46 FAUNA HAWAIIENSIS 



PsEUDOPSECTRA, gen. nov. 



Allied to Nesomicroinus. Antennae longer than the anterior wings. Maxillary 

 palpi with the terminal joint long, acuminate, twice as long as the preceding. Prothorax 

 short. 



Anterior wings very short, rounded at the apex, strongly convex above, and 

 concave beneath, coriaceous and opaque, costal and apical margins fringed, the dorsal 

 one bare. Nervuration without hairs. Costal area with no recurrent nervule at the 

 base, and not strongly dilated. Six or seven sectors to the radius. 



Posterior wings very minute in both sexes, forming small subtriangular lobes. 



Z characters as in Nesomicronms, the appendices each furnished towards the base 

 on their inferior margin with an upturned spine, which is finely serrulate. 



(i) Psendopsect7'a lobipennis, sp. nov. 



Brown or nearly black, the legs and antennae testaceous, the latter with darker 

 annulations, the former with the front and intermediate tibiae with more or less distinct 

 fuscous markings. 



Anterior wings brown or yellowish-brown, gradate nervules infuscate forming dark 

 lines, nervuration with alternate darker and paler spaces, and there are distinct dark 

 spots placed all round the margins of the wings. Posterior wings subtriangular narrowly 

 rounded at the apex, with one very thick longitudinal nervure, and one or two others 

 much less distinct. 



Appendices of t short, clothed with long hairs, their spines strongly developed, 

 crossing one another, and extending to the apices of the appendices. (Plate IV. 



fig- 12.) 



Expanse 9 mm. 



Hab. Haleakala, Maui (5000 ft.). One ^ and one ? taken. 



Nesothauma, gen. nov. 



Antennae short, apical joint of maxillary palpi long, about twice as long as the 

 preceding. Head and thorax strongly, densely and roughly punctured. 



Prothorax bilobate in front. Anterior wings very small, their texture almost that 

 of the elytra of a Coleopterous insect, the dorsal margin very strongly rounded, the 

 costal margin much less strongly. Their surface is strongly convex, but somewhat 

 depressed along the margins, which are reflexed. At the base, for about one-third its 

 length, the wing is strongly compressed into a strong longitudinal carina, which in the
