramboides , Iphthimus opacus and Scotobates calca- 

 ratus on these logs in former years and have seen ants running 

 in and out of holes and tunnels here. I searched faithfully for 

 the larvae or pupae of the Agrotidee peculiar to this fauna, but 

 found but two of the latter under moss near rocks. These both 

 were covered with a mould or fungoid growth and did not de- 

 velop. One larva of C. semidea was taken on sedge (Carex vitl- 

 garis var. hyperborea). It was the green form and full grown. 

 It fed well in confinement on its natiye food-plant while still on 

 the mountain. When I brought it down to Franconia I gave it 

 various species of Carex growing near, and it ate indiscriminately 

 of each and all, thus showing a deplorable ignorance of botany, 

 and one day it disgraced itself still more deeply by eating vora- 

 ciously of blue grass (Poa pratensis} apparently quite unable to 

 distinguish between Cyperaceae and Graminaceae. But after 

 about three weeks of this varied fare it fell into a stupor and has 

 slept ever since, alive but motionless, in its hybernation I sup- 

 pose. I came down the mountain on the i4th, after a week's 

 stay. On August 22d I again went up, hoping to find Argynnis 

 montinus. I had been waiting at the Crawford House nearly a 

 week for favorable weather. It had been cold and foggy, with 

 much rain and wind all that time. The 22d was cold and bright, 

 with a fair prospect of settled good weather. I had planned for 

 only two days on the mountain this time. The forenoon of the 

 23d was bright and pleasant, though not very warm, and I did 

 some fair collecting. Six specimens of Argynnis montinus were 

 taken, but the week of storm had somewhat dimmed their beauty,
