In general Bimilar to Sigmatoneura, l>ut the third joint of the antennae if

This genua is much like our American Cerastipsocus, but differs in 

 the antennae; it is also near Syngonosoma, which has the fourth joinl 



of antennae also thickened.

Type.— M. C. Z. 10,800. Borneo: Sandakan. Philippines — Mt. 

 Banahao (C. F. Baker). 



Blackish; a pale stripe through pleura and on sides of the abdomen, femora 

 pale at base; wings blackish, stigma and space behind it deeper black; vena- 

 tion dark, lower branch of fork of radial sector, lower end of discal cell, median 

 vein from discal cell out to near tip, and the bases of the branches of median 

 vein, are pale yellowish, in one specimen the upper and outer sides of discal 

 cell are also rather pale. Antennae long, third joint subclavate, densely 

 haired, fourth joint and beyond very slender, with few short hairs. Wings
