156 ' THE CANADIAN ENTOMOLOGIST. 



except that in the lower lateral row, from 6 to lo, there is a little orange 

 on the outer side of each tubercle ; the small spines of row along base are 

 orange, from orange tubercles ; segment 2 has a black chitinous dorsal 

 collar on which are many small black spines, with hairs; feet black; pro- 

 legs black, the last joint yellowish ; head ob-ovoid, flattened frontally, de- 

 pressed at suture, the vertices rounded ; color dull black, the surface 

 rough, thickly covered with long black hairs. 



On 2nd May, one larva passed the first moult after hibernation, the 

 supposed fourth moult. At 24 hours from the moult : length A inch. 

 By loth May, this larva had reached maturity. 



Mature Larva. — Length .9 inch ; cylindrical, thickest in middle ; 

 color black, with a slight dorsal band of gray-white, made up of white 

 tubercles on the cross ridges, and a heavier band of same color along 

 lower part of side, the black area between the two being thinly dotted 

 white ; the spines long, stout at base, tapering, and thickly beset with long 

 black hairs ; those of dorsal row black at tips, the rest and the large basal 

 tubercles, yolk-yellow; those of the other three rows black, the bases 

 black ; the small spines along base of body yolk-yellow on 6 to 10, the 

 rest black ; on 2 a chitinous collar with many small black spines with 

 hairs ; feet black, pro-legs black, the last joint yellowish ; head ob-ovoid, 

 flattened in front, depressed at top, the vertices rounded ; surface rough 

 with many long, black hairs ; color dead black. 



On 1 2th the larva suspended, and at 8 p. m., 13th, pupated. From 

 last moult to pupation 11)^ days. (In case of other Melitaeas, two 

 moults have occurred between hibernation and pupation.) 



Chrysalis. — Length 1% inch; breadth across mesonotum and abdo- 

 men tVt in. ; shape of Phaeton ; cylindrical ; head case narrow, compressed 

 transversely, excavated at the sides ; mesonotum not prominent, rounded, 

 somewhat carinated, followed by a shallow excavation ; the tuberculations 

 which correspond to the larval spines and tubercles rounded, raised but 

 little above the surface ; color of anterior parts and wing cases dark 

 pearl-gray, marked and spotted with black ; of abdomen diluted black 

 dotted with dull white, especially along mid-dorsum, and across same, on 

 the posterior part of each segment, where the dots form parallel rows ; the 

 mid-dorsal tubercles orange, making a round spot on the fore part of each 

 segment, and on each spot are two small black spots in cross row ; in line 

 with the spiracles, on the anterior side of each, is a slight orange discol-
