band above near tip. Wings hyaline; apical half of stigma dark, and also a 

 little at base, and pale just before the dark; a small dark spot at end of anal 

 vein. Veins dark, the forking of radial sector and lower side of discal cell pale. 

 Stigma of moderate size and height, ahnost right-angled behind; radial sector 

 and the median vein meet at one point; fork of radial sector twice as long as 

 the pedicel; areola postica about as high as long, rather narrow above; discal 

 cell one and a fourth longer than broad, slightly narrowed below, sides nearly 

 straight; posterior cells subequal. 

 Length to tip of wings 3.2 mm. 



PSOCUS PULCHELLUS, Sp. IIOV. 



Type.— M. C. Z. 10,796. Straits Settlements: Singapore (C. F. 

 Baker). 



Head pale, with a few faint marks, antennae pale, darker toward tip and 

 there the bases of the joints pale; thoracic lobes black, the middle one with 

 two spots; legs pale, tips of tarsi dark. Fore wings white, heavily maculate 

 with dark brown or black (Plate 2, fig. 17). The posterior cells almost wholly 

 dark, a broad oblique band from before end of anal vein up toward stigma, 

 but extending only a little above the median vein; base of stigma, and a mark 

 below, apex of stigma, two large, and several small spots in radial fork, and 

 several spots in area above median vein, and two spots in discal cell, one "cov- 

 ering the lower part, are dark brown; veins white, heavily dotted with dark. 

 Hind wings hyaline, veins white. Discal cell much longer than broad, scarcely 

 narrowed below, outer side concave; fork of radial sector four times as long 

 as pedicel; stigma low, and rounded behind; areola postica broad and low, 

 pointed above. 



Length to tip of wings, female 6 mm., male 5 mm. 



Psocus hermosus, sp. nov. 



Type.— M. C. Z. 10,784. Straits Settlements: Island of Penang, 

 Singapore (C. F, Baker). 



Head pale, a few spots on the nose, antennae pale, beyond third joint darker 

 at tips of joints; legs pale, base and tips of tarsi dark, lobes of thorax with 

 dark spots. Wings hyaline, densely marked with small irregular brown 

 patches, in the posterior cells occupying most of surface, along anal area the 

 spots are in transverse rows, also in rows across the stigma and crossing veins 

 behind and beyond it, several clouds in the discal cell and near by, tips of veins 

 marked with darker spots, also one at base of stigma, and a long curved black 

 mark behind the forking of radial sector. Veins pale, interrupted with dark;
