red. Palpus nearly three times as long as diameter of eye ; 
white, the first and second joints shaded with red on outer 
side. Vertex white, occiput green, a slight red line between. 
Antenna thick, lamellate, the scaled surface white. Thorax 
and abdomen above green, brighter than on the wings. 
Fore wing with a light red, yellow-mixed costal area, 
broadening from base to beyond cell, where it reaches R?, 
then narrowing to a point at apex; the rest of the wing pale 
olivaceous, mostly translucent behind the cell and R? from 
base to postmedian line, otherwise darkened with slaty grey, 
only becoming pale ereen at extreme termen and on fringe ; 
lines dark grey, rather thick but only defined on the red costal 
pateh, where the postmedian is accompanied distally by some 
yellow spots ; a long-oval yellow spot near apex; an ill- 
defined oblique blackish dash from apex, deepest on fringe ; 
some ill-defined slaty-grey patches on hind margin in tie 
translucent area, the most prominent enclosing a pale space. 
Hind wing strongly angled at R’; C approximated to SC 
for a short distance near base, including anastomosis at a 
point only ; nearly all grey, the basal and distal areas more 
brownish, the median more slaty ; cell-mark and curved (near 
abdominal margin sinuate inward) postmedian line indicated 
in darker grey ; a green spot on abdominal margin proximal 
to median area and slighter green shades distally on the same 
margin ; distal margin very narrowly green ; fringe green. 
Underside paler greenish, similarly but more vaguely 
marked.

In spite of the great differences it is conceivable that this 
may bea 2 form of busa, Druce (Biol. Centr.-Amer., Lep. 
Het. i. p. 92), of which the unique type (from Chiriqui, 
Panama) is a @ in Coll. Staudinger and unknown to me. 
That there is sometimes strong sexual dimorphism in this 
genus is shown by latifusciata, Warr., and others, in which 
the 2 has complete and broad distal border to the tore wing, 
while that of the ¢ is broken.

(Pl. VII. fig. 14.). 
3 .—22 mm. 
Smaller and greener than the name-type, the white 
markings narrowed; particularly noticeable is the slender 
but almost uninterrupted postmedian line of the fore wing.
