across the disk and traversed by the dark veins with streaks 

 between, as on the outer half of the anterior wings ; two dark 

 bars cross the cell, and there is a crimson elongate spot 

 parallel witii the outer margin between the submedian nervure 

 and the lowest median nervule ; the costal margin is pale and 

 tinged with a bluish shade. 



Underside similar to the upperside, but paler. Anterior 

 wings with the crimson bars across and at the end of the cell 

 wider and more distinct, and a small black spot below the 

 median nervure at its junction with the lowest median ner- 

 vule. Posterior wings with two crimson bars crossing the 

 cell, two crimson spots below the costal nervure and upper 

 median nervule respectively, another crimson spot on the 

 costal margin near the precostal nervure, and another at the 

 base; on the outer margin at the ends of the dark streaks 

 between the veins is a row of crimson spots, those nearest the 

 anal angle the most distinct and those in the middle nearly 

 obsolete ; the inner margin from the base to the anal angle 

 is broadly edged with crimson. Antennse black, the collar 

 and palpi crimson. 



Expanse of wings 2^ inches. 



One specimen only.

Dichorragia nesseus. 



Male. — Upperside. Dark bluish green. Anterior wings 

 with the cell crossed by three black bars, that nearest the base 

 nearly obsolete ; beyond the cell, across the disk between the 

 veins, is a curved I'ow of indistinct greyish spots, the second 

 and third of which are elongate; a submarginal row of 

 sagittate grey markings, elongated inwardly to the extent of 

 about one third of the wings, those towards the apex being 

 more elongate and narrower than the others ; there are no 

 spots on the outer margin. Posterior wings more bluish green 

 than the anterior wings and without grey markings, except 

 three small hastate lines near the apex, with grey lines at 

 their base, the lowest almost obsolete ; beneath these, on the 

 outer margin between the veins, is a series of black hastate 

 spots. 



Underside. Anterior wings bluish black, with the spots 

 beyond the cell more distinct and the bars crossing the cell 

 and a small spot beyond violaceous ; the sagittate markings 

 as on the upperside, but more distinct. Posterior wings 

 olivaceous, the hastate spots at the apex as on the upperside,
