female. Thorax, as usual, proportionally well developed, the disc 

 globose ; above, entirely brilliant metallic greenish blue ; tegulae, 

 fringed with longer and duller hairs. The metallic color of the 

 thoracic parts extends over basal abdominal segment above. 

 Beneath, the thoracic parts are entirely fulvous ; the rather long 

 and slender, cyaneous-black legs are covered with fulvous scales. 

 Abdomen, rather slender and weak, not exceeding internal margin 

 of secondaries in length, entirely fulvous; beneath, of a more yel- 

 low, less orange shade. The abdominal squamation is mealy and 

 characteristic of the genus. The genital claspers, in the male, are 

 fringed with longer hairs ; in the female, the abdomen terminates 

 more pointedly. 



The wings are rather long and large ; anterior wings well pro- 

 duced apically, above of a brilliant metallic greenish blue color 

 with a changeable reflection, without markings. Along external 

 margin, the metallic coloration becomes obsolete, leaving a narrow, 

 even, terminal space of a dull black hue. The " veins " are obso- 

 letely brought into relief by darker scales ; fringes, blackish. 



Posterior w r ings, rounded, of a dull black color, shaded medially 

 with deep blue ; the median and internal nervules are accompanied 

 by diffuse, bright greenish blue shades extending from the base of 

 the wing and becoming obsolete outwardly. 



Under surface of both wings, resembling upper ; the primaries 

 are dull blackish along internal margin, and less brilliant than on 

 their upper surface ; the secondaries are more largely shaded with 

 bright greenish blue, and are consequently more brilliantly colored 

 than on the upper surface. 



Expanse, $ and £ , 1.45 inch. Length of body, 0.50 inch.

Although this brilliantly colored species is strongly con-

 separation. The typical metallic coloration of the Family is
