Ewploeines forming Mimetic Groups

whether the discal spots are actually more variable than the subapical 

 ones. 



The number of each species collected is as follows : — 



E. eleutlio sacerdos Butl. ... ... ... 296 



E. visenda Butl. ... ... ... ... 47 



E. compta Rob. ... ... ... ... 4 



E. peloroides, sp. nov. ... ... ... 3 



Hypolimnas alimena forbesi Butl. ? ... ... 66 



The model is evidently sacerdos. The spots on the fore wing of 

 compta are dyslegnic as is also the band on the hind wing of the 

 Hypolimnas. 



D— AUSTRALIAN GROUP. (Plate IIIa.) 



In Australia, eleutho has become very specialised and forms probably 

 a second species, corinna McLeay, just as a certain Polynesian species 

 has a distinct representative in Fiji. The group is constituted as 

 follows : — 



E. {Crastia) corinna McLeay, figs. 1, 2. 



E. {Calliploea) tulliolus darchia McLeay. 



E. {Calliploea) hymens niveata Butl. 



E. {Crastia) eichorni Stgr., figs. 6, 7. 



E. (Stictoploea) Sylvester Fbr., figs. 4, 5. 



E. {Stictoploea) pelor Doubl., fig. 3. 



E. pelor is regarded by Waterhouse and Lyell ("The Butterflies of 

 Australia ") as a race of Sylvester. This conclusion is borne out when 

 mimetic comparisons are made. In pelor the fore wing has the two 

 discal spots placed farther from the margin, the lower one being 

 placed as in corinna. The band of the hind wing is broken up and 

 clearly resembles the band in corinna. The spots in pelor are dyslegnic, 

 and in the form dardanoides W. and L., all the markings are dusky. 



E. Sylvester pelor occurs at Port Darwin, Daly E., Roper R. 



E. Sylvester f. crithon Misk., occurs at Cape York and on Darnley 

 Islands. 



This form is without spots, and intergrades exist between it and 

 the typical form. Waterhouse and Lyell " consider it probable that 

 crithon is identical with Stictoploea immaculata Butl., from New 

 Guinea." 



E. Sylvester f. dardanus Misk., occurs at Cape York — and on Prince 

 of Wales Island, Bank Island, and Thursday Island. This form is
