EUDRYAS. 245 



EUDRYAS HiiBN. 



Wing structure similar to that of the Noctuina. In the hind 

 wings the costal and subcostal veins do not run adjacent and parallel 

 to each other, as is usual amongst the genera of the family, but arise 

 from a short, common stalk. In the fore wings the structure is 

 precisely that of the Noctuina, showing the secondary or subcostal 

 cell, and the subdivision of the nervules characteristic of this group. 



The head is smooth, rather short, with ocelli. The antennae 

 setaceous, minutely ciliated. The labial palpi slightly ascending, 

 but little exceeding the clypeus, smooth, rather thick ; middle and 

 basal joints nearly equal, the terminal minute and ovoid. Tongue 

 rather slender, and about as long as the anterior, coxae. 



Thorax and basal segment of the abdomen tufted. Breast 

 woolly. Abdomen smooth. Legs tufted ; fore legs especially, 

 which have a large globose tarsal tuft, one on the tibiae and one 

 on the coxae. In repose, the fore legs are held in advance.

Fore wings pure white, with a broad stripe along the front edge, 

 extending from the shoulder a little beyond the middle of the edge 

 and a broad band around the outer hind margin, of a deep purple 

 brown color ; the band is edged internally with olive green and 

 marked towards the edge with a slender wavy white line ; near the 

 middle of the wing and touching the brown stripe, are two brown 

 spots, one of them round and the other kidney-shaped ; and on the 

 middle of the inner margin there is a large triangular olive-colored 

 spot ; the under side of the same wings is yellow, and near the 

 middle there is a round and kidney- shaped black spot. The hind 

 wings are yellow above and beneath ; on the upper side with a 

 broad purple-brown hind border, on which there is a little wavy 

 white line, and on the under side with only a central black dot. 

 Head black. Along the middle of the thorax, a broad stripe of 

 black and pearl-colored glittering scales. Shoulder covers white. 

 Upper side of the abdomen is yellow, with a row of black spots on 

 the top, and another on each side; under side and the large muff- 

 like tufts on the fore legs, are white ; other legs, black.
