42 Fruhstorfer states that this subspecies “ does not differ from Ur chi 
in any essential character, as far as I can tell from Distant’s figure,” and 
he suggests that birchi, which is only known from a single Singapore 
specimen, really comes from Borneo. 
A good series in the Sarawak Museum from several localities in Borneo 
agree in one feature, wherein they all differ from birchi ; that is, the greater 
development of the black scaling at the base of the hind wing below. In 
occulta this is slightly concave below costa as if to make room for the 
costal ocellus, and then markedly convex before continuing to the inner 
margin. In birchi this basal region is obliquely marked off from costa 
direct to inner margin. It appears to be a local race in Borneo; the late 
Messrs. Bartlett and Shelford, who were so successful in forming the greater 
part of the Sarawak Museum collection, from 1894 to 1904, failed to obtain 
it. The establishment of prolific Homo sapiens and his works in Singapore 
is sufficient to account for the rarity and probable extinction of Tcenaris 
horsfieldi birchi. 
43 Omitted by Shelford. 
44 Shelford records both amethystus and wallacei from Borneo.
