Note on Doryphora cruciata. 

 Since the description of this species has been in type I have discovered that H. 

 Siiil has described a pale variety under the name of D. cruciata ; 1 have therefore 

 been obhged to wiihdiaw ihe name Euphrusyne, proposed by myself for the insect, 

 and to substitute that given by ii. Sliil.
