12. Semaeopus luridata subrugosa s\ibsp. nov. 



cj, 26 mm. Shghtly shorter-winged than I. luridata Warr. (Nov. ZoOL. 

 xiv. 219), from S.E. Peru. Above otherwise scarcely distinguishable, the outer 

 line of the forewing not so deeply inbent, the dark terminal blotch between the 

 radials consequently less elongate proximally. Hindwing beneath, except a 

 pale distal border of 2 mm. width, covered with rough orange-rufous scaUng.
