I have coQipared the types of both species of Walker {supra) 

 with the description given by Stal, who had examined the type of 

 the Fabrician species of F. ferrugata, and agree with MeHchar in 

 considering theui as conspecific. Stal's description is here repro- 

 duced : — " Very palely sabtestaceous flavescent, here and there 

 covered with a whitish powdery substance ; wings whitish ; apical 

 margins of the last two segments of the abdomen, in $ at least, 

 black towards the sides ; very close to F. ocellata, Fabr., hardly 

 differing, except in coloration, unless in having the apical com- 

 missural angle of the tegmina a little less produced and somewhat 

 straight, not distinctly acute ; pronotum with a less distinct single 

 median ridge ; head truncate, vertex very obtusely angulated 

 anteriorly, concealed by the pronotum ; face a little longer than 

 its breadth beneath the middle, gradually slightly amplified from the 

 base to beyond the middle, thence on both sides obtusely rounded 

 and furnished with an obtuse median ridge running through it, 

 slightly impressed on both sides within the lateral margins, not 

 tumescent at the base : pronotum with a median ridge." (Stdl.) 



In some specimens the tegmina are virescent, in others suffused 

 with ochraceous or flavescent-testaceous, or wholly of that colour, 

 or in some virescent specimens the extreme margins of the tegmina 

 are dull ochraceous or testaceous.

Division NEPHESARIA. 



Tegmina never twice longer than broad, usually about one and 

 a half times as long, the apical margin truncate, but the posterior 

 angle not produced ; wings generally as broad, or nearly as broad, 

 as the tegmina. 



This division comprises a large number of genera found in all 

 the warmer regions of the world and our knowledge of it is at 

 present very limited. To it belong many of those small Flatince 

 which have a somewhat common facies, but which when the 

 venation of the tegmina and other characters are studied are found 

 to belong to the most divergent genera. They have been little 

 collected, but are as interesting, and deserve as much attention, as 

 the Micro-Lepidoptera. 



In British India alone a large collection could be made, and 

 these remarks apply also to the preceding and following divisions.
