NEUROPTERA 45 



^ appendices of the usual form, the spines hardly reaching to their apex. Apical 

 ventral segment narrow, tongue-like. (Plate IV. fig. 10.) 



Expanse 13 — 16 mm. 



Hab. Molokai, Maui, and Hawaii (from 3000 — 5000 ft.). 



(18) Nesomicronms sienopteryx, sp. nov. 



Small, blackish, antennae and the posterior legs testaceous, anterior and middle 

 tibiae and femora for the most part dark, their tarsi testaceous. 



Wings very narrow ; anterior pair rounded at the apex, greyish-fuscous, slightly 

 fulvescent, with a black streak from the base, uniting with the dark inner series of 

 gradate nervules, to form a curved dark line. Radius with 5 sectors, nervuration dark, 

 interrupted by pale spaces. Posterior wings subhyaline, very lightly infumate, nervu- 

 ration somewhat dark for the most part, the nervures not conspicuously blackened 

 towards their apices ; apical margin very faintly, but just perceptibly excised. 



^ with the spines of the appendices, somewhat strong, extending to their apices, 

 crossing each other towards the apex. 



Expanse 1 1 mm. 



Hab. Haleakala, Maui (5000 ft.) ; i $. 



(19) Nesomicromus minimtis, sp. nov. 



Usually of a dark brown or black colour, sometimes paler, prothorax generally with 

 brown or yellowish markings in the darker specimens. 



Anterior wings rounded at the apex, narrow, greyish, or yellowish-grey, near the 

 base with two small black spots, one above the other and close together, situated one 

 on the cubitus anticus the other on the cubitus posticus. Other black or fuscous spots 

 are often present, but these are the most conspicuous, and apparently are never absent. 

 Radius normally with 4, rarely with 3 sectors. 



Posterior wings hyaline, nervuration pale and inconspicuous, but towards the apical 

 margin the nervures become black, and form a delicate marking. Pterostigma often 

 quite pallid and inconspicuous, but passing from yellow in some to testaceous in others, 

 and then very conspicuous. 



$ with the appendices of the usual form, their spines very finely serrulate, curved 

 upwards, extending slightly beyond their apices. (Plate IV. fig. 11.) 



Expanse 10 — 14 mm. 



Hab. Mountains of Molokai and Hawaii (3000 — 4000 ft.).
