sentially from those from Maine. Caribou Island, common, but not 

 found northward. It is evidently not a member of the Arctic fauna. 



Grapliolitha nebulosana n. sp. 



Body blackish, wings clouded, dusky ; head, palpi and thorax, uni- 

 formly dull brown, abdomen becoming more cinereous, wings very 

 uniformly dusky, with no lines or spots, but a few scattered black dots 

 on the costa, and dusky scales on the middle of the wing, gathered 

 into an obscure, dark spot, which has a slightly tawny tinge, and 

 forms a short, oblique, dusky band. The hind wings are paler than 

 the fore wings. The two anterior pairs of legs are dusky, the tarsi 

 ringed with white, while the hind tibia3 and tarsi are whitish silvery. 



Length of the body .28 ; fore wing .36 inch. 



It is not infrequent at Strawberry Harbor. July 26-30. 



It may be recognized by the absence of very distinctive markings 

 on the fore wings, and by the unifoi-mly dusky body. A discal dot is 

 sometimes present, communicating by a dark oblique line with a 

 costal dot, and there are a few tawny scales on the apex. Fringe 

 dusky, with a mesial white line, on the hind wings white. 



TINETDiE. 

 Grelechia trimaculella n. sp. 



S . Blackish, especially the thorax, and the costa towards the apex 

 of the fore wings. Front cinereous, palpi black above, beneath cin- 

 ereous, terminal joint entirely black, wings dark cinereous with black- 

 ish scales ; at the base, a narrow white line starts from the costa, and 

 turns outwards at a right angle, following the submedian vein, and is 

 then bent downwards at a right angle, terminating just below the 

 submedian. In the middle of the wing is a short longitudinal white 

 stripe, ending near the dark, obscure, discal dot. On the outer front 

 of the wing is a costal and internal white, conspicuous straight spot, 

 which is white at the end near the middle of the wing. Fringe 

 dusky ashen, or whitish ; the hind wings are of the same ashen hue. 

 Legs blackish, annulated with white, hind tibiae pale within. 



Length .26 ; fore wing .84 inch. 



Strawberry Harbor, the last of July. 



In one specimen the fringe is whitish ashen, in the other it is dark, 

 and the white markings are much more distinct. Beneath both wings 

 are concolorous with the upper side of the secondaries, with a pale 

 spot on the outer fourth of the costa.
