wings are equally black, with deeper black nervures, but on the 

 hind-wings is very often a slender, much scalloped, white subterminal 

 line. 



BoAEMiA EOBORARiA. — So far as I know this is the latest British 

 species to adopt the unicolorous black tint. In 1893 J saw in Mr. S. 

 J. Capper's collection six specimens of a most beautiful, smooth, 

 smoky-black, with nervures and the lunules of the hind-wings deeper 

 black. Since then Mr. Capper has obtained more specimens, one of 

 which he has most liberally added to my collection ; and informs me 

 that all were reared by a correspondent, in whom he can rely, in the 

 Midland Counties ; but for obvious reasons the exact locality is not 

 revealed. The statement of the captor is as follows:— "I have taken 

 the oi'dinary form of rohoraria for many years, and once, about eight 

 years ago, a black one, which was badly rubbed. In 1892 a second, 

 from which I bred those you have. I think it was at the end of June 

 when I took it — a fine female — at pest on the trunk of an oak. The 

 ova hatched in the middle of July, and I fed them through the summer 

 to the end of October, when they began to hide away. In January I 

 found some of them wandering about for food, so I got them young 

 twigs of oak, and scraped the bark. Some of them ate the bark, but not 

 many, and I only managed to rear about twenty to the pei'fect state, 

 some of them being black. Two of these I kept and bred again, both 

 being black ones, but I could only rear about thirty, of which you 

 have the black ones, except one pair, and from these I have only pulled 

 through fifteen larvae, so I fear that I shall lose the brood." Besides 

 these I hear of only one British specimen, and it will be for future 

 observation to show whether this handsome aberration establishes and 

 extends itself. Like B. repandata it usually shows a whitish sub- 

 terminal line on the hind-wings. 



Venusia cambeica. — Of the unicolorous blackish form of this 

 pretty species I find no record in any descriptive work or magazine. 

 It is, however, mentioned in the Proceedings of the South London 

 Entomological Society for 1888, the specimens having been obtained 

 from the neighbourhood of Shefiield. In 1890 four more specimens 

 obtained from the same locality were exhibited before the same Society 

 by Mr. Percy Bright. 



There is one in the collection of the late Mr. F. Bond ; one in 

 that of Dr. Mason ; and a very few more scattered in various cabinets. 

 This variety is not black, but blackish-grey, with darker nervures, and, 

 like the previously noticed species, has lost its typical markings. At 

 present it is only a very local aberration.
