aiitlior's P. rhetenor ; and it mimics Moore's P. dasurada^ 

 which occurs with it in the Sikkim, Khasia, andCachar hills. 



Papilio janaha, Moore, exactly copies P. minereus, G. R. 

 Gray, from Sikkim and the adjoining region of Nepal. 



P. bootes, Westwood, presents a similar mimetic resem- 

 blance to the P. polyeuctes of the Khasia hills. 



The interesting and, so far as I have been able to discover, 

 hitherto unrecognized case of mimicry indicated above will 

 be fully described and illustrated in my forthcoming " Notes 

 on the Phenomenon of Mimicry, as exemplified by the 

 Papiiionida3 of our North-eastern Indian Possessions."

Nearly allied to P. ravana, Moore, from Kulu, in the North- 

 west Himalayas, but smaller, with the well-developed tails 

 not constricted at the base. 



^ . Posterior wings above with two large pink-white spots, 

 one between the discoidal vein and the second branch of the 

 subcostal, occupying all but the two ends of the space ; the 

 other in the space next in front, smaller and not extending so 

 far towards the base of the space, and with three bright crim- 

 son submarginal lunules, two subequal in the interspaces 

 between the branches of the median vein, and the third between 

 the third median veinlet and the discoidal vein, equal to, or 

 slightly greater than, the other two taken together ; below 

 with a small pink-white spot between the first branch of the 

 subcostal and the costal veins, forming with the two visible on 

 both sides of the organs a series of three, all equally distinct 

 from the outer margin, the submarginal lunules larger and 

 subequal and much lighter coloured, and with a fourth rather 

 irregularly-shaped crimson spot, subequal to the lunules and 

 divided into two unequal parts by the submediau vein, at tlie 

 end of the basal half of which it is placed, with the tails well 

 developed, but not constricted at base. 



Hah. The vicinity of Silchar, Cachar. The three speci- 

 mens before me were obtained many years ago by one of the 

 native collectors of the museum, under the late J\Ir. N. T. 

 Davey, of the Topographical Survey of India. 



This species will be figured in my paper on the large col- 

 lection of butterflies formed by me during the past hot season 

 in Cachar. 



Ohs. P. ravana and P. minereus are both perfectly distinct 

 from P. philoxcnus, P. polyeuctes being perhaps only a variety 

 of it.
