green, shining; a deep purple-violet apical patch, its size and shape vari- 
able: its inner edge mostly from middle of costa to tornus, but in one 
female from before 1 / 3 of costa to termen along vein 3, concave, mostly 
slightly sinuate, sometimes convex above middle and concave at extre- 
mities, seldom produced into a short streak along costa. Cilia deep indigo- 
blue, shining. Hind wing deep orange, with a deep purple-violet apical 
patch, which is mostly elongate-ovate, covering posterior 2 / s of costa and 
reaching somewhat below vein 5, in one female specimen crcct-ovate, 
covering not more than posterior '/ 4 of costa, but reaching downward to 
vein 4. Cilia deep indigo-blue around apical patch, deep orange elsewhere. 
Under side: base of fore wing suffused with deep metallic-green, base of 
hind wing suffused with brown. 
Tegumen very strong, clavate. Uncus very broad, top bifid. Gnathos 
strong, with an angulate median dilatation and a long clavate hook. 
Socius, a rounded patch of bristles. Transtilla knob elongate, with two 
ridges of dentations, median projections broad at base, almost touching 
each other in middle. Peniculus short, rather weak, rounded, sparsely 
bristled. Juxta broad, flattened. Vinculum broad, rounded. Valva short. 
Aedoeagus robust. (Slide No. 307 D.) 
Limen narrow, rectangular. Colliculum small, weak. Cestum broad, 
coiled above, with regular torsions beyond coil, corrugated at the same 
time. Distal fold strongly sclerotized. Signum narrowed towards point. 
Ovipositor lobes broad. (Slide No. 319 D.)
