NOVITATES ZOOLOGICAE XXVI. 1919. 15 



phalaris Fabr. to be drawn up from a bad figure of a Nymphalid to which has 

 been affixed the head of an Agaristid, but I cannot agree to this. I will take 

 an opportunity of inspecting the Jones drawings and collection from which 

 Fabricius described phalaris, as soon as the war work of the owner permits, and 

 try and puzzle out the truth ; but meanwhile, lack of suflScient material pre- 

 vents me from giving a definite opinion as to whether these forms consist of 

 one or several species. For the present I enumerate them imder mygdon Dalm. 

 as forms of one species, not defining their exact status.*]

* I have carefully examined, by the courtesy of Dr. Drewitt, the Jones drawings ; Donovan's 

 figure is a caricature, and the Jones drawing is a good figure of Castnia invaria Walk., which must 

 stand as phalaris Fabr.
