The Origin of the Markings of Caterpillars. 253 



reddish-yellow and sometimes greenish-yellow 

 pupae. 



The comparison of M. Stellatarum with the 

 other known species of the genus, brings scarcely 

 any addition to our knowledge of the phyletic 

 development. Thus, the two European species of 

 which the caterpillars are known, viz. M. Fucifor- 

 mis and Bombyliformis^ show essentially the same 

 markings as Stellatarum, the chief element being 

 a well-developed subdorsal line. The Indian M. 

 Gilia, Herrich-Schaf., possesses also this line, 42 and, 

 togetherwith the East Indian M. Cory thus, Walk., 43 

 has oblique stripes in addition ; the stripes do not, 

 however, cross this line, but commence underneath 

 it, and probably originated at a later period than the 

 subdorsal line. Should this be the case, we must 

 regard M. Corythus as representing a later phyletic 

 stage. According to Duponchel's figures, in both 

 M. Fuciformis and Bombyliformis small oblique 

 stripes (red) occur near the spiracles, but these 

 have nothing to do with the oblique stripes of M. 

 Gilia just mentioned, as they run in a contrary 

 direction. Of the two European species, I have

 genus Hemaris. R.M.] 



42 [This species is figured also by Butler (loc. cit. PI. XC., 

 Fig. 9), who represents it with seven oblique green lines 

 between the spiracles and below the subdorsal line. R.M.]
