ing also the row of three light-colored interspacial dashes at 

 about the middle of the internal margin. The veins in Cra- 

 mer's figure are more broadly striped with dirty reddish on 

 the upper surface of the primaries, and the terminal band is 

 only indicated from the disco-central to medio-central inter- 

 spaces, where it is not broadly waved as in C. mexicana. The 

 very different male figured by Cramer is not what we should 

 expect, as the opposite sex of the present species, which con- 

 forms in its habitus to C. regalis, and which we seem author- 

 ized to regard as representative of the latter in a more south- 

 ern latitude. In Cramer's figure of the $ Phal. Zaoccon, the 

 terminal band is completely given, but, as in the female, quite 

 narrowly ; thus opposed to its development in C. mexicana, in 

 which it is broad and prominent. The resemblance between 

 C. regalis and C. mexicana consists rather in the abstract pat- 

 tern of ornamentation proper to the genus, than in purely 

 specific characters. Thus, while we select C. regalis, or what 

 is much better, C. mexicana, as exhibiting the fullest develop- 

 ment of its generic pattern of ornamentation, we have in C. 

 sepulcralis, its most degradational aspect, and, having com- 

 pared the species structurally as generically identical, we can 

 agree upon the distinctive pattern of ornamentation which 

 predicates the association of the species. We regard C. mexi- 

 cana as replacing C. regalis in the entomological fauna of the 

 Tropical Continental District.
