This genns agrees with Htimoifoide.'s in many details, such as neuration, anal 

 tnfts, sexual armature, etc. ; but dilfers in the shorter antenna and the normally 

 scaled legs. A comparison of the structure of the two genera leaves no doubt that 

 they are nearer related to each other than to any other genus. 



Clasper long, curved, as in Himantoidea ; tenth segment, har2)e, and penis- 

 sheath different in the three species. 



Larva described by Dyar, see yrotei ; on Chiococca, Rubiaceae, according 

 to Dyar.

The si)ecies of this genus represent each other geographically. Though they 

 agree closely in colour, we keep them specifically separate mainly for the reason to 

 induce lepidopterists who receive material of Cautethia from new localities to 

 study the .specimens closely, and to examine especially the genital armature, instead 

 of putting the individuals simply down as " nocUuformis."

6 ?. Larger than the other species ; yellow area of hindwing rather paler. 



tj. Tenth segment larger than in the other forms (PI. XLIII. f. 33) ; tergite 

 slightly shorter than the sternite in a lateral view (PI. XLIII. f. 34), broader than 

 in yrotei and noctuifovmix, apex strongly convex, apical edge truncate-sinuate with 

 the angle acute ; sternite large, apex divided and hollowed out in a peculiar 

 manner, being divided into three lobes, one mesial and ventral, short, sinuate- 

 truncate, thin, acute in side-view, the other two lobes rounded, incrassate, densely 

 clothed with short spines. Harpe (PI. XLVII. f. 14) triangular, pointed, but not 

 projecting. Penis-sheath with snuill jipical dentate jirocess, jiointing distad.
