Note 296 — LETTER XXX.

The claws or crotchets, though general, are not universal, in Lepidopterous larvæ. An exception is furnished to the rule by the singular limaciform ones of Hepialus Testudo and Asellus of Fabricius, two moths forming Haworth's genus Apoda, which have no distinct prolegs, but in their stead a number of small transparent shining tubercles without claws. The larva also of one of the subcutaneous moths first discovered by De Geer in the leaves of the rose (i. 446), but whose history is fully given by Goeze, Naturf. xv. 37-48, (who has satisfactorily ascertained that it is the true larva of a Tinea of Linné, but of a different habit from that of most subcutaneous ones), has no true legs, and eighteen prolegs without any claws. Another subcutaneous larva, for the history of which we are indebted to M. Godeheu de Riville, is according to him entirely deprived of legs of any kind (Bonnet ix. 196—.); as is another of the same tribe that feeds on the poplar, an account of which is given by Goeze Naturf. xiv. 105.
