Genus XXXVI. EUNOGYRA Westwood. 



Body rather slender ; wings large, rounded, obscurely coloured with a submarginal row of confluent ocelli. 

 Head small, rounded, clothed with very fine hairs. 



Eyes prominent, naked. 



Antenna; short, slender; joints moderately distinct, slightly ringed witli white; terminated by a small but distinct 

 club, with the tip rather acute and slightly incurved. 



Labial Palpi very minute, much curved, compressed, applied close to the face, not reaching higher than one 

 fourth of the eyes, and not visible beyond tlie hairs of the face from above, finely hairy beneath ; terminal joint 

 very minute, scarcely distinct. 

 Thorax small, finely hairy. 



Fore Wings large. Costal margin regularly arched ; apical angle rounded. Ajiical margin convex, entire ; 

 hinder angle rounded. Inner margin straight, long. Costal vein short, not extending to the middle of the 

 costa ; near the tip it throws off a short branch, which runs obliquely (in the direction of the upper discoidal 

 vein) and joins the first branch of the postcostal vein close to its origin. Postcostal vein with four brandies ; 

 the first and second arising before the anterior extremity of the discoidal cell, the third at about three fourths, 

 and the fifth at about five sixths, of the length of the wing ; the terminal part of the postcostal vein e.xtendino- 

 to the tip of the wing. Upper disco-cellular vein obsolete : the middle one arising simultaneously with the 

 upper discoidal, at a small distance beyond the extremity of the discoidal cell : the middle and lower disco- 

 cellular veins uniting to form a strong arch, by uniting witli the third bi-anch of the median vein at a short 

 distance beyond its origin. 



m7id Wrngs subovate-trigonate. Costal margin slightly curved. Apical margin strongly rounded. Costal vein 

 scarcely extending beyond one fourth of the length of the costa. Precostal arched, finely attenuated. Post- 

 costal arising opposite to the precostal, branching at about one third of the length of the wing, its branch 

 joining to the costa at about two tliirds of its length, the remainder of the postcostal itself reacliing to the 

 outer angle of the wing. Upper disco-cellular arismg at a very short distance beyond the branch of the 

 postcostal, slender, oblique : lower disco-cellular longer, rather less oblique, uniting with the third branch of 

 the median vein at about the same distance beyond the origin of the latter as exists between the first and 

 second branches, closing the discoidal cell in an acute point. 



Fore Legs of the male extremely short, rather thick, and clothed with very sliort scaly hairs. 



Fore Legs of the female ? 



Four Hind Legs rather short, scaly. Tarsi rather thick ; the four terminal joints equally short. Ungues and 

 appendages minute. 



I have been corapelleJ to iustitutc another new genus for the reception of a dull-coloured species of small size, liaving much the 

 appearance of some of the Satyrida?, differing from all of the preceding genera in the arrangement of the veins of its wings, as well as 

 partially so in various other characters. I have hitherto nowhere else observed the branching of the costal vein described above, and 

 it is only in very few of the species of this family, chiefly the earlier-described genera, that a four-branched postcostal vein occurs. 

 Having examined several specimens, I am able to state that the peculiar veining described above is a constant character. Its style of 

 marking is also quite unlike that of any other species in the family.
