inward to the sharp apices. As a result the distal extremity is itself sharp 
and directed mesad, not bearing on its internal face the minute tooth df 
rected mesad that is characteristic of most of the species of the genus. 
The series from Kilauea is recessive in coloration; straw color, with 
limb markings very weak and in two of the males the triangular area of 
the tegmina, normally suffused with darker brown, shows but a faint trace 
of such suffusion.

This species is evidently close to P. varians Perkins, differing 
in the average shorter and more truncate male tegmina. The gen- 
eral coloration is pale, with limb markings subobsolete or weakly 
defined. In the male, however, the darkened triangular area of the 
tegmina is conspicuous. 
The contrast between debile and varians is somewhat analo- 
gous to that which exists between the North American species, 
Nemobius fasciatus (DeGeer) and Nemobius maculatus Blatchley, 
though in the present case genitalic differences are not apparent.
