608 PROCEEDINGS OF THE ACADEMY OF [NoV., NEW NEUROPTEROID INSECTS, NATIVE AND EXOTIC. BY NATHAN BANKS. The descriptions of the following new species have accumulated during the past year, based mostly on accessions to my collection, but the types of some (indicated in text) are in other collections.

Legs pale brownish. Wings faintly fumose, venation brownish. Ocelli as in P. signata; pronotum a little broader than long. Wings about as in P. signata, the apical cross-veins confined to subcosta, radius or its branches, the costal margin concave at humeral cross-vein. Female ventral plate with a median excision, and a curved tooth each side. Expanse 28 mm. From Mt. Washington (Mrs. Slosson). Perlodes tibialis n. sp. PI. XXVIII, fig. 19.
