Larv/E of S. Ocellatus. — After more 

 than twenty years collecting, I have this 

 year made the acquaintance of this larva 

 for the first time; By book descriptions 

 there seemed very little difference between 

 it and that of populi, except that the horn of 

 ocellatus was said to be blue. Even the 

 figures I have met with show no striking 

 difference between the two except in colour. 

 Miss Hinchliffe, of Inston, has sent me a 

 supply of ocellatus larvae, and I confess I am 

 surprised after believing them to be so like 

 3ach other, to find so much difference. 



Populi is a bright green colour, with greenish 

 yellow diagonal stripes, and a yellow horn. 

 Ocellatus is a whitish blue, with similar stripes 

 of a paler whitish blue, and with a longitu- 

 dinal stripe extending from the first of the diagonal 

 ones to the head. Of this there is no trace in 

 populi. There is a variety of populi larvae 

 very much resembling ocellatus in colour, but 

 this stripe is a distinct and easily noticed 

 difference. Besides this, the face differs, 

 that of ocellatus being larger and flatter, and 

 pointed at the top, and with an orange or 

 orange yellow marginal ridge, which termi- 

 nates in two little orange-coloured points,
