44 MIMASTRA SUBMETALLICA. 



From the other described species belonging to Mimastra, 

 the present one may be separated by the very long fourth 

 joint of the antennae and the metallic reflection of the 

 elytra. In the female the last joints of the antennae are 

 generally fuscous and the thoracic depressions are more 

 obsolete.

A specimen from Soepajang, Silago (Sum. -Exp.) and 

 Soekadana (L C. van Hasselt). 



The female is considerably larger and one specimen (that 

 from Soepajang) differs in the colour of the antennae , 

 in having the five lower joints piceous above and fulvous 

 below , and the intermediate joints entirely of the latter 

 colour.
