Figs. 17-22. Development of the markings in _Chærocampa Elpenor_.
Fig. 17. Stage I.; larva one day after hatching. Natural length, 7.5
millim.
Fig. 18. Stage II.; larva after first moult. Length, 9 millim.
Fig. 19. Stage II.; immediately before the second moult (Fig. 30
belongs here). Length, 13 millim.
Fig. 20. Stage III.; after second moult. Length, 20 millim.
Fig. 21. Stage IV.; after third moult (Figs. 32 and 33 belong here).
Length, 4 centim.
Fig. 22. Stage V.; after fourth moult. A feeble indication of an
eye-spot can be seen on the third segment besides those on the fourth
and fifth. Ocelli absent on segments 6-10.
Fig. 23. Stage VI.; after fifth moult. The subdorsal line is feebly
present on segments 6-10, and very distinctly on segments 11 and 1-3.
Ocelli repeated as irregular black spots above and below the subdorsal
line on segments 6-11; a small light spot near the posterior border of
segments 5-10 (dorsal spots) and higher than the subdorsal line. Larva
adult.
Figs. 24-28. Development of the markings of _Chærocampa Porcellus_.
Fig. 24. Stage I.; immediately after emergence from the egg. Length,
3.5 millim.
Fig. 25. Stage II.; after first moult. Length, 10 millim.
Fig. 26. Stage III.; after second moult. Length, 2.6 centim.
Fig. 27. Eye-spots at this last stage; subdorsal much faded, especially
on segment 4. Position the same as in last Fig.; magnified.
Fig. 28. Stage IV.; after third moult; corresponds exactly with Stage
VI. of _C. Elpenor_. Dorsal view, with front segments partly retracted
(attitude of alarm). Ocelli on segment 5 less developed than in
_Elpenor_; repetitions of ocelli as diffused black spots on all the
following segments to the 11th; two light spots on each segment from
the 5th to the 11th, exactly as in _Elpenor_; subdorsal line visible
only on segments 1-3. Length, 4.3 centim.
Fig. 29. _Chærocampa Syriaca_. From a blown specimen in Lederer’s
collection, now in the possession of Dr. Staudinger. Length, 5.3
centim.
Fig. 30. First rudiments of the eye-spots of _Chærocampa Elpenor_,
Stage II. (corresponding also with Fig. 19 in position, the head of
the caterpillar being to the left). Subdorsal line slightly curved on
segments 4 and 5.
Fig. 31. Eye-spots at Stage III. of the larva Fig. 20 somewhat further
developed (larva immediately before third moult). Position as in Fig.
20.
Fig. 32. Eye-spots at Stage IV. corresponding to Fig. 21, A being the
eye-spot of the fourth and B that of the fifth segment.
Fig. 33. Eye-spot at Stage V. of the larva of _C. Elpenor_; fourth
segment.
Figs. 30-33 are free-hand drawings from magnified specimens.
