GeometriJse in the Joicey Collection, 125 



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 icing with a light red, yellow-mixed costal area, 

 broadening from base to beyond cell, where it reaches E,', 

 then narrowing to a point at apex; the rest of the wing pale 

 olivaceous, mostly translucent behind the cell and E,^ from 

 base to postmedian line, otherwise darkened with slaty grey, 

 only becoming pale green at extreme termen and on fringe; 

 lines dark grey, rather thick but only defined on the red costal 

 patch, 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-defiued slaty-grey patches on hind margin in tiie 

 translucent area, the most prominent enclosing a pale space. 



Hind wing strongly angled at E,^ ; 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-maik 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 tin's 

 may be a $ form of husa^ Druce (Biol. Centr.-Amer., Le{>. 

 Het. ii. p. 92), of which the unique type (from Cliiriqui, 

 Panama) is a ^ in Coll. Staudinger and unknown to me. 

 That there is sometimes strong sexual dimorphism in this 

 genus is shown by latifisciuta, Warr., and others, in which 

 the ? has complete and broad distal border to the fore wing, 

 while that of the ($ is broken.

 (PI. VII. fig. U.) 



c? . — 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.
