joints. These are transverse, about of equal length ; the fifth joint is rather longer than the 

 preceding, tapering, terminated by a mucro representing the claw. 

 Middle and Posterior Legs with the tibia? rather shorter than the femora, spiny ; the spurs long. 

 Tarsi rather longer than the tibia?, spiny both above and below ; the spines at the sides and 

 below nearly in regular series. First joint as long as the rest combined; rest, to the fourth, 

 progressively shorter ; fifth rather longer than the third. Claws curved, very slightly grooved 

 below. Paronychia bilaciniate ; the outer lacinia elongate, somewhat elliptical, equal to the 

 claw; inner rather strap-shaped, short. Pulvillus jointed, as long as the claw; the second joint 

 very broad. 

 Abdomen about two thirds the length of the inner margin of the posterior wings. 



Larva and Pupa unknown. 



The rare and beautiful insect which alone composes this genus is at once distinguished from its allies by its peculiar 

 colour. The rich black of its upper surface, glossed with the most intense blue, and the curious velvety patch of hair 

 on both wings of the males, seem to indicate but little affinity to the typical Argynnina. We have, however, the first 

 appearance of this blue colour in the tint visible in certain lights on the wings of Lachnoptera Iole ; and the males of that 

 insect have likewise a large patch of hair on the posterior wings. Again, in the males of Argynuis Paphia we have the 

 median nervule clothed with hairs, as in some species of Papilio. By its palpi, antenna?, and the neuration of its wings, 

 Terinos evidently belongs to the group composing the genus Argynnis of Godart; and the little patch of orange at the 

 anal angle of the posterior wing, as well as the markings of the under surface, are additional evidences of this. It is 

 remarkable, however, for having the eyes covered with hair, which at once distinguishes it from its allies. 



As far as my knowledge extends, this insect is confined to the Indian archipelago and the peninsula of Malacca. 

 The specimen figured was captured at Sarawak, by my friend, Mr. Hugh Low, who informs me that in its flight ami 

 habits it resembles our Argynnis Paphia.
