Mr. Ernest Andre's conception of this subfamily is erroneous ; he has 

 placed in it a number of genera that do not belong to the family 

 Thy7inidce. at all, but are genuine Myrmosids, and represent my tribe 

 Chyphotini. Moreover, Andre has incorrectly classified all of these 

 genera in the family Miitillldce, an error Fox and myself also fell into 

 years ago, before we had studied the Thynnida. 



Mr. Frederick Smith, of the British Museum, was apparently the first 

 to point out that Methoca belonged to the ThymiidcB, although he still 

 retained it among the Mtitillidce. Dr. David Sharp, in Cambridge 

 Natural History, Vol. 5, p. 96, has also correctly placed Methoca with the 

 Thynnides and gives a good figure of both sexes of M. ic/meumo?iides,
