^'"- «■ The caterpillars 



of lincata vary 

 mucli in appear- 

 ance. In Fig. 6 we 

 lavc a represen- 

 tation of the innst 

 common form, 

 while another 

 form is shown in 

 Fig. 7. They 

 are said to feed 

 upon purslane, 

 turnip, buck- 

 wheat, water- 

 melon, also on 

 grape and apple 

 leaves. IMr. Pile, 

 of Dundas, Ont., 

 has found them 

 feeding on the 

 common plantain. 

 They arc found in the larval condition during the month of July, and when full grown they 

 are said to descend into the ground, where they change into light brown chrysalids, and ap- 

 pear as moths in September. 



The following description of the larva of B. cfuinujenerii was made from three examples 

 found feeding on grace leaves on the 5th of July :— 



Length, two and a half inches, tapering towards each end : head small, rather flat in 

 front, slightly bilobed, and of a dull pinkish colour, with a black stripe across the front at 

 the base ; basal half of palpi yellow, upper half black ; mandibles black, with a patch of 

 yellow between them and the black stripe. 



Body above deep olive green, with a brownish tinge and a polished surface. Second 

 segment with a cervical shield similar in colour to head, its sides dull greenish, with two 

 yellow dots. There is a pale yellowish dorsal line terminating at the base of the caudal 

 horn ; each segment from 3rd to 12th, inclusive, has a pale yellow spot on each side of the 

 dorsal line, about half way towards the stigmata, those on 3rd segment small and almost 

 crescent-shaped, on the 4th larger and nearly round, 5th still larger, nearly round, Gth, 

 7th, 8ih, 9th, lOtli and 11th about equal in size, nearly oval and larger than those on ."ith. 

 On 12th segment the spot is more elongated, and extending upwards, terminates at the 

 base of the caudal horn. There is a wide but indistinct blacki.sh band across the anterior 

 part of each segment, in which the yellow spots are set ; the sides of the body below the 

 spots are thickly sprinkled with minute raised yellow dots. Caudal horn long, curved 

 backwaids, red, slightly tipped with black, and with a roughened surface ; terminal seg- 

 ment (hill pinkish ; stigmata oval, yellow, shailed around with dull black. 



Under surface much paler, colour dull pale pinkish green, the pink colour predomi- 

 nating from 5th to terminal segments inclusive, ami with a number of very minute raised 

 yellowish .lots placed chiefly along the sides. Feet black ; pro-legs pink, with a patch of 

 black on the outside of each. One specimen spun a light web, binding a portion of the 

 leaf in the manner of pampinalru:, within which it changed to chrysalis on the 10th of 

 July, and from this the imago appeared on the 2Sth of the same montli. The other two 

 larvae died before completing their transformations. 



The Black Swallowtail Butterfly {Fapilio asterias). 



This is one of our commonest butterflies, and is found in nearly all parts of Canada 

 and tht' United States. It is a very handsome species, with the wings of a black or deep 

 blackish brown colour, with yellow and blue markings. Across the wings there are two 

 bands of yellow spots ; those composing the inner one in the male are large and distinct, 

 while in the female they are smaller and .sometimes almost obsolete. In Fig. 10, also
