" The silk may be reeled the same as that of the Mulberry 

 worms. The moth emerges about the end of August."

 feeding Silkworm from Japan, published in the Transactions 

 of the Entom. Soc. 3rd series, vol. v. pt. 5; Dr. Ward's

Anthercea Pernyiy producing a very valuable silk, is an 

 oak feeder, a denizen of the mountainous districts in the 

 neighbourhood of Newchwang, North China, one of the 

 ports recently opened to our commerce. The cold in winter 

 is so severe, that, as in the Baltic, the Gulf of Leotang is 

 frozen up, and all coqamunication interrupted. But one 

 importation of the cocoons of this species into Great Britain 

 has hitherto been made — in 1867. This succeeded so far 

 only as to manifest the probability of acclimatizing the race. 

 Several cocoons were reared of the second generation, but 

 not sufficient to perpetuate the race. 



An account of this insect, with a plate, may be found in 

 the ''Intellectual Observer," for May, 1867. M. Gelot 

 thus speaks in its favour: — "The silk of this species is 

 remarkably good : fine, stiong and lustrous. It nearly equals 

 that of the Yama-Mai. The cocoons, when properly pre- 

 pared, are reeled easily, with but little waste. Its natural 

 yellow-grey tint is no obstacle to the dyer, in proof of which 

 I exhibit seven species of this silk in various colours. The 

 beauty of this silk renders it of great value for acclima- 

 tization in our country." 



Some of the cocoons imported in 1867 were entrusted to me. 

 The moths emerged at various dates in the spring, copu- 

 lated readily, and laid large eggs of a chocolate brown, some-
