1. N. fUlcicola Kirk. 



This differs from the species of Aloha by the very short teg- 

 mina of a coriaceous texture and with reticulated surface. Anal 

 spines short, thick, straight, bases contiguous, diverging; styles on 

 the plan of A. ipomoeae : aedeagus flattened laterally, a cock's comb 

 of three spines on dorso-apical area and a single one on ventral area 

 near apex, a large one on left side near apex. I should consider 

 this as a development of the ipomoeae group.

NesopJcias ninihafa Kirkaldy, 1910, 1. c. 



This has the same short tegm'ina as filicicola but not so coria- 

 ceous or with such distinctly reticulated surface. Anal spines very 

 long and thin, slightly diverging towards apices; styles somewhat 

 like those of A. kirkaldy i but shallowly emarginate on outer edge; 

 aedeagus laterally flattened, three small spines on dorso-apical area, 

 a large blunt one on dorso-apical area, four or five on ventro-apical 

 area and a large one on ventro-basal area, a large spine on right 

 side toward apex.* 



Whilst these two species are congeneric, the question arises 

 whether they are homophyletic, or if one has branched from 

 the ipomoeae group and the other from the kirl-aldyl group.

Bv the single frontal carina this species should come near 

 one of the Nesosydiie group, luit the aedeagus has greater 

 affinity to Nesoi-estias ftVicicola. so that there is the possibility 

 of the single carina being of independent origin. 



Anal segment sunk well into pygophor, anal spines very minute; 

 pygophor very shallow; styles broad at base, curved, with long spine 

 at apex nearly at right angle to broad basal portion; aedeagus flat- 

 tened laterally, deep for basal two-thirds, a "cock's comb" of five 

 spines on dorso-apical area and some five or six small spines on left 

 side near apex. 



*In specimens taken by Mr. Timberlake off Phegopteris the spine 

 on right side of aedeagus is not so large and the ventral spine thinner.
