and females have been described as different species. Plotz even goes so far as to put 

 them in different genera— the males in Entheus, and the females in Phareas. 



The antenna? are long, slender, the club slender and curved into a crescent. Palpi 

 porrect, divergent, the third joint long and slender. Primaries short, the inner margin 

 longer than the outer, the middle portion of the costal margin straight, the cell about 

 two-thirds the length of the wing, the costal area wide, and the subcostal branches 

 well separated ; upper discocellular short, middle and lower discocellulars subequal in 

 a slightly oblique line to the axis of the wing ; third median segment very short, hardly 

 a sixth of the length of the second segment ; discocellulars of the secondaries very faint, 

 the radial just visible, second median branch from the end of the cell and twice 

 as long as the second subcostal branch, the anal angle very slightly projecting, 

 outer margin much rounded. Hind tibiae short, much swollen distally, and with 

 a single terminal pair of spurs; a long tuft of hair from the upper edge of the 

 proximal end. 



No costal fold in the male. Sexes widely different in coloration. 



The range of Entheus extends from Guatemala to South Brazil, two species occurring 

 within our limits.

Taking Clerck's and Cramer's figures as the best representatives of Papilio peleus 

 rather than their figures of Papilio talaus, which represent a female of a species of 

 this group, and about which there may be some doubt, we use E. peleus as the name 

 of this common species. Eegarding the female this difficulty arises, that little difference 

 exists between that sex of R peleus, E. gentius, E. lemna, and some others, the males 

 being very distinct, so that it is a matter of some difficulty to assign to each species its
