in the season than the writer, had produced an appearance like 

 a snow-storm around the Summit House, one day. Some of 

 the members reported finding indiyiduals of this Syrphus at- 

 tached to the sand by a fungoid growth, and appearing so life- 

 like as to induce caution in the attempt to capture them. One 

 member found a specimen attached to his blanket in the morn- 

 ing which had not been there the evening previous, showing 

 that the action of the fungus was quite rapid. The writer had 

 noticed a large gathering of individuals of this species on the 

 carriage-road, above the limit of large trees, at a time when a 

 brisk wind was blowing, and had found that sweeping his net 

 through the air near above them did not cause them to take 

 flight, but that it was necessary to take them up with the fin- 

 gers ; yet these individuals were fully able and ready to fly 

 when allowed to escape. A member who had been upon Mt. 

 Adams found the Coleopterous fauna of that mountain essen- 

 tially the same as that of Mt. Washington, although numerous 

 specimens of Hyperaspis were found there such as he had not 

 found elsewhere. 



Several members expressed the opinion that the distinction 

 between the subalpine and Canadian faunas was rather imagin- 

 ary. The prevalent opinion seemed to be that the wooded and 

 unwooded regions had distinguishing characteristics, but that 

 these regions merge into each other gradually. Carabus cham- 

 issonis has a wide range, being found in the Canadian as well 

 as in the two other regions. The specimens found at this time 

 were said to be wintered individuals, the new brood coming out 

 in August and September. Probably more specimens were 

 taken this year than in all previous years together. Many val- 

 ley forms of insects were found at the extreme summit of the 

 mountain ; the individuals at the summit visiting the extreme 

 peaks, even congregating upon a pile of stones, if no higher 

 point was near. None were found abundant even twenty or 

 thirty feet below the highest point. (July 8, 1874-^)
