lular meets the median vein at the origin of its second 

 branch. 



These two forms are so much alike that, notwith- 

 standing the difference of neuration, I hardly like to 

 separate them. 



Terinos Viola, n. s. 



Male. Form of T. Clarissa, but the apex of the an- 

 terior wings rather broader and more angulate, the hind- 

 wings a little more caudate. 



Above: violet or violet-brown, the velvety patch ex- 

 tending over the upper discoidal vein on the anterior 

 wings. Hind- wings rich violet-blue, or brown tinged 

 with violet, a velvety patch at the outer angle as in T. 

 Clarissa, a pale white or brownish patch on the outer 

 margin, and a submarginal dusky or bluish waved line. 



Beneath : rufous-brown, with waved brown markings 

 on the basal portion of the wings, the hind-wings with a 

 pale submarginal band enclosing a broad zigzag rufous- 

 yellow line, within which are four rufous spots. 



Expanse 3*5 inches. 



Ba6.— Singapore, Sumatra (Wallace) . 



Distinguished at once by its angular form and peculiar 

 colouration. The Sumatra specimen is less deeply 

 coloured than that from Singapore, and the lower disco- 

 cellular meets the median vein a little beyond the origin 

 of its second branch, while in the darker Singapore form 

 the two meet at the same point. The two forms are, in 

 other respects, so much alike, that I hesitate to separate 

 them.
