12. Epalxiphoka, Meyr. 



Thorax with a very large erect crest on each side of back, and a small 

 double crest behind. Antennae in male thinly ciliated. Palpi moderate, 

 straight, porrected, second joint with appressed scales. Forewings with 

 costa in male simple, apex falcate. Hindwings broader than forewings. 

 Forewings with 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings 

 with 8 veins, 3 and 4 from a point, 5 moderately approximated to 4 at base, 

 6 and 7 stalked. 



A very peculiar genus, remote from any other known to me ; it contains 

 only one species. 



28. Epalx. axenana, Meyr. 

 (Epalxiphora axenana, Meyr., Proc. Linn. Soc. N.S.W., 1881, 648.) 



Media, alis ant. ochreo-albidis, dilute rufo-nebulosis, fascia angusta 

 dentata antica, duabus aliis ad costam confluentibus, signo disci trirarni, 

 macula costaa triangulari, strigaque postica sinuata saturate runs ; post, 

 griseo-albidis. 



Male. — 26 mm. Head and thorax whitish-ochreous, mixed with ochreous 

 and dark fuscous. Forewings oblong, moderately broad, costa rather 

 strongly arched, dilated before middle, apex falcate, hindmargin obliquely 

 sinuate ; whitish-ochreous, irregularly mixed and clouded with brownish- 

 ochreous ; veins posteriorly slenderly dark fuscous ; markings ochreous- 

 fuscous, becoming darker reddish-fuscous on costa and inner margin ; outer 

 edge of basal patch represented by a slender irregular, twice deeply dentate, 

 fascia from i of costa to § of inner margin ; margins of central fascia repre- 

 sented by similar slender irregular fascia?, both starting together from § of 

 costa, separating immediately below costa, anterior one proceeding nearly 

 directly to inner margin beyond middle, posterior one sharply angulated
