Evidently tliis is related to pteryloia from its bipectinate an- 

 tennae and general pattern of wings. It may prove to l)e the 

 female of that species. Dr. Perkins informs me that Hampson 

 so considered some female Plusias collected by him at Kilaiiea 

 sevei-al years ago. However, my specimens differ very much in 

 general coloration from Meyrick's (lescri])ti(m of pteyylota. and 

 in the color and shape of the metallic spots in the disc.
