'38 LEPIDOPTERA. 



2'J-th June 1872, near Dover, flying in the sunshine, and is 

 now in the collection of Mr. W. H. Tugwell. Besides this, 

 a worn specimen is said to have once been taken in Yorkshire. 

 These appear to be the only cases in which this species has 

 been found at large in this country, and they furnish but a 

 very slight claim to naturalisation. There appears, however, 

 nothing in its habits to forbid its occurrence here, since it is 

 found in Central and Southern France, Holland, Belgium, 

 North and South Germany, as well as in Northern and West- 

 ern Asia and North and South Africa. Probably it requires 

 more and hotter sunshine than these Islands usually afford.) 



(Naclia ancilla, L. — A neat, rather plain species with 

 narrow forewings, brown with a row of three white spots 

 beyond the middle, hind wings yellow with brown base and 

 border. A specimen, said to have been captured near 

 Worthing, Sussex, was exhibited at the Entomological Society 

 in 1867 by the late Mr. E. Newman. No other British 

 specimen is known. This species is said to be found, locally, 

 in dry flowery woods in France, Germany, Belgium, Italy 

 and in other parts of Southern, and also Eastern Europe.) 



The two last mentioned (casual) species are allied to the 

 Zijgctnidce, though in the case of Nadia the thickening of the 

 antennfB is extremely slight, and it appears to lead towards 

 the Lithosiclce, one of the families of the Bomhyccs. Another 

 family of very large extent — the Agaristidoe — with sphingi- 

 form antennfo, shows a wonderful series of relationships with 

 Zyga:nidce, Lithosida\ and Ardiida', and the habits of its 

 species are mainly diurnal ; while another — Castnia — seems 

 to imitate some of the broader winged Nodua'. Indeed the 

 relationships — if any — in these groups appear often to run in 

 parallel rather than in direct lines, and there is very small 

 apparent affinity, except in the narrowness of the wings, 

 between the species just described and those next to be dealt 

 with.
