 Shanghai. 



Walker's measurement of this species is entirely incorrect ; the " black point " on each 

 side of the thorax, mentioned in his description, is due to abrasion. 



SPILARCTIA, Butler. 



This genus principally differs from Spilosoma in the greater distance between the emission 

 of the first and second median branches of the primaries, the longer and more deeply fringed 

 tegulje, 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.
