Lepidoptera of the Amazons, 23 



dusky patch ; fringe brown ; body wliity-brown, slightly 

 tinted with pink: expanse of wings 1 inch 4 lines. 

 Villa Nova de Parentins, 5th April, 1874. 



The pattern of the primaries in this species is quite 

 like that o^ ^' Heliophobus^'' dissectus, Walker, from Ceylon, 

 to which it is evidently nearly allied. The two genera 

 can at once be distinguished by the antenna^ which in 

 Dar(jida are simple in both sexes ; the latter genus should 

 perhaps be placed near to Dianthcecla* 



It is just possible that Sepp's P. pliytolacca may be 

 D. sinyularis, but his figure is by far too rough to enable 

 me to form any decided opinion respecting it. 



Family APAMIIDtE.

Primaries above fuliginous-brown, sericeous; costal 

 border crossed by short blackish dashes; a very irregularly 

 zigzag black line ci'ossing the wing at basal third, limiting 

 the central band internalh^, the latter slightly darker than

 white, edged with black, and with a testaceous or white 

 outer margin ; a blackish streak from the reniform spot 

 to the inner margin ; outer margin of the central band 

 sinuous and black, not crenulated or dentated ; a dusky 

 discal line parallel to, and just beyond, the central band, 

 and a submarginal line also parallel to it ; secondaries

 greyish apical border, and narrow interrupted blackish 

 marginal line ; thorax fuliginous-brown, abdomen greyish- 

 brown ; wings below altogether paler ; primaries greyish, 

 the internal area, reniform spot, inferior border of discal 

 and submarginal lines, Avhite ; the discal and submarginal
