Genus IV. OGYRIS. 



Ogyris E. Douhleday, List Lep. B. M. pt. ii. 



Body small, but rather robust : Avings large, scalloped along the outer margins. 



Head moderate-sized, finely hairy, scarcely tufted in front, or on the crown. 



Lahial Palpi porrected in front of the face to about the length of the head, and ascending obliquely to the level 

 of the top of the ej'es, slender, compressed, and narrowed, finely scaly ; the middle joint elongate, and nearly 

 straight ; the terminal joint minute, oval, and nearly naked. 

 Antennce rather short, slender; terminated by an elongate, gradually formed, not very robust club, rather 

 obliquely obtuse at the tip. 



Thorax. Fore Wings large and wide, much arched along the costal margin, subacute at the apical angle. Apical margin 

 scalloped, rather convex. Inner margin elongated. Costal vein short. Postcostal with two branches arising 

 before the anterior extremity of the discoidal cell, slightly angulated at a short distance beyond the second 

 branch, and emitting a third branch about half-way between the cell and the tip of the wing. Upper disco- 

 cellular vein obsolete ; the upper discoidal vein arising conjointly with the middle disco-cellular at the slight 

 angulation of the postcostal vein : middle disco-cellular vein transverse, of equal length with the lower one, 

 which is also transverse, but together forming a slight curve : the lower one uniting with the third branch of 

 the median vein at a moderate distance beyond its origin, this third branch being angulated at the place of 

 junction. 

 Ilind Wings broadly ovate, scalloped along the outer margin ; not tailed. Precostal vein obsolete. Costal vein 

 extending to the outer anjrle of the wino-g. Postcostal vein branchinar at a moderate distance from the base. 

 Upper disco-cellular vein arising at a rather considerable distance be}'ond the branch of the postcostal, very 

 much arched, the inner part forming the base of the discoidal vein : lower disco-cellular very slender, straight, 

 transverse, uniting with the third branch of the median vein at a short distance beyond its origin. 

 Fore Legs in both sexes clothed with very long scales. Femur haiiy beneath. Tibia of the males as long as the 

 femur, that of the female shorfer. Fore tarsus in the male slender, consisting of a long single joint, finely 

 spined beneath ; that of the female as long as the tibia, five-jointed, the joints spined at the tip beneath ; fifth 

 joint longer than the preceding, with two short bent ungues. 

 Four Hind Legs moderately elongated, scaly. Tibial spurs short. Tarsi spined beneath, especially at the tips 

 of the joints. Ungues porrected, but small, very much curved, simple, and acute at the tips. Pulvillus 

 small, somewhat heart-shaped, thickened at the sides. Pseudonychia small, subtriangular, finely villose. 



This genus consists of two Australian species of great rarity, distinguished by the dissimilarity in the sexes, and by the scalloped 

 margins of the wings, as well as the strongly scaled fore legs. Tlic postcostal vein of the fore wings has also only three branches, and the 

 upper disco-cellular vein of the hind wings is veiy much arched. The insect figured in our Plate LXXV. is a female, the opposite 

 sex, which was regarded by I\Ir. E. Doubleday as a distinct species (O. Damo), being smaller, and entirely of a bluish black colour on 

 the upper side of the wings. The under side of the wings in both sexes is of an obscure dull greyish brown, with numerous irregular 

 waved darker bands, eacli edged with a still darker line.
