middle, some black irregular patches on the upper half 

 of the wing ; near the base a black cross with equal arms 

 on the outer edge of the basal third ; a conspicuous black 

 V-shaped mark, with irregular dentated edges about the 

 middle, reaching the costa before and beyond the middle, 

 and the dorsal margin scarcely beyond the middle ; three 

 black spots on the dorsal margin, one near the base, one 

 betweeen the cross and the V-shaped mark, and one 

 near the anal angle ; a small black costal spot equi- 

 distant between the arms of the V and some small 

 black marginal spots around the apex and the anal 

 angle, with an irregular thick black streak extending 

 inwards from below the apex. Legs white, with several 

 black annulations. Expanse, 26 mm. 



ERETMOCERA, Zeller. 



It is remarkable that Mr. Walker, in characterising 

 the genus Exodomorplia (Cat. Lep. Het., B. M., xxix., 

 p. 833), should not have been reminded of Professor 

 Zeller's genus, Eretmocera (Microp. Caffr. ; Kong. Svensk. 

 Vetens. Akad., 1852, p. 98), which was established to 

 include several allied species occurring in the same 

 district as those described by Mr. Walker, and in some 

 cases apparently identical with them. I am indebted to 

 Mr. A. G. Butler for having called my attention to the 

 fact that the genus Stamtonia, Staud. (Stet. Ent. Zeit., 

 1859, p. 250), is the same as Exodoinorplia , Walk., in 

 which case it must also yield to the priority of Zeller's 

 Eretmocera.

Prof. Zeller describes what he regards as two varieties 

 of this species, and points out the differences between 

 them, as follows :
