NEUROPTERA 49 



(4) Anomalochrysa debilis, sp. nov. 



Form and colour as in A. sylvicola (the yellow longitudinal stripe not alv/ays 

 visible in dried examples), but considerably smaller. Nervuration pale ; gradate nervules 

 in the anterior wings black or dark forming four rows of cellules, the two middle ones 

 not generally completely separated ; posterior wings with three rows. All the cellules 

 in the gradate series distinctly but lightly infuscate on each side of the gradate nervules. 

 Abdomen clothed with pale hairs, apical dorsal plate of ^ not strongly dilated, erect, the 

 spine on each side at the base beneath, exceedingly fine and hair-like, both dorsal and 

 ventral plates clothed with pale hairs. 



Length 8 mm. Expanse 24 — 27 mm. 



Hab. Kona, Hawaii (about 3000 ft.). 



(5) Anomalochrysa peles, sp. nov. 



Form, colour and general appearance much as in the two preceding species. From 

 A. sylvicola it may be at once distinguished by the infuscation of the front wings, which 

 is more conspicuous than in A. debilis, nearly all the cellules of the anterior wings being 

 narrowly but distinctly clouded along the nervules ; and from either of those species it 

 may be known by the form of the third cubital cellule, the apical portion of which has 

 its apical and inferior angle strongly produced outwardly. Of the cellules formed by 

 the gradate nervules the upper and lower rows are distinct and very similar in size ; 

 between these there are at least three other rows more or less confused. In the 

 posterior wings four rows are more or less evident. Abdomen of ^ much as in the 

 preceding species. In the only example I have seen, the basal joint of the antennae, 

 the head, and front of the prothorax, are darker in colour, with a reddish tinge, but this 

 is hardly likely to be a constant character. The hairs on the nervures of the wings are 

 rather long and conspicuous. Ventral valve of apical abdominal segment with long 

 pale hairs. 



Expanse 32 mm. 



Hab. Kilauea, Hawaii ; a single Z taken. 



(6) Anomalochrysa montana Blackb. 



Anomalochrysa montana Blackburn, Ann. Nat. Hist. (5) xiv. (1884), p. 419. 

 Hab. Mauna Loa, Hawaii, at an elevation of nearly 7000 ft. (Blackburn). 

 Kilauea, Hawaii (4000 ft.).
