This genus agrees with Uiinantoides in many details, such as neuration, anal 

 tufts, sexnal armature, etc. ; but difiers 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 Hhnanfoidcs ; tenth segment, harpe, and peiiis- 

 sheath difierent in the three species.

The species of this genus represent each otiier geographically. Though they 

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

 induce lepidopterists who receive material of Cantethia from new localities to 

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

 of putting the individuals simply down as " noctiii/ormis."
