Excepting in its usually slightly shorter wings, redder tint, and the pale subapical 

 border, I see nothing to separate this from the preceding species ; and as our female of 

 E. luguhris from Haiti is of a redder tint still, and has the wings as short as E. camer- 

 tus <S , whilst a female from St. Thomas has the wings even shorter than E. camertus 2 , 

 I have very little doubt that the two forms are variations of one species (see also "Wal- 

 lengren, CEf. Vet. Akad. 1871, p. 913) ; no doubt it would be easy to render it in ap- 

 pearance quite distinct were we to pick out all the small and pale females of E. luguhris 

 (as it seems to me that my friend Grote must have done 1 ) ; but as in our case the sexes 

 arrived together from Haiti, this would be impossible.

This is a well-marked species, at once recognized by the fusiform sulphur-yellow 

 patch on the abdominal margin of secondaries ; I believe this to be the Sph. ozypete of 

 Linnaeus.

Hiibner's E. luguhris is unquestionably the typical female of that species ; it has the 

 same scalloped outer margin, which, however, is wanting in this species. 



1 If I have done Mr. Grote an injustice in this supposition, I know he will forgive me ; but he mentions only 

 "three female specimens" in his comparative description.
