SYRMATIA. ANTEROS. 



427 



Genus X. ANTEROS 



Anteros Hiibner, Vei'zeichniss ; E. Doubleday. 



Chrysilis Boisduval. 



Erycina and Polyojoiatus ^. God'. 



Body small : wings above generally brownish black, with one or more whitish patches ; beneath richly ornamented with 



metallic spots : legs tufted. 

 Head small, slightly tufted on the crown. 



Eyes large, lateral, finely hairy. 



Labial Palpi very small, compressed, porrected nearly horizontally, the tip not extending beyond the hairs of the 

 face, clothed beneath with fine rather long hairs, the tip rather acute. 



Antennae rather long, very slender, with the joints in the middle elongated, and annulated with white ; termi- 

 nated by an elongated distinct club, attenuated at its base, and terminated by an acute curved point. 

 Thorax rather robust. 



Fore Wings broadly ovate-subtriangular. Costa arched. Apical angle obtuse. Apical margin convex, entire, 

 two thirds of the length of the costa. Inner margin straight, rather longer than the apical one. Postcostal 

 vein with the first and second branches arising before the anterior extremity of the discoidal cell ; third branch 

 arising about half way between the end of the cell and the tip of the wing. Upper disco-cellular vein obsolete : 

 middle one arising about as far beyond the second branch of the postcostal vein as exists between the first and 

 second branches, transverse, and directed rather obliquely towards the base of the wing, short, slender: lower 

 disco-cellular vein longer than the middle one, following its direction, equally slender, and uniting with the 

 median vein exactly at the origin of the third branch. Upper discoidal vein arising exactly at the point of 

 origin of the middle disco-cellular, and following the direction of the base of the postcostal vein, of which it 

 might be considered as the terminal portion. 



Hind Wings subovate, arched along the costa. The outer margin more or less scalloped. The anal angle, and 

 one or two of the adjacent prominent points between the scallops, producing very long squaraose seta;, those 

 of the anal angle being the longest. Costal vein extending rather beyond the middle of the costa. Precostal 

 vein arising exactly opposite the postcostal, oblique. Postcostal branching at a considerable distance from the 

 base, the branch scarcely extending to the outer angle. Upper disco-cellular very slender, transverse, arising 

 at a little distance beyond the branch of the postcostal vein, short. Lower disco-cellular also very slender, 

 transverse, uniting with the median vein exactly at the origin of its third branch. The submedian vein 

 extending into the elongated anal angle. 



Legs very much tufted in both sexes. 



Fore Legs of the male very small, forming a dense brush from the base of the tibia to the tip of the tarsus. 

 Femur very short. Fare Legs of the female rather longer. Femur, tibia, and basal joint of the tarsus clothed 

 with long hairs. Terminal joints of the tarsus short, distinct, and scaly. 



Four Hind Legs slender, but densely clothed with long hairs along the femur and tibia. Tarsus with the basal 

 joint furnished with a tuft of long scaly hairs on the outside, set on obliquely. Terminal joints short, 

 thick. 

 Abdomen rather elongated. 



The little butterflies forming this genus are among the most brilliant of the insect tribe, although, if the upper surface of their wings 

 be alone regarded, no one would conceive it possible that so much beauty existed in the group. Here, however, we find the richest 

 velvety patches of colour, bearing spots of burnished gold and silver, or variegated with lines of greenish or bluish metallic tints, 

 rending it difficult to describe, or even to delineate, some of the species. The curious tufts of hair-like scales at the anal angle of the 

 hind wings, together with the short tufted legs, afford the best characters of the group, which is very closely allied to the second 

 section, or subgenus, of Helicopis. It may, indeed, be questioned whether H. Dematria and Chrysus ought not more properly to be 

 considered as a subgenus of Anteros ; agreeing therewith in the dull colours of the upper surface of the wings, the arrangement of the 

 wing veins, and the structure of the antennje and legs, but differing in the hind wings being furnished with long tails.
