 scales, but with a slender pouch and tuft near end of 

 submedian nervure.

 tomosed as in Discophora. Male with a tuft of erectile 

 hairs at base oi subcostal nervure on upperside of hindwing.

XLI. — Clerome. 



Genus 33.— XAITTHOT^NIA, Westwood. 



Clerome subgenus Xanthotcenia, Westwood, Trans. Ent. Soc. Lond., new series, vol. iv, p. 187 (1856I. 



Separated from Clerome with the following remarks : "In the shortness and roundness of 

 the forewing, and in the upperside behig destitute of ocelli, this insect agrees with the genus 

 Clerome ; but differs in the broad oblique yellow fascia and subapical white spot of the forewing, 

 as well as the more elongated form [in breadth] of the hindwing ; and the insertion of the 

 second branch of the subcostal nervure [of the forewing] at a [comparatively] short distance 

 beyond the extremity of the discoidal eel!, (opposite to the extremity of the costal nervure, which 

 only reaches to the middle of the costa,) the third and fourth branches of the subcostal nervure 

 of the forewing rise a moderate distance apart ; the lower disco-cellular nervule of the forewing 

 (closing the discoidal cell), although oblique, is nearly straight. The palpi are much com- 

 pressed, of moderate size, thickly clothed with close appressed hairs, the terminal joint dis- 

 tinct, slender, acute at the tip, and raised to the level of the top of the crown of the head. 

 The antennce are long, gradually but slightly clavate, the tip a little curved and acute ; they 

 are brown, the outer half ferruginous. From all these characters I have no hesitation in 

 regarding this insect as a distinct subgenus, to which I have applied the name XanthoUsnia, 

 in allusion to the yellow fascia of the forewing." {IVcstwood^ 1, c.)
