seem to affect the coast, although some of the species (C. sub- 

 jectana, Virgaureana, and nubiland) are to be found everywhere 

 throughout these islands. 



The costa in the $ is usually more arcuated than in the d 1 , and 

 in repose the wings are not held in a very deflexed position. 



The larvse, so far as known, are polyphagous, and of sluggish 

 habit. 



This family contains only three genera, which are arranged as 

 follows : 



A. Anterior wings with the costa in the <$ 

 nearly straight) in the $ rounded. 



a. Anterior wings elongate in the $ . 



b. Palpi with the middle joint more than 



twice the length of the apical ... 1. SPHALEROPTEBA . 



B. Anterior wings with the costa slightly ar- 

 cuated in both sexes, but mostly so in the $ . 



b b. Palpi with the middle joint three 



times as long as the apical .... 2. CNEPHASIA. 



C. Anterior wings with the costa slightly, but 

 equally, arcuated in both sexes. 



bbb. Palpi with the middle joint twice 



as long as the apical 3. ABLABIA. 



Genus I. SPHALEROPTERA, GUENEE. 



Palpi longer than the head, remote, ascending ; basal joint stout, 

 elongate, pyriform, truncate ; apical slender, as long as the basal, 

 slightly thickened towards the apex ; middle stout, thickened be- 

 yond the middle, more than twice the length of the apical. Maxilla3 

 stout, as long as the palpi. Maxillary palpi minute, three-jointed ; 

 basal ear-shaped, studded with bristly hairs ; middle and apical both 

 globose. Thorax rather slender, ovate. Anterior wings : length 

 considerably more than twice the width ; the costa in the J nearly 

 straight ; in the $ regularly arcuated ; apical margin in the c? straight, 

 oblique ; in the $ oblique, concave ; dorsal margin nearly straight in 

 both sexes. The costal vein reaches the margin at the middle ; sub- 

 costal nervures not equidistant. The discoidal cell widest at the 

 insertion of the submedian nervure, and scarcely extending two- 

 thirds along the wing. Posterior wings alike in both sexes ; apex 

 obtuse ; apical margin concave ; basal angle produced. Abdomen 

 long, slender in the tf ; stouter iu the $ ; tufted in both sexes. 



Closely allied to the succeeding genus in habit, but offering 

 sufficient structural differences to rank as distinct ; these consist
