IV] NEW-WORLD MIMICS 49 



D. archippus (PI. XVI, fig. 8) is very similar to the 

 oriental D. plexippus (PI. IV, fig. 2), from which 

 perhaps its most notable difference lies in the extent 

 and arrangement of the white spots near the tip of 

 the fore wing. D. berenice is not unlike archippus in 

 its general colour scheme but is smaller and darker 

 (PI. XVI, fig. 9). 



We have already had occasion to mention the 

 common Nymphaline, Limenitis arthemis (PI. XVI, 

 fig. 4) which is found in Canada and the North- 

 eastern States. Widely spread over N. America is 

 a close ally of this species, L. archippus, which, though 

 so similar in structure and habits, is very different 

 in external appearance. As appears from PL XVI, 

 fig. 6, L. archippus is remarkably like the Danaid 

 which bears the same specific name. In the Southern 

 States L. archippus is replaced by a form slightly 

 different in details of pattern and distinctly darker, 

 L. fioridensis {=eros) (PI. XVI, fig. 7). In Florida 

 occiurs also the darker N. American Danaid, D. berenice, 

 to which the colour of L. fioridensis approximates 

 more than to D. archippus, and it is of interest 

 that although the last named is also found in this 

 locahty it is said to be much less abundant than 

 D. berenice. Nevertheless it appears to be true that 

 the range of L. fioridensis is much more extensive 

 than that of its model ; in other words, that there 

 are considerable regions where L. fioridensis and 

 D. archippus coexist, and from which L. archippus 

 and D. berenice are wanting.
