Fig. 45. Deilephila Galii; Stage IV. Subdorsal with open ring-spots. Natural length, 3.4 centim.
Fig. 46. D. Galii; adult larva; Stage V. Brown variety with feeble shagreening; subdorsal completely vanished. Natural length, 6 centim.
Plate VI.
Fig. 47. The same species at the same stage. Black variety strongly shagreened; similar to Deil. Euphorbiæ.
Fig. 48. Similar to the last. Yellow var. without any trace of shagreening.
Fig. 49. Deilephila Vespertilio. Three stages in the life of the species, representing three phyletic stages of the genus. A, life-stage III.=phyletic stage 3 (subdorsal with open ring-spots); B, life-stage IV.=phyletic stage 4 (subdorsal with closed ring-spots); C, life-stage V.=phyletic stage 5 (subdorsal vanished, only one row of ring-spots).
Fig. 50. Deilephila Zygophylli, from S. Russia; stage V. From a blown specimen in Staudinger’s collection. In this specimen the ring-spots are difficult to distinguish on account of the extremely dark ground-colour; they are nevertheless present, and would probably be more distinct in the living insect. A, open ring-spot from another specimen of this species in the same collection.
Fig. 51. Deilephila Nicæa, from South France; Stage V. Copied from Duponchel.
Fig. 52. Sphinx Convolvuli; Stage V., segments 10–8. Brown variety, with distinct white spots at the points of intercrossing of the vanished subdorsal with the oblique stripes.
