396 LEPIDOPTERA. 



This species is one of our rarest, and scarcely anything is 

 known of it in this country. It was included as British in 

 his Manual, by the late Mr. H. T. Stainton, on the evidence 

 of a specimen taken in Norfolk by Mr. Farr more than half a 

 century ago. This specimen has been long in the collection of 

 the late Mr. Jenner Weir. Mr. George Bird has obliged me 

 with a note on this matter found by him in the diary of the 

 late Mr. Farr, of Yarmouth, as follows : " June 17, 1842, took 

 two specimens of Pterophorus trkhodactijbis in a wood by Sir 

 John Leathes's boathouse, at Herringfleet ; beaten out of 

 alder bushes by me and Charles Paget." There is little 

 doubt in my own mind that this entry referred to the present 

 species, since Pt. trichodad ijl us is not known to have occurred 

 with us. If so, the destination of the second specimen is 

 unknown ; ^Ir. Bird, who possesses Mr. Farr's collection, 

 has not ever had it. Another British specimen is i-ecorded 

 as captured at Glen Tilt, Aberdeenshire, in 1874, by Sir 

 Thomas Moncrieff; this was confirmed more recently by 

 Mr. Stainton, and Dr. F. B. White states that another was 

 captured in the same locality. Mr. J. B. Hodgkinson had a 

 specimen said to have been taken by a working collector iu 

 Cumberland ; and Mr. N. V. Sidgwick informs me of the 

 capture of several specimens in Gloucestershire. This 

 appears to be all the evidence available of its existence 

 in these islands. Abroad it is found throughout Central 

 Europe, and in Denmark, Sweden, Livonia, the northern 

 half of Italy, Dalmatia, and Armenia.
