GERBATHA, Walker. 



Gerbatha ypsilon. (Plate XLVII. fig. 1.) 



Grey : primaries with a lilacine tint and speckled with black ; an irregularly sinuated 

 black line across the basal area ; a broad shining bronze-brown Y-shaped band across the 

 wing beyond the middle, its external branch and main stem traversed by a sinuated central 

 black line ; a dentate-sinuate submai-ginal dusky line with a white external border ; a mar- 

 ginal series of white-edged conical black spots ; three or four white costal dots towards apex ; 

 a white V-shaped marking at the infeiior extremity of the cell : secondaries bronzy brownish, 

 slightly darker at outer border ; fringe whitish, with a central dusky line ; body corresponding 

 in colour with the wings. Under surface sericeous, the markings for the most part obsolete ; 

 secondaries with well-marked discocellular spot and angulated discal line. Expanse of wings 

 1 inch 4 lines. 



Yokohama [Jonas] . 



Gerbatha angusta. (Plate XLVII. fig. 2.) 



Allied to the preceding species, but the primaries darker and narrower ; forked bronzy 

 band wanting ; the black lines, although similar in direction, differ in sinuation : the discoidal 

 markings generally outlined clearly in white ; a white spot below the orbicular spot ; other- 

 wise very similar. Expanse of wings 1 inch 5 lines. 



Yokohama [Jonas). 



Evidently much commoner than G. ypsilon.
