Euploeines forming Mimetic Groups 31 



fined to Australia, it is probable that peloroides is allied to this, and 

 is a mimic of sacerdos. The more ancestral form is probably jacobensi 

 Koeb. from Wetter, as the Timor race of this species approaches 

 peloroides in the more proximal position of the two discal spots. 



This form is so much like sacerdos that it remained unnoticed for 

 a long time amongst a big series of that form. 



S ? . Upperside with the pattern of pelor Doubl. Fore wing with 

 four subapical spots, the one nearest the costa minute, the second in 

 7 much larger, the third in 6 very large (4 mm. long and 2" 5 mm. 

 broad), the fourth in 5 smaller than the second, a fifth spot in 4 

 below the fourth not larger than the first spot. A discal spot in 3 

 about 6 mm. long, and another smaller one below it in 2. Three 

 small bluish-white costal spots, in the $ , a fourth spot in 5. Hind 

 wing with a postdiscal band of spots as in pelor. An antemarginal 

 series of dots which are only faintly marked. 



Underside of fore wing with subapical and discal white spots as 

 above. A postcellular series of six small bluish-white spots, a bluish- 

 white costal spot and one in the lower end of cell. An antemarginal 

 series of white dots more strongly marked than in pelor. Hind wing 

 with postdiscal band as above. A postdiscal series of seven small 

 bluish-white spots, a second small bluish-white spot in 7 placed 

 nearer the margin, and one in the lower end of cell. A series of 

 antemarginal dots as on the fore wing. 



Ground-colour of both wings very much as in timora and sacerdos, 

 fore wing blackish in proximal half. 



Length of fore wing : S 34 mm., ? 36 mm.
