have on the upperside of the forewing a short and sometimes even a 
quite distinct and longer “ male-mark.” The genus Tronga comes into 
Mr. Moore’s group A of the Euploeina , which is defined as having “No 
‘ sexual-mark ’ or scent-producing organ on forewing.” But there are 
many exceptions to this definition.

Butler. Kirby. Moore. This species may be distinguished from 
E, bremeri , Felder, by its smaller size, the duller colour of the upperside of 
both, wings, being brown, not black, with all the white spots smaller. It 
never shews any traces of a “ male-mark.” It occurs in the plains about 
equally commonly as E. bremeri, though it is found also at somewhat 
greater elevations in the hills, occurring even on the Central Plateau ; 
these latter specimens show only very few white spots.

Distant. This beautiful and large species is found only in the deep forests 
of the plains, never higher thanNamoe Oekor. It flies mostly alone high 
over the small openings in the evergreen forests, and is found all the year 
round, but never in large numbers. There has been much confusion 
regarding the name Euyloea ochsenheimeri. Two species have been so 
called, one by Lucas in 1853, and one by Moore in J857, both from Java. 
Mr. Moore places his own species in the genus Adigama, and Lucas’ 
in Tirana. There has been no Ewploea named ochsenheimeri by Butler, 
as stated by Dr. Hagen. To further complicate matters, Snellen figures 
E. malayica, Butler, as E. ochsenheimeri, Lucas, with which it has 
nothing wha f ever in common.
