wing. Willi the exception of one specimen, taken at liglit, there are 

 always very distinct shades of oHve green or l)rown of varying intensity on 

 different parts of the wing and on the collar. In some specimens a broad 

 central band of rich olive brown is the most conspicuous mark. Pupation 

 commenced during 1904 on June 25th. The duration of emergence 

 seems short, and all my specimens, numbering nearly sixty, emerged, 

 usually between 4 and 9 p.m., between July 30th and Aug. 4th. In 1902, 

 the only other time I have bred it, the few I had hatched in about the 

 same time, but a week later. Only two specimens have been taken 

 besides those bred, at light, Aug. i6th and Sept. 27th, 1903. Both are in 

 perfect condition, and that taken on the earlier date is normal. The Sept. 

 27th specimen shows such very slight traces of the olive shading that I at 

 first overlooked the existence of any, and felt sure it was a different 

 species. However, it agrees in every other detail with specimens subse- 

 quendy bred. An attempt to bleach out the olive shade from bred speci- 

 mens by long exposure to sunlight has failed, but it may be that exposure 

 to the weather when alive may have this effect. The apparent retiring 

 habits of the insect would account for its otherwise good condition at so 

 late a date. 



346. Lithomoia germana, Morr. — An extreme rarity until 1903 and 

 1904, during which seasons it has been common at treacle. Middle Aug. 

 and Sept. 



347. Xylina amanda, Smith. — Rare at sallow blossoms. End April 

 and early May. I formerly had this as petiilca, but it is not compared 

 with that species (signosa) in the description. Described partly from 

 Calgary material, and appears to be widely distributed over the continent. 

 The type is from Winnipeg, and is at Washington. The figure given with 

 the description in Prof. Smith's Revision of Xylina (Trans. Am. Ent. Soc, 

 XXVII., pp. 1-46, Aug., 1900), gives a good idea of the species, though 

 the left wings of that specimen are in a bad light. I have the same 

 species from Aweme, Man., sent me as contenta, but not agreeing with 

 figure or description of that in the Revision. 



348. X. fagina, Morr.? — A ^^ , taken by Mr. Gregson at Lacombe, 

 Alta., on September ist, 1900, has'been doubtfully so referred by Prof. 

 Smith, who writes : " A specimen from Cartwright, Man., is intermediate 

 between this and novmaX fagina. I am not so certain that this will not 

 prove new when plenty of material is at hand." He had seen the speci- 

 men before and labelled it " holocinerea ?" A similar 9 was taken here
