526 Appendix. 



red ; dorsal stripe variable in colour, and sometimes 

 only partially present or altogether absent. " At the 

 end of May most of the larvae found presented a different 

 appearance ; the black disappears more or less, and with 

 it many of the small white spots. In some cases the 

 black only remains as a ring round the larger white 

 spots ; the ground-colour therefore becomes yellowish- 

 green or yellow, varying very considerably." The larva 

 does not change colour previous to pupation. This 

 species, according to the outline figure given (loc. cit. t 

 PI. XXXIX., Fig. 9), appears to belong to the first of 

 Dr. Weismann's, groups, comprising D. Euphorbia, 

 D. Dahlii and D. Nicaa (see p. 199), and is therefore in 

 the seventh phyletic stage of development (p. 224). From 

 the recorded habits it seems most probable that the 

 colours and markings of this caterpillar are signals of 

 distastefulness. It is much to be regretted that Major 

 Roberts has not increased the value of his description of 

 this species by adding some observations or experiments 

 bearing on this point. Eusmerinthus Kindermanni, 

 Lederer, feeds on willow. " General colour green, 

 covered with minute white dots and seven long pale- 

 yellow oblique lateral bands. (The ground-colour is 

 the same as the willow-leaves pn which the larva feeds, 

 the yellow stripes the same as the leaf-stalks, and the 

 head and true legs like the younger branches)." As no 

 subdorsal line is mentioned or figured, this species must 

 be regarded as belonging to the third stage of phyletic 

 development (see p. 242). 



I have recently had an opportunity of inspecting a large 

 number of drawings of Sphinx-larvae in the possession 

 of Mr. F. Moore, and of those species not mentioned in 

 the previous portions ot this work the following may be 

 noticed : Ch&rocampa Tlteylia, Linn., like Ch. Leivisii 

 (note 13, p. 194), appears to be another form 

 connecting the second and third phyletic groups of
