of a Diodosida than of a Nephele; but in structure it appears 
to agree with the latter genus. 
7. Diludia macromera, sp. n. 
Nearly allied to D. discistriga, with which it has hitherto 
been associated, but differing in its greatly superior size, the 
more distinctly defined markings on the wings, the more 
elongated apical patch on the primaries, the darker seconda- 
ries, with distinct grey anal patch crossed by a black stripe. 
Expanse of wings 130-142 millim. 
Three examples, Sarawak (H. B. Low). 
8. Pseudosmerinthus Cartert, sp. n. 
Allied to P. marginalis $ (a species closely allied to P. 
Pechuelit, see Dewitz, Mitth. Miinch. ent. Ver. 1. Taf.i. fig. 4, 
1879), but differing in having black spots on the wings, as in 
Triptogon, and dark lines across the primaries, as in Poly- 
ptychus. Primaries above sericeous whity brown, crossed by 
four dark brown lines, the first and third of which are oblique 
and parallel, the second zigzag, the fourth transverse to the 
second median.interspace, thence to external angle sinuated 
and indistinct; area between the first and second lines darker 
than the ground-colour; area between the third and fourth 
lines darker internally; apical area with darker nebule; a 
conspicuous triangular blackish spot near the base ; a whitish- 
pupilied dusky spot at the end of the cell and a large irregu- 
lar dark brown spot on the internal border close to external 
angle: secondaries rosy grey, pale and sericeous on the costa, 
slightly dusky towards external borders; a large diffused 
whitish patch, enclosing two closely approximated black spots, 
at anal angle: body whity brown; thorax with a longitudinal 
dark-brown dorsal line. Under surface pale sandy brown: 
primaries with a submarginal series of black dots on the veins ; 
fringe dark brown: secondaries crossed by two parallel dusky 
discal lines; fringe dark brown, varied with cream-colour. 
Exxpanse of wings 71 millim. 
Aburi, Gold Coast (EZ. T. Carter). 
The preceding species clearly proves that the Panacra an- 
dosa of Walker should have been referred to Pseudosmerinthus ; 
its elongated wings and style of marking induced me to place 
it in Polyptychus, from which, however, its non-dentated pri- 
maries at once distinguish it. 
9. Pseudosmerinthus virescens, sp. n. 
Even nearer to P. submarginalis than the preceding, the
