THE SPECIES OF THE LEPIDOPTEROUS 

 GENUS INO OF LEACH, 



together with some preliminary remarks on local 

 varieties.

It was my intention to have written a monograph of the 

 genus Ino, Leach {Procris, O., B.), possessing a tolerable 

 amount of materials for such a work myself, and having 

 besides obtained through the goodness of my entomological 

 friends, to whom I here beg to express my best thanks, much 

 additional material. The specimens sent me by Professor 

 Zeller were of extreme value to me, comprising as they did 

 types of his nev/ species. The difficulties I encountered in 

 my investigations have been however so great that I have 

 only carried out very incompletely my original intention. 

 The differences between individual species consist for the most 

 part of such inconstant characters, that an absolute certainty 

 on the specific distinctness can only be obtained by observing 

 the living specimens. Probably the discovery of the earlier 

 stages of these species may furnish us with more positive 

 data, although one is apt to expect too much from that 

 quarter, since the larvse may be just as liable to vary
