types of latirentina from Cape Breton Is. (Thaxter), also in the Cam- 

 bridge Museum, are considerably smaller than those of interior and 

 show a rather broader black border ; they appear to represent a slightly 

 modified racial form of interior. 



EUREMA LISA Bdv. & LcC. 



In Dyar's list and in our own Check List, following Godman and 

 Salvin (Biol. Cent. Am. Rhop., II, 162), this species has been made 

 a synonym of eutcrpe Men. (1832, Bull. Soc. Imp. Nat. Mosc. 199) ; 

 this is probably due to the fact that these authors have accepted the 

 date of the title page (1833) of the Lep. Am. Sept. as that of the whole 

 work whereas this work was issued in parts commencing in 1829 

 {vide Hagen. Bibl. Ent. p. 64). Scudder in the introduction to his 

 Historical Sketch (p. 98) states that he has taken the dates of those 

 of Boisduval's works which appeared in "livraisons" from the official 

 literary bulletin published at that time in Paris and that they can be 

 relied on for accuracy; as he gives the date of the genus Xaiithidia 

 as 1829-30 and also mentions the genus Callidryas (which appeared a 

 number of pages later) under the same date we may conclude that 

 the name lisa (Lep. Am. Sept. p. 55) dates at the latest from 1830 and 

 therefore has priority over euterpe Men.
