92 THE CANADIAN ENTOMOLOGIST, 



Maine would prove the existence of two good species, especially if a 9 

 form should be found constantly different from the $ of Aiieniana. 



The fore wings of the $ types of Aiieniana are yellowish-brown, very 

 finely and lightly reticulated with a darker shade of brown, an oblique fascia 

 from centre of costa in one specimen extends barely to cell, and in the other is 

 obsolete; on co?ta before apex is a faint indication of a spot. The hind wings 

 are immaculate, of a very light buff shade. Several of the Regina ^ $ 

 compare closely with the types, except that the central fascia is strongly 

 developed, continuing down to and disappearing just above the anal angle, 

 while the pre-apical spot is large and dark, and has a tendency to run into 

 a curved sub-marginal darker shade that involves the outer margin. The 

 balance of the $ specimens have distinctly grayish-brown fore wings, 

 with reticulations, fascia and marks the same ; but the hind wings are 

 fuscous, with the pale straw colour costal and apical borders finely reticu- 

 lated. I think it quite likely that this is the species referred to in a letter 

 from Dr. Fletcher (VII., 15, 1904) that is suspected of doing considerable 

 damage to the Populus tremuloides of the Northwest. I should like to 

 have given the name populaiia to this species, but find it impossible to 

 separate from Aiieniana with the material before me. 



Tortrix syniphoricarpana^ sp. nov. — $, 27 mm. Head and palpi 



grayish-tawny-brown, outer ends of scales and outer joint of palpi dark 



slaty brown ; thorax and front wing tawny-brown or grayish-yellow. An 



oblique, blackish-purple fascia from middle of costa to hind margin before 



anal angle, narrowest on costa; indented and partly interrupted on upper 



median vein, inner edge well defined, nearly straight but swelling out 



slightly in cell, with two very slight indentations, one at middle of cell and 



one on median vein, slightly concave below cell ; outer edge of fascia less 



distinctly defined, the dark colour becoming paler and approximating 



the ground colour ; indented between costa and upper median vein, below 



latter convex to before anal angle. A duplicate spot on costa half 



way between fascia and apex, somewhat triangular but rounded on inner 



edge, and is twice as wide on costa as fascial spot on costa, most intense 



on inner edge ; from lowest point of spot is a dark, outwardly curved, 



much broken line to anal angle ; several short, vertical reticulations 



between this line and outer margin, crossed by horizontal reticulations. 

 The balance of the wing is coarsely reticulated vertically, in the type 

 there being seven points touching the costa between base and fascia and 

 three between fascia and costal spot. Cilia tawny-yeilow. Hind wing 

 pale cinereous, clouded basally and dorsally with fuscous, and apically
