NEUROPTERA 47 



natural position of the wings marks off a dorsal from a lateral field. The nervuration 

 is not to be definitely made out, but the transverse nervules are excessively numerous 

 and divide the wing up into great numbers of small square or subcircular cellules ; the 

 nervures bear no hairs, nor is there any trace of a marginal fringe. Posterior wings, 

 none. 



The (T characters are similar to those of Nesoniicroimis and Pseudopsectra. 



(i) Nesothauma haleakalae, sp. nov. 



Black, head with pale markings and sometimes the thorax. Antennae variable in 

 colour, the basal joint sometimes black, sometimes testaceous. 



Wings black with yellow markings, or yellow with black and fuscous markings, 

 very variable in colour. (Plate IV. figs. 13, 13a & i3<5.) 



Appendices of Z narrow towards the apex, and pale in colour, their spines slender, 

 long, crossing each other, and extending considerably behind the extremity of the 

 appendices. 



Length about 4 mm. Expanse 6 — 7 mm. 



Hab. Haleakala, Maui (5000 ft.). Rare. 



CHRYSOPIDES. 

 Anomalochrysa M'Lachl. 



(i) Anomalochrysa princeps, sp. nov. 



Head, thorax, abdomen, legs and antennae flavous. A large species of slender 

 form, but variable in size. 



Prothorax with pale and rather long pubescence, gradually attenuate from the base 

 forwards, and with a transverse impressed line near the base. 



Wings with pale nervuration, the anterior much broader than the posterior, the latter 

 subfalcate. The former are ornamented with sparse black, or blackish, spots. Their 

 nervuration is not conspicuous, many of the nervules being in part, or wholly, almost 

 colourless, and for the rest of a pale yellow colour, the whole set with pale hairs. The 

 gradate nervules form four longitudinal rows of cellules, the two middle ones sometimes 

 more or less confused, and one or other of them incomplete. Dividing nervule of third 

 cubital cellule received in the apical side of the cellule, instead of in the upper (i.e. the 

 cubital nervure), as is usual in the genus. Posterior wings subfalcate, three distinct 

 rows of cellules formed by the gradate nervules, a fourth sometimes more or less 

 indicated. All the pterostigmata pallid, the wings subhyaline, tinged with yellow.
