insect more nearly resembles Epargyreiis exadeus Cramer, of which 

 it may be regarded as an extreme insular variety, though so far 

 removed from the parent stock as to merit recognition as a species. 

 The specimens were all taken at Nueva Gerona, and the dates of 

 capture range from the end of July to the beginning of September.

There are two specimens of this species taken at Nueva Gerona on 

 July 30 and August 10.

 Cuba, VII, 1856, p. 269. 



In this insular form of P. idas the transparent spots of the wings 

 have become almost entirely obliterated or reduced to microscopic 

 points, except the minute spots on the costa of the primaries. Only 

 one of the great suite of specimens before me retains the spots on the 

 disk of the fore wings though somewhat reduced and thus corresponds 

 with the form described as P. angasi by Godman, a specimen of which 

 from St. Vincent donated by Mr. Godman to the Carnegie Museum 

 is before me as I write. The Cuban form, like P. angasi Godman, 

 has the white markings of the under side of the secondaries greatly 

 obscured and more or less suffused with "chocolate red," as pointed 

 out by Godman. 



Mr. Link took eighty-one specimens of this insect at Nueva Gerona 

 from the last week in July to the last week in August.

This widely distributed insect is represented in the collection by 

 seventeen specimens, male and female, a few taken in May, and the 

 rest from the last of July to the end of August. The}' belong,
