Description of the Larva of Deilephila Galii. — The head 

 is rather wider than the 2nd segment, and also rather wider 

 at the mouth than on the crown ; the head emits a number 

 of rather stiff bristles directed forwards : the body is stout 

 and cylindrical, evidently attenuated towards the head when 

 the larva is stretching itself out either to feed or crawl ; the 

 12th segment is the stoutest, and emits a scabrous dorsal 

 horn which is slightly curved ; the horn differs in length in 

 different specimens; in some it is very short and stumpy, 

 while in others it forms a regular and rather elegant curve, 

 and every intermediate gradation of form occurs : each seg- 

 ment may be described as being composed of two divisions, 

 the first flat and unwrinkled, the second transversely 

 wrinkled, or perhaps,' speaking with more precision, trans- 

 versely divided into sections, the last of which is rather 

 wider than the others : the anal flap and anal claspers, as 

 well as the ventral surface of the 5th and 6th segments, are 

 beset with short stiff bristles. The colour is various : in 

 three specimens I have before me the ground colour is dull 

 black, but 1 am aware that the tone of the ground colour 

 varies in intensity, sometimes being so light as to approach 

 a pale wainscoat-brown ; the three specimens vary in other 

 respects. 



A has a red head and horn ; a narrow raedio-dorsal stripe 

 of pale canary-yellow ; a lateral series of ten rose-coloured 

 spots on each side, nine of which are nearly circular, and 

 the tenth somewhat pear-shaped, the smaller extremity 

 extending to the base of the caudal horn ; and a narrow 

 lateral stripe in the region of the spiracles almost white. The 

 rose-coloured spots are connected by a series of smaller 

 yellow spots, five of which intervene between each two of 

 the former, thus forming a continuous series of spots, which 

 commences on the 3rd segment and terminates at the base of 

 the coral-red horn. After moulting the dorsal stripe disappeared.
