A BUTTERFLY OF :\1ELANIC FORM. 
By P. Franzex. 
Butterflies of a melanie form are by no means common, 
^uid when my son. some time back, had tlie good fortune to 
capture one, 1 was naturally very pleased. 
Arraea androniacha ; typical and melanie forms. 
(From a Photo, by H. Hacker.) 
The specimen here referred to belongs to the genus 
Acrnea. of which we have but one representative in Aus- 
tralia— namely. Acraca androtnaclia (Fab.). 
To he able more clearly to demonstrate the difference 
in tlm melatiic and typical form of this butterfly, I have 
witii this note supplied a photograph of each. 
From the photos it will be seen that the melanie form 
is entirely devoid of typical markings, wTiich gives the 
bnttertiy a very black appearance when compared with an 
ordinary specimen. 
Forewings — Semitransparent; each wing with six 
black opaque stripes parallel to the veins and 
extending more than half across diseal area. 
Hindwings — Entirely black; opaque; with an 
obscure light mark on dorsum. 
SPECIAL ACKNOWLEDGMENT.
