This work is the most important that has ever been offered to working and 

 scientific lepidopterists. It contains series of exhaustive monographs which no 

 entomologist should be without, and if he be dealing with the same super- 

 families, he will find in these volumes a mass of detailed information such as 

 never has been got together before on all the branches relating to the species 

 treated. At the same time, the discussion of general biological problems, and 

 the great amount of detail relating to such problems, give the books a value for 

 a class of workers quite apart from the British and Continental lepidopterists for 

 whom they were primarily intended.
