LAMEERE'vS CLASSIFICATION. 

 Yet another pretentious scheme of the classification of 

 Diptera is that of Prof. Aug. Lameere of the Univer- 

 sity of Brussels, which has very recently appeared.* 

 The meritorious part of this ambitious attempt is the 

 endeavor to apply the only real criteria in a true classifi- 

 cation of insects, phylogeny. The author, however, is 

 in deeper water than he suspected; but the scheme is 

 worthy of reproduction because of several suggestions, 

 though its inconsistencies clearly show that the author 

 has not a wide acquaintance with the order.
