220 AUSTRALIAN RIlorALOCERA : LYC.KMD.E, III., 



Unfortunately I have not been al)le to secure a large series of 

 undamaged specimens, though what I have show a certain 

 amount of variation. This species is easily recognised by the 

 four black spots, and the orange blotch near anal angle on under- 

 side of hindwing. In Australia its range is from the Richmond 

 Eiver to Cairns {$ 7, 9 10). 



Nacaduba, Moore. 

 Lep. Cey. i. p. 88, 1881; de Xicev., Butt. Ind. iii. p. 141, 1890. 



Fore wing triangular; costa arched, apex sometimes rounded, 

 sometimes acute; outer margin sometimes slightly convex, some- 

 times straight; costal nervure anastomosing with 1st subcostal 

 nervule for a distance var3'ing in the species and then running 

 free to costa. Type N. promiuens, Moore. 



This irenus contains species that are tailed and also some that 

 are tailless; in fact ^Y. noreia (2^. ardates) is said to have both 

 tailed and tailless forms. The distance for which the costal 

 nervure and the first subcostal nervule are joined is not constant; 

 and the terminal portion of the costal nervure is sometimes very 

 dithcult to see, giving almost the neuration of Utica, Hew., a 

 closely allied genus. The outer margin of the hindwing in most 

 species is rounded, but in some it is nearly straight. 



Most of the Australian species are very common and occur in 

 most collections, l)ut under a great diversity of names. They do 

 not seem to vary greatly within Australian limits, but species 

 passing under different names with onh' minor differences occur 

 in many of the Polynesian Islands. 



Miskin in his Catalogue (1891) places these insects, with two 

 exceptions, in the genus Lauipides; but in the modern acceptance 

 of that genus, this is wrong. He seems to have only discrimin- 

 ated between Lycrmia and Lampides by placing in the former 

 tailless and in the latter tailed forms. I place one species, N. 

 mackayeusis, in this genus only provisionally. 



The males may be recognised as follows : —
