THE CANADIAN ENTOMOLOGIST. 11 



from 7 to lo and continued to ii and 12 is another derai-rovv, all very 

 short and pointing downward ; (this arrangement of the appendages con- 

 tinues to last larval stage) ; the dorsals are reddish, with a fiery glow, the 

 others are color of body ; 2 has a chitinous patch with fine tubercles and 

 hairs ; under side darker brown ; head subcordate, flattened frontally, 

 surface black, shining, much covered with fine and short black hairs. 

 Duration of this stage 3 to 4 days. 



After 2nd Moult — ^Length .22 inch ; shape much as before, the seg- 

 ments well rounded, each having one or two vertical depressions on the 

 side ; color chocolate-brown, with a reddish tint ; the appendages on side 

 of 2 much elongated, measuring .04, inch, and as the stage progresses 

 reaching .08 in.; the dorsals on 3 to 5 and 11 to 13 are longest, sub- 

 conic ; more or less of these dorsals are fiery red, sometimes a single pair, 

 and so to four or five pairs, and the others have a dull red hue ; head as 

 before. To next moult 3 to 4 days. 



After 3rd .Moult — Length .6 inch ; color silky black-brown; the dor- 

 sal appendages from 5 to 11 are bright red ; the front of the ridge on 2 is 

 of same red; the dorsals on 11 and 12 are curved forward; the long 

 side spur on 2 is now .16 inch, tapering and flexible. To next moult 4 

 to 5 days. 



After 4th Moult — Length .8 inch ; color now silky-black ; as the stage 

 proceeds it changes to dark brown, and loses much of its gloss. At about 

 five days after the moult the larva reaches maturity. 



MATURE LARVA— Length at rest 1.6 in., in motion 1.8 inch; 

 color uniform black-brown ; shape cylindrical, thickest at 4 and 5 ; each 

 segment curved, the highest point being in the line of the appendages, or 

 a little back of the middle of the segment ; furnished with several rows 

 of fleshy tapering appendages, bluntly rounded at top, and disposed as 

 before described under the first moult ; these are mostly concolored with 

 the body, and are thickly beset with short black hairs ; the dorsals on 3 

 to 5 are moderately long, on ri to 13 long, and the two last are bent 

 forward ; the rest are short ; from 3 to to they are bright yellow or some- 

 times orange-red ; of the anterior demi-row, the one on 2 measures about 

 .34 inch and is slender, ta[)ering, flexible, and is moved much Hke an 

 antenna ; the one on 3 is scarcely half as long as the other, and the two 

 on 4 and 6 are shorter still and equal ; on 5 resembles the short dorsals 

 and is colored like them, either yellow or red ; those of the posterior and 

 lower demi-row are bent down, and when the larva is at rest have their
