example. There are three appendages, an upper and two lower ones. 
He calls the former the tegumen, and the latter the harpagones, though 
possibly equivalent to the appendices inferiores in Trichoptera. A brief 
abstract is given in J. L. S. xiii. p. 195, and the paper will be noticed 
again when published in its complete form. 
A paper by the late D. Biirger on the nervous system of Lepidoptera 
is published by 0. A. Holfmann in Niederl. Arch. Zool. iii. pp. 97-125, 
pi. vi. He concludes that the chorda supra-spinalis in Lepidoptera is 
directly connected with the external neurileum of the abdominal cord 
(Bauchraark), of which it is an outgrowth. 
Various observations on the senses of Lepidoptera^ their stridulation, 
and on the fertilization of flowers by them, may be found in Nature, xv.

Trouvelot and Packard describe various experiments on the antennae 
and other senses of Lepidoptera, &c., but without being able to form any 
definite conclusion as to the functions of the antennae. Am. Nat. xi. 
pp. 193-196, 418-423. They also state (I. c. p. 243) that white and yellow 
butterflies prefer flowers of their own colour.

toed sloth ; and on the pupa of a Tachina. Cf. also P. E. Soc. 1877,
