Hypsochila Ureta 



Hypsochila Ureta, Bol. Mus. Nac. Hist. Nat., vol. 26, p. 58, 1955. 



Type: Tatochila microdice j. wagenknechti VTetSi= Hypsochila 

 wagenknechti (Ureta). Type by original designation. 



This genus differs from Tatochila, its nearest relative, and from 

 the other genera in the shape of the claws. From Tatochila and 

 Theochila it differs in lacking tibial spurs on mid and hind tibiae and 

 in the position of vein M2 on forewing as well as in habitus. From 

 Phvlia and Piercolias (Pierphulia) it differs also in having propor- 

 tionately broader wings and in having four radial veins present on 

 the forewing. It differs from all of the other genera in having the 

 silvery sheen on forewing extending over a much larger area. 



Venation: Figure 19. Similar to that of Tatochila and Theochila, 

 differing in having M2 of forewing from apex of cell or from very near 

 apex of cell. Forewing with four radial veins, Rs having anastomosed 

 with R^; Rj more than one-half but not more than two-thirds the 

 length of R2; R2 from distinctly before apex of cell. Hindwing with 

 Cu2 from near middle of cell and about opposite to origin of R,; 

 distance between bases of veins Sc-f-Ri and Rg about equal to the 

 distance between Cu^ and M3; distance between Cui and Cu2 about 

 equal to the distance between the bases of Rg and Mj. 



Legs: Spurs lacking on all three tibiae. Paronychium (fig. 27) 

 at least two-thirds as long as claw, rather narrow, tapering and slightly 

 constricted near middle and with its width at base about one-fifth 

 its length. Claw (fig. 27) directed outward with its dorsal margin 

 gradually curved and its long axis divergent from basal margin; 

 relatively long, at least three times as long as width at base. Tooth 

 divergent from distal portion of claw, originating from near the middle 

 and very small, having its dorsal margin less than width of claw 

 at base. Pulvillus (fig. 27) narrow, about one-half as broad as base 

 of claw. 



Genitalia: Male (figs. 3, 11) with uncus, harpe, and anellus not 

 different from that of Tatochila; subscaphium absent or only very 

 faintly indicated; aedeagus in lateral view about as broad distally
