NEUROPTERA 43 



The antennae agree with those of the preceding species in having the two basal 

 joints testaceous, but the rest are much darker, pale narrowly at the base. 

 Expanse 16 mm. 

 Hab. Haleakala, Maui (4000 ft.) ; i $ taken in April, 1894. 



(13) Nesomicromus brunnescens, sp. nov. 



Brown or blackish brown, legs and antennae testaceous, the joints of the latter 

 infuscate on their apical portion. 



Anterior wings brown, or brownish grey (the latter colour probably only in 

 examples not fully mature), rounded at their apices, radius giving off 7 — 9 sectors, the 

 gradate nervules forming two obliquely transverse, fine dark lines, sometimes very in- 

 distinct, the cellules between the two series very narrow in proportion to their length. 



Posterior wings subhyaline, somewhat iridescent, nervuration light brown or 

 yellowish, the outer series of gradate nervules darker. 



$ appendices narrow towards the apex, not strongly produced, their spines some- 

 what strong, curved upwards, serrulate, and extending back to the apices of the appen- 

 dices or even slightly beyond them. (Plate IV. fig. 9.) 



Expanse 14 — 16 mm. 



Hab. Molokai, Lanai, and Haleakala, Maui. Rare (2000 — 5000 ft.). 



( 1 4) Nesomicromus rubrinervis, sp. nov. 



Head, thorax, legs and antennae testaceous, abdomen darker. 



Anterior wings narrow, their apices rounded, pale brown, tinged with pink, the 

 nervuration pink. Radius with four sectors. Nervules of inner gradate series sub- 

 infuscate, forming a faint dark line. In this series four of the transverse nervules are 

 nearly continuous and form a slightly oblique line, but the two upper ones of the series 

 are greatly separated from the four lower, and from one another. Posterior wings 

 nearly hyaline, the nervuration and pterostigma pink. 



Spines of the appendices of ^ reaching about to their apex, and curved upwards. 



Expanse 13 — 14"5 mm. 



Var. a. Dark brown in colour, wings dark, shorter and wider than in the type, 

 pterostigmata and nervuration pink. Radius with 5 sectors. 



The dark colour may really be normal, the two examples described above being 

 possibly immature. The pinkish tinge to the wings and the condition of the inner series 

 of gradate nervules is so similar, that I have little doubt that the two forms are one 

 species, in spite of the additional sector to the radius. 



Expanse 14 mm. 



Hab. Kilauea, Hawaii (4000 ft.) ; i ^ 2 $.
