Genus DIGAMA. 

 Digama, Moore, Catal. Lep. E. I. C. ii. p. 298 (1858); P. Z. S. 1878, p. 4. 



Forewing narrow : first branch of subcostal long, free ; second at a considerable 



distance before end of the cell, trif urcate ; fifth from near end of the cell, curved upward 



and looped to third at one-third its length ; radial from end of the cell ; discocellular 



nearly erect ; median vein four-branched, upper from end of the cell, second and third 



from angles near its end : hindwing short, with two subcostal branches beyond the cell ; 



discocellular curved outward, oblique ; four median branches, three upper from end 



of the cell. Below the submedian vein on the underside of the forewing is a short 



longitudinal cavity, along the upper edge of which projects a raised transversely 



scabrous narrow bar, and on the upperside of the hindwing is a short transverse 



outwardly curved raised scabrous bar, so placed that, by the motions of this wing, 



it evidently plays across the longitudinal bar on the forewing, and produces a stridu- 



lating sound. 



DIGAMA INSULANA (Plate 100, Fig. 3, $).

 legs black banded above ; palpi with terminal black bauds. Underside paler ; both
