A single male specimen in good condition from collection TJ. S. Na- 

 tional Museum, taken by Mr. Bruce, 



The s])ecies is quite peculiar by the dark transverse line of front, 

 which is not found in any of its allies. It is close to pedalis in type of 

 maculation but exclusive of the ground color, the lack of the distinct 

 orbicular and the dusky secondaries are quite sufficient to distinguish 

 it. The tarsi are not annulate. 



Carneades pedalis sp. nov. 



General color of head, thorax, and primaries a fine reddish yellow, 

 or topaz. Head and thorax Immaculate. Primaries, basal line gemi- 

 nate, slightly paler, the outer defining line interrupted, blackish, pow- 

 dery ; t. a. line geminate, paler, very even and almost upright; marked 

 on costa by two black spots, from the inner of which extends a black 

 powdering relieving the line. T. p. line geminate, paler, marked cos- 

 tally by black spots, from the outer of which extends a curved black 

 line reduced to a powdering below the cell; the inner line is defined 

 only by the pale included shade and is crenulate ; the general course is 

 very even below the costal outcurv^e. Through the center of the wing 

 is a rather broad, black, slightly irregular median shade line, which is 

 the most prominent feature of the wing maculation. Beyond the t. p. 

 line the s. t. space becomes powdery, darkening to black outwardly, 

 and relieving the concolorous s. t. line, which is rather irregular and 

 very distinct, except near anal angle, where the black shade is pow- 

 dery. A row of narrow terminal lunules. Orbicular small, round, pale 

 ringed, with concolorous center. Reniform moderate in size, normal in 

 form, with an indistinct pale outline filled with black powderings. 

 Claviform wanting. Secondaries pure white. Beneath white, j^rimaries 

 with a slight reddish suffusion, the dark reniform reproduced; second- 

 aries immaculate. Tarsi annulate with black.
