NEUROPTERA 83 



furcation of the inner branch of the cubitus. The mesothorax in both sexes is more or 

 less smooth and shining. The third joint of the antennae in the t is conspicuously 

 clothed with long hairs, which stand out strongly from the surface of the joint. The 

 eyes are of about the size of those of the preceding. 



Expanse 9 — 10 mm. 



Hab. Mountains of Kauai (4000 ft.). 



STENOP.SOCU.S Hag. 

 ( I ) Stenopsocus pulchripennis, sp. nov. 



Head black, the face shining, behind the post-clypeus with indefinite brown 

 markings. Antennae black, with very long and slender joints, the third with the 

 apex dark, the rest pale, the pubescence is short in general, but at intervals there 

 are placed rather long single hairs. 



Anterior wings hyaline, with three transverse dark fasciae, the basal one broad, 

 extending from near the radius to the dorsal margin, the middle one very narrow 

 along the inner branch of the cubitus. The ajaical fascia extends transversely from the 

 costa, at the apex of the pterostigma, to the inner branch of the cubitus, when it 

 becomes deflected along that nervure and its terminal furcations, forming an irregular 

 dark apical mark, containing two clear spaces. All the nervuration pale as far as the 

 basal fascia from the base of the wing, beyond this, dark. Discoidal area quadrangular. 

 Pterostigma at the apex obliquely truncate, its inner angle connected by a pale nervule 

 to the point of furcation of the inner branch of the radius. Area postica very small, 

 triangular, appendiculated at its vertex, the area adjoining it on the apical side very 

 large, longer than high, as large or larger than the other two areas formed by the 

 apical furcations of the inner branch of the cubitus, taken together. Posterior wings 

 clear, nervuration dark. 



Length of anterior wing 2 '5 mm. 



Hab. IVIount Hualalai, Hawaii (8000 ft.). This is certainly no true Stenopsocus, 

 but as 1 have seen only one much mutilated example, I have only been able to examine 

 it very imperfectly. The wings show no trace of a marginal fringe, nor of hairs on the 

 nervuration, but it is possible that this may be due to abrasion. 



Elipsocus Hag. 



(i) Elipsocus montanus, sp. nov. 



Body black or dark brown, the front of the head, the margins of the thorax, 

 and generally some lines on the abdomen more or less pale.
