108 BUTTERFLIES OF BORNEO. 



cell has a whitish streak closing it and two transverse 

 brown lines between the discowal streak and outer spot ; 

 the sub-marginal series of spots is indistinctly doubled 

 and suffused slightly with violaceous ; on the hind-wings 

 the abdominal margin and greenish, there is a whitish 

 mark below the pre-costal nervure, the discal band is 

 still more reduced than on the upperside, the inner sub- 

 marginal series is whitish and with internervular obso- 

 lete dashes, brown in colour passing from it inwards, 

 the outer series is violaceous. 



Body and legs beneath greenish. 



Expanse, 51 mm. Hah. Mt. Matang, 3200,' Sarawak 

 (June). Type and only known specimen in the Sarawak 

 Museum. The species is remarkable for the great reduc- 

 tion of the white markings on the upperside. 



[A little detail in the markings on the upperside of 

 species of the genus Athymae seems to have hitherto 

 escaped notice. In nearly all the species — A, sclenophora, 

 Koll. and A. zeroco, Moore are exceptions, — the trans- 

 verse discal white band of one hind-wing is continuous 

 with the corresponding band of the other wing by means 

 of a patch of white hair covering the dorsum of the first 

 abdominal segment ; in the males of A. sclenophora and 

 A. zeroca the discal bands are broader and are more 

 oblique and so touch the abdominal margin of the wing 

 at a lower level than they do in such a species as A. 

 kresna, Moore, and we find that the band of one wing is 

 not connected through an abdominal tuft of white hair 

 with the other band ; in these details of markings at any 

 rate these two species approach the genus Limenitis 

 but it is interesting to note that the females have these 

 discal bands more transverse and connected one with 

 the other across the abdomen in the manner so charac- 

 teristic of other othymae. The species of the genus 

 Neptis which serve as models to so many mimicking 

 Athymae in no case known to me have the discal bands 

 of the hind-wings connected by an abdominal patch, even
