40 DE1LEPHILA GALII. 



dark olive type — furnished a further subdivision 

 through variation in points of detail. 



Var. 1. — Neither a light nor a dark olive-green, but 

 between them, with the large yellow spots developed 

 into pear shapes, the small end of each projecting for- 

 wards as a spot on the segment in advance. 



Var. 2. — Dark reddish-brown, with just a tinge of 

 olive, and with the addition to the usual obscure dim 

 dorsal line of a bright pale ochreous mark at the 

 beginning of each segment, terminating at the end of 

 the broad first subdivision, which appears like a black 

 band ; the bright yellow subdorsal spots as before. 



Var. 3. — The ground colour of the back and sides 

 a pale brownish ochreous-olive ; the subdorsal pale 

 primrose-yellow spots, and the spiracles environed 

 with black ; the belly and prolegs rose-pink. 



Var. 4. — A deep jet-black on the anterior segments, 

 bluish-black on the others ; the head, thoracic plate, 

 and anal extremities of very dark purplish-red ; the 

 subdorsal spots of a dirty and dingy yellowish- drab 

 tint, with their centres more or less filled up with 

 blackish-brown, in one or two instances wholly oblite- 

 rated. 



Var. 5. — Ground colour entirely bluish-black, the 

 deepest tinge of purplish-red on the head, the plate 

 behind, and the anal extremities ; blotches appear on 

 the side of the anal flap, which, with the subdorsal 

 spots, the spiracles, and an extensive irroration of 

 small dots, are all of the purest pale golden-yellow, 

 the black ground being left unbroken as a band across 

 the back from one subdorsal spot to the other. 



Concluding my own remarks, I may state that in 

 every instance the skin after the last moult was black 

 for a day or two, as previously mentioned ; but at this 

 time one may judge of the colour the larva will even- 

 tually assume, by the tint of the head, thoracic plate, 

 and anal extremities ; these parts, if then quite black, 

 indicate that the ground colour will be black to the 

 end of its career ; but if they are of deep purplish-red,
