Very near to E. undularis, of which it is clearly a Bornean race. 

 I know of nothing of which it is likely to be a mimic, unless it be a 

 Bornean form of Euplcca mazares. 



3. Elymnias hecate, sp. n. (Plate XLII. fig. 2.) 



<$ . Alee supra nigro-picea, purpureo certo situ micantes ; anticee 

 striis sub quatuor subapicalibus lilacinis decrescentibus : subtus

 haud macula tee : exp. alar. unc. 2, lin. 10. 



Labuan (Lowe). <S , B.M. 



Another Bornean race of E. imdularis, and possibly a mimic of 

 Euplcea mazares.

Ceylon ( Wenham). d 2 > B.M. 



Tbe Ceylonese representative of E. undularis, its female being 



barely distinguishable from that species, and therefore also a mimic 



of Danais chrysipptts ; the male, however, is a very different-looking 



insect. 



5. Elymnias caudata, sp. n. (Plate XLII. fig. 4.)
