1901.] L. dc Niceville — Butterjlies of the subgenus Tronga. 37 



Euplcea bremeri, var. pryeri, Distant and Pryer, Ann. and Mag. of Nat. Hist., fifth 

 series, vol. xix, p. 47, n. 12 (1887). 



Habitat: Sandakan, Borneo (Moore)-, North Borneo (Fruhstorfer) ; 

 Sandakan, Borneo (Distant and Pryer), , 



Dr. Moore has sent me a sketch of the type male of this species, 

 none of the specimens I sent to him being identical. Its chief 

 peculiarity appears to be the presence of a complete double series of 

 rather largje spots on the hindwing. Mr. Fruhstorfer takes T. pryeri as 

 the type of his second division of the genus Tronga, based on this 

 character, and gives heylsertsii, Moore, niasica, Moore, nientawica, Hagen, 

 and nicevillei^ Moore, as subspecies of pryeri, though why he gives 

 pryeri precedence over niasica, the latter being the older species, and 

 hrookei over lorza^ for the same reason, is best known to himself. 

 Though I sent no typical specimens of T. pryeri from Borneo to Dr. 

 Moore, I possess several of both sexes that agree with his description 

 and sketch of that species, and it is in my opinion another synonym of 

 T, crameri, Lucas. 



15. Tronga heyl^rtsii, Moore. 



T. heylcurtsii, Moore, Lep. Ind., vol, i, p. 79 (1890) ; E. (Tronga) heylsertsii, 

 de Niceville and Martin, Journ. A.S.B,, vol. Ixiv, pt. 2, p. 371, n. 21 (1896) ; T, pryeri 

 heylaertsi, Fruhstorfer, Berl. Ent. Zeitsch., vol. xliii, p. 189 (1898). 



Habitat: Sumatra [Moore); Sumatra (de Niceville 3iiid Martin) ; 

 Sumatra; Malixcc^ (BVuhstorfer). 



From the description alone 1 can identify this species without diffi- 

 culty, as it is the commonest form of Tronga occurring in Sumatra. It 

 is another synonym of T. crameri, Lucas. 



16. Tronga pagenstecheri, Hagen. 



Euplcea pagenstecheri, Hagen, Jahr. des Nass. Ver. fiir Natur., vol. xlix, p, 182, 

 n. 18, pi. ivj fig. 8, male {189Q) ; Tronga crameri pagenstecheri, Frnhatorier, Berl. 

 Ent. Zeitsch., vol. xliii, p. 188 (1898). 



Habitat: Ba wean Island ( JBfa^en) ; BsLwesbu (Fruhstorfer). 



I have not seen this species. Dr. Hagen says that it comes into 

 Moore's subgenus Menama, near M. lorzas, Moore, [nee Boisduval], while 

 Fruhstorfer puts it in the subgenus Tronga. 



17. Tronga mentawica, Hagen. 



Euplcea (Tronga) mentawica, Hagen, Ent. Nach., vol. xxiv, p. 199 (1898) ; Tronga 

 pryeri mentawica, Fruhstorfer, Berl. Ent. Zeitsch., vol. xliii, p. 189 (1898). 



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

 I have not seen this species.
