160 RKVISION OF AUSTRALIAN TOKTHICINA, 



29. H. exceca, n.sp. 



(J^. 12-13 mm. Head and thorax white. Palpi white, tinged 

 externally with ochreous. Abdomen whitish. Forewings 

 elongate, posteriorly, dilated, costa gently arched, apex obtuse, 

 termen obliquely rounded; white, ]>artially tinged with pale 

 oclireous-yellowisli; l>asal fifth of costa suffused with ochreous; a 

 more or less developed outwardly oblique ochreous streak from 

 dorsum near ba.se. reaching half across wing; a deep ochreous 

 narrow fascia slightly beyond middle parallel to termen, tending 

 to be" obsolete at extremities, posteriorly edged with a few black 

 specks; an irregular narrow ochreous fascia just before termen 

 from apex to tornus, anteriorly edged with a few black specks; 

 between this and preceding fascia is sometimes more or less 

 irregular pale yellow-ochreous suffusion : cilia white, partially 

 tinged with yellow-ochreous, with a few black specks, especially 

 at tornus. Hindwings and cilia whitish. 



New Guinea: Sudest I. (Meek) — Q.: Townsville, in May(Dodd); 

 three specimens. The smallest, relatively shortest-winged, and 

 least decorative species. 



8. Hypkrxena Meyr. 

 Hyperxena Meyr., Proc. Linn. Soc. N. S. Wales, 1882, 



177 ... .^ ... ... ... ... type sci'?ra?ia. 



Palpi very long, porrected, second joint with long rough 

 obliquely projecting scales above, terminal long, rough-.scaled 

 above. Thorax with double posterior crest. Forewings with 

 tufts of scales, 7 to costa, 8 separate. Hindwings with 3 and 4 

 remote, parallel, 5 nearly parallel, 6 to costa, 6 and 7 remote, 

 nearly parallel. 



The single species, of which the ^ is still unknown, is super- 

 ficially dissimilar to the rest of the family, and its structural 

 characters are so far unspecialised as to leave its affinity some- 

 what uncertain; but after a very careful consideration of the twa 

 original specimens, which are all I have seen, I can see nO' 

 grounds for referring them elsewhere, and think they may be a 

 primitive type of this group.
