In 1859, Boheman recorded that F. auricularia was parasitised by 

 Digonichaeta setij^ennis. The only other study of this parasite is that 

 of Pantel (1910-1913). The present paper gives a full account of 

 the larval forms, which had not previously been described in detail.

In reply to a question whether a prize of £4,000 should not be offered 

 for the best remedy against Clysia ambiguella and Polychrosis botrana, 

 the French Minister of Agriculture stated that arsenical and nicotine 

 preparations are the most efficient known at present, but that possibly 

 something better may be discovered, although a method capable of 

 aimihilating these old-established pests does not appear probable. 

 The question of control will be more surely solved by a systematic 

 study of the bionomics of these insects than by the institution of a prize 

 open to the public. It therefore seems better to increase the funds 

 of the laboratories and stations of the Service des Epiphyties and to 

 found a Phytopathological Institute such as those established in other 

 countries.
