Genus NISI A. 

 Nisia, Melich. Horn. Faun. Ceylon, p. 53 (1903). 



Type, N. atrovenosa, Leth. 



Distribution. Oriental Region. 



Dr. Melichar diagnoses this genus as follows : — " Similar ^to 

 Kermesia by structure of head, but especiall}^ differs by the 

 narrower tegmina and by the direction of the strongly prominent 

 and thickened veins in the apical area, which number only five,, 

 and of which the second and fourth are forked ; in Kermesia 

 these veins are always eight or nine, partly simple and partly 

 forked terminal veins ; other characters as in Kermesia." 



Of the above characters, from the material before me, I cannot 

 describe the fourth apical vein of the tegmina as forked, at least 

 in the specimen I identify and figure as N. atrovenosa, Leth., 

 which Melichar gives as the type of his genus.
