Is it, too, then a fellow- voyager with the alleged " Viking " Antio2)a ? 

 Is it not possible that, if we had I'ccords extending over a greater 

 period of time, it would be found that the appearances (in numbers) 

 of these irregular insects were in cycles of years ? 



4th. — The fine condition of many of the specimens can only 

 show that they have not "suffered a sea-change." 



5th. — That larvae have not been found does not go far to support 

 either side of the question ; for, though the larvae of many of our 

 common butterflies are so rarely seen, yet, from its habits, I imagine 

 the larva of Antiopa should not be difficult to find.

THE EECENT INVASION BY VANESSA ANTIOPA. 

 BT D. SHARP, M.B. 



I cannot see any way of accounting for the simultaneous appear- 

 ance of numbers of Yanessa Antiojya over the country except by 

 immigration ; but, if this be the case, the insect must possess great 

 power of rapidly distributing itself. 



I once observed a number of the larvae of this species (in the 

 Asturias) feeding on a willow hush, and not near the top. 



I much wish all the evidence as to condition of specimens, &c., 

 could be collected and collated, as the questions involved appear to 

 me of considerable importance. 



If a large portion of the specimens be in good condition, immi- 

 gration would seem doubtful ; while, if the immigration theory be 

 true, some light should be thrown on the question of the locality of 

 their origin, by a knowledge of the facts as to condition of speci- 

 mens. The district where most specimens were found (especially if 

 in good condition), would appear to indicate the point where they 

 landed, at any rate.
