Patn'o. Batchian (taken by Wallace ; type, 1 J , in Mil-;. 

 Hope, Oxford, '' Stevens, 1860"). 



In spite of the age o£ the type, it is in very good condition, 

 except that the antennae are somewhat broken. 



In form it resembles 0. formosa, but differs in colour; tlie 

 broad, flat pronotura is characteristic. 



I am very pleased to dedicate it to Professor Poulton, who 

 l)as always placed the Hope Collection at my disposal with 

 the greatest courtesy.
