Male. Upper surface sulpliur yellow, a narrow black line at the apex of 

 the primaries. 



Underneath the secondaries and apical portion of the primaries vivid orange 

 ochreous ; posterior portion of the primaries as above. On the hind wings 

 there are two grayish black spots on the costa, and another below the cell at 

 the exsertion of the first median veiulet. Wings shaped as in Pi. Margarita ;

Bab. " Mexico, (near Vera Cruz)." Win,. H. Edwards. 



Allied to Pi. isandra, Boisd. 



38. Fieris pasion, nov. sp. 



Upper surface chalky-white, immaculate. 



Under surface : fore wings' apical area and hind wings suffused with pale 

 creamy ochraceous, otherwise as above ; upon the secondaries are four narrow 

 transverse greenish-gray lines ; two respectively running from the upper 

 thirds of the first and second subcostal veinlets to the costa ; the third starts 

 at the upper fourth of the submedian vein, bounds the lower portion of the 

 cell, is discontinued in the lower, and reappears in the upper disco-cellular 

 interspace ; the fourth, between the last and the margin, is composed of two 

 connected segments, rarely with a part of a third, all being contained within 

 the median interspaces ; the nervules here and upon the apex of the prima- 

 ries are outlined in the same color ; expanse 2 - 25 2-40 inches. 



Hah. "Mexico, (near Vera Cruz. ") Wm. H. Edwards. 



The ornamentation of the under side approaches very nearly to some spe- 

 cies of Hesperocharis. 



39. Synchloe ardema, nov. sp. 



Female. Upper surface black ; fore wings with a waved row of seven spots 

 across the apical half of the wing, an abbreviated row of four white spots 

 within these, running down from the costa, and an isolated spot, opposite the 

 fifth of the first row, between it and the outer margin, all wi.ite ; two pale 

 luteous spots in the middle and lower median interspaces. Hind wings black, 

 rarely with an indistinct orange brown shade across the disc ; fringe black, 

 spotted with white. 



Underneath: fore wings the same, with the enlargement of the white spots, 

 the addiiion of two submarginal lunes, of two spots within the cell, and of an 

 orange tawny streak at the base of the costa. Hind wings with a sub-basal 

 band of four spots ; a narrow mesial band extending from the costa to the sub- 

 median vein, and a marginal series of lunes, all ochreous ; intermediate be- 

 tween these last a series of six rounded white spots ; a tawny orange spot near 

 the anal angle ; expanse 1*87 inches. 



Body and antennae black, the latter annulated with white ; palpi streaked 

 with whitish ; legs tawny orange. 



Hab. "Mexico, (near Vera Cruz)." Wm. H. Edwards. 



I regard both this and the S. tellias, of Bates, as local modifications of S. 

 lacinia, Hiibner. 



40. Neoxympha xicaque, nov. sp. 



Upper surface pale brown ; fore wings with a broad dark brown terminal 

 border ; two narrow transverse waved and angulated lines, one extending 

 across the wing just beyond the cell, the other contained within the cell ; in 

 the upper portion of the area, enclosed between the first and the marginal band, 

 there are two rounded black spots, of which the anterior is the largest. 



Hind wings with two mesial, strongly angulated red-brown lines, of which 

 the portion of the upper one nearest the abdominal margin is usually obsolete : 

 following these is a series of six rounded black spots, of which the first and 

 third are the least, and the second is sometimes prolonged posteriorly, the 

 sixth is usually wanting ; the margin presents three continuous red-brown
