308 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 



areola postica high, narrow above, discal cell longer than broad, inner side 

 slightly convex; veins black, fork of radial sector pale at one point. Antennae 

 long, third joint slightly curved, subclavate, with long black hair, but not as 

 dense as in D. atratus, fourth joint slender, with moderately long hair. 

 Length to tip of wing 7.5 mm. 



PODOPTEROCUS, gen. nov. 



Venation as in Psocus; median and radial sector connected by a cross-vein, 

 stigma long and slender; wings long and slender, without hairs. Antennae 

 very long, the third joint somewhat thickened, especially in middle, densely 

 hairy, fourth and fifth joints very long and tenuous, beyond the antenna is 

 broken up into a great number of short fusiform joints. The hind tibia bears 

 a wing-like expansion on each side (Plate 1, fig. 4).

PODOPTEROCUS LONGICORNIS, sp. nov. 



TYPE. M. C. ,Z. 10,785. Straits Settlements: Singapore (C. F.

Brown, few, if any, markings; antennae brown, third joint with black hair; 

 legs brown, femora darker at tips. Wings faintly brown, base black for short 

 distance out, stigma black, as also an area behind it, the margin beyond stigma 

 also blackish. Veins mostly brown; discal cell nearly twice as long as broad, 

 scarcely narrowed below, outer side rather concave; stigma very low and 

 slender; fork of radial sector fully twice as long as the pedicel; areola postica 

 as high as long, moderately broad above. Expansion of hind tibia on lower 

 side broadest near base, on upper side broadest beyond the middle. ' 



Length to tip of wings 6.5 mm. 



GRAPHOPSOCUS SUBAEQUALIS, sp. nov. 



TYPE. M. C. Z. 10,790. Straits Settlements: Singapore (C. F. 

 Baker). 



Pale; a dark mark over ocelli, reaching each side to eye; lobes of thorax 

 with shining black spots; legs pale; wings hyaline, veins dark, nearly black; 

 stigma unmarked. Wings and venation about as in G. infirmus; it differs in 

 having the fork of the radial sector about equal in length to the pedicel, and the 

 areola postica is large, longer than high, and very short pedicellate; stigma 

 shaped as in other species, and the connecting veinlet behind stigma ends 

 about opposite the second branch of the median vein. 



Length to tip of wings 4 mm.
