cealed. Thorax nearly glabrous beneath. Posterior femora in 

 male with apical tuft of long hairs above, tibia- somewhat dilated, 

 containing tuft of hairs in groove. Forewings with vein 1^ 

 furcate at base, lower fork faint, 5 from middle of transverse 

 vein, 6 from upper angle of cell, 7 and 8 out of 9, 9 from con- 

 siderably before angle of cell ; 10 out of 9, anastomosing with 11 

 and then with 9, 11 anastomosing with 12 before anastomosing 

 with 10. Hind wings with frenulum developed; Ic absent, 5 

 absent, 6 and 7 widely remote, 8 anastomosing shortly with upper 

 margin of cell near base, and closely appressed to 7 for a short 

 distance beyond cell. 



Probably a very early form of Geometrina, related to the an- 

 cestral form of the Boarmiadfu.
