Underside the same. Head, thorax, aad abdomen black ; face aud front of 

 thorax with a few white scales ; an orange spot beneath at sides of shoulders ; 

 abdomen beneath whitish. 



Expanse of wings : 48 mm. 



One ? from R. Dagua, Colombia (Rosenberg). 



0. Dioptis restricta sp. no v. 



Like D. areolata Wlk. in markings, l)ut not so deep a black, and the black 

 markings not so strongly developed ; as a consequence all the hyaline spaces 

 between the veins are longer, and squarer, not so much rounded off at their 

 extremities, the whole insect appearing paler. In particular the interval between 

 veins 3 and 4 in both wings remains clear, not filled up witli black. An orange 

 spot on shoulders at side. 



Expanse of wings : 38 to 44 mm. 



Four ? ?, one from Rio Janeiro, one from Petropolis, the other two without 

 locality label. 



This insect has probably been confounded, at least in the ? , with areolata Wlk.; 

 but areolata is smaller and deeper black. 



10. Dioptis uniguttata sp. nov. 



Forewings : hyaline ; the costal aud inner margins narrowly black ; all the 

 veins black ; the ajiical two-fifths black, containing a white oblique fascia from below 

 costa at two-thirds to vein 4, and a round white spot above anal angle between 

 veins 2 aud 3 ; the discocellular and upper outer half of cell black ; space between 

 discocellular mark and the apical l)lack area occupied by three hyaline spots, of 

 which the uppermost is faintly tinged with white. 



Ilindwings : with the costal margin narrowly, the hiudmargin broadly black, 

 the latter containing witliin its inner edge a curved orange streak ; all the veins 

 black. 



Underside like upper. Palpi black above, white beneath ; face black margined 

 with white ; vertex, thorax, and abdomen black ; a white spot at base of antennae 

 and one at centre of vertex ; base of the patagia orange ; abdomen white beneath. 



Expanse of wings : 40 mm. 



One <? from Bogota. 



Near D. cheledonis Drnce. 



11. Ephialtias adiante. 

 (Josia adiante Wlk. ii. p. 303). 



This species, of doubtful locality, has been sunk to E. vittula Hiibner ; but 

 a d from Popayan, Colombia (Lehmanii), agrees exactly with Walker's type in the 

 British Museum Collection, aud is clearly not identical with vittidn. The forewings 

 are decidedly narrower than in that species ; the transverse yellow bar of forewings 

 is not only narrower, but much more oblique, starting from before the middle of 

 costa ; and the yellow central area of hindwings is both broader and of more 

 uniform width throughout. 



Both streaks are of a deeper orange tint than in mttida.
