 1880. The broad black band along the spine, so charac- 

 teristic to the ephippium-vnYieij is present in N"». 20 — 24, 

 but confounds with the darker colored sides of the body, 

 especially on the hind part of the back. — 25 and 26. 

 Adult males , Borneo , mainland opposide Labuan, Frank, 

 1880. These specimens differ in some respects as they have 

 small white points to the hairs of the tail and also to 

 those of the sides of the body and outside of legs. It is 

 a very curious mode of coloration , but I believe it to be 

 an example of individual modification. — 27. Adult male, 

 Borneo, S. Muller. — 28. Adult female, Borneo, Crooeke- 

 wit. Nos. 27 and 28 have no trace of black stripe on the 

 back; N°. 27 has the upperparts brown, head pale brown;
