Some apparently new Noctuidae from Sumatra, etc. 443 



Fore wing green with a brown half-band between subbasal and 

 antemedial lines, and the terminal area (from the postmedial line) 

 predominantly brown ; lines black, double, waved or slightly dentate 

 and excurved ; subbasal from costa to M, followed by a large black 

 spot before hindmargin ; antemedial from two-sevenths costa to two- 

 fifths hindmargin ; orbicular a black-outlined white spot ; reniform 

 8-shaped, black-outlined, with a white spot in each division; medial 

 line with the inner line thick and black, from near middle of costa 

 to middle of hindmargin ; postmedial from four-sevenths costa to three- 

 quarters hindmargin, followed on anterior half of wing by a glossy- 

 brown area only interrupted by terminal white spots and by the green 

 subterminal line, which is much bent inward and proximally dark- 

 outlined before SC 5 ; on posterior half of wing the brown shading is 

 reduced to a more or less irregularly narrow band near postmedial 

 line, and a spot at tornus : a black, dagger-like streak in fold from 

 postmedial line to termen, varying in breadth and sometimes interrupted 

 at middle ; some large interneural black-outlined white spots on 

 posterior half of termen ; fringe chequered brown and green, with the 

 brown predominating on anterior half of wing. 



Hind wing yellow, with a diffused discal streak and a somewhat 

 broad dark border (usually angled proximally at M 1 ), narrowing to a 

 point at anal angle, where there are two pale-green spots, the second 

 proximally succeeded by a brown spot ; fringe brown, chequered with 

 pale-green. 



Underside of both wings pale ochraceous-yellow, shading to greenish- 

 white towards termen, with two diffused, waved postmedial lines and 

 chequered fringes. Hind wing with slight medial bar at costa, and 

 discal streak ; fore wing with very slight antemedial line and some post- 

 medial dark clouding.

Seems to agree perfectly in structure with biformis Walk. {Dandaca 

 biformis Walk., xv, 1671 [1858] [Sarawak]), the type of Belciana 

 Walk., except in the more strongly developed abdominal crests, which 

 agree better with eurychlora Walk. {Dandaca eurychlora Walk., 1670 

 [1858] [Canara]), the type of Donda Moore. In the hind wing also 

 this species more nearly resembles D. eurychlora and D. ornata Moore 

 {Proc. Zool. Soc, 1883, p. 23, pi. iii, fig. 3 [Bombay]) than any Belciana
