DEILEPHILA GALII. 39 



degrees these wrinkles were smoothed out as the 

 creature grew, and the final dress was assumed. 



I shall now describe this same larva when mature, 

 and then give notes of the chief varieties which came 

 under my notice. 



Length, when stretched out, two inches and seven- 

 eighths. The back and sides of deep bronzy olive- 

 green, but below the spiracles and on the ventral sur- 

 face the colour is a smoky deep purplish-pink ; 

 although the boundary is clearly defined, yet a gleam 

 of the one colour tinges almost imperceptibly the 

 other, both above and below. 



There is no subdorsal line, but in its place a row of 

 fourteen somewhat roundish spots ; four of them on the 

 thoracic segments are small, the others large, the 

 hinder one somewhat pear-shaped, pale golden-yellow 

 in colour, and set in transverse ovals of deep black, 

 which melt into the ground colour ; the spiracles 

 yellow, outlined with black, and surrounded by a cloud 

 of darker olive than the ground colour ; a few small 

 yellow specks are sprinkled along the sides. One can 

 well make out a thin dorsal stripe of deep ochreous- 

 olive, wide at the beginning of each segment, looking 

 as if it were showing dimly through the surface from 

 a depth below. The head is purplish-pink, the mouth 

 black, with a streak of pale yellow above it and yellow 

 bases to the papillae, and just above them is a narrow 

 circumferent band of black. The plate on the second 

 segment, the anal flap, and the prolegs are dark 

 pinkish-red ; the anterior legs black, the ventral pro- 

 legs purplish-pink, with an outward bar of black near 

 their extremities ; the horn is semi-translucent and 

 blood-red ; the whole surface of the skin, excepting 

 on the thoracic segments, is now brilliantly polished, 

 and resplendent with the play of light at every move- 

 ment. 



Taking the above as my type, I could make two 

 grand varieties as to ground colour — the pale olive 

 and the black ; and each of these — as well also as my
