Asiatic Silk-producing Moths. 315 



Bomhyx Bengalensis, Hiitton. 



A wild species discovered by A. Grote, Esq., feeding upon the 

 Artocarpus Lacoocha in the neighbourhood of Calcutta, where it is 

 scarce. The larva spined, like that of B. Huttoni. 



Bomhyx Horsjieldi, Moore, Catal. Lep. Mus. India House, 



ii. p. S80, plate 11a, fig. 5 (1858). 

 Inhabits Java, where discovered by the late Dr. Horsfield. 



Bomhyx suhnotala, Walker, Proc. Linn. Soc. (Zool.) iii. p. 188 

 (1859). 



Described as from Singapore, where it was collected by Mr. 

 A. R. Wallace. 



Remark. — The last five species, namely, B. religiosce, Huttoni, 

 Bengalensis, Horsjieldi and subnotata, might, with propriety, be 

 separated from the genus Bomhyx under the name Theophila, 

 nobis, — there being well-defined differential characters both in the 

 larva and imago. 



Ocinara dilectula, Walker, Catal. Lep. B. M. pt. vii. p. 1 768 

 (1856). 



Inhabits Java. 



The larva and cocoon of this are figured on plate xviii,, fig. 6, 6 a, 

 of the Catal. Lep. Mus. Ind. House. Feeds on a species of Ficus. 



Remark. — Captain Hutton, in a letter just received, states that 

 he has lately discovered three other species of this genus. 



Attacus Atlas, Linn., Cramer, Pap. Exot. iv. pi. 381, f. C. 382, 

 f. A. 



Inhabits China, Burmah, India, Ceylon and Java, specimens 

 from all which countries are identical, except in depth of colouring 

 and in the talcose spots of the fore-wing varying in size, and in the 

 presence or not of the small upper spot. In the hind-wing the mar- 

 ginal chain-like markings in some specimens are black, in others 

 ferruginous, this occurring in specimens from the same localities. 



The larva feeds on Falconeria insignis and Bradteia ovala, and 

 spins the cocoon within the leaf, and, when mature, is of a pale 

 sea-green, thickly covered over with a white powder, which is 

 evidently secreted from the long fleshy tubercles which arise in 

 rows down the length of the body. It is easily reared in a state 

 of domestication, producing a cocoon well stored with a fine, yet 

 strong, silk of a greyish colour. 



The Tusseh cloth of China is said to be produced from this.
