74 INSECUTOR INSCITI^ MENSTRUUS 



nothrips (a synonym of Idolothrips), in which it was originally 

 described, it is really very close to Gigantothrips Zimmerman,

 venation of the hind wing, and the flattened abdomen of the 

 male with its conspicuously prolonged intermediate segments. 

 Only one species is known ; it inhabits galls on Planchonia 

 valida in Java.
