374 REVISION OF AUSTRALIAN LEPIDOPTEBA, 



from areole, 10 separate from areole. Hindwings with 3 and 4 short-stalked, 5 

 from middle or slightly below middle of cell, 6 and 7 long-stalked, 12 approxi- 

 mated to cell nearly to its end, hut not connected. 



There is only one species, which is narrower-winged than usual in this sub- 

 family. It is the only Australian genus in which the antennae are simple in the 

 2. In one c? 6 and 7 of hindwings are coincident on both sides. The large are- 

 ole is a primitive character. 



23. Oexosanda boisduvalii.

Subfam. NOTODONTINAE. 



I'ongue strongly developed, weak, or obsolete. Labial palpi always present. 

 Antennae of c? usually bipectiuate, of 2 usually simple. Forewings with or 

 without areole. Hindwings with vein 5 rather weak, rarely absent, 12 usually 

 approximated to cell to near its end, always to middle, rarely connected or 

 anastomosing. 



Having already treated most of the species at some length (Proc. Linn. Soc. 

 N.S.W., 1903, p. 42) I can dispose of them here more briefly. The group is of 

 moderately large size and is present in all continental areas, but is most largely 

 developed in South America. The species derived from the old "Austral" fauna 

 are few, comprised in the genera llyleora, Neola, Sorama, Destolmja, Ecnomodes, 

 Antimima, Danima, Discophlehia and Gallaba. Probably all the remaining genera 

 . are Oriental immigrants. None of the genera are of large size, and they are 

 rather closely connected, so that it is difficult to construct a satisfactory key.
