Whether we have several small genera or one large sec- 

 tion is purely a matter of individual opinion, and unless 

 there is a distinctive generic peculiarity I prefer the larger 

 genera, as fully three-fifths of the species enumerated in this 

 paper are endemic. The most troublesome and least under- 

 stood group are Ttlicota and the allied genera, and progress 

 must necessarily be slow, as no satisfactory arrangement can 

 be maintained until an exhaustive examination is accom- 

 plished by the accumulation and dissection of a large quan- 

 tity of material from the Indo-Malayan region. The 

 geographical range which I consider Australian is the con- 

 tinent proper and Tasmania. In the near future I intend 

 to prepare a paper which will embrace structural characters, 

 -etc., coloured figures of larvae, pupae, and imagines, and will 

 endeavour to place my New Guinea and material from the 

 adjoining islands in the proposed work, in which I hope to 

 receive the same generous assistance from my co-workers. 



I have unsuccessfully endeavoured to locate many of the 

 types. This applies more especially to those of Plotz, and 

 nave been reluctantly compelled to abandon the search. Many 

 of Plotz's species are in the collection of the late Herr 

 Erhardt at Munich. 



Before concluding I would take this opportunity of 

 heartily thanking Colonel Chas. Swinhoe, Messrs. J. A. South, 

 H. J. Elwes, Bethune Baker, H. Druce, A. Bang-Haas, Herr 

 Krepelin, G. A. Lyell, and many others for assistance, not 

 forgetting Mr. G. A. Water house, whose valued help has 

 been of yeoman service to me in the elucidation of many 

 knotty points.

Club of antennae moderate, gradually thickened, tapering 

 to a fine point, bent, not hooked. Forewings in male with 

 costal fold ; vein 5 equidistant from 4 and 6 ; 3 from well 

 before end of cell ; 2 three times as far from base of wing 

 as from end of cell. Hindwings with termen evenly rounded; 

 5 obsolete; 3 from just before end of cell. Hind tibiae 

 densely fringed and with only terminal part of spurs. 



Type corvus, Feld. 



This genus differs from phoenicops, Watson, by the pre- 

 sence of costal fold of d" • The genus extends to the Indo- 

 Malayan Archipelago.
