 iii, p. 325, t. 78, f. 11-13. Ampidoxa eorneofulva SUTER, Trans. N.

This species was referred by Hutton to Hyalina cellaria, but 

 Suter has identified it with specimens of a Calymna from Nerger 

 Range, South Island, IS". Z. 



G. ZEBRA Le Guillon, 1842. (See P. phlogophora, vol. I, p. 128.) 

 Hutton is doubtless correct in including as synonyms H. phloyo- 

 phora Pfr., 1849; H. flammigera Pfr., 1852; H. multilimbata H. 

 & J., 1854.
