IQQ [October 



Godart, -n-bo wrote in 1S20, speaks of " la bande jauBatre," and 

 indicates tbe insect as being common near Paris. It would appear, 

 bowever, from bis remarks, tbat spring-cangbt specimens bad wbite 

 borders ; and Berce, writing in 1867, says of tbe biberna,ted speci- 

 mens, tbat tbeir yellow margin bas become wbite, " leur bordure 

 jaune a passe au blanc." 



In Belgium, tbe insect is descinbed as " common in tbe wooded 

 mountains of tbe Ardennes, at Spa, &c. Tolerably rare in tbe gar- 

 dens of tbe otber provinces of tbe country, wbere it is found on fruit 

 trees" (Annales de la Soc. Ent. Beige, I, p. 23) ; and we also read 

 tbere tbat tbe bibernated specimens wbicb appear in April, " ont alors 

 la bande terminale blancbe," implying tbat tbe aiitumual specimens 

 bave yellow borders. 



In Holland, we read in Snellen's ' De Ylinders ran Nederland,' 

 p. 37, tbat tbe border of tbe wings is pale yellow or wbite, " licbtgeel 

 of wit," and tbat tbe insect occurs tbrougbout tbe country, and is 

 everywbere scarce. 



, Linne, in bis ' Fauna Suecica,' speaks in tbe diagnosis of 

 " limbo alhido,'" but in tbe description given be says " margine albo." 

 Zetterstedt, in bis ' Insecta Lapponica,' also uses tbe adjective white 

 to express tbe colour of tbe margins, and mentions tbe insect as no 

 rarity in Lapland, tbougb lo and polycldoros do not extend so far 

 nortb. Wocke, in bis ' Notes on Norwegian Lepidoptera,' says 

 (Stett. ent. Zeit., lS6i, j). 173), "bibernated specimens of Vanessa 

 Antiopa were not scarce at Sigstadt and in Grudbrandsdal," but does 

 not mention tbe colour of tbe margins. 



Tbe dates of tbe occurrence of tbe various specimens bave not 

 been always noticed ; but, from tbose recorded, I collect tbe follow- 

 ing :•— July 26tb ; August 21st, 22nd, 23rd (2), 21tb (8), 25tb (3), 

 20tb (2), 28tb (2), and 29tb ; September 1st, 2nd, 3rd, 7tb, Utb, 

 and 15tb ; tbe numbers in parentbeses representing tbe number of 

 specimens captured or seen wben more tban one. 



It would tbus appear tbat tbe solitary specimen recorded last 

 montb bas no connection witb tbe recent invasion, of wbicb tbe first 

 specimen was noticed on tbe 21st August, tbe maximum was attained 

 on tbe 2-ltb, and tben tbe specimens seem sj^eedily to diminisb in tbe 

 early days of September. 



One tbeory is, tbat tbe specimens are already bibernatiug ; but 

 we are perbaps bardly sufficiently acquainted witb the babits of tbe 

 insect to say wbetber, like polychJoros, it bibernates early, or wbotber,
