standing above the crown of the head. These 

 differences — the side stripe, and the two 

 little tips projecting above the top of the 

 angular face — are enough to guide any one. 

 There are other more minute differences 

 which I may describe on another occasion, 

 but I thought it worth while to point out these 

 guides to their discrimination now, when 

 both larvae are feeding. In this part of the 

 country ocellatus is exceedingly rare, having 

 seldom been taken, and so far as I know 

 only once bred, when the difference had 

 never been noticed in the larva. — John E. 

 Robson, West Hartlepol. 



M. Stellatarum. — I took a female of the 

 humming bird hawk moth flying on the 

 railway side on Saturday last. It is a female 

 much worn, and seems to have deposited all 

 its eggs. I understand it is many years 

 since it was taken here before. —J. J. Cam- 

 bridge, Hartlepool.
