Calopsocus rizali sp. nov. Plate I, figs. 1 and 2. 



Yellowish; antennae blackish, except basal joints pale, tips 

 of palpi black; thorax unspotted; legs pale, tibiae infuscated or 

 nearly black. Wings uniform pale brown; venation irregular, 

 usually the radius is not as evenly three-branched as in the figure. 

 Venation of hind wings much like that of O. infelix, but the upper 

 fork much shorter than the lower one. Antennse with long hairs 

 on basal parts; head broad, the vertex with a deep median in- 

 dentation, the lobes higher than the eyes. Wings longer than 

 in C. infelix; the area beyond the stigma bent downward. 



Length to tip of wings, 4.3 millimeters. 



Luzon, Tayabas, Malinao {Baker).

Psocus taprobanes var. luzonensis var. nov. 



Agrees very closely with Enderlein's figure of variety benga- 

 lensis, but the fork of the radius contains only three dark dots, 

 the basal band extends up to the radius, a pale spot at base of 

 second posterior cell only, the white marginal spots cover the 

 marginal vein, and between them the margin is much darker 

 than elsewhere. The stigma is broader than he figures, but 

 not quite angulate behind; the radial fork is much longer than 

 he figures, being fully as far basal as the first fork of the median 

 vein, and its pedicel is not as long as the outer side of discal cell. 

 Head pale; nasus faintly lineate; thorax pale; all tarsi black 

 on last joint and dark at tip of tibia. 



Length to tip of wings, 6 millimeters. 



Luzon, Laguna, Mount Maquiling (Baker). 



True P. taprobanes is found in Java, Ceylon, and doubtless 

 in other islands. 



Amphigerontia sp. 



A black-winged specimen of this genus from Mount Banahao 

 is in too poor condition for description.
