genus in Sumatra, but according to Dr. Martin, besides D. Europa F., 

 D. Manthara Felder (Mekara Butl.) is said to occur also in low lying districts 

 in Sumatra. The individuals from Java of species occurring also in British India 

 frequently differ considerably from the latter in the shade of colour, at least in 

 so far as can be judged from the figures given by Moore. The so-called 

 seasonal differences, illustrated by Moore, I have been unable to discover in 

 Java. I must, however, admit that since the majority of Debis species are 

 fairly rare in Java no large series of these are available for comparison, except 

 as regards D. Europa ¥. and D. Rohria F., but of these Moore also knows 

 no seasonal varieties. To judge from Moore's figures two types of larvae appear 

 to occur among the various species but I have met with only one of them 

 in Java. 



Fruhstorfer considers the species of Debts, except D. Rohria F., to be 

 twilight butterflies ; as a matter of fact they are never seen on the wing in 

 day-time except when disturbed.

The accompanying figures of the present species are good, only in many 9 

 the colour of the upper side is much more dull yellowish-grey than is shown 

 in the illustration. The <S figured by Moore and described by Bingham does 

 not agree with the Java specimens nor quite with those figured cis from Java 

 by Fruhstorfer. 



The caterpillar feeds on bamboo leaves (Bambusa sp.). It is of slender
