120. Prochasma SCISSIYESTIS sp. n. 



(^ 21 mm. ; 9 24 mm. 



Head white, with a few black dots. Palpus short and stout ; 

 blackish with pale tip. Antennal pectinations much shorter 

 than in the typical species. Thorax above black ; metathoracic 

 crest lower than in the other species, the admixture of metallic 

 scaling perhaps less strong. Abdomen white, with black 

 irroration and clouding (lost in type). 



Fore wing with the coincident vein (SC^'^j well free; fovea 

 large; white, finely irrorated with black; some blue-grey 

 scaling between postmedian and subterminal lines, except at 

 hind margin ; a highly irregular- vandyke-brown cloud occupying 

 basal area and cell and forming a posteriorly attenuated band 

 just proximally to the postmedian ; cell-mark small, black, 

 inconspicuous ; lines marked by costal spots, otherwise 

 obsolescent ; antemedian fairly direct, bounding the basal area ; 

 postmedian gently incurved between R^ and M", extremely 

 oblique inward from M" to fold, then slightly oblique outward; 

 subterminal dentate, almost obsolete in posterior half, in 

 anterior edged proximally and distally with black shading. 

 Hind wing with termen scarcely at all crenulate, very slightly 

 sinuate inward between SC^ and R^ ; white with fine black 

 irroration (weakest costally) ; abdominal edge tinged with 

 brown; cell-spot and postmedian line distinct, the latter little 

 bent, punctuated on the veins; subterminal indicated by 

 some proximal shading. 



Fore wing beneath more suffused anteriorly, the Vandyke 

 shades replaced by black-grey ; hind wing nearly as above.
