species. This latter character is very conspicuous in the females. The 

 posterior spot on the disc of Drexelii always rests on the second trans- 

 verse line, while the corresponding mark in Ministra is placed between 

 the first and second line, or in the field of paler color enclosed by these 

 two lines. The tip of the abdomen, too, is usually darker in Drexelii 

 than in Ministra. It must, however, be admitted that it is difficult to 

 define their separate characters in words, but when a large number of 

 specimens are placed side by side, they are apparent to every observer. 

 In the pupa stage there is little difference, but the pupa of Drexelii 

 is always a little larger than that of Ministra, and the spines of the 

 cremaster are decidedlv longer.

The large and interesting Hesperid, Proteides Zestos, Hiibn.,* seems 

 to have been entirely overlooked by students of the North America 

 fauna until redescribed by Mr. Worthington under the name of Oberon. 

 It has, however, been in the possession of collectors, as from Florida, 

 for many years. I have in my collection a specimen from the collec- 

 tion of the late Dr. Asa Fitch, which is labelled " Florida, Sept. '53," 

 and the American Entomological Society possesses three specimens, 

 one of which was presented by the late James Ridings prior to 1870. 

 I have also received this form from Yucatan; Samana Bay, San Do- 

 mingo; Nassau, Bahama Islands; Matanzas, Cuba; and Sanford, 

 Florida. Mr. Worthington describes it irom Marco Island, Florida; 

 and HUbner, and Kirby following him, from Surinam. Strangely 

 enough Dr. Gundlach fails to mention this in his Catalogue of the 

 Diurnal Lepidoptera of the Island of Cuba (Papilio, Vol. I, p. iii, 

 18S1); nor does he mention anv s]:)ecies that he could ha\e confused 

 with it. 



Hiibner's description is sufficiently full to identify this species, and 

 his figures of it, as is usually the case with his figures, all that could be 



* I feel some doubt as to the propriety of accrediting this form to Hubner, as it is figured in the 

 4th hundred of the Zutrage, which was published by Carl (lever in 1S32, six years after Hubner's 

 death. The reference in Kirby's Catalogue is erroneous.
