Warren differentiates this genus from Xanthorhoe by the eharaeter of the pal])us. whieli is elongate 

 and very heavily tufted beneath, the face-eone likewise elongate. The bent termen of the hindw ing gives it a 

 somewhat distinctive faeies. But as both palpus and wing-form show a good deal of Variation in Xanthorhoe. 

 it would not be difficult to inelude it therein as a seetion. especially as only one sj)eeies is known. so that it 

 does not provide any further groujiing.

(See Suppl. Vdl. 4. p. 120; Vol. lii. p. Sii.) 



This genus was founded on the ubiquitous obstipata F.. luider the synonym of "hrnnneipennis -sp. n.". 

 whieh differs from Xanthorhoe and Orthonama in that the 3rd radial and Ist median of the hindwing are almost 

 always stalked, never well separate at their origin. Further distiiu^tions are fomid in the nafure of the sexual 

 dimorphism. in the genitalia and in the sinuons termen of the hindwing. Antenna of j with paired faseieles
