BUTTERFLISK OF BORNEO, 89 



Tronga pryeri, Moore, P.Z.S. 1883, p. 269. 



The differences between specimens in the Sarawak 

 Museum of E. bremeri (E. Marsdeni, syn.) from Singa- 

 pore and E. pryeri from British North Borneo are so 

 small and so inconstant that I have no hesitation in writ- 

 ing the two species under one name. Fruhstorfer divides 

 the Trongas into two groups : — 



1. Hind wing with a prominent row of submarginal dots. 



2. Hindwing with a double series of very large clear 

 white spots. 



In the former group he places E. bremeri, as a sub- 

 species of E. Crameri, in the latter he places E. pryeri, 

 yet all the specimens of E. bremeri that I have seen 

 should be placed in group 2. In any case the species is 

 rather a doubtful one. It ranges from India through 

 the greater part of the Indo-Malayan region. 



Sub-genus Adigama.
