HIPPOTION CELERIO. 123 



in the ground-colour. The first three segments are prolonged 

 anteriorly into a snout ; they are retractile within the 4th segment. 

 The horn on segment 1 1 is long and thin, red-brown with only 

 the tip black. The small head, the collar and the legs are likewise 

 red-brown, the prolegs lighter brown." The fullgrown larva is dirty- 

 brown, thickly covered with short black lines ; the 2nd, 3rd and 

 4th segments immaculate ; there is a large ocellus on the 5th 

 segment, and a smaller one on the 6th ; from this segment a pale 

 lateral stripe runs into the caudal horn ; the under parts, below the 

 spiracles, not freckled with black. [The larva, taken at Epping, 

 was too near its pupation for a good description to be made.] 

 (Doubleday, Ent., ii., p. 327). Moore notes (Lep. Ceylon, ii., 

 pi. lxxxiv., fig. 4, p. 16) : " Larva green or purplish-brown ; on 

 5th and 6th segments are two* round black ocellated spots dotted 

 with yellow, and encircled by a yellow ring, that on the 5th segment 

 the larger ; horn brown, slender and straight." The larva is brown ; 

 above the legs runs a yellow stripe in which stand the black- 

 margined spiracles. Above this, begins on the 6th segment, a 

 second, which terminates in the straight blunt anal point. On the 4th 

 and 5th segments stand on either side two circular black yellow- 

 margined eye-spots, having a white spot somewhat to the side 

 (Ochsenheimer, Die Schmett., ii., p. 205). 



Variation of larva. — There are brown and green forms of the 

 larva as in Eumorpha elpenor (Meade- Waldo). Four larvae taken at 

 Newmarket on vine in October, 1865 ; one was purplish-brown with a 

 brown caudal horn, the other three green with brown caudal horn. Each 

 had two spots on the 5th and 6th segments that near the head much 

 larger than the other ; these spots bright silvery, but, as the larvae 

 approached the pupating stage and became very dark, the spots 

 became quite black with a yellow rim round them (Postans, 

 E.M.M., ii., p. 162) ; two of these larvae were described on 

 November 9th as differing in colour, one being light brown and 

 one green, having an eyelet with a silvery pupil on the 4th and 

 5th segments, and a pale line extending from them to the horn 

 (Gaze, Ent., iii., p. 6). One of these four larvae is that figured 

 by Buckler (Larvae, &c, pi. xxv., fig. 2). The larvae are common 

 in November at Southport, in Queensland, feeding up before the 

 end of the month ; a green form of the larva is found commonly ; 

 Buckler figures only the brown one, which, however, is accurately 



* Hiibner's figure has ocellated spots on the 4th and 5th segments, and a 

 broad yellow line extending from the horn to the 6th segment, whilst it is 

 completely absent on the three front segments (Studies in Theory of Descent, 

 p. 193). In Buckler's figure [Larvae, Sec., pi. xxv., fig. 2) the ocellated spots are also 

 on the 4th and 5th (i.e., the 1st and 2nd abdominal) segments, but the subdorsal line is 

 wider on the thoracic and 1st and 2nd abdominal segments, and narrower on the 

 abdominals 3 to 8. In C. celerio, from India, as figured by Horsfield and Moore ('Cat. 

 Lep. Ins. East Lnd. Comp., pi. xi), the subdorsal line appears to have completely 

 vanished, whilst eye-spots are present on all the segments from the 4th to the 

 loth, their size diminishing from the head to the tail. The European form of 

 the same species has eye-spots only on segments 4 and 5, and Moore's later 

 description, here quoted, of the Cingalese larva of the species, agrees with the 

 European. One suspects, therefore, that that figured by Horsfield and Moore 

 may not belong to this species (refer, Studies in Theory of Descent, pp. 196-7). Ash 

 notes that Buckler's figure accurately portrays one form of the larva as found in 

 Queensland.
