30 SPHINX PINASTRI. 



and behind with deep red, the latter bordering being 

 broader below and shading above gradually into the 

 ochreous-green colour of the back of the head. 



By the 3rd of September this larva had grown to be 

 3 inches and 2 lines when stretched out, and the white 

 stripes were becoming interrupted in the middle ; the 

 front edge of the second segment next the head was 

 of a dark-blue green, and a streak of shining reddish- 

 black was situated in front above the base of each of 

 the anterior legs. 



On the 5th of September the larva which I had 

 figured ceased feeding about noon and began wandering 

 about for a little while ; soon afterwards it burrowed 

 into the earth. Another larva was at the same time 

 very busy covering its skin all over with some fluid 

 discharged from its mouth (reminding me of a cat 

 licking himself) ; in the course of another hour this 

 had also gone into the earth. This proceeding was 

 within a week followed by all the other larvae. (W. B., 

 Note-Book IV, 147.) 



DEILEPHILA EUPHORBL3E.

In 1859 I figured this species from a larva sent me 

 by a correspondent in Jersey, but, none the less, I was 

 desirous to see a living example again, for in the 

 interval I knew that my eyes had been educated con- 

 tinually to see more and more in my subjects, and I 

 felt I might then have passed over something in such 

 a difficult task which I could now detect at once. 



My surprise, therefore, was more than equalled by 

 my delight when on the 7th of August, 1872, there 

 came to me four larvse, which a few days before had 

 been found feeding on Euphorbia cyparissias in the 

 Forest of Fontainebleau by Mr. Evan John, whose kind- 

 ness in taking the pains to bring them to England as a 

 contribution to my work I remember most gratefully.
