A LIST OF THE BUTTERFLIES OF BORNEO. 145 
Sandakan (Pryer); Labuan (Low); Trusan (Everett) ; 
Lawas, Trusan, Tambak, Santubong, Matang, Kuching, Bau, 
Lundu (Sar. Mus.) ; Banjarmasin (Wahnes). 
Distribution; India (?) and Malaya. 
This genus is distinguished from Arrhenothriz, de Nicév. 
by the presence of an additional sub-costal nervule in the fore- 
wing. 7 
A long series from Sarawak bears out Druce’s note that in 
Bornean examples the white band of the hind-wing varies in 
width; and many of them are indistinguishable from A. pen- 
cilligera in this respect. 
Injury. 3, small symmetrical bite removing the inner anal 
spot and tail in both hind-wings. 
Genus, ARRHENOTHRIX, de Nicéy. 
456. Arrhenothna lowi, H. H. Druce. 
Arrhenothrix low, H. H. Druce, Proc. Zool. Soc. Lond.

wing are hardly distinguishable in the Sarawak specimens.

fore-wing.
