M. lie Niceville when describing (I.e.) the Snmatran specimens of <'k. durnj'ordi 

 as a distinct species (I) avoided giving any differential characters between connecte.ns 

 and the Malaccan durnfordi ; he compares it with the more deviating nickoli from 

 Burma and standinyeri from Java. As the single specimen of Ch. durnfordi 

 durnfordi which is known is in the Triiig Museum, we are enabled to point out the 

 above-mentioned differences. Bnt these differences are so slight that they may 

 turn oat to be purely individual, considering that the Sumatran specimens are not 

 at all constant in the size of the white markings. As M. de Niceville has, however, 

 given a name to the Snmatran examples, we must keep the insects in cjuestiou 

 subspecifically separate, until further material from the Malay Peninsula proves 

 that connectens is a synonym of durnfordi durnfordi. 



The insect is as rare in Sumatra as it is elsewhere. It " occurs in heavy forest 

 on the lower ranges and outer spurs of the Battak Mountains," says Dr. Martin, 

 who took his first specimen in 1888 at Eoemeh Kenangkong. 



Dr. Hagen received also two specimens from the Battak Mountains : his 

 collector captured a c? at Bandar Kwala in Serdang, and Dr. Hagen himself found 

 a S in Serdang in the dense forest.

^ Wiiiffs above darker than in the preceding races, the basal area of both wings 



being mummy brown, not chestnut. Forewing : discal spots M' — SM- shaded 



with brown, much closer to postdiscal ones than in the other races, spot II- — R' 

 elongate, thin, more distal than in the other races, the series less irregular in 

 position ; spots beyond upper angle of cell obsolete ; postdiscal spots R' — SM' very 

 wide, spots SC" — R^ small, the upper one often absent, postdiscal patch at internal 

 margin present, the discal one vestigial ; admarginal dots absent or faintly vestigial, 



submediau ones sometimes present, but very thin. Hiudwing : median bars very 



obscure, discal interspaces with little huffish scaling ; discal bars much less arched 

 than in the other races, especially bars R- — SM-, hence proximal edge of white area 

 much less convex between veins : postdisco-submargiual black patches, often with 

 violet scaling at edges, pointed upon internervnlar folds, the middle ones often 

 reaching the very heavy admarginal line, patches R' — M' not broader than the 

 interspaces between them ; veins within white area generally a little heavier black 

 in the other forms. 



Underside. Forewing : median bars R' — .SM" standing in a straight row, 



the bars themselves angled, bar R'— R' about 1 mm. from bar R' — R= ; median 

 interspaces R' — SM' much wider than discal ones, the latter narrower than post- 

 discal ones ; outer margin much shaded with brown, especially below apex. 



Hindwiug : discal interspace SC" — R' wider than median one.
