and 63 brown larvae, whilst only 28 were more or less transitional 

 . . . . Immediately before pupation all the larvae, both 

 •green and brown, acquire a lilac coloration. The fifth stage 

 lasts seven days, and the whole larval development 23 days, 

 the period from the deposition of the egg to the 

 appearance of the moth being only 31 days. . . . This 

 polymorphism is not in any way connected with a more advanced 

 development of the markings, since the larva of 6". stellatarum 

 shows, in this respect, a very low state of development. This 

 species displays only two stages: (1) Complete absence of all 

 markings. (2) A simple subdorsal with dorsal and spiracular lines. 

 We must, therefore, admit that the phyletic development of the 

 markings has for a long time remained at a standstill, or, what 

 expresses the same thing, that the marking which the adult larva 

 now possesses is extremely old (Weismann, Studies in Theory 

 of Descent, transl, pp. 246-252). 



[Page 14.] Variation of pupa of Sesia stellatarum. — The 

 pupa varies but very slightly ; the ochreous-yellow ground colour 

 sometimes passes into reddish, and sometimes into greenish ; the 

 rather complicated blackish-brown marking of streaky lines is very 

 constant, especially on the wing-portions, being at most only more 

 or less strongly pronounced. The minute colour variations of the 

 pupa, therefore, have no connection with the colour of the caterpillar, 

 both green and brown larvae furnishing sometimes reddish-yellow 

 and sometimes greenish-yellow pupae (loc. cit., pp. 252-253).

 [Page 49.] Turneria hybr. Amelia, Feisth., "Bull, des Sci. Nat.." xi., 

 pp. 162-163(1827); Roths. & J'mcI., " Revis. of Sphing.," p. 729 (1903).— At first 

 sight, Sphinx amelia resembles a faded example of hippophaes, but one finds on closer 

 study that the general appearance is rather that of vespertilio, in fact, it seems 

 to be a hybrid between these two species, but an examination of the larva leaves 

 no doubt that it is a distinct species. The size is that of an ordinary hippophaes, 

 and the shape of the wings is the same ; above, the forewings are of a pale grey 

 with the posterior bolder darker and ornamented with a band the whole length 

 of the wing ; the band widens from the apex almost to the middle and the 

 extremity of the lower edge. The margin is edged with yellowish-white but 

 becomes tinged with slaty-blue as it approaches the body. There is no black 

 spot in the middle of the wing as in hippophaes, but an indistinct mark. The 

 hindwings are rosy between two black bands, nearly equal in width. The rosy 

 band is much wider than in hippophaes; the black posterior band is furnished 

 with a narrow yellowish-white edge; there is, as in hippophaes. an oibicular space 

 near the body, between the two black bands, but instead of being white it is rosy. 

 On the underside the forewings are of an ashy-rose, slightly tinged with bluish 

 at the extremity ; one notes on the underside, as on the upperside, the same 

 absence of the little black line which is found in hippophaes. The body is of a 

 bluish-grey, with the sides of the anterior half of the abdomen white, and cut 

 transversely by two small black bands. The legs are of a yellowish-white, 

 the inner part nearest the body is furnished with bluish scales. The trunk 

 is similar to that of hippophaes, i.e., a shiny yellowish-brown. The antennae are 

 whitish above and greyish below. Lawa : When the larva attains its full growth 

 it measures 2|ins. in length ; it is of a dark green-brown and furnished with sienna- 

 coloured points, ranged along the body segments. The head is golden-yellow, 

 having a wide cross of the same colour on the 1st segment. The stigmata are 

 rosy and decrease in size from the anus to the head so that the 5th is scarcely 

 visible. The venter is of a j ale lilac, bordered with a rosy-white line which 

 separates in all its length the general colour of the upperside of the body from that 

 of the venter. The prolegs and true legs are of a beautiful rose colour, the latter 

 are a little the darker. The anal horn of this larva is shorter, lightly marked, 

 of a brown-green above and rose on the sides. It is to be observed that this
