NEUROPTERA 79 



(4) Psocus hualalai, sp. nov. 



Allied to P. haleakalae, but readily distinguished by the less conspicuous wing- 

 markings. The apical portion at least of the pterostigma is black, and there is a spot 

 below adjoining it, and one on the transverse portion of the inner branch of the 

 cubitus, as in that species. The median fascia is usually represented by two or three 

 disconnected spots, which, however, are sometimes sufficiently developed to form a 

 transverse band, but this is always more or less interrupted. The head above the 

 antennae is for the most part dark. The antennae of the Z have a pubescence similar 

 to that of P. haleakalae, and the eyes are widely separated, the width of one of these 

 being only about equal to the distance between its inner margin and the nearest ocellus. 

 In the % the eyes are still smaller. 



Expanse circa 9 mm. 



Hab. Mauna, Hualalai (about 8000 ft.). 



(5) PsocHS konae, sp. nov. 



Allied to P. simttlator, but distinguished by the lack of the distinct median fascia 

 of the anterior wings, which is represented by two or three detached spots. The small 

 spot on the cubitus between the base of the wing and the median fascia is also wanting. 

 In the wing-markings this species exactly resembles some examples of P. hualalai, but 

 from that species the large eyes of the t, which are similar in size to those of P. 

 simulator, will easily separate it. 



I have not seen the % of this species. 



Expanse 10 mm. 



Hab. Kona, Hawaii (4000 ft). 



(6) Psocus kauaiensis, sp. nov. 



Of smaller average size than any of the preceding species, and varying greatly in 

 the wing-markings. Sometimes the anterior pair have an entire submedian transverse 

 dark fascia, as in P. haleakalae, &c., sometimes this is broken up into two or three 

 separate spots, as in P. hualalai, &c., or the wings may be without any markings, 

 except the dark pterostigma. The most usual form is that which resembles typical P. 

 hualalai in markings. The transverse portion of the inner branch of the cubitus is 

 dark on the part towards the costal margin, pale towards the other extremity, but it is 

 not traversed by a distinct black spot as in all the preceding species, and at the most 

 shows a hardly perceptible infuscation along its margins.
