Asiatic Silk-producing Moths. 319 



of oak. (The leaf figured, with its attached cocoon, by Guer.- 

 Meneville, is that of Castanea Japonica.) 



May be distinguished by the band on the hind-wing being con- 

 tiguous to the ocellus. 



The cocoon is somewhat like that of the Tussur, but diflTers in 

 having an exterior coating of loose silk. 



Anthercea Yamamai, Guer.-Menev., Rev. et Mag. de Zool. 1861, 

 pi. 11, 12 and 13. 



Inhabits Yamamai, in Japan. 



The cocoon and silk are pale yellowish-green. Samples are 

 shown among the raw products in the Japan Court of the Inter- 

 national Exhibition. 



Anthercea Roylei, Moore, Proc. Zool. Soc. Lond. 1859, pi. 64, 

 f. 1. 



This is a common species both at Simla, Mussooree and 

 Almorah. 



Capt. Hutton informs me that the larva feeds upon the hill 

 oak (Quercus incana). He has lately had it under cultivation and 

 the silk is pronounced to be promising and worth cultivating. 

 They can be reared easily in the house. 



Capt. Hutton effected a cross between this and Anth. Paphia, by 

 placing the females of the latter out upon a bush at night. In 

 the morning a male A. Roylei was found coupled with them. In 

 this way were obtained three batches of eggs, but out of about 

 600 eggs only fifty hatched. The worms went on very well until 

 the first moult and then all died but two, they were unable to cast 

 their skins. " It is remarkable, however," he continues, " that a 

 female A. Roylei in my study window was ravished by a male 

 A. Paphia, which came at night out of a cocoon suspended there 

 also. I say ravished, because during the whole day the female 

 made violent efforts to disengage herself, but in vain ; she appeared 

 to be in pain from the operation. In the evening they separated 

 and the female, instead of depositing her ova, died {from a surfeit 

 of love, I imagine). I took the eggs from her body, but none 

 hatched." 



Capt. Boys mentions this as also occurring in Kemaon. 



Anthercea Perrotletii (Guer.-Meneville), Mag. de Zool. 1843, 



pi. 123. 

 Inhabits Pondicherry, and is probably the variety of the Tussur 

 mentioned above, as having four broods in the year.
