Remarks. — Somewhat similar to symplacota Meyrick and with a 

 cornutus almost of the same shape. Differs in having the genitalic 

 characters of the subgenus Eurynatteria and in some details of the 

 markings of the wings. The latter vary a little in the confluence of the 

 apical and terminal streaks of the forewing and the development of 

 spots in the internal areas of both wmgs; the extreme form with nu- 

 merous discal spots received a separate name baccheutis Meyrick 

 The hindwing of male is suffused with yellowish olive and usually has 

 the subdorsal spots larger and more numerous.

Remarks. — Meyrick described baccheutis as a separate species on the 

 basis of two specimens, one of which was the present lectotype, and 

 the other a male which is now missing. The photographs in plate 40 

 give a clear idea of baccheutis as a form very close to heliocausta. The 

 only important difference between them is in the discal and dorsal 

 spots, well developed in baccheutis and only slightly (and not always) 

 indicated in heliocausta. The discal dots of the hindwing show a 

 similar arrangement in both, although they also are better developed 

 and more numerous in baccheutis. There is no difference in the female 

 genitaha of both, and this is the reason for treating baccheutis and 

 heliocausta as conspecific. It is quite possible that baccheutis, originat-
