the Australian Lymantriadge. 471 



More recently, Mr. K. Jordan has published an elaborate 

 paper on the Asota section of the group (Novit. Zool, 

 1896, p. 59) ; and Col. Swinhoe has catalogued the species 

 of Nyctemera in the British Museum (Tr. Ent. Soc, 1903, 

 p. 53). From both these papers I have derived help. 



A. Hind-wings with 8 anastomosing shortly with 

 cell near base. 

 B. Palpi porrect or obliquely ascending ; 



second joint short 1. Nyctemera. 



BB. Palpi up-turned ; second joint moder- 

 ately long and closely appressed to 



frons 2. Arginci. 



AA. Hind-wings with 8 not anastomosing with 

 cell. 

 B. Hind-wings with 8 approximated to cell, 



not connected 3. Digama. 



BB. Hind-wings with 8 approximated and 

 connected with cell. 

 C. Palpi with terminal joint less than 

 J second ; ^ without costal reti- 

 naculum 4. Agape. 



CC. Palpi with terminal joint nearly as 

 long or longer than second ; ^ 

 with costal retinaculum .... 5. Asota. 



Genus 1. Nyctemera. 



Nyctemera, Hb., Verz., p. 178; Meyr., Proc. Lin. Soc. N.S.W., 

 1886, p. 759. 



I am unable to follow Col. Swinhoe in rejecting this 

 name in favour of Deilemera, Hb., as his action rests upon 

 the assumption that the first-named species of a genus must 

 be necessarily the type. There is some variability in the 

 $ antennse and the length of the terminal joint of the 

 palpi in the Australian species, but I do not regard these 

 points of generic value in this instance. Veins 6 and 7 

 of the hind-wings may be connate or stalked in the same 

 species.
