Lepidoptera from Southern Africa. 407 



the dentated yellowish discal line much larger ; secondaries 

 with brown band broader, pale discal band more distinctly 

 interrupted ; wings below not so much speckled with dark 

 brown ; front legs clothed with longer masses of hair. Ex- 

 panse of wings 3 inches. 



Ambriz (Monteiro) • Natal (Burrotvs). 



This species is clearly distinct from 8. chhrea ; the form 

 and pattern of the primaries is strikingly different. Mr. Mon- 

 teiro took a long series at Angola ; he says that it is very 

 common. It always flew into the house when he was at dinner ; 

 so that he gave it the name of "the dinner-moth." 



M. Guene'e has described a species from Senegal, which he 

 considers a variety of his 8. sipyla, of which he says : — " Je 

 n'ose en faire une espece se'paree, car elle differe a, peine clu 

 type." It may perhaps be my 8. Monteironis ; but the de- 

 scription scarcely suits it. 



Genus 67. Ophisma, Gue*nee. 



82. Ophisma croceipennis, Walker. 



Natal. 



The West- African representative of this species, noted by 

 Walker as " var. 7," is totally distinct, the transverse lines 

 on primaries being all undulated, and the black spots of secon- 

 daries united into a subcuneiform black patch. It may take 

 the name of Ojihisma rivularis. 



Natal. 



Genus 68. Ophiusa, Gue'ne'e. 

 83. Ophiusa proper ans, Walker. 



Genus 69. Grammodes, Guene'e. 

 84. Grammodes geometrica, Fabricius. 



Natal. 



It is difficult to distinguish this species from G. ammonia. 



Genus 70. Triganusa, Walker. 



85. Triganusa euproctisoides, Walker. 



Natal. 



This genus would, I think, be better placed next to Ophisma ; 

 but even there it does not look well ; it certainly ought not 

 to come between Grammodes and Trigonodes (which is where 

 Mr. Walker has put it in the Collection). The example taken 

 by Mr. Burrows has a second black spot on primaries, at 

 basal third of interno-median interspace.
