Piercolias differs from all the other genera in the uncus, in the female 

 genitalia, and in habitus. From Phub'a it differs also in the position 

 of Cu2 in hindwing. From Tatochila and Theochila it differs in lacking 

 tibial spurs on mid and hind legs and in the form of the claw. 



Venation: Figures 22, 23. Forewing with three radial veins, 

 R4_j.5 having anastomosed with R3, or with four radial veins, R5 having 

 anastomosed with R4; Ri long, nearly same length as R2 or only slightly 

 shorter; M2 from below apex of cell or stalked with base of Rs+i+s+Mi; 

 R2 from apex or from very near apex of cell. Hindwing with Cu2 

 from distinctly beyond middle of cell and not at all opposite origin of 

 Rg and with distance between bases of veins Sc+Ri and R, distinctly 

 greater than distance between Cu2 and M3; distance between veins 

 Cui and Cu2 distinctly less than distance between bases of Rg and Mi. 



Legs: Spurs lacking on mid and hind tibiae. Paronychium (figs, 

 30, 31) as described for the two included subgenera. Claw (figs. 30, 

 31) relatively long, at least three times as long as width at base and 

 with its dorsal margin gradually curved. Tooth from near middle of 

 claw and with its dorsal margin about equal to or longer than width 

 of claw at base. Pulvillus (figs. 30, 31) narrow and greatly reduced, 

 being from less than one-half to one-half width of claw at base. 



Genitalia: Male (figs. 6, 7, 14, 15) with uncus very slender, 

 much more so than in Tatochila and Phulia, and gradually produced 

 into a finger-like process that is neither constricted near the middle 

 (in lateral view) nor swollen behind tip; lateroventral walls at base of 

 uncus neither infolded nor possessing internal ridges; subscaphium 

 present, although sometimes poorly developed ; harpe either acuminate 

 or broadly produced apically; anellus as in Phulia, Hypsochila, and 

 Tatochila, lacking dorsal plate; aedeagus not different from Phulia, 

 Hypsochila, and group E of Tatochila. [The five groups of Tatochila 

 are defined in another paper, in press.] 



Female (figs. 39, 40) with ductus bursae shorter than bursa copu- 

 latrix (without the accessory pouch), colorless and nonsclerotized and 

 with other characters as described for the two included subgenera. 



Habitus: Hindwing and apex of forewing below with a white to 

 cream or pink ground color, entirely and heavily irrorated with black 

 scales giving a gray or pinkish gray appearance. Hindwing without 

 long brown, gray, or black bars and stripes but usually with a sub- 

 mesial series of dark spots. 



Piercolias is here divided into two subgenera. First, the subgenus 

 Piercolias for the species traditionally placed in the genus by that 

 name, and second, for two species usually placed in Phulia. The 

 latter are included with Piercolias because they have essentially the 

 same type of uncus, vein Cu2 on the hindwing has the same point of
