248 LEPIDOPTERA, 



food plant proved, very fortunately, not to be absent, though 

 it does not seem to have very speedily been found ; but in 

 1873 larvae were found in the same district by Mr. MoncreafE 

 and forwarded to Mr. Buckler, from which his description 

 and figures were made. In the following year it was dis- 

 covered at Folkestone, Kent, in some plenty ; and although 

 the original locality has been, as I understand, destroyed in 

 the course of erection of fortifications, the produce of the 

 newer locality has been so satisfactory that few cabinets are 

 without this exquisitely beautiful species. For my own series 

 I am mainly indebted to Mr. J. W. Downing. It is now 

 found along the chalk cliffs at Dover, St. Margaret's Bay, 

 Lyddon, and elsewhere in Kent, and should certainly be met 

 with in Sussex. The late Major J. N. Still had the good 

 fortune to take three specimens, two of which are now before 

 me, at light at Seaton, Devon, in 1889 and 1890, and one is 

 recorded at Axminster in the same county. This appears to 

 be the extent of its range, as at present known, in these 

 islands. Abroad it seems to be found all over Europe, except 

 the extreme North and South, also in Asia Minor, and the 

 mountainous regions of Central Asia. 



[D. compta, Fah. — A very pretty species, smaller than 

 the last, purplish-brown, abundantly marbled with fine black 

 lines and white dots, and having the whole centre of the 

 fore wings occupied by a broad, complete, white transverse 

 band, in which the two upper stigmata are faintly outlined. 

 Of this sj)ecies the late Mr. E. Birchall wrote in 1866: "A 

 pair of this species, taken in Ireland by Mr. Tardy, are in 

 the collection of Trinity College, but I am unable to indicate 

 the exact locality of their capture. The insect has long been 

 a reputed British species, and I confidently anticipate its 

 admission to our lists when Dublin collectors bestir them- 

 selves a little." Dublin collectors did bestir themselves, but 

 so far as this species was concerned, without result ; a few 

 years later, however, specimens were duly announced as
