28 THE CANADIAN ENTOMOLOGIST. 



ward. General color carnation, with a medio-dorsal line, and three lines 

 on each side, all of crimson. After ist moult the color is green, and the 

 stripes, which are the same in number and position as the lines of first 

 stage, are dark green ; the hairs short and straight. 



After 2nd moult the color becomes yellow-green and the stripes are 

 changed. There is now a dark green one on middle of dorsum and a 

 yellow one covering the ridge over the feet. On 24th March, I compared 

 Hoboken A /ope, Hunter and Illinois Nephele, of same age, all lately past 

 second moult, and could see no difference whatever between them. Some 

 A/ope and Hunter Nephe/e were much covered with long hairs which were 

 bent to the surface and gave them quite a shaggy appearance. But others 

 did not show this peculiarity. 



On 1 8th April, I compared Coalburgh A/ope and Nephele from both 

 localities, all past 3rd moult ; length from .68 to .75 inch. All were 

 yellow-green and in general alike ; all had the yellow basal ridge, but in 

 addition to this, the Illinois Nephele had a distinct longitudinal yellow 

 stripe on upper part of side, and on either edge of the green dorsal stripe 

 was a fine yellow line. The Hunter Nephe/e showed very faint traces of 

 the yellow side stripe ; the Alope none at all. 



Comparing another Coalburgh Alope and Hunter Nephele a few days 

 later, both past 3rd moult, neither showed traces of these lines and I 

 could see no difference between the two. 



At 4th moult all the Illinois Nephele, now .7 inch long, showed same 

 peculiarities as at last stage. No other larva of the several lots presented 

 the yellow lines so plainly at the same age, that is, just after the moult ; 

 but there were one or more A/ope and Hunter Nephele which gave indi- 

 cations of the side line, and this came out more distinctly as the stage 

 progressed. But most were without the side line. 



Comparing mature larva? : 

 One Albany Alope, length 1.25 inch, greatest breadth .16 inch ; color very 

 yellow-green, no yellow side or dorsal stripes or lines. 



One Coalburgh A /ope, length 1.6, gr. br. .2 inch ; color yellow-green, the 

 side more green than dorsum ; a yellow side line, quite indistinct. 



Hunter Nephele. 3 examples ; length of one 1.2 inch, gr. br. .15 inch ; of 

 another 1.15, br. .16 inch. Two were yellow-green, of same shade 

 as nearly all the Coalburgh larvae. One was more decidedly
