 Cat. 44. 1829. 



Type diibitata L. 



Palpi rather long, .stout, long scaled at base, subascending ; tongue 

 <l(!veloped ; front with scale tuft; antennae of S slightly flattened, 

 tinely ciliate ; thorax tufted posteriorly. Abdomen tufted at end;

Plerocyinia Hiib., Verz. 330, 1818, has dabitata catalogued under 

 it, but the first and more prominent species, cervinata has bipectinate 

 antennne, and taking that as type, the genus becomes a synonym of 

 Xanthorhw Hiib., Verz. 327, 1818.
