Arthisma, n. g. 



Male. Fore wing elongated, somewhat narrow, apex acute ; ex- 

 terior margin oblique and angular in the middle, posterior margin 

 angular near the base ; costal vein extending two thirds the margin ; 

 first subcostal emitted at half length of the cell, second at one 

 eighth, trifurcate, the third being thrown off at one sixth from 

 base of second, and the fourth close to apex at one eighth from 

 base of third, fifth from end of the cell and slightly touching 

 third near its base ; cell long, rather broad ; discocellular slightly 

 bent near both ends, radials from the angles ; upper median from 

 above end of the cell, middle median from the end, and lower at 

 one half before the end ; submedian slightly concave near the base. 

 Hind wing short ; anterior margin much arched at the base ; exterior 

 margin very oblique, scalloped, and deeply cleft between the lower 

 median and submedian veins, the cilia fringing the margin on both 

 sides to the end of the incision ; abdominal margin long ; subcostal 

 vein looped to costal at its base ; cell very short, less than one third 

 he wing ; two subcostal branches from end of the cell ; disco- 

 cellular concave, slightly bent near its lower end ; radial from the 

 angle ; two upper medians at one fourth beyond end of the cell, 

 lower median at one half before the end ; submedian much undu- 

 lated ; internal slightly recurved, and apparently with a short second 

 inner veinlet lobed to it near the base. Body moderately slender, 

 abdomen long; palpi long, slender, ascending, second joint projecting

Arthisma scissuralis.

Male. Fore wing dark purplish reddish-ochreous, palest and 

 blotchy on posterior border ; crossed by a darker oblique zigzag 

 antemedial and a medial line, the latter bent below the reniform
