Note 166 — Part II. ON THE FINAL CAUSES OF TRANSFORMATION. (continued 3)

[In the following species, already mentioned in previous notes, the oblique stripes are bounded at their upper extremities by a conspicuous subdorsal line:—Acosmeryx Anceus, Cram.; Sphinx Cingulata, Fabr.; Pachylia Ficus, Linn.; P. Syces, Hübn. In Pseudosphinx Cyrtolophia, Butl., the oblique white stripes, beautifully shaded with pink, run into the white pink-bordered dorsal line, so that when seen from above the markings present the appearance of the midrib and lateral veins of a leaf, and are probably specially adapted for this purpose.
