CosiiwpJiila sabulifera, Guen. Meyr. F. H. i. p. 158. 



Ten specimens, N.W. and S.E. Koolau range, in xA.ugust. Bred from " Hau." 

 In two specimens the subbasal line is slightly marked with black, but quite different in 

 form to noctivolans, being without the very sharp angle (the figure of noctivolans, PI. iv. 

 16, fails to show this, which does in fact sometimes require a lens to make it clear).

One specimen, S.E. Koolau range, Oahu, in July. This is a very striking and 

 distinct species, differing from all described species of the genus by the pectinated 

 antennae. I was at first disposed to think it was an exotic introduction, but cannot find 

 any description that will apply to it ; and I also sent a figure and particulars to Prof 

 J. B. Smith and Sir George Hampson, the two authorities most likely to know it, both
