NEUROPTERA 39 



(4) N esomicrotnus drepanoides, sp. nov. 



Dark brown or nearly black, legs and antennae pale. Anterior wings dark brown 

 more or less mottled with lighter yellowish-brown, or nearly entirely pale yellowish- 

 brown with the gradate nervules delineated by transverse dark lines, the radius with 

 the usual alternate dark spots, and some dark markings near the base of the wing. 

 Posterior wings more or less infuscate. Pterostigma sometimes pink. 



Allied to the preceding species, but with the apical margin of the anterior wings 

 more deeply excised, and the dorsal margin from the apex to about the middle, 

 evidently, but very slightly, concave. The wings are also less narrow. The sectors of 

 the radius are 6 or 7 in number, whereof the two which are nearest the base sometimes 

 unite close to their point of origin. The general appearance of the nervuration is that 

 of the preceding. In the $ the spines of the apical processes appear to extend about 

 to the apex of each process, and they cross each other near the base. (Plate IV. 

 fig. 6.) 



Expanse 14 — 16 -5 mm. 



Hab. Kauai (4000 ft), i ,?, 3 ? taken. Of the latter one example is much paler 

 than the others (as described above), and it also has broader wings, but I doubt whether 

 it is specifically distinct ; in fact no two individuals out of the four agree. 



(5) Nesomicronius paradoxus, sp. nov. 



Nearly black, the legs and antennae and some marks on the dorsum of the thorax 

 pale. Anterior wings dark brown, the costal area hyaline for the most part, and some 

 pale spots around the margins, especially along the apical. Posterior wings nearly 

 entirely infuscate. 



The apical margins in both pairs of wings are excised, in the inferior, very lightly. 

 The dorsal margins of the superior pair are also deeply excised to about the middle, 

 forming there a conspicuous rounded lobe, after which they are slightly concave to the 

 base. The nervuration is black and distinct, and hardly perceptibly furnished with 

 hairs. There are 6 sectors to the radius. (Plate IV. fig. 7.) 



Expanse 12 mm. 



Hab. Kilauea, Hawaii (4000 ft.) ; i %. 



(6) Nesomicromus fulvescens, sp. nov. 



Dark brown with pale markings, antennae and legs pale. Anterior wings pale 

 yellowish-brown, largely but not deeply infuscate from the region of the inner gradate 

 series to the apical margin. The outer gradate nervules are blackish and infuscate,
