This species much resembles X. viridescens, but may be dis- 

 tinguished by the head, which is green, not white, by the number 

 and direction of the bands of the fore wings, by the red exterior 

 border, and by the hind wings, which are wholly white, whereas in 

 X. viridescens they are testaceous along the interior border and 

 pale brown along the exterior one. Length of the body 6 lines ; of 

 he wings 14 lines.
