408. Atitographa Sackeni, Grt. — Rare. A ^ and two 9 ? are 

 labelled July 12th to 25th, taken in different years. At light, and flying 

 in sunshine. The ,^ bears Dr. Ottolengui's label. As a matter of fact, 

 this and the preceding species were returned to me bearing the wrong labels. 

 The error was quite obvious from the figs, in Dr. Ottolengui's paper, so I 

 reversed them. His letter to me at the same time convinced me as to the 

 lapsus. A $ which hatched out on July 23rd, 1902, from a larva found 

 feeding on Potetitilla fruticosa a few weeks previously, has a broader black 

 border on secondaries, and differs slightly in the sign, but otherwise looks 

 the same. 



409. A. Snowi, Hy. Edw. — I have three specimens dated July ist 

 to 1 2th, from the "Billing's Mill" locality, where it seems to fly in com- 

 pany with Syngrapha ignea, but in fewer numbers. I never took the 

 species until 1903. Dr. Dyar gave me the name. Closely allied to the 

 preceding species, and similar in pattern. Comparing them, Dr. Otto- 

 lengui says in his paper concerning Snoivi: " It is smaller, the apex of 

 the wing is much less produced than in Sackeniz-wA the colour is different. 

 As words do not adequately describe colour, let me resort to comparisons: 

 The colour scheme of Snowi is the same as in simplex^ the browns and 

 reds being identical in shade. The coloration of Sackeni is nearer to, but 



not exactly the same as ampla A spot at the base of the costa is 



orange in Snoivi ; it is more sagittate in shape and very pale yellowish in 

 Sackeniy In my specimens Snowi has a dark apical shade, which 

 Sackeni lacks. Both are figured in Dr. Ottolengui's paper. 



410. Syngrapha devergens, Hbn. — A splendid specimen from Mr. 

 Bean, taken at the station level at Laggan about twelve years ago. was so 

 named for me by Dr. Ottolengui, but is not now in my collection. Mr. 

 Bean gave me to understand that it was common at Laggan. I have a 

 badly-rubbed specimen of the same species taken close to the station there 

 on July 17th, 1904, by Mrs. Nicholl. It bears some resemblance to a 

 miniature ignea, but though the differences are obvious enough between 

 good specimens, it is no use my trying to locate them with only one very 

 bad specimen of devergens at hand. It is not in the least like Dr. Hol- 

 land's figure of the species, which bears a suspicious resemblance to Dr.
