276 THE CANADIAN ENTOMOLOGIST. 



Length of second stage about nine days. 



On 2ist July one was found to have passed second moult. 



After Second Moult. — Length at rest, 7.8 mm. Processes innumer- 

 able. Shape as before, tail as before ; head as before, very rounded, 

 exceeding the second segment, light horn coloured, translucent, much 

 pitted. Colour of body, yellowish-brown. A strongly marked dark 

 brown or black dorsal stripe, bordered with creamy colour, three brownish 

 lateral stripes, the upper one light brown, the middle one dark brown with 

 a light brown shading below, the lowest one light brown and very little 

 separated from the shading of the middle one. Spiracles small, ringed 

 with brown. Subspiracular ridge strongly marked and below it a dark' 

 brown stripe. The sockets of the prop-legs and feet margined with brown. 

 Venter, prop-legs and feet of same light horn colour as above, the feet 

 and legs speckled with brown dots. 



On 31st July one which had lagged very much was found partly past 

 second moult, but dead ; one still lingered, not having moulted ; several 

 were nearly ready for third moult. On 2nd August one was fo.und just 

 past third moult, and the second moulted on the 3rd. 



Length of third stage was thus about twelve days. 



After Third Moult. — Length, 11.46 mm. Edwards says .38 inch. 

 Colour is greenish-brown, and the only difference I could see was that the 

 upper lateral or subdorsal stripe is darker than before. The third larva 

 moulted soon after 3rd August, and the fourth on 8th August and fifth on 

 13th August. 



After third moult they increased very rapidly in size and became 

 very plump, as I supposed, preparatory to hibernation, as Edwards de- 

 scribed four moults, but I soon recognized that they must be about to 

 pupate. 



Mature Larva. — Length, 20.3 mm.; pale greenish-horn colour; tapers 

 to both ends. 



Head rather small, pale horn-colour, tliickly and minutely pitted with 

 brown. Dark brown dorsal stripe, bordered with creamy colour. The 

 other stripes rather faded out and indistinct. Rather more than halfway 

 to the spiracles there is a creamy stripe margined below with brown and 

 with a slight brownish atmosphere above. The spiracles are dark brown 

 and very small, and just above them there is a pale creamy line. The 

 subspiracular fold is strongly marked, but the dark line below it has 

 almost disappeared and is only represented by a slight shading. Before
