Is. The colour, when once wen, iu recognized again, even on the wing, at once. The 

 •clear brimstone yellow, and the conspicuous triple frinpe. |>iuk with a carmine streak in 

 the centre, and the perfectly immaculate underside, make it a great favourite with all who 

 have seen it in its native wilds. From this |>oint, westward to Port Arthur, on f^ake 

 Superior, and eastward as far as Lake Nipissing, this beautiful species is abundant. 

 During the afternoon we took nine specimens, all newly emerged males. To get to the 

 ridge we struck off from the railway in a north-easterly direction, across a sphagnous bog. 

 We found no insects of interest in the hog, although there was a profusion of flowering 

 plants ; the wild roses being very beautiful. We at last reached the ridge, and found the 

 sides very precipitous. After a time, however, we came to the dry \ied of a stream, and 

 tjlimbing up through the tangled growth of spiked maple, cedar, vibamuni and cornel, we 

 gained the top after a hard climb ; here we found the vegetation much parched ; flakes 

 of moss slipped from the bare rocks as we trod upon them, and the leaves of trees and 

 bushes were faded and drooping. In every shaded crevice grew mosses and bog plants — 

 glorious Cypripfidiums (G. acauln and C. parvijiorum), which it was impossible to pass 

 bj. Upon the bare, exposed rocks, in some places, grew patches of Potentilla tridnntala, 

 now in blossom, and the only flower growing out in the o[>en snnshine. Uere we took 

 some more specimens of the little skipper, like P. Manitoba. They were very difficult 

 to take, and when once disturbed, dashed off over the edge of the cliff. One speci- 

 men of Ch. Macounii was taken on the top of the ridge, after a most exciting chase. 

 It rose from a wet bog some distance from the brink of the clilf, and ws were sure that 

 ■we had a specimen of C. Jutta, which species Professor Macoan had taken here at this 

 time of the year. Nothing else of any particular interest, with the exception of some 

 sub-arctic plants, was foun(i on the ridge. Luthyrus ochroUueus, the Pale-flowered Ever- 

 lasting pea was noticed in the rocky woods as we descended, and was noted as a possible 

 food-plant of Colias Interior. 



12th July. This was our last day, and wn had a ijood deal to do before we left. 

 Our cages had all to be examined, the eggs collected and packed, and the start for homa 

 to be made. In collecting butterflies for the cabinet, if good specimens are desired, it is 

 necessary to kill them in a cyanide bottle. This is easily made, either by putting a 

 small quantity of cyanide of potassium in a wide-mouthed ijottle, or by cutting out a hole 

 in the cork and putting a piece of the poison in the cavity. A convenient bottle I use 

 myself, is made in this manner : the cyanide is kept in place by a piece of chamois 

 leather, which entirely covers the cork, and is tied over the top like the mouth of a sack. 

 I leave about an inch of the leather above the tie, and this is very convenient for holding 

 the bottle, or extracting the cork with your teeth when both hands are occupied. But 

 as cyanide of potassium is a deadly poison, great care rnxuX be tak«;n not to get any of it 

 tipon the 1( ather. By this upper portion, too, the cork is easily tied to the neck of the 

 bottle, a precaution which will frequently save much annoyance and trouble, especially 

 when mosquitoes are troublesome. A further precaution, which has many times been of 

 service to me, is to tie a short piece of bright scarlet cloth to the neck of the bottle. It 

 IS a much easier matter than some would imagine to drop, lose, or even forget your 

 cyanide bottle when stopping frequently to put away specimens, or make notes. Many 

 times have I found a lost bottle by this means. When specimens are thoroughly dead, 

 they should be taken from the poison bottle and dropped into envelopes. If left in the 

 bottle they soon become rubbed and spoilt. Some sp<^cimens when dying, instead of 

 closing their wings, opon them right out tmtil the two undersides meet. These may be 

 left aa they are, because the underside of every species must be shown in a collection. If, 

 however, it is d sired to close the wings, they should be taken out of the cyanide bottle, which 

 makes them ri^'id, and left for a few hours, when the muscles will relax ; or, on the other 

 band, they may be left in the poison bottle for 24 hours, or longer, and the same thing 

 will take place. This List plan, however, is not a good one. The envelopes for lepidop- 

 tera are made by taking small squares of paper and folding them across, almost in the 

 middle, so as to make a triangular form with one flap a liitle smaller than the other. 

 When the insect is placed between the two flaps, the two edges of the larger one are 

 folded over the lesser, and your insect is now ready to be labelled and packed away. Small 

 ■^igar boxes are very convenient for carrying lepidoptera, or for sending them by mail.
