This species is described as follows, by Mr. Hewitson: 



" Upper side white, with the apex and outer margin brown. A sub- 

 apical spot and some minute spots near the outer margin white. Pos- 

 terior wing with the outer margin and spots at the end of nervules 

 brown. 



' ' Under side. Anterior wing as above. Posterior wing with a 

 large bifid spot at the base of the costal margin, a small spot at the 

 middle of the abdominal fold, and the outer margin, which is broad, 

 rufous-brown. 



" Expands 1.5-20 inch. Island of Taboga, Panama." 



Thanaos Juvenalis, Fabr. Three specimens. 



We place these specimens under this species with some hesitation. 

 Unfortunately they are not perfect examples, nor are they in sufficient 

 numbers to use for study in this most puzzling genus. 



Thanaos Tristis, Bosid. Moderately common. 



Nisoniades Funeralis, Lintn. 



The characters on which Mr. Lintner separates his Funeralis from 

 Tristis, viz. : the absence of the discal spot on the primaries, and the 

 presence of the clear white border on the secondaries, are seen to be 

 of no value when a series is under comparison. These specimens from 

 Texas show that intergrades are the rule, not the exception. 



Systasea Zampa, Edw. Moderately common. 



Pholisora Catullus, Cram. Common. 



^ Pholisora Hayhurstii, Edw. Moderately common. 



Spilothyrus Nessus, Edw. Moderately common. 



Achlyodes Thraso, Hiib. Common. 



Eudamus Pylades, Scud. 2 9 .

Eudamus Tityrus, Fabr. i $ . 



Eudamus Proteus, Linn. Moderately common. 



Eudamus Simplicius, Stoll. i specimen. 



Eudamus Albofasciatus, Hew. Moderately common. 



Mr. Hewitson, (Desc. 100 New Hesp. p. 31 describes this species as 

 follows : 



"Upper side dark brown. Anterior wing with eight transparent 

 spots; four forming a central band ' the lowest spot very minute), one 

 outside of these, and three in a band before the apex. Posterior wing 

 with a very long tail. 



" Under side. Anterior wing as above, except that it is gray near the 

 ape.x, and marked by a triangular dark brown spot. Posterior wing 

 dark brown, crossed obliquely by a central band of white; a submar- 

 ginal band of gray. 



" Expanse 2 inches. 



" Habitat. — Guatemala (Polochic Valley ." 



Three or four new species of Hesperidce were also taken; they will 

 he described in subsequent papers of a monographic nature.
