upper wing till it leaves off where the wing is dilated into the lobe, 

 which gives the wing its hooked-like character ; the lower line is 

 brownish-black, and is straight, except in six places, where the black 

 runs up the nerves triangularly to a point, and meets two of the 

 yellow lobes, which are conjugate."

 Hab. Specimens in the Museum, India House, from N. E. India,

The specimens from xissam, under examination, are identical with 

 those named A. lunula by Mr. Walker, and with others sent from 

 Paris as A. ricini. Some of the references to the preceding species 

 doubtless belong to this. 



Domesticated in Malta, Piedmont, Tripoli, France, and in the Island 

 of Granada. 



The insect known to the Hindoos by the name of Arrindy in some 

 parts, in others Arrundi, appears to be peculiar to the interior parts 

 of Bengal ; and, so far as I can learn, to two districts only, viz. Di- 

 nagepore and Rungpore, where the natives breed and rear it in a 

 domestic state, as they do the common silkworm. The food of the 

 caterpillar consists entirely of the common Ricinus, or Palma Christi, 

 which the natives of these districts call Arrindy (hence the name of 

 the insect), and is abundantly reared over every part of India, on 

 account of the oil obtained from the seed. 



The late Sir William Jones mentions this insect in a letter to Dr. 

 Anderson, dated 17 May, 1 791, under the name of Phalcena ricini : —
