SPILARCTIA, Buikr. 
This genus principally differs from Spilosoma in the greater distance between the emission 
of the first and second median branehes of the primaries, the longer and more deeply fringed 
tegulfe, and generally longer palpi : of the species originally associated under it, S. lativitta 
and S. flavalis of Moore might readily be separated as a distinct genus.
