2 AMERICAN NEUROPTERA. 



each side toward base of wings, and a median paie spot on metascutellum ; abdo- 

 men brown. Wings hyaline, venation pale brown, dark spots at base and tip of 

 pterostigrna, and at ends of veins, those on apical part almost touch each other 

 to form a band. Legs pale. Venation as usual in the genus, the pterostigrna 

 rather broader toward tip than in E. canadensis. The tip of male abdomen has 

 two long, slender, erect, curved pieces, and a stouter, acute, median piece be- 

 tween them. Length 3 mm. 



One specimen from San Mateo Co., Cal. (Baker). 



PSOCUS californiciis n sp. — Head grey, nasus blackish, with about 10 

 white lines, ocelli on black spot, and a black spot in niiddle of vertex, and a 

 brown one over each eye; antennae dark, basal joints pale; niesothorax black, 

 with a yellow Y, and a pale band between it and the black nietathorax ; abdo- 

 men black above, pale below, legs pale, femora darker. Wings hyaline, venation 

 brown, the base of fork under pterostigma white, and also the veinlet closing the 

 cell, the posterior half of outer side of cell and the cubitus from the cell to next 

 fork white ; pterostigma white at base, rest dark brown or black, an oblique dark 

 band across wing near base of cell, not very strongly marked, ending in a black 

 dot at end of anal vein ; two spots basad of this band. Length 3.2 mm. 



One specimen from the mountains near Claremont, Cal. (Baker). 



Psocus floridanui^ n. sp.^Head pale, nasus lineate with black, ocelli on 

 a dark spot; some small brown spots on middle and sides of vertex, antennae 

 brown. Thorax black, with a pale median stripe; legs pale, femora darker; ab- 

 domen brown, with pale spots toward tip. Wings hyaline, rather whitish on 

 basal part; venation black, posterior part of veinlet closing discal cell white, as 

 also the fork of radial sector, a spot basad of discal cell, and an elongate spot at 

 anal angle black, the anal margin also black for some distance out; pterostigma 

 with basal black dot, and a large spot in apical half extending behind the cell. 

 Vertex slightly convex ; antennae rather short. Discal cell touching radial sec- 

 tor, fully one and one-half longer than broad at base, the tip about one-thiid 

 shorter than base, the outer side slightly concave ; the pterostigma angulate be- 

 hind. Length 3.6 mm. 



Two Specimens from Biscayne Bay, Florida (Slosson). 



Psocus confrateriius n. sp. — Head pale, ocelli on a black spot; nasus 

 pale, with about ten black lines, a dark patch on middle of vertex; antetina' 

 brown; thorax dull black, a yellow Y on mesotborax ; legs dull yellowish, 

 femora rather dusky above; abdomen blackish. Wings hyaline, venation mostly 

 black, the posterior side of discal cell and the posterior part of outer side are 

 white, also the base of fork of radial sector is white ; .the pterostigma has a black 

 spot at base and a large blackish spot occupying most of its area; there are two 

 incomplete and sometime more or less indistinct blackish bands on basal half of 

 the wing, and a black point at end of anal vein. Hind wings hyaline, with 

 blackish venation. Antennae rather long, hairj-, vertex straight across on top; 

 wings moderately long; discal cell about twice as long as broad, scarcely one- 

 third broader at base than at tip, outer side rather convex beyond middle, inner 

 side slightly convex, the veinlet connecting radial sector to the discal cell is
