398 LEPIDOPTERA. 



The moth hides during the day among the low growing 

 herbage — stunted heather, bog-asphodel, cranberrj', and 

 short grasses and sedges — on the boggy portions of heaths or 

 the edges of fens, but flies up if disturbed by a passing foot- 

 step, to hide again at a few feet distance. It flies naturally 

 at sunset and after. It is said to be unusually regardless of 

 weather and to fly willingly on windy nights. Formerly it 

 was common in the fens of Cambridgeshire and Huntingdon- 

 shire — Burwell Fen, Whittlesea ilere. Holme Fen — but 

 apparently not in Wicken Fen, for since the draining of the 

 former fens it seems to have died out of that district ; and 

 so far as I can ascertain it has never been seen in those of 

 Norfolk. It is now a scarce species, but a few have been 

 captured from time to time near Arundel, Sussex; in 

 Wolmer Forest and at Lyndhurst, Hants ; and at Bloxworth 

 Corfe and Studlaud, Dorset ; more recently Mr. G. T. Porritt 

 has discovered it at Thorne Moor, Yorkshire. With the 

 exception of an old report of several specimens from a small 

 moss a few miles from Crewe, Cheshire, these are apparently 

 all its known localities in these Islands. Abroad it is found 

 among the mountains of France, in Holland, Northern 

 Germany, Switzerland, Catalonia, Livonia, and Finland. 



Genus 11. ACIPTILUS, 



Antennae simple but the basal joint thickened; palpi 

 short, slender, the final joint depressed ; fore wings cleft to

 apart and without lateral angles, or tufts ; hind wings also 

 cleft in long linear sections broadly ciliated but without 

 tufts. Wings rather lax and drooping at the tips. Legs 

 very long. Abdomen rather short. 



We have five species — readily discriminated. 



A. Fore wings white. 



B. Fore wings slightly dotted witli black.
