J'?. Strurtiinilly almost tho same as pistucina. Body ami wings greyisii 

 (ilivaceous green, often very bright ; underside of body whitish green. 



Wings, above. Forewing : three antemedian lines, the two distal ones close 



together; first discal line heavy, straight, gradually shading ofi externally, second 

 and third line not marked, line 4 distinct anteriorly tiiough weak, more or less 

 obviously joining the postdiscal cloud between R' and W, some very small vein-dots 

 forming a continuation of the line, oblique apical line short, often not reaching the 

 postdiscal cloud. The green band of the hindwing not reaching costal margin, the 

 distal margin also otten green, in which case the black submarginal band is reduced. 

 The oblicpie apical line of forewing. lielow, forms an angle behind W with the 

 irregularly undulate postdiscal line, the marginal area bordered by these lines as 

 broad as in sc/taits/. 



c?. Genital armature not apparently different from that of pisfacina, except 

 that the harpc is rather stonter, less curved, and dentate at end, and the proximal 

 edge of the left process of the penis-sheath more regr,!arly and strongly dentate. 



Early stages not known.

A small (? from Theresopolis in the British Museum is on the underside more 

 yellow and has no discal line, the apical line of the forewing is less oblique ; the 

 tenth abdominal sternite is also narrower and is pointed.

(^ ? . Basal ciliae of antennal segments of ? distinctly prolonged. External 

 spur of midtibia somewhat shorter than internal one. No lines on alidomen. 

 Forewing : antemedian lines vestigial, the two distal ones forming a l)and at ai)ex 

 of cell, angnlated at M' ; the two proximal discal lines more or less merged 

 together to a, band, the inner line often straight : third discal line very feebly 

 marked ; fourth rather more distinct, generally accentuated by vein-dots, lines 2 to 

 4 dentate ; line o from apex curved, continuous with a greenish olive patch R- — R ; 

 ground-colour variable, the wing being occasionally much greener than in ordinary 

 individuals. I'ale band of the hindwing much suifused with olive-brown. Brown 

 border of underside of forewing ])road, less angulate behind R- than in schatisi. 



o. Tenth tergite truncate-sinuate ; sternite rounded at end. Process of harpe 

 long, very slender, pointed, somewhat curved twice, as in sckausi. Penis-sheath : 

 right process short, pointed ; left one also short, dentate, less projecting than in 

 sc/iaiisi. 



Early stages not known.
