Five specimens taken amongst luxuriant bush on the ascent 

 of Mount Wellington, Tasmania, at an elevation of about 3,000 

 feet. 



CONCH YLID^. 



Hyperxena, n. g. 



Thorax with a double erect posterior crest. Antennae in male 

 — ? Palpi very long, straight, porrected, second joint with long 

 rough obliquely projecting hairs above, terminal joint very loug, 

 roughly scaled above. Posterior tibiae fringed with short hairs 

 above. Forewings elongate, narrow, costa (in male probably 

 simple) strongly arched, apex acute, hindmargin very oblique ; 

 surface with raised scales. Hindwings elongate, as broad as 

 forewings, cilia long. Forewings with veins 7 and 8 separate, 

 7 running to costa, secondary cell indicated, vein 1 furcate at 

 base (?). Hindwings with 8 veins, 3 and 4 remote at origin, 

 parrallel, 5 nearly parallel to 4, 6 running to costa, 6 and 7 remote 

 at origin, nearly parallel. 



This interesting genus is nearly allied to Heliocosma, Meyr., 

 which previously stood alone; the curious venation is nearly 

 identical, the essential point of distinction being that vein 7 of 

 the forewings runs to the costa, a very unusual character among 

 the Tortricina which recurs in the remote genus Term, Tr., and 

 vein 6 of the hindwings also runs to the costa. The thoracic 

 crest, very oblique hindmargin of the forewings, and long cilia 

 are also notable characters.
