1. Ti'epsichrvis Verhuelli, (^ ? 



What I believe to be the male of this species has recently 

 been received from North-east Borneo ; it differs from T. 

 mi^idanensis (which it most resembles) in the enlarged third 

 subapical spot on the primaries ] like that species it differs 

 from T. Linnei in the absence of spots on the disk of the wing. 



2. Danisepa Schreiberi^ sp. n. 



^ . The smallest species yet described ; nearest to D. Lowii, 

 but with the submarginal spots on the primaries wholly (or 

 almost wholly) blue : secondaries darker and without a trace 

 of the white stripes on the internal area either above or below. 

 Expanse of wings 68 millim.

3. Teracolus Walkeri, sp. n. 



Allied to T. Bcinae, but differing in the colour of the apical 

 half of the primaries, which is crimson instead of magenta- red, 

 and from all the species of the group in the great width 

 (between 3 and 4 millim.) of the dark brown belt dividing the 

 primaries of the male obliquely into two parts ; the wings in 

 both sexes are heavily suffused with grey at the base ; both 

 sexes have a decreasing series of squamose marginal spots on 

 the secondaries, and the female has a straight discal series of
