Hah. Baram, Sarawak. 



Type. Adult female. B.M. no. 0. 7. 29. 14. Collected 

 and presented by Dr. Cliarles Hose. 



This Baram bat differs from the Javan L. JiorsfielcU by its 

 much smaller and narrowei* brain-case, and still more so from 

 the other Sarawak and N. Bornean Cxxamples of the group, 

 which have the brain-case more swollen than in true kors- 

 fieldi. Tiiese other Bornean specimens I refer provisionally 

 to Miller's L. carima(ce, though I think it very doubtful if they 

 should be kept distinct from L. horsfieldi. But the skull of 

 Zi. lepidus is conspicuously different from any of them.

 narrowing sharply to apex. Above differs from both singlia- 

 pura and s. indistincta in having the black on outer ^ of fore 

 wing absent below vein 2, and reduced to a narrow submar- 

 ginal cloud between veins 2 and 3. Below the yellow of 

 hind wing is darker and the submarginal patches smaller.

 Above more strongly clouded with black. Below the yellow
