DEILEPHILA EUPHORBIA. 35 



divisions in the subspiracular region ; the black plate 

 on the second segment was margined with red; the 

 red head and the dorsal stripe, &c, were as in the 

 other varieties. 



The black variety had no subdorsal wedge marks ; 

 the first ring in each segment had a black ground, the 

 others a greenish-black ground, dotted and spotted 

 with bright sulphur-yellow above, and white below; 

 very little of the subspiracular region was inflated, 

 it was coloured crimson-red and ochreous, the red in 

 the middle gently blending with the ochreous at each 

 segmental division; the anterior edge of the second 

 segment was yellow, a large round black spot on the 

 top of each lobe of the crimson head. The anterior 

 half of the anal prolegs was black, the rest crimson ; 

 the crimson dorsal stripe quite narrow; the anal flap 

 was black margined with crimson. 



I must not omit to mention a handsome variety of 

 this larva, brought home in spirits from Cairo by Mr. 

 Jenner Fust, which I thankfully received in May, 1871, 

 through my friend Mr. Hellins and figured. This had 

 the broad ring on each segment black, the ground 

 colour of the others of the deepest blackish-olive, the 

 head, the plate on the second segment, the dorsal 

 stripe, the legs, anal flap and caudal horn, were blood- 

 red. The double series of large spots were creamy- 

 whitish ; the upper rows of small dots pale yellow, the 

 lower rows white; the subdorsal truncated- wedge 

 shapes were of deep ochreous and largely developed; 

 the inflated subspiracular region, belly and ventral 

 prolegs, of deep ochreous or buff colour, the latter 

 tipped with red; a pear-shaped blotch of dark olive 

 dotted with white was situated below the subspiracular 

 region on each segment ; the anterior legs red. 



The cocoons were of a very firm texture, spun with 

 strong and coarse silk threads attached to some leaves 

 of spurge above and with some sand interwoven, and 

 in each instance firmly fastened to the side of the pot, 

 and sunk about half an inch below the surface of the
