78 FAUNA HAWAIIENSIS 



greater than, the width of the two together. In the % they are somewhat more remote. 

 The antennae of the ^ near the base are clothed with long and conspicuous hairs, which 

 stand out on all sides nearly erect from the surface, but towards the apex they become 

 less so. In the $ the antennal hairs are much shorter, and inconspicuous. 



The surface of the mesothorax is dull, and its margins more or less pale. 



Wings hyaline, the anterior slightly infuscate along the margin about the apex. 

 At the extreme base there is a dark band, and a very distinct unbroken transverse fascia 

 about the middle. The apical portion of the pterostigma, a spot beneath and adjoining 

 this, and one on the transverse portion of the inner branch of the cubitus, are also black 

 or dark. Posterior wings with an infuscation on the dorsal margin towards the base. 



Legs pale, the tarsi dark. 



Abdomen more or less pale, at least in some examples. The apical ventral 

 segment of the ^ is flat at the base, but the apical portion is bent upwards at right 

 angles to this and forms a sort of long process. 



Expanse 8"5 — lo mm. 



Hab. Haleakala, Maui (5000 ft.). 



(2) Psociis simulator, sp. nov. 



Resembles the preceding in general appearance. It is rather larger, the median 

 transverse fascia of the anterior wings is slightly interrupted about the middle. There 

 is a small spot on the cubitus about half-way between the base of the wing and the 

 median fascia. In the ^ the eyes are much larger, the width of one of them (in a front 

 view of the head) being considerably greater than the distance between its inner 

 margin and the nearest ocellus. 



Expanse 10 — W2 mm. 



Hab. Haleakala, Maui (5000 ft.). The ^ is quite distinct by the size of the eyes 

 should the slight colour distinctions prove inconstant. 



(3) Psocus imictcs, sp. nov. 



One of the largest Hawaiian species, wings hyaline, faintly clouded. The ptero- 

 stigma is for the most part brownish and there is no spot adjoining it. There is a faint 

 fuscous stain, forming a transverse band, which passes through the cubitus at its 

 furcation. Otherwise the wings are without markings. The median lobe of the 

 mesothorax is faintly shining in front. The unique example appears to be a $, but the 

 eyes are more prominent than is usual in that sex, although they are widely separated. 

 The pubescence of the antennae is short and inconspicuous. 



Expanse i3'5 mm. 



Hab. Haleakala, Maui (5000 ft.) ; unique.
