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.

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.
