56 STUDIES IN AUSTRALIAN LBPIDOPTBRA 



Xyleutis EREMONOMA. 



Xyleutis eremonomn, Turn., Tr. R.S.S.A., 1906, p. 139. 



Q., Cunnamulla. N.S.W., Brewarrina ; one ^ 

 example received from Mr. W. W. Froggatt, who slates 

 that the larvae feed in the roots of the " Roley Foley," 

 the plants snapping off and blowing away through their 

 infestation. 



Fam. HEPIALIDiE. 

 Hepialus astathes, n. sp. 

 daraOrjg, unstable. 



(J 41-44 mm. Head whitish sometimes pinkish. 

 Palpi fuscous, internal surface whitish. Antennae very 

 short, ochreous-whitish. Thorax with a posterior cresl ; 

 whitish, sometimes pinkish ; an ill-defined transverse 

 median greenish band. Abdomen whitish, towards apex 

 greenish or pinkish. Legs ochreous-whitish or pinkish. 

 Forewings triangular, costa strongly sinuate, apex acute, 

 teimen sinuate, oblique ; pale green, or pinkish with or 

 without greenish suffusion, some irregular darker striae ; 

 a whitish streak on basal | of costa ; a slender whitish 

 streak from mid-disc at | towards but not reaching dorsum 

 beyond middle, then curved and continued parallel to 

 termen to f costa ; cilia whitish. Hind wings with termen 

 sinuate ; white ; tinged with greenish or pinkish at tornus ; 

 cilia whitish. 



$ 46-72 mm. Forewings fuscous-reddish ; a large 

 triangular green blotch beneath costa from ^ to f, its 

 rounded lower angle approximating to mid-dorsum ; a 

 broad green terminal band not reaching tornus, sometimes 

 with a projection on its anterior border in mid-disc ; cilia 

 fuscous -reddish. Hind wings with termen sinuate ; pale 

 red ; some fuscous suffusion at tornus ; cilia reddish. 



Allied to H. lignivorus ; the females of the two species 

 are hardly distinguishable. The males are very distinct 

 in the discal curved line, which in astathes is more like 

 that of lewinii. The colouration of the J" varies much.
