104 BUTTERFLIES OF BORNEO. 



Gruppe und zwar in das sub-genus Bruasa, Moore." 

 This is quite wrong", for Grose-Smith in 1892 (1. c.) 

 described both sexes of an Elymnias of the sub-genus 

 Bruasa from Borneo under the name of Elymnias 

 borneensis ; the male is blue above and is a mimic 

 of the Euploeine butterfly Trepsichrois claudius, the 

 female resembles the females of other species of the 

 Bruasa section and is not'a Pierine mimic as is the female 

 of Wallace's species. Grose-Smith's name borneensis 

 being then already occupied by Wallace's species, I 

 venture to propose the new name trepsickroides. To 

 make " confusion worse confounded" Grose-Smith de- 

 scribed as the female of his E. borneenis, the female of 

 another species of Elymnias of the section Bruasa — 

 E. konga — the male of which was described by him in 

 1899. (A.M.N.H. p. 317.) An undoubted female of 

 E. penanga trepsickroides (E. borneensis Grose-Smith ) 

 from N. Borneo is in the Sarawak Museum collection 

 and is now described for the first time : — Very like the 

 female of E. penanga, Westwood, but the sub-apical 

 white fascia on the upper-side of the fore-wings nar- 

 rower and more outwardly oblique, the costa of the 

 fore-wing striated with white. Underside as in the 

 male but less rufous and darker, the sub-costal primrose- 

 coloured spot, larger than in the male. Expanse 65 mm. 

 Hab. N. Borneo. 



74. Elymnias abrisa, Dist. 



Elymnias abrisa, Distant A.M.N.H. 1886, p. 531. 

 Sub-sp. E. abrisa konga, Grose-Smith. 



As stated above, Grose-Smith's description of the 

 female of his E. borneensis is in reality the description of 

 a female konga ; it is very like the female of E. abrisa, 

 forma typica, but has more white on the upperside of 

 both wings. 



The following is a table of the species and sub-species 

 of the section Bruasa of this genus.
