maculation but differs from all other related forms b^' the shading just described. 

 The secondaries are white. 



The species seems not rare and has been recorded from Los Angeles County, 

 Nevada County, and Sierra Nevada, California. 



It expands not quite one and one-half inches. 



Acronycta tritona Hbn. 



This is even shorter and more obtuse-winged than maustietn, with very dark 

 blue gray primaries and dull, smoky yellowish secondaries. The t. a. line is 

 practically wanting, the median shade is marked over the costal area, and the t. p. 

 line is distinct across the wing, outwardly shaded with black and crossed opposite 

 anal angle by a conspicuous black dash. There is a short black streak which 

 tends to become furcated. Both orbicular and reniform are incompletely marked. 



This is a wide-spread though hardly a common species : it ranges along the 

 Atlantic Coast from Maine to Florida and has been reported across the country 

 to Portland, Oregon, and the Pacific Coast generally. I have no Californian 

 examples myself and no definite localities within that State are reported so far as 

 I know. 



The larva; feeds on Vaceiniuni. 



Acronycta quadrata Grt. 

 This is a striking species, expanding about l.TS inches, broad-winged but 

 with distinct apices, very pale bluish gray in color, with distinct maculation and 

 conspicuously contrasting black marks as follows : a broad basal streak, terminat- 

 ing against basal line ; a quadrate patch between orbicular and reniform, a short 

 broad streak from the outer portion of t. p. line nearly to hind angle. The t. p. 

 line is outwardly shaded with black, and the median shade is diffuse and brownish. 

 Altogether a very easily recognizable and unmistakable species. 



I have only one Californian example, without date or definite locality, and no 

 definite records as to distribution within the State seem available. In British 

 Columbia and in Alberta it occurs in July and seems not rare. 



Acronycta liturata Sm. 



This is a dark ashen gray species, the primaries washed with smoky blackish, 

 the secondaries white. The wings are rather elongate, of moderate width only, 

 and the apices are well marked but not drawn out. The normal maculation is all 

 present but obscure and diffuse, a blackish shade extends through the submedian 

 interspace the full length of the wing, and a less obvious shading extends outward 

 from the orbicular. The latter is characteristic, round, pale, with a round, dark 

 central spot. The species expands nearly two inches and is very readily recog- 

 nizable. 



It is perhaps a question whether this species actually occurs in California; 

 but I have seen it from Oregon and have had a doubtful Californian reference, 

 which may justify noting the insert in this connection. 



Acronycta marmorata Sni. 

 Similar in type of maculation to liturata; but decidedly smaller, the pale 

 shadings nearly white, so that the insect seems marbled. The mottling is less
