86 FAUNA HAWAIIENSIS 



but vague, infuscation, and the clouding of the apical part of the wings is more 

 extensive, not being confined to the area between the inner branches of the cubitus 

 and radius, although that part is generally slightly more deeply clouded than the rest. 

 The apex of the pterostigma is more obtuse, and the inner branches of the radius 

 and cubitus are directly in contact at the point where they are angulated. 



Expanse 6 mm. 



Hab. Waianae Mountains, Oahu (above 2000 ft.). 



(6) Elipsocus erythrostictus, sp. nov. 



Allied to the preceding, the apical extremities of the nervures with a similar 

 appearance. Anterior wings with a yellowish tinge, the nervuration pale at the base, 

 dark towards the apex. This species is readily distinguished by the two crimson or 

 pink marks in the pterostigma, one of which is small, and situated at the basal 

 extremity, the other at the apical is paler and more diffuse. 



Expanse 5 '2 mm. 



Hab. Kona, Hawaii (2000 ft.). 



(7) Elipsoais vinostis M^Lachl. 



Elipsocus vinostis M^Lachlan, Ann. Nat. Hist. (5) xii. 1883, p. 228. 



The colour of the pterostigma which is given as the main character of this species 

 is probably not constant. The species appears to vary greatly in size and colour and 

 also in the shape of the pterostigma itself. Some examples have the wings entirely 

 infuscate. 



Hab. Many and probably all of the Islands, in the forests. 



(8) Elipsocus inaequi/uscus, sp. nov. 



Allied to E. vinostis, but easily distinguished by the more variegate appearance 

 of the anterior wings. These are rather deeply infuscate for the most part but clearer 

 in places. The greater part of the area postica, and more or less of the wing adjoining 

 it, are always pale and subhyaline, and the region between this area and the nearest 

 branch of the inner division of the cubitus is always very perceptibly more deeply 

 infuscate than the wing in general. The nervuration is dark and very similar to that 

 of E. vinostis, but in that species the infuscation of the wings, whether deep or light,
