moderately long. Aedeagus moderately long, tubular, narrowed and 

 pointed ventroapically, with a long, obliquely located orificium 

 dorsoapically; coecum penis curved downward, slightly tapering to 

 bottom, ending with a narrow process, or without such a process; 

 cornuti flat, rather long, narrowed at base and apically, and lying 

 over one other. 



Female genitalia. — Papillae anales pelmiform, oblong, soft, and 

 haired. Sinus vaginalis infundibidar or somewhat tureen shaped, 

 cephalically rounded or flat. Lamella antevaginalis narrow, en- 

 circling sinus vaginalis cephalically; lamella postvaginalis composed 

 of two triangular pieces located caudolaterad of ostium bursa and 

 connected to dorsal, membranous wall of sinus vaginalis. Antrum 

 short, tubular, membranous or sKghtly sclerotized, bearing two nar- 

 row, lateral coUicule; ductus bursa rather short; bursa copulatrix 

 membranous; cervix bursae variously long and broad, but generally 

 moderate; corpus bursa rotundate or slightly elongate, smooth or 

 somewhat rugose; signum strongly sclerotized, with a basal plate 

 elevated over external surface of corpus bursa, narrowly extended 

 caudad and cephalad, and having a variously pronounced capitulum ; 

 internal process of signum dagger shaped, straight or curved. 



Remarks. — In spite of its very distinct appearance, Idolatteria is 

 morphologically very close to the genus Argyrotaenia Stephens, having 

 similar wing venation and very similar genitalia. The genitahc re- 

 semblance of these two genera is so complete, even in details, that it 

 is impossible to separate one genus from the other, using only these 

 characters. The external distinction consists of very long labial palpi 

 of Idolatteria and the bright coloring of the wings and the body of the 

 moths of this genus. Also the pattern of the wings is completely 

 distinct in both Idolatteria and Argyrotaenia. The labial palpi of 

 Idolatteria further differ from those of Argyrotaenia in having a taper- 

 ing, subacute terminal segment which in the latter genus is more 

 cylindrical and blunt.
