128 INSECTS OF SAMOA.

Without reference to the it is not possible to give the subgeheric position, 

 but I conjecture that the present species will prove to be a Perixera. The 

 palpus and scheme of markings agree with those of the two most widely distri- 

 buted members of that group : P. flavisjnla Warren, 1896 (N. India, Burma, 

 Hainan and Hong Kong, with races (?) in Sambawa and Sumba and in Queens- 

 land, New Guinea and Fergusson Island, the latter being P. lopliosccles Turner, 

 1908) ; and P. argyromma Warren, 1896 (distributed from Ceylon to New Britain). 

 It may even prove a close relative of the latter, notwithstanding its more 

 crenulate margins. 



This species will be figured, in colour, on a plate which will appear in 

 Part III, Fascicle 4. 



Scopula Schrank.

An enormous genus, showing remarkably little structural variation except 

 in secondary sexual characters in the The genitalia, whether in the 

 Palaearctic or Nearctic Eegion, South America, South Africa, Malaya or 

 Tasmania, are quite homogeneous in their essential formation, and all that is 

 yet known of the exotic larvae fully bears out the naturalness of the grouping. 

 Wanting in Chili, Patagonia, New Zealand (excepting one obviously introduced 

 species {vide Meyrick, Tr. N. Z. Inst., xvi, 57, 1883) and the Hawaiian Islands, 

 the genus is otherwise more or less strongly represented everywhere, perhaps 

 least prominent in the Neotropical Region. Including a few which are still in 

 manuscript, I know about 470 named species, besides some 50 others which have 

 not yet been worked out. 



The species upon which Meyrick founded his genus TricJioclada, and which 

 perhaps in some measure connects Scopula with the allied genus Problepsis 

 Lederer, is only known as occurring in Fiji : cpigypsa Meyrick, Tr. Ent. Soc.
