Genus I. LOBESIA, GUENEE. 



Palpi longer than the head, porrected horizontally, remote, di- 

 verging; basal joint stout, curved, isometric, truncate, drooping; 

 apical slender, obovate, slightly longer than the basal, horizontal ; 

 middle ascending, curved, thickest beyond the middle, more than 

 three times the length of the apical. Maxillae slender, longer than 

 the palpi. Thorax robust, ovate, with a small tuft or crest behind. 

 Anterior wings : in length considerably more than twice the width ; 

 costa slightly arcuated; apex acute; apical margin very oblique, 

 nearly straight; dorsal margin rounded. The costal vein reaches 

 the margin beyond the middle ; subcostal nervures not equidistant. 

 The discoidal cell is situated on the upper half of the wing, extends 

 nearly two-thirds its length, and widest at its apex. Posterior 

 wings elongate ; apex obtuse, produced ; apical margin very oblique 

 and straight in the tf , concave in the $ ; basal angle produced. 

 Abdomen long and slender in the tf , stouter and shorter in the $ ; 

 a small tuft at the apex in both sexes. 



This genus contains but one British species. In the acute, 

 triangular shape of the anterior wings, it resembles Mixodia ; 

 but the singularly-shaped posterior wings in the d, and the 

 differently- shaped ones in the $ (independent of the disparity in 

 the colouring of these organs), not only remove it from that, but 

 from any other British genus. The larva is unknown.
