darker dentate shading for postmedian, and in one specimen 

 with a dark grey cell-spot ; terminal line and fringe as in 

 the allies. Underside pale grey, the markings as in cultata, 

 but somewhat weaker. 



Huancabamba, N.E. Peru, 5000-6100 feet ; two $ $ . 



Probably a near relative of S. cultata, to which it is very 

 similar in markings, though its larger size and absence of 

 definite green colouring make it rather recall lichenea, Ob. 

 Et. Ent. vi. tab. iii. fig. 6 (Cidaria). It is certainly not a 

 local race of cultata, of which I have a perfectly typical 

 example from Huancabamba. Spargania schistacea, Warr. 

 Nov. Zool. xi. p. 77, is also related, but much darker. 



Spargania ruptifascia, sp. n. 



<J. 40-42 mm. — Extremely similar to Spargania lichenea, 

 Ob. ( = cenizata,Do%n. Le Nat. 1893^p.28, nov.syn.), differing 

 as follows : slightly larger ; face somewhat more ochreous 

 (in lichenea it is nearly white), the palpus more minutely 

 tipped with white; fore wing with the dark line from two- 

 sevenths costa much less angled in cell, but on the other 

 hand with a strong indentation on submedian fold which is 

 wanting in lichenea, median fascia still less clearly defined 

 than in that species, forming a small dark patch at costa and 

 another from inner margin to submedian fold, in the middle 

 of the wing scarcely indicated except by the zigzag lines 

 which bound it, the white band beyond the postmedian 

 rather clearer, broad, the olive shade which follows it broader 

 than in lichenea, reaching to the subterminal, the costal dark 

 markings in distal area stronger, subterminal not strongly 

 toothed basewards on SM 2 ; hind wing more varied, the 

 inner-marginal area being broadly shaded with grey, the 

 costal and apical area whiter, cell-spot distinct ; underside of 

 hind wing with stronger cell-spot and better developed post- 

 median line. 



Huancabamba, N.E. Peru ; two <$ $ . 



The above comparison has been made with four <$ $ of 

 lichenea from the same locality, and there seems no room to 

 doubt that the differences are specific, not varietal. In this 

 form of lichenea the hind wing is white ; but I have a speci- 

 men before me from W. Colombia in which, as in OberthuVs 

 figure, it is uniformly greyish, while it has more of the dark 

 markings, thus in part forming a transition between the two 

 Huancabamba species ; emphasis therefore should be laid 

 not .on the depth of colouring, but on the palpus and the 

 course of the lines on the fore wing.
