THE CANADIAN ENTOMOLOGIST. 47 



across the middle of tlie wing-covers. The skin was as yet so soft, and 

 the silk so slender, that it cut into the wing-covers, so far as to be in- 

 visible ; l)iit. as all my specimens are alike in this respect, I presume it is 

 no other than natural. The shape of each was different, immediately on 

 expulsion, from what it became after some hours ; the fore parts being 

 awkwardly shortened and shrivelled, and the hind wings stretched out. 



Aug. 27. — Caterpillar No. 2 finished his girth, and put it over his 

 head, about 8 a. m., and so is suspended. 



Aug. 30. — This No. 2 went into pui)a in the early morning. In this 

 case when the skin was stripped down, the tail was not put out to take 

 hold of the silken knob ; and, by and by, the old skin loosed its hold of 

 the silk, and the chrysalis was swinging about, suspended only by the girth. 

 I proceeded carefully to assist nature by removing the old skin, and put- 

 ting the tail to the silk, of which its projecting points now took firm hold. 

 The girth, however, remains between the sixth and seventh rings, so as to 

 cause the fore parts to hang down considerably. In shape it resmbles the 

 other three ; but in color it is widely different, being wholly of a bright 

 yellowish green, except a wide band of pale yellow down the back. This 

 individual is the one which, as a larva, had the peculiarity of the yellow 

 spots, which I noticed on the i6th inst., and from both circumstances, I 

 fully expect the imago to be of a different species from the others. 



1835. J'^ii'^e 25. — To-day I sailed from Carbonear for Canada, carrying 

 with me the four Swallowtail chrysalids of last summer, all alive and 

 apparently healthy. . 



July 4. At sea, in the Gulf of St. Lawrence. — From the yellow and 

 green chrysalis, No. 2 (see note on Aug. 30, 1834), was evolved before 

 day, a specimen of the Black Swallowtail — Papilo Asterias {brevicauda of 

 Saunders.) It is identical with the examples taken on the Island last 

 summer, but in great beauty of perfection ; the wings are not in the least 

 injured from the cutting of the pupa-skin l)y the girth (see Aug. 25, 1834), 

 nor by the accident that the girth has been, for some weeks past, broken ; 

 one side first giving way, then the other, so that the chrysalis has been 

 hanging perpendicularly. 



July 14th. — One of the drab-hued, brown-striped chrysalids produced 

 the butterfly this afternoon. 



July 18 and 20. At Quebec. — The other two were evolved. Those 

 of the 4th and 14th had been kept in glasses, exposed to the sunlight, all
