THE CANADIAN ENTOMOLOGIST. 



^in fig. 5. As the larva approaclies maturity it changes to a reddish brown 

 color, and after passing the third moult entirely loses the caudal horn, 

 which is replaced by a glassy eye-like spot. 'I'he mature larva when in 

 motion, as shown at a, fig. 5, will measure nearly four inches in length, but 

 when at rest it draws the head and two adjoining segments within the 

 fourth, as shown in the figure at b, which shortens its length nearly an 



inch, giving it a very odd 

 appearance with its anterior 

 portions so blunt and thick. 

 It is of a rich reddish brown 

 color, of a lighter shade along 

 the back, with five or six 

 nearly oval cream - colored 

 spots along each side from the 

 fifth to the tenth segments in- 

 clusive \ sometimes the spot 

 on the fifth segment is indi- 

 cated by a dot only, in other 

 instances entirely wanting. 

 On the anterior segments 

 there are a number of black 

 dots ; a dark polished raised 

 eye-like spot in place of the 

 tail ; stigmata black, showing 

 prominently in the cream- 

 colored spots along the sides. 



It is a very voracious feeder, 

 and where present strips the 

 vine so rapidly of its leaves 

 that it soon attracts attention. 

 When full grown it descends 

 and buries itself in the ground, 

 where it forms an oval cell within which it changes to a chrysalis. 



The chrysalis is of a chestnut brown color with the segments rough- 

 ened with impressed points, the terminal ring having a long thick spine. 

 The insect usually remains in the chrysalis state until the following sum- 

 mer, but sometimes it hatches the same season. In the 9th vol. of the
