Sphinx pinastri. 

 Plate XXII, fig. 3. 



On the 26th of July, 1882, I received from Herr 

 Ernst Heyne, of Leipzig, a dozen eggs of this species, 

 laid loose. 



These eggs were as large as those of Smerinthus 

 populi, but not so round, the shape being roundish 

 ovate ; they were smooth and glossy, and their colour 

 at the time I received them was a light greenish- 

 ochreous-yellow, or pale olive-yellow; some were 

 clouded within with brown, in some instances with 

 quite dark brown at one end ; the shell had a pearly 

 lustre. Before hatching the dark lobes of the em- 

 bryonic head were distinctly visible at one end. 



The first egg hatched on the 29th of July; the 

 young larva was of a light greenish-ochreous, with 

 the two lobes of the head broadly marked with dull 

 black-brown ; the anterior legs were black, the ventral 

 prolegs were barred outside with dark brown just 

 above the feet, the caudal horn, which was a little 

 flattened and slightly bifurcate at the tip, was dull 

 brownish-black ; a faint brownish dorsal line was just 

 visible. 



Another was hatched in the evening of the 31st of 

 July, two in the evening of August 1st and three by 

 the morning of the 2nd, two more in the evening and 

 one at night of the same date. 



After feeding for two or three days on Pinus ,* 



the body became greener and showed faintly paler 

 green subdorsal lines and a faint yellowish spiracular 

 line. 



On the 5th of August some were laid up to moult, 

 their skins shining green, with the front edge of the 

 second segment pale cream colour, in striking contrast 

 to their copper- coloured heads, marked with blackish 



* The species of Pinus is not given in Mr. Buckler's note-book, a 

 blank being left for it.— H. T. S.
