The EUCHARIS-Grovp 



Externally similar in colour and wing-pattern to species in the tullia and 

 tomtom-groups. 



Characterized in the male genitalia by the bilobate, often asymmetrical uncus 

 and by the broad, deep ventral plate of the gnathus, sometimes asymmetrical 

 in form. The valves are either symmetrical or asymmetrical. The fulcrum 

 arises just basad of one-half of the aedeagus. 



Characterized in the female genitalia by the very strongly sclerotized cone-like 

 sterigma, often with a tapered projection from the posterior margin, enclosing 

 the operculum and ductus bursae. 



Key to Species 

 Less than one-half of each wing hyaline 



opala (p. 265) 



- More than two-thirds of each wing hyaline ...... 2 



2 (1) Hyaline area of wings pearl-coloured ..... eryma (p. 259) 



- Hyaline area of wings tinged with yellow or green ..... 3 



3 (2) Uncus symmetrical .......... 4 



- Uncus asymmetrical .......... 5 



4 (3) Shallowest depth of ventral plate of gnathus (measured from apical to basal 



margins) equal to or greater than greatest width of aedeagus (Text-fig. 439). 

 Ventral and dorsal margins of valve almost parallel . . eucharis (p. 260) 



Shallowest depth of ventral plate of gnathus equal to one-half greatest width 

 of aedeagus (Text-fig. 441). Dorsal margin of valve sinuous, apical fourth of 

 valve narrowed to one-fifth of width of base . . . volsella (p. 262) 



5 (3) Right valve slenderly produced to acicular apex, incurved towards uncus 



(Text-fig. 443) . . ' . . . . . deformata (p. 262) 



- Valve not so formed .......... 6 



6 (5) Ventral and dorsal margins of right valve produced in acicular form. Right 



lobe of uncus twice as broad as left lobe (Text-fig. 445) . mimesis (p. 263) 



- Ventral margin of right valve irregularly and diagonally inclined to tapered 



apex of dorsal margin. Left lobe of uncus produced to acicular apex; 



right lobe atrophied ........ variola (p. 264)

J $ (PI. 122, fig. 1095). Hyaline area of wings pearl-coloured, sparsely irrorate with grey 

 along posterior margins and finely edged distally with brown; discal spot on fore wing dark 

 brown, sometimes grey at centre, that on hind wing minute and brown, when present. 

 Non-hyaline terminal area light brown (pi. 7, D4) to greyish brown (pi. 7, E3) proximad of the 

 darker, heavily marked, brownish grey (pi. 7, F2), dentate subterminal fascia, which is finely 

 edged distally with glossy buff; distad of the fascia the wing is light brown to greyish brown 

 irrorate with brownish grey. Underside of non-hyaline terminal area uniformly brownish 

 grey. 



The male hind tibia is dilate with a longitudinal fold one-half as long as the tibia and a
