In the treatment below, the species belonging to each of the genera 

 are neither described nor discussed, but are merely assigned to their 

 proper place. Subspecies are not listed at all in this paper. Com- 

 plete specific accounts will be offered at a later date by both the 

 present writer and by Prof. Jos6 Herrera-G. of the University of Chile. 



Key to the genera and subgenera treated in this paper 



1. Tibial spurs present on mid and hind legs 2 



Tibial spurs absent on mid and hind legs 3 



2. Male with uncus distinctly shorter than its greatest width (dorsal or ventral 



view) (fig. 9) ; female with inner genital plate having a finger-like process 

 that is nearly parallel to the anterior lobe (fig. 34) ; claw short and thick, 

 only slightly more than twice as long as its width at base (fig. 25). 



Thcochila (p. 106) 



Male with uncus at least as long as its greatest width (dorsal or ventral 



1 view) (fig. 10); female with inner genital plate having a finger-like process 



that is not parallel to anterior lobe (fig. 35) ; claw nearly three times aa 



long as its width at base (fig. 26) Tatochila (p. 108) 



3. Forewing with four radial veins 4 



Forewing with two or three radial veins 5 



4. Forewing with vein M^ from apex of cell or from very near apex of cell (con- 



nate or nearly connate with base of Rj-f R4+i+Mi) (fig. 19). 



Hypsochila (p. 110) 

 Forewing with Mj from distinctly below apex of cell (fig. 23) (see third 



choice) Piercolias (Picrcolias) (p. 118) 



Forewing with Mj stalked with base of Rs-f R^+s-f Mi (fig. 24). 



Baltia (p. 118) 



5. Hindwing with Cu2 arising from near middle of cell and about opposite orij:in 



of R, (figs. 20, 21); with distance between bases of Cui and Cuj on the 

 hindwing equal to the distance between bases of R, and Mi (figs. 20, 



21) 6 



Hindwing with Cu2 arising from distinctly beyond middle of cell and not at 

 all opposite origin of R» (fig. 22) ; with distance between bases of Cui and 

 Cu2 on the hindwing less than the distance between the bases of R, and Mi 

 (fig. 22) Piercolias (Pierphulia) (p. 117) 



6. Forewing with Ri from less than two-thirds to about one-half the length of 



R2 (fig. 20); hind leg with femur shorter than tibia; harpe acuminate 



(fig. 4) Phulia (PhuIiaXp. 114) 



Forewing with Rj nearly the same length as R2 or only slightly shorter (fig. 

 21); hind leg with femur about same length as tibia; harpe blunt (fig. 5). 



Phulia (Infraphulia) (p. 114) 



Theochila, new genus 



f Type: Pieris maenacte BoisduYa\= Theochila maenade (Boisduval), 

 new combination. 



Theochila dilFcrs from the other genera chiefly in the aedeagus, 

 anellus, and uncus of the male genitalia and in the inner genital 

 plate of the female. In addition it differs from most species of 

 Tatochila m the position of vein Cua of the hindwing and from all of
