AMERICAN LEPIDOPTERA. 287 



33. TRIPHOSA Steph. 

 Cat. 44, 1829. 



Type dnhitata L. 



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

 developed ; front with scale tuft ; antennae of % slightly flattened, 

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

 hind tibiae with two pairs of spurs ; fore wings two accessory cells, 

 12 veins; hind wings 8 veins, 6 and 7 stemmed, 8 with cell to be- 

 yond middle, outer margin of wings scalloped. 



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

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

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

 Xanthorhce Hiib., Verz. 327, 1818.

Palpi moderate, or quite long ; tongue developed ; front smooth, 

 .sometimes flat, sometimes rounded and protuberant ; antennae of %

 tufted ; fore tibiae unarmed ; hind tibiae with all spurs ; fore wings

A genus as here limited with considerable variation in structure. 

 The species agree, however, in the flattened antennae of the S .
