Type of genus. — ThanatojJsyche canescens Butler, 1882. Mono- 

 basic. 



Male. — Body densely clothed with long hair. Antennae (fig. 

 379) bipectinate, pectinations gradually decreasing in length to apex; 

 sensory hairs relatively short, stout, equalling or slightly exceeding 

 diameter of pectinations in length, uniformly spaced in definite rows. 

 Foretibia (fig. 182) without epiphysis; mid- and hindtibiae each with 

 an apical spur. 



Wings (fig. 164) more or less transparent with sparsely scattered 

 scales, most heavily concentrated along veins causing latter to stand 

 out prominently. Forewing 12-veined; discal scales usually narrowly 

 oblanccolate, truncate apices or nearly so; R3 and 4 stalked, R5 usually 

 connate at base; in rare instances Ri and 2 stalked or Ro stalked along 

 with R3 and 4; Mj arising from cell much nearer R5 than M2 + 3; 

 M2 and 3 always stalked; base of M variable, branched or unbranched 

 within cell of fore- and hind wings; lA curved downward, fusing with 

 2A ^^ distance along hindmargin; 2A and 3A joined near wing base, 

 3A completely fused, not continued as spur. Secondaries 8-veined, 

 Sc+Ri and Rs usually joined at base, separated along most of cell, 

 joining again just beyond apex of cell, finally separating as Sc + Ri 

 and Rs before reaching outer margin of wing; M2 stalked with M3 

 in all specimens examined. 



Male genitalia. — Apex of tegumen acute. Valves with pulvilli 

 moderately developed; apex of sacculus minutely toothed; posterior
