At some of the foregoing references, not only are new specie-* 

 described but others are ciitically discussed. For instance. 

 MollendorflP's paper, No. 32, although containing no descriptions of 

 new species, is very importaut, since it treats very fully upon a large 

 proportion of tlie known forms from China. Gredler's paper (No. 22ii) 

 is useful also, since it contains a list of all the species and varieties 

 described by him, with references to the publications in which the 

 descriptions have appeared.
