under his curatorship. He thought that the members would 

 be interested to see them, as Newman, when he wrote the 

 life-history of B. perfumaria (' Entom.,' 1865, pp. 246-9), 

 appeared to have relied entirely upon larval characters and 

 habits, and had not, so far as he had been able to ascertain, 

 published any proper description of the imago. Knaggs 

 (' Ent. Ann.,' 1866) threw very little further light upon the 

 question. But for some reason an impression appeared to 

 have got abroad that B. perfumaria was a form distinguish- 

 able from the type by its appreciably darker coloration. He 

 thought, however, that a comparison of the series exhibited 

 would show that there was no greater colour variation 

 between Newman's specimens of B. perfumaria and B. 

 rhomboidaria than was generally to be found within the 

 limits of a brood reared from typical parents. The black 

 form exhibited appeared to belong to quite a different race 

 which has been known to occur in one restricted locality in 

 Kent for upwards of twenty years past. As compared with 

 the typical form, with which it occurs, it is rare, nor does it 

 appear to have shown any comparative increase in numbers 

 in recent years ; but if, as occasionally happens, a black 

 female is taken and bred from, the progeny consisted of 

 both forms, the proportion of black specimens being gene- 

 rally somewhat in excess of the typical in point of numbers. 

 He was not, as a rule, in favour of varietal names, except 

 in the case of .very distinct and recurrent forms, but he 

 thought in the present case the black form might conveni- 

 ently be referred to as ab. nigra. 



Mr. Adkin also exhibited a series of Zygcena (Anthrucera) 

 achillece taken in Argyllshire, 1907. 



A series of Xola albulalis captured in East Sussex in July 

 last, together with Chattenden (Kent) specimens for com- 

 parison. 



A variety of Chrysophauus pJihvas in which the hind-wings 

 had a coppery shade, and the red marginal band was repre- 

 sented by narrow bars; also one of Aglais (Vanessa) urticce in 

 which the apices of the fore-wings were streaked with pale 

 blue-grey, and the blue lunules of the hind-wings were 

 abnormally large. 



A case containing pupa-skins of several of the Sesiidae in 

 situ, including those of Sesia scoliiformis, S. culiciformis, S. 

 andreuiformis, S. asiliformis, and S. ichucumoniformis; also 

 cocoons, etc., of some other lepidoptera, viz. the resinous 

 nodules of Retinea rcsinella, including sections showing the 

 workings of the larva and others that had been appropriated
