representative of the original condition of vvijig-marking, or has it 

 in its turn arisen by raoditication from a still more primitive pattern,

in which the transverse rows of spots were still more numerous. 

 The abovementioned traces of an originally higher number of spots 

 in Uthetheisa pulchella already points in this direction, but the 

 supposition is especially supported by a comparison with the Hepi- 

 alids, in which the number of rows, composing the dumbbell- or 

 hourglass-pattern, which I consider as the primitive design, is nearly 

 twice as large. 



Should my supposition prove right, then the colour design of 

 Arctiidae (as well as of numerous other Heterocera and probably 

 also Rhopalocera) should not be considered as a representative of 

 the primitive Lepidopterous pattern, but on the contrary as the 

 homologue of the secondary Hepialid design. The latter in its turn 

 has issued from the primitive one by higher differentiation of alter- 

 native rows of spots, e.g. of the rows 2, 4, 6, 8, 10, 12, 14, if, 

 for convenience sake, we infer for a moment, that the original 

 number really amounted to fourteen.
