4563. Cr ambus pascuellus, Linnaeus. 



Only three specimens seen to date, Yarmouth, June 18, 20 and 24, 1915. 



4564. Crambus girardellus, Clemens. 



One of the most beautiful of our small moths; the snowy white fore wings being 

 marked by a single longitudinal dash of golden yellow. During the last half of July, 

 1915, 1916, and 1917, this species has been found along low grassy land bordering 

 brooks about Truro. It is far from common here, however, and I have not seen it 

 elsewhere. 



4565. Crambus leachellus, Zincken. 



Very common about Yarmouth Co., and in and about Truro, during July, Aug- 

 ust and September. Several specimens in the writer's collection have the narrow 

 white line over the end of the white stripe in the fore wing entirely obliterated, and 

 the continuation of the white stripe beyond the sub-terminal line is practically 

 missing. 



4566. Crambus unistriatellus, Packard. 



Easily recognized, as the name indicates, by the single, continuous, pure white 

 stripe, running throughout the entire length of the otherwise golden-brown fore- 

 wing. 



On July 30, 1912, two specimens were taken on a salt marsh at Arcadia, Yarmouth 

 Co. None were seen again until July 12, and 13, 1917, when several were observed 

 on a sphagnum bog at Argyle. 



4568. Crambus dissectus, Grote. 



Only one specimen seen. On a sphagnum bog, Argyle, July 13, 1917. 



4569. Crambus bidens, Zeller. 



Only three observations to date, Truro, July 19, 1916, July 25, 1917, and Cape 

 Sable Island, July 18, 1917. 



All differ from the description in Fernald's monograph, by having the white 

 stripe of the fore wing streaked with brown, and in having the hind wings smoky. 



4574. Crambus albcclavellus, Zeller. 



One specimen, Yarmouth, July 16, 1912. Since found not uncommon about 

 Truro, July, 1915, and 1917. 



4575. Crambus agitatellus, Clemens. 



Not uncommon about Yarmouth, June and July, 1913, 1914 and 1915. The 

 writer's specimens are much darker than those in the Fernald collection, the ground 

 color of the wings being dark brown, approaching fuscous instead of nearly yellow. 

 This species has not yet been observed about Truro. 



4577. Crambus albellus, Clemens. 



Three specimens taken at Yarmouth, Aug. 20, 1914, seem to satisfy the descrip- 

 tion of this species, but all are so much rubbed, and so faintly marked as to justify 

 a factor of doubt as to their identity. 



4579. Crambus hortuellus, Hubner. 



One of the commonest species throughout the province during June, July, and 

 August. My Nova Scotia specimens were darker than other Eastern American, 

 or than the European specimens in the Fernald collection. But two Nevada spec- 

 imens are much darker than mine. Nova Scotia specimens are pretty constant in 

 shade of coloring. 



4580. Crambus perlellus, Scopoli. 



Apparently very common everywhere throughout the province. It is the spec- 

 ies which has the fore wings pearly white, unmarked by spot or line. Nova Sco- 

 tia specimens have much more smoky tint on both body and wings than the de- 

 scription in Prof. Fernald's monograph warrants
