THE CANADIAN ENTOMOLOGIST 85 



species and is followed in this by Warren in Seitz. Macrolep. Palaearc. Noct. 

 who makes no mention of u-aurcum as being Palaearctic. It would almost seem 

 as if European lepidopterists had agreed that the locality 'Dalecarlia,' given by 

 Guenee was erroneous and that the name u-aureum was based on Greenland 

 or Iceland specimens ; I have seen, however, no published notice to this effect. 



Ottolengui (1917-, Ent. News XXVIII. 29) treats of vaccinii and its 

 synonymy but makes no mention of arctica Moesch. 



The identity of u-aurenui and groenlandica being in doubt I am obliged 

 to leave them out of consideration for the present; if Aurivillius be correct 

 Guenee's name will take priority ; in the meantime the species should be known 

 as arctica Moesch. with vaccinii Hy. Edw. as a subspecies of doubtful value from 

 New Hampshire and possibly adjacent mountain peaks. 

 Syngraplia diasema borca Auriv. 



A single 9 specimen corresponds excellently well with Aurivillius' des- 

 cription and figure (op. cit. 17, PI. 1, fig. 8) ; this race is said to differ from 

 the type form from Northern Europe in the distinctly yellow coloration of the 

 central area of secondaries with moderately broad smoky border. I have al- 

 ways been inclined to associate a form found in the Rocky Mountains of 

 Canada with borca; this same form has recently been treated as a new species 

 by Dr. Ottolengui (1919. Jour. N. Y. Ent. Soc. XXVII, 121. PI. X\', fig. 2) 

 under the name divcrsigna. With a Paratype and a series of five males from 

 Nordegg, x^lberta. before me, I have made a careful comparison with the Labra- 

 dor specimen and fail to find any characters which would warrant specific 

 distinction; the Alberta specimens are slightly smaller and the yellov,- of secona- 

 aries somewhat brighter and if desired the name divcrsigna Ottol. may be re- 

 tained to designate the Rocky Mountain race ; for the Labrador and Arctic race 

 which is certainly easily separated from diascuia by the color of the secondar- 

 ies Aurivillius' term borea should be used and the synonymy would thus stand.

Gynacphora rossi Curt. 



One pair of this well-known Arctic form. 



Geometridak. 

 Acidalia frigida>-ia Moesch. 



A series of this well-known form captured July 12th-20th shows con- 

 siderable variation in the distinction of the transverse lines which at times 

 become almost lost in the general gray ground-color. 

 Carsia paludata labradoriata Moesch. 



One specimen. 

 Dysstroma citrafa Linn. 



A couple of rather worn specimens taken 23rd August. These were of 

 the dull gray form with slight ruddy subterminal suffusion and with median 

 band rather paler than the remainder of the wing, due to less heavy sprinkling 

 of gray, scales. This appears to be the usual form in northern localities.
