THE CANADIAN ENTOMOLOGIST. 45 



Black Swallowtail,* in torn coiidilion. on Carbonear Island, a high rocky 

 islet, about a mile in length, lying off the mouth of the harbor, uninhabited, 

 uncultivated, partly covered with bushes — visited occasionally for summer 

 picnics. This is my first cabinet specimen ; but I had possessed an old 

 rubbed and patched specimen which had been c:aptured in the same 

 locality several years before 1 began to collect. 



jul\ 31. — -1 made a visit with A. E., to Carbonear Island. We saw 

 immense numbers of the little Orange-brown Butterfly (the Ccenonyinp/ia 

 figured on page 22 of my Entom. of Newfoundland, 4to), and many of the 

 Polyojnmatus {Argus of Ibid, p. 2-^).\ After searching the Island, in vain, 

 for a Swallowtail, we were just going down to our boat, when I caught 

 sight of a great black fellow fluttering over a bed of tansy. I ran towards 

 him, but I had to look about some time before I could find my beauty, 

 for he had now alighted, and was so fearless that he did not attempt to fly, 

 but continued sucking the aromatic flowers. 1 threw my net over him, 

 and found I had secin-ed a specimen much more perfect than my former 

 acquisition. 



Aug. 8. — My neighbor, Mr. Peters, gave me a beautiful caterpillar, 

 which had been feeding on parsnip in his garden, and a few hours later 

 he sent me another (No. 2), younger. They are of a clear a^jple-green 

 hue, each segment marked by a black transverse band of velvet-black, car- 

 rying five spots of bright yellow. Each segment is also separated from 

 its fellows by a narrower line of black. I feel confident they are the larv^ 

 of one of the Swallowtails. The No. 2 protruded, and instantly retracted, 

 a soft red organ from its neck. 



Aug. 9. — I observed the orange-colored organ of the neck much farther 

 projected ; it was then forked, in form of a Y ; it left a wetness on my 

 finger, and diff'used a strong odor of parsnip. 



Aug. II. — I am convinced that the Y-organ of the neck is used as a 

 defence ; for, on my touching the side of the caterpillar — the left side, for 

 instance — it would jerk its head roimd to the place, and protrude the left 

 branch of the forked horn : if I touched the right side, the right branch 

 would be protruded ; the other branch, on each occasion, being kept un- 

 displaycd, while a strong fetor was manifest. The cateri:)illar No. i has 

 moulted to-day.
