suffused oblique ochreous transverse spot almost at base; a tuft of raised 
scales at base; a cloudy blackish transverse line from } of costa to 4 of 
inner margin, tolerably rectangularly angulated in middle, preceded by two 
large tufts of raised scales above and below middle; beyond this the ground- 
colour is suffusedly paler or mixed with ochreous-whitish towards costa ; 
costa suffusedly dark fuscous towards middle; two tufts of raised scales in 
disc beyond middle; a very ill-defined dark fuscous transverse line from 
4 of costa to anal angle, angulated inwards beneath costa, sometimes 
followed on costa by an ochreous-whitish spot: cilia fuscous, with two 
cloudy blackish lines. Hindwings dark fuscous-grey; cilia fuscous, with a 
cloudy darker line. 
Differs from all by the general dark fuscous colouring, without definite 
pale markings; it is shorter-winged than any preceding species except 
T. leucoplanetis.
