the wing, which reaches to a pale dirty-whitish dot immediately be- 

 yond and below it, situated about the end of the cell, and surrounded 

 by some brownish scales. In some specimens is a faint indication 

 of a second pale discal dot preceding it ; and in others the two fuscous 

 dots are almost obsolete. 



Hind wings very pale greyish ochreous ; cilia of the same colour 

 as the wings. 



Expanse 21 millim. 



The species occurred at Newville, Tehama county, California, 

 July 5, 1871, and in the neighbourhood of Fort Klamath, in Oregon, 

 at the end of September, also at Old Fort Watson, in Northern Ore- 

 gon, in April of the following year, but was not abundant. 



It approaches D. ocellana (Fab.) and B. yeatiana (Fab.), but 

 differs from the latter in colour, and in having the fore wings' wider 

 and less rounded at the apex. 



Depressaria arnicella, sp. nov. (Plate XXXVI. fig. 3.) 



Capife suhochraceo; palpis subochraceis, articulo apicali annulato; 

 antennis fuscescentibus ; alls anticis saturate ochreis, fusco 

 dilute sublituratis, punctis tribus discalibus et nebula subcon- 

 spicua fuscescentibus, casta et margine apicali fusco punctatis, 

 ciliis rufescentibus ; alis posticis griseo-sericeis, ciliis rufescen- 

 tibvs. 

 Head and palpi greyish ochreous, the apical joint of the palpi 

 annulated with fuscous ; antennae greyish fuscous. 



Fore wings pale ochreous, more or less suffused and blotched with 

 greyish fuscous ; three rather fuscous discal dots, two about the 

 basal third of the wing, of which the upper one is nearer to the base 

 than the lower, and one towards the end of the cell ; between them 

 lies a slight greyish fuscous cloud, sometimes reaching to the costa ; 

 the pale basal patch is not very clearly defined, but extends above 

 the cell along the basal third of the costa ; the costal and apical 

 margins diffusely dotted with greyish fuscous. Cilia rosy reddish. 

 Hind wings shining grey, with rosy reddish cilia. 

 Expanse 22 millim. 



Five specimens, bred from larvae feeding on Arnica angustifolia 

 (Vahl), on Mount Shasta, Cahfornia, August 1871. Allied to 

 Depressaria adspersella (Kollar), but without the distinct black 

 costal dots of that species.
