ACIDALHD.-E—ACIDALIA. 29 



central spot faintly indicated, followed by extremely indistinct 

 stripes as on the upper side. Body pale grey-brown ; legs 

 yellowish-brown. 



Apparently not variable, except perhaps in size, those 

 taken here, so far as I have seen, being certainly much 

 smaller than German specimens. 



On the wing at the end of -June and in July. 



Lak\a and I'nw insufhcieutly described, ajjparently not 

 observed in this country. 



This species has been included in the British Fauna for a 

 very long period ; and was so recorded and described by 

 Haworth and the subsequent writers ; and it was not till the 

 year 18tJ7 that the curious discovery was made that the species 

 so recorded was not u^seata at all, but a closely allied species 

 then known as A. interjectaria, Bdv.. now as A. dilidar'ui, 

 Hub. Thus A. osscnta disappeared from our lists for twenty- 

 five years. But in the years 18'Jl and 1892 specimens were 

 taken by Mr. A. J. Hodges, in the Isle of Wight, of a small 

 moth which when examined in the latter year ])roved to be 

 undoubtedly belonging to the genuine A.usscata, Fab. .Schiti'. 

 as now tlescribed, though decidedly smaller than those from 

 the Continent, and scarcely so brightly red on the costa. In 

 this one locality, upon some cliffs overlooking the sea, it has 

 been taken in subsequent years by Mr. Hodges, and quite 

 recently by the Rev. C. T. Grutwell. To this extreme 

 southern spot it seems to be quite limited ; and it may, I 

 think, be taken for granted that any records elsewhere in the 

 British Isles merely arise from perpetuation of the old error, 

 and refer to the next species. Abroad the present species 

 seems to be very widely distributed in Europe, and in 

 Northern Africa, and Bithyuia.
