HYPOLYCJENINJE. S3 



convex ; costal nervure strongly curved at the base, then slightly curved, ending at 

 the apex of the wing ; first sub-costal nervure arising well before the apex of the cell, 

 curved at the base, then straight ; upper discocellular nervule outwardly oblique, 

 slightly concave ; lower discocellular nearly upright (only slightly outwardly oblique), 

 slightly concave, a little longer than the upper discocellular ; second median nervule 

 arising quite close to the lower end of the cell ; first median arising somewhat nearer 

 to the lower end of the cell than to the base of the wing ; sub-median nervure straight ; 

 internal nervure straight at the base, lying close to the sub-median nervure, then 

 curved towards the abdominal margin. Antennae short, about half the length of the 

 costa of the forewing, with an elongated, rather slender club ; palpi porrect, naked, 

 third joint long. Eyes naked. 



Type, " Camena " cleohoides, Elwes. 



Of the genera with two sub-costal nervules only to the forewing, Britomartis 

 seems to be nearest allied to Ilypolycsena, Felder, of which H. tinolus, Felder, from the 

 Philippines, is the type. Herr George Semper considers H. tmolus to be a " variety " 

 only, or more properly a " local race " of H. eryliis, Godart. From the latter species 

 B. cleohoides difi"ers in the forewing being shorter ; the " male mark " somewhat 

 differently placed, occupying a much larger area in the cell ; the second sub-costal 

 nervule arises twice as far from the base cf the first sub-costal as from the origin of 

 the upper discocellular nervule,* in //. erylus the exact opposite obtains ; the second 

 median nervule arising further from the lower end of the cell ; and the eyes being 

 apparently naked instead of hairy. From the genus Chliaria, Moore, of which 

 Hypolycsena oihona, Hewitson, is the type, it may be known by the naked eyes, 

 and by the second sub-costal nervule of the forewing being far removed from, instead 

 of close to, the first sub-costal at its origin ; the hiudwing also is longer and narrower. 

 Britomartis has male secondary sexual characters, which Chliaria entirely lacks, 

 (de Niceville.)

Most like Camena cleobis, Godart, but differs in having in the male a large round 



* Actually there is no upper discocellular nervule in this genus, what I have described above as that 

 veinlet being the basal portion of the upper discoidal veinlet, the middle discocellular veinlet arising from 

 the upper discoidal some distance from the base of the latter.
