Dio ariou-Kaupeu können jedoch nicht von den 

 Ameisen gefüttert werden, sondern nur von 

 dem vegetabilischen Abfall (?) etc. im Neste 

 leben. 



Warum ist es so schwierig, die arion-Raupeu 

 zu finden ? Die Falter sind im nördlichen Corn- 

 wallis so zahlreich, dass man annehmen muss, 

 auch die Raupen seien häufig. Nach Frohawks 

 Darstellung soll es aber nicht der Fall sein. 

 Besitzt die ariou-Raupe etwa eine besondere 

 Fähigkeit, sich zu verbergen ?

 North American Species. 



Telea pohjphemus. — The moths of this species 

 emerged in 1!»03, from the 23rd of May to the 25th 

 of June; in 1904 they emerged from the 18th of 

 May, more than a month earlier, in consequence of 

 the unusually warm weather we have had this season. 

 However in 1903, three pairings of jjoZj/jj/iOHits were 

 obtained, and the rearing of the worms was very suc- 

 cessful in the open air on small oak trees in my garden ; 

 in 1904 on the contrary, no pairings could be obtained. 

 This species, as it has been previously stated, pairing 

 with the greatest difficulty in captivity. The cocoons 

 received this year were for the most part very small, 

 and the result, owing to these two causes, was a 

 total failure. A fact came to my notice, which, I 

 think, deserves to be recorded; a cocoon of the 

 rearing of 1903, which had been overlooked and left 

 all the winter, spring and summer, in the garden, 

 produced a male moth, which emerged on the 4th 

 August, forty-six days after the emergence of the 

 last American iwhjphemus, in the same year 1904, 

 warm as the season had been. This fact tends to 

 show that if the cocoons were left in the open air, 

 it would be impossible to rear the species so late 

 in the season, and, therefore, that it could not be 

 acclimatised in England, even under the most favou- 

 rable conditions. 



Actias luna. — With a very large ([uantity of 

 cocoons, only one pairing was obtained, which was 

 on the early morning of the 1 4th of June. Most of 

 the eggs from that single pairing were bad, and the 

 larviv which hatched on the 1st July died within a 

 few days. The cocoons which had been sent to me 

 were very small, and had the appearance of being 

 he product of worms carelessly bred and perhaps 



kept short of good fresh foliage. The moths emerged 

 from the 27th of April to the 13th of June. On the 

 Ist of August I received twenty -three fine luna co- 

 coons, of the second brood, from Brooklyn ; thirteen 

 moths had emerged during the voyage, and two of 

 the cocoons had died. From the eight remaining 

 cocoons, excepting one, all the moths were large and 

 line, and three pairings were obtained, one male 

 having paired twice, a very different result from the 

 one I had with the first cocoons sent. The moths 

 began to emerge on the 1st of August, the same 

 day the box of cocoons had arrived, and they con- 

 tinued to emerge up to the 6th of the same month. 

 The first pairing took place on the 3rd, the second 

 on the 5th, and the third on the 7th August. The 

 first larva; hatched on the 13th and 14th of August, 

 they commenced spinning their cocoons from the 

 28th of September and continued till the 18th of 

 October, when they all were in cocoons. The larvae 

 bred in captivity in the house, thrived remarkably 

 well on walnut leaves, and there was no case of 

 fatality. The cocoons obtained are very fine, and 

 much larger than the first I had received from 

 America. to he continued.
