each side, and several grouped into a figure at center about ocelli ; mesothorax jiale, 

 with a median brown spot behind; similar spots on front and hind margins of meta- 

 thorax. I-egs pale ; femur I banded with brown at middle and before tip, other 

 femora banded near tip only ; tibice with bands near base and near tip, sometimes 

 indistinct ; tarsi dark. Abdomen pale, marked with brown in uncertain manner 

 from dried specimens. Wings hyaline, heavily marked with dark brown as follows : 

 an incomplete bgisal band, a median band starting from near middle of costal margin 

 and extending obliquely backward, in its posterior part with a hyaline spot ; the 

 apical half of the pterostigma brown, and a band reaching from it across the wing ; 

 the apical part of wing clouded with brown, but leaving clear spaces between the ter- 

 minations of the veins ; just basad of this band is a crescent of six black spots, one in 

 each cell, the posterior ones forming eye-spots. There is also a patch of small black 

 spots near middle of wing, and a couple near middle of posterior margin. The vena- 

 tion is mostly whitish or pale, except where the wing is dark, where the veins are 

 also dark. Hind wings hyaline. Venation of true Psoais, the discal cell about twice 

 as long as wide, and nearly equally wide throughout. Pterostigma rounded behind. 

 Length to tip of wings 4.4 mm. 



Specimens come from Franconia, N. H. ; Ithaca, N. Y., Septem- 

 ber I ; and Falls Church, Va., July 12. Separated from all our other 

 species by the ocellate markings in apical part of fore wings. It is 

 apparently allied to the European F. sexpunctafiis, but the wings are 

 more slender, more heavily marked, etc. 



Psocus tolteca, sp. no\ . 



Head entirely yellow ; antenna; black ; palpi black ; lliorax and abdomen black, 

 the latter indistinctly banded with pale on base ; legs dark or black, the femora some- 

 times paler than the other joints. Wings hyaline, with a large basal black mark, a 

 black V-mark, and an apical black band reaching base of the V-mark. This marking 

 is thus like that of P. iiigrofasciatus I'rov., but the apical mark extends to the margin 

 on the veins, leaving a clear space between veins. The wings are more slender than 

 in that species, and the head is wholly yellow. Length 6-7 mm. 



Many specimens from Guadalajara, Mexico. 



Peripsocus fumosus, sp. nov. 



I'ale yellowish-brown without distinct markings ; the ocellar spot shining black 

 and two faint marks behind ; the lobes of thorax darker in middle than on the sides. 

 Antenna dark, rather large, pilose. Legs pale brownish, the femora above, and the 

 tarsi darker brown ; abdomen dark brown. Wings uniformly dull blackish, with a 

 minute white spot at tip of posterior branch of median vein. Venation blackish ; hind 

 wings not so heavily fumose. The radial sector forked just above the last fork of 

 the median vein. Length to tip of wings, 3 mm. 



Two specimens from southwestern Colorado (Oslar). 



Peripsocus californicus, sp. nov. 



Head pale, nasus brown, vertex with two brown spots ; thorax and abdomen 

 marked with brown ; antennce pale, basal joints reddish ; legs pale. Wings hyaline.
