Lepidoptera from the Hawaiian Islands. 35 



external borders ; primaries with iridescent greyish ia- 

 ternal area ; a large spot in the cell, a still larger one 

 at the end of the cell, and an inverted falciform discal 

 line black ; apical half of costal border white spotted 

 with black ; secondaries with a dot in the cell, a spot at 

 the upper angle of the cell, a still larger spot at the pro- 

 jecting lower angle, and a subconfluent discal sinuous 

 series of unequal spots black ; body below white ; legs 

 banded with black. Expanse of wings 23 mm. 



The smallest species yet described ; it has the usual 

 characteristic indentation of the costal margin of the 

 primaries, but it is less strongly defined than in males of 

 allied species, being little more than an irregularity of 

 the surface near the edge of the wing. Of this species 

 Mr. Blackburn says : — 



" I have taken at different times three specimens of 

 this species, all flying about some precipitous cliffs, 

 1500 feet or so above the sea, not far from Honolulu. 

 They were taken by day ; they appear to be of the 

 same sex."

FuHginous-brown ; wings with a blackish line along 

 the outer margin; fringes white, traversed by a blackish

 arched line, all dark brown with white borders ; a 

 blackish dot at the end of the cell; secondaries with 

 basal half white, gradually shading into the brown 

 colour of the outer half ; abdomen with white posterior 

 margins to the segments; wings below with fringe as 

 above ; primaries greyish, with sHght bronze reflections, 

 the commencement of the third transverse line of the 

 upper surface visible at costa ; basal area and internal

 near Honolulu, over which it flies freely in the sun-
