172 Mr. A. G. Butler on a new Butterfly. 
to New Zealand and probably to Science,” to which he gave 
the name of Genus? helms?; this species he referred to the 
Nymphalide, but did not venture to assign it to any group 
in that family. 
As Mr. John D. Enys, who is now in England, has brought 
over the type specimen of this butterfly for my examination, 
with the request that I will determine its position and name 
the genus, | have great pleasure in doing so. The genus 
being a new one and greatly resembling the genus Dodona of 
Hewitson both in form and general coloration, I propose to 
call it 
DoDONIDIA, gen. nov. 
This genus, as indicated by Mr. Fereday, belongs to the 
great family Nymphalide (subfamily Satyrine), and although 
it corresponds most nearly in form with Oorades (a New- 
World genus), it appears to me to be more closely related to 
the Australian genera Argynnina and (rectoneura, from the 
former of which (apart from its different form) it chiefly differs 
in the shape of the discoidal cell of the secondaries, which is 
acutely pointed instead of truncated, owing to the length and 
obliquity of the discocellular veinlets. ‘The body, inclusive of 
palpi and antenne, corresponds closely with that of Argynnina; 
the style of coloration of the wings is most like that of A. 
lathoniella: the primaries are triangular, but with the apex 
and external angle obtusely rounded off; the costal margin is 
nearly straight, slightly incurved before the middle, and very 
slightly convex from apical third; the outer margin is nearly 
straight, rather oblique, slightly convex at apex, and incurved 
at external angle to meet the inner margin, which is also 
nearly straight ; costal vein extending to apical third; sub- 
costal five-branched, the first branch only emitted before the 
end of the-cell, the second, third, and fourth at about equal 
distances beyond the cell, the fourth and fifth forming an
