(??. Structarally almost the same as pistacina. Body and wings greyish 

 olivaeeons 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 off externally, second 

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

 obviously joining the postdiscal cloud between R' and It', 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 often green, in which case the black submarginal band is reduced. 

 The oblique apical line of forewing, below, forms an angle behin<l ]{- with the 

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

 broad as in schausi. 



(?. Genital armature not apparently different from that oi pistacina, except 

 that the harpe is rather stouter, less curved, and dentate at end, and the jiroximal 

 edge of the left process of tlie penis-sheath more regi^larly and strongly dentate. 



Early stages not known.

 Southern Brazil.

 Mexico, iii. iv. (Schans) : Aroa, Venezuela. 



A small 3 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 obliqne ; the 

 tenth abdominal sternite is also narrower and is pointed.
