120 THE CANADIAN ENTOMOLOGIST. 



dorsum on the thickened segments is smooth and rounded, but after a 

 few hours becomes flattened a Uttle, and corrugated ; 2 has a thin, high, 

 square topped ridge, the corners produced, and each bears a short thick 

 process, pilose ; on 12 are two short subconical processes, on 13 two like 

 them but larger, and these four form part of the two subdorsal rows, which 

 are almost suppressed on 6 to 10, but. are distinct on 11 ; the two dorsal 

 rows of tubercles are minute ; color of body yellow-brown, darkest on 

 posterior half, the anterior segments a little red-tinted ; the white lateral 

 band as before, but distinct, white ; the dorsum and upper part of the 

 side of 12 and 13 and a little of 11 pure white, the lower part of side 

 less pure, the shield sordid white ; over the white band, on 4, is a large 

 sub-oval black ocellus in a narrow yellow ring ; this ocellus is mostly 

 occupied by a prominent rounded black process with many short black 

 hairs on it ; head sub-cordate, finely granulated, shining yellow-brown, 

 with fine hairs. To next moult 2 days. 



After 2nd Moult — Length .36 inch ; same shape, and as before, the 

 dorsal area on thickened segments becomes corrugated and flattened and 

 depressed some hours after the moult, and the depression is enclosed by 

 an elevated oval rim ; 3 is a little excavated on dorsum on anterior part ; 

 2 is a square-topped ridge, but the processes have passed away ; on 1 2 

 and 13 the processes as at previous stage, but the rest of the subdorsal 

 rows have disappeared, and in place of part of them are slight rounded 

 elevations, like those of the dorsal rows ; so that on 3 there are two dor- 

 sal and two subdorsal rows of these knobs, but two dorsal only on 4, 5, 

 6 ; on 9 and 10 are two subdorsal little round filaceous spots ; color 

 yellow-brown to dark brown, the anterior parts having most yellow ; the 

 sides of the posterior segments of a black hue ; the white side stripes as 

 before; 12, 13 white, the shield greenish-brown above but white below, 

 and the anal claspers white ; the white extends into the sides of 11, but 

 the brown dorsal area runs back in a sharp point nearly to 12 ; on 4 the 

 eye-spot is large, flattened in front and there velvet-black, but behind this 

 is a prominent black vitreous bead-like elevation, smooth and without 

 hairs ; instead of a complete and uniform ring there is a thickening of the 

 yellow above and below the eye-spot, and the ends are narrowed, so that 

 the appearance is much like that of eye-lids _; head as before, and it and 

 segment 2 are one color, honey-yellow. To next moult 3 days. But one 

 larva, after 2nd moult, differed from all the rest, being uniform light yel- 

 low-brown, the white area on 1 1 and 1 2 yellowish.
