The most striking feature of the collection is the comparative 

 cosmopohtan character of the species. Not a single species peculiar 

 to the islands was found; even the new species described below 

 being all closely allied to well-known and widely distributed forms. 

 The species affecting fruit trees (Cifnis, etc.) were introduced with 

 nursery stock quite recently. 



The writer is under great obligation to Prof. T. D. A. Cockerell,
