Genus I LIBYTHEA 



LiBYTHEA Fahricius, Syst. Gloss. ; Latreille, ifc, 

 IIecaerge Iliilmer. 



Body rolmst, thickly clothed with soft woolly hairs, rather small in size, and of dark colours ; the wings with spots of 



orange, or dirty white, but not ocellated. 

 Head small, strongly tufted in front. 



Eyes prominent, naked. 



Labial Palpi extraordinarily elongated, being one third, or even in some species half, the length of the whole 

 body; porrected horizontally, not compressed, thickly clothed with hairs of moderate length, the inner edges 

 uniting together, so as to form conjointly a long conical beak, obtuse at the tip; second joint oval; third joint 

 greatly elongated and slender. 



Antennce not nearly half the length of the fore wings, straight, articulations indistinct, gradually thickening from 

 tlic base to the tip, which is obtuse. 

 Thorax oval, hairy ; tippets strongly developed. 



Fore ]]'in(].'< of moderate size. Costal margin moderately arched ; apex acute. Apical margin strongly angu- 

 lated below the apex ; the lower discoidal vein extending into the most prominent part of the angle, about live 

 sixths of the length of the costal margin. Inner margin straight, one fourth longer than the apical margin. 

 None of the veins dilated at the base. Costal vein extending to about half the length of the costa. Postcostal 

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

 bi-anch arising far beyond the cell, followed at a short distance by the fourth, which extends to the tip of the 

 wing. Upper disco-cellular vein very minute and sub-oblique ; middle and lower ones of nearly equal length, 

 very slender, and uniting into a curve, closing the discoidal cell about the middle of the wing, by uniting with 

 the third branch of the median vein at about the same distance from its base as exists between the first and 

 second branches.
