3B L. de Niceville — Butterflies of the subgenus Tronga. [No. 1, 



18. Tronga morrisi, Hagen. 



Euploea (Tronga) morrisi, Hagen, Ent. Nach., vol. xxiv, p. 199 (1898); Tronga 

 morrisi, Fruhstorfer, Berl. Ent. Zeitsch., vol. xliii, p. 188 (1898).- 



Habitat: Mentawej Islands (Hagen); Mentawej (Fruhstorfer). 



This species also I have not seen. It is highly improbable I think 

 that two distinct species of Tronga inhabit one tiny group of islets 

 lying to the south of the central portion of Sumatra. Should one 

 prove to be a Tronga and the other a Menama the occurrence of tvro 

 closely-allied but subgenerically distinct species v^^ould be accounted for. 



19. Tronga tenggerensis, Fruhstorfer. 



T. crameri tenggerensis, Fruhstorfer, Berl. Ent. Zeitsch., vol. xliii, pp. 187, 188 

 (1898). 



Habitat: Tengger mountains, 2,000 feet, East Java (Fruhstorfer). 

 I have seen no specimen of this species. See remarks on p. 14. 



20. Tronga biseriata, Fruhstorfer. 



T. crameri, ab. biseriata, Fruhstorfer, Berl. Ent. Zeitsch., vol. xliii, pp. 187, 188 

 (1898). 



Habitat: East Java (Frahstorjer'). 



Mr. Fruhstorfer describes this as an '* aberration " of T. crameri, 

 Lucas, which latter he records from " North and South Borneo, Mt. 

 Mulu," only, and not from Java at all. Probably he intends it to be 

 understood that it is an aberration of his tenggerensis rather than of 

 crameri. There is already a Tronga biseriata (see n, 7, p. 34) of 

 Moore, so as a distinct species it cannot stand in any case. I have not 

 seen it. 



The two following species have been described in the genus 

 Tronga : — 



1. Tronga moorei, Butler, vide Moore, Proc. Zool. Soc. Lond., 1883, 

 p. 267, n. 6, is a Menama. 



2. Tronga nicevillei, Moore, Lep. Ind., vol. i, p. 77, pi. xx (1890), 

 is an aberrant Grastia in my opinion. 



Also Menama mouhotii, Moore, Proc. Zool. Soc. Lond , 1883, p. 265, 

 n. 7, pi. xxxi, fig. 6, male, is in my opinion another aberrant Crastia.
