28 EUPITHECIA JASIONEATA. 



stiff bristle. Each segment is subdivided by six deep 

 transverse wrinkles, the first four wider apart than 

 the other two ; the segmental divisions are very 

 deeply cut, the end of each segment swelling' out in 

 breadth beyond that of the beginning of the next ; 

 the surface of the skin being thickly covered with 

 granulous points ; the bulbs of the flask shapes or the 

 barrels occupy but little more than the hinder half, if 

 any, on each segment, so that the difference between 

 the marks on this larva and those on the larva of 

 E. campanulata is one of proportion. 



Subsequently Mr. Ficklin informed me that he found 

 these larvae on the plants growing at an elevation of 

 several hundred feet above the sea at Lynton, North 

 Devon. (William Buckler, 26th September, 1879 ; 

 Note Book IV, page 6.) 



Some three years ago I received from Mr. Ficklin, 

 of Keynsham, near Bristol, specimens of a Eupithecia, 

 Avhich he had bred from larvae taken the previous 

 September in North Devon, feeding in the seed-heads 

 of Jasione montana. At first sight I was disposed to 

 consider them a variety of Eupithecia castigata, and in 

 this view Mr. Buckler, who also saw the specimens, 

 concurred. I forbore, however, to give any definite 

 opinion till I had seen the larvae. 



The same autumn Mr. Ficklin again took the larva 

 in North Devon, and very kindly sent specimens both 

 to Mr. Buckler and myself. We at once saw that 

 they bore no likeness whatever to the larva of E. cas- 

 tigata, but, though smaller and stouter, most closely 

 resembled that of E. campanulata. As, however, the 

 perfect insect was totally distinct from the latter 

 species, I felt convinced it must be a species new to 

 Britain. 



Through the kindness of Mr. McLachlan the per- 

 fect insect has recently been carefully examined by 

 Herr C. Dietze, of Baden-Baden, who probably knows 

 more about the Continental Eupithecix than anyone 

 else. He is unable to identify it with any known
