Australia {Becker, Wood) ; Navigators' Islands. B.M. 



The typical C. erotus, although perhaps a second form of the female of this species, 

 may at once be distinguished by its slightly superior size, deeper colouring, the glossy 

 character of the primaries above, the broader black border to the secondaries, and the 

 deep reddish coloration of the under surface of all the wings, which almost obliterates 

 the mottled hatchings so distinctly seen in C. erotoides.

Nearly allied to the preceding species.

I have been unable to obtain the above work, and therefore have failed to identify 

 the species. 



Genus 14. Darapsa, Walker. 

 Darapsa, Walker, Lep. Het. viii. p. 182. gen. 22 (1856). 



This genus was founded upon most heterogeneous material, the first three species 

 being referable to Hubner's genus Otus, the fifth to Walker's genus Diodosida, the sixth 

 and eighth to the genus Daphnis of Hiibner, the seventh, ninth and tenth to Chcei'o- 

 campa of Duponchel ; there therefore remains only the fourth species, allied to Charo- 

 campa, but apparently sufficiently distinct. It differs as follows : — 



Primaries comparatively shorter, costal margin more arched at apex, outer margin 

 much arched and shorter, inner margin strongly waved, almost sigmoidal ; secondaries 

 comparatively much longer and narrower. 



Darapsa rhodocera. 

 Darapsa rhodocera, Walker, Lep. Het. viii. p. 184. no. 4 (1856).

Most like the C. clotho group of Chcerocampa in colouring.
