NEUROPTERA 87 



is much more uniform over the whole surface. The pterostigma is uniformly infuscate 

 like the wings, but not otherwise darkened. 



Expanse 5 '5 — 6 mm. 



Hab. Haleakala, Maui (5000 ft.). 



(9) Elipsocus ii/icrajjiaunis, sp. nov. 



Face yellowish, the post-clypeus with dark lines, generally with a radiate arrange- 

 ment, front dark about the ocelli, and a number of very conspicuous dark spots, placed 

 closely together near the inner margins of the eyes, on each side. Thora.x and 

 abdomen dark. The anterior wings are strongly infuscate, the infuscation extending 

 from near the base to the apex, and occupying a large part of the middle of the wing 

 and about the apical branches of the inner division of the cubitus. The general appear- 

 ance of the wings is dark with paler areas. The latter are chiefly the region around 

 the pterostigma, some small spots on the apical margin, part of the area postica and the 

 region adjoining this on the basal side, and sometimes more or less of the wing at the 

 base. The nervure forming the apical side of the area postica is colourless to the 

 vertex, which touches and is confluent for some distance with the inner branch of the 

 cubitus. The pterostigma is abruptly truncate at the apex, its apical margin, and more 

 or less of the inner margin towards the apex conspicuously blackened, as also the spot 

 at its base. The inner branches of radius and cubitus at the point where they are 

 angulated do not meet, but the angles are rather distant, and connected by a transverse 

 nervule of a white colour. 



Expanse 4"5 mm. 



Hab. Kona, Hawaii (4000 ft.). This minute species is easily distinguished by 

 the form of the area postica, and the nervuration is not that of the genus Elipsocus at 

 all. Nevertheless I have not cared to separate it, because of the fact that other species 

 have a tendency towards a similar nervuration, e.g. E. inconstans (supra, q.v.). 



(10) Elipsocus frigidus, sp. nov. 



Size and general appearance of the preceding, from which it differs in the less 

 strongly blackened apical margin of the pterostigma, and the fact that the nervure 

 defining the vertex of the area postica, though contiguous to, does not become confluent 

 with the inner branch of the cubitus at that point. I have seen but two examples 

 which are in poor condition, and it is not improbable that a good series of examples 

 would show this to be a variation of the preceding species. (Cf variation of E. 

 inconstans)^ 



Hab. Hualalai, Hawaii (8000 ft.).
