idalia, Colias philodice, Pieris rapcB, Chrys. amerkanus, Arg. myriiia. 

 and several common species of the Hesperidce. 



Lim. arthe??iis was very common, frequenting tlie beds of brooks, 

 open lanes, and sunny spots in the woods. On damp sandy spots they 

 were often gathered in bunches of fifteen to thirty, ami especially about 

 bits of decaying matter and the dung of wild animals. Other varieties of 

 this species were not seen. 



At the summit of Mt. Kearsage, I tdok Li?n. arthemis, Mel. Har- 

 risii, Van. antiopa. Pap. tiirnus, &c. In fact the altitude, 3200 feet, does 

 not interfere with the habits of valley butterflies. 



I reached the summit of Mt. Washington on July iith. Chion. 

 se?nidea were unusually abundant there this season, and their numbers 

 were remarked by all visiting there. Undoubtedly the best locality tor 

 them is the "Alpine Garden," about two miles from the summit on the 

 right of the carriage road (see Ento. Am., Vol. Ill, No. i, p. 12). The 

 majority taken were females heavily laden with eggs. Presuming these 

 were the first brood, emerging from July ist to the loih, it is reasonable 

 to suppose that a second brood is perfected before their season closes, 

 about the middle of August. How peculiar the habiis of this butterfly ! 

 In times of distress, they seek the rocks, and (ailing into the crevices 

 among small stones, they show the agility and nimbleness of spiders in 

 secreting themselves. On the 13th, a severe storm swept over the 

 mountain, the heaviest July storm for thirteen years. The wind travelled 

 90 to 120 miles an hour, and at times 140 miles. '1 he thermometer fell 

 to 24" F. , and snow was piled a foot deep, extending two miles below 

 the summit. The effect of this extreme weather on C. semidea was 

 scarcely perceptible, as far as their number was concerned, for after the 

 storm on the 15th, they were out as thickly as before, but badly broken 

 and worn. I found them also on neighboring summits, but not abund- 

 antly. 



I spent nearly two days on these summits in a fruitless search for 

 A7-g. montinus. Reports from other collectors preceding me this summer 

 were equally disappointing as to this butterfly. 



I took Lim. arthemis and Pap. turnus at an altitude of 6000 feet. 

 At an altitude of 400c feet one finds nearly all varieties of butterflies com- 

 mon to the valleys, flies, mosquitos, midgets, and other plagues almost 

 unknown 1000 feet higher. In the vicinity of "Crawford's," I found the 

 food plant of Met. phaeton and took several worn out specimens. 



Arg. atlaiitis was undoubtedly the commonest fly seen, with Lim. 

 arthemis a good second. Grapta J-alhwi, Colias philodice, and Pieris 

 rapie were scarce. As to Arg. monti?ius, I was greatly disappomted in 

 not getting some points of interest.
