[309] Some few subcutaneous larvæ have more, as that, before mentioned, observed by De Geer in the leaves of the rose; which has eighteen prolegs, and no true ones.
[310] De Geer ii. _t._ xl. _f._ 15, 16. Bergman has added to these four classes of the larvæ of saw-flies, a fifth; the insects belonging to which, he affirms, though they have sixteen prolegs, are without the anal pair. Ibid. 931. But as neither De Geer nor Reaumur ever met with one of this description, it is probable he was mistaken. Reaumur thought he had seen one with eighteen prolegs upon _Erysimum alliaria_ (v. 91), but he does not speak positively.
[321] Ibid. 31. This larva has also a pair of pediform processes at the anus, surrounded at the end with claws (_t._ v. _f._ 4, 5, _s s_), which he saw the animal use in locomotion; but which he suspects to be respiratory organs (Ibid. 33), which Latreille asserts they are. _Gen.

[327] I have a caterpillar, I believe from Georgia, in which this horn is nearly an inch long, filiform, slender, and tortuous.
[329] That of _Sphinx Iatrophæ_ L. appears to be jointed, at least it is moniliform. Merian _Surinam. t._ xxxviii. Compare also _t._ iii.

[338] Ray says he found it feeding on common fennel, about Middleton in Yorkshire: _Lett._ 69. The indefatigable Mr. Dale recently found many in the neighbourhood of Whittlesea-mere, feeding on _Selinum palustre_. It will also eat the wild carrot.
[339] This gentleman was remarkable for the admirable manner in which he prepared caterpillars, so as scarcely to differ from life.
