Godart's specific name has priority over the name margarita 

 applied by Hiibner. 



There are thirteen males and four females in the collection. The 

 males have the dark apical markings reduced to a fine black marginal 

 line. The specimens were taken at Xueva Gerona from the end of 

 June to the latter part of August, 1912. 



Genus Pieris Schrank. 



26. Pieris monuste (Linnaeus). 



Papilio monuste Linn^us, Mus. Lud. Ulr., 1764, p. 237. 



Of this common neotropical species the collection contains eleven 

 males and five females. The latter vary greatly in the breadth and 

 intensity of the dark markings of the wings. One female has the 

 wings marked almost exactly as the males. The specimens were all 

 taken at Nueva Gerona, and the dates of capture run from May 9 

 to August 22, 1912. 



Genus Catopsilia Hiibner. 



27. Catopsilia eubule (Linnaeus). 



Papilio eubule Linnaeus, Syst. Nat. (10), I, 2, 1767, p. 764. 



Of this excessively common insect there is a large series of males 

 and females, taken from May until October, 1912, mostly at Nueva 

 Gerona. The form of the female which has been named C. sennce 

 is as numerous as the less strongly marked female which conforms 

 more nearly to the pattern of maculation found in the males. 



It may be remarked at this point that the great variation which 

 occurs in the females both in color and in the maculation of both sides 

 of the wings makes the correct determination of specific relationships 

 and differences in this genus very difificult. Until the test of breeding 

 shall have been thoroughK- applied we must remain in some doubt
