in China, but only of the common sort. It will gratify curiosity, if not prove advan- 

 tageous, should future observers ascertain what kind of insects the Chinese appropriate 

 to making silk, and whether P. Atlas is of the number, as has been conjectured. It is 

 indeed to be observed, that in India several distinct species of Saturnia are known to be 

 employed in the production of silk ; the most important of which are the Tusseh (S. 

 Paphia, Linn.), the Arrindi (S. Cynthia, Drury), and the Kolisurra silk worm of the 

 Dukhun.*

The natural situation of this and some other allied insects is doubtful ; it forms the 

 type of Mr. Swainson's group Heleona, but is considered by that author to belong to the 

 tribe of Sphingides, and family of Zyggeidse (Anthoceridae, Swainson).
