dull purplish fuscous rather than yellowish brown ; the palpi also 

 are much mottled and faintly annulated with purplish fuscous. 



Other specimens, taken in Northern Oregon in 1 872, have the pale 

 head, thorax, and basal patch much obscured by the purplish fuscous 

 hue of the fore wings, and the pale discal spot obsolete ; but these 

 have probably lost some of their brilliancy during hibernation. 



In all these the two blackish spots before the middle and the 

 blackish speckling beyond it are clearly distinguishable. On the 

 whole it is doubtful whether the species should or should not be 

 regarded as distinct from its European representative. I have no 

 doubt that the eastern and western American examples are mere 

 local forms of the same insect, although the ground-colour of the 

 fore wings of the specimen from the east accords much more nearly 

 with that of the true Depressaria parilella. 



If an investigation of its habits should lead to the conclusion that 

 the American form is a distinct species, I would propose for it the 

 name Depressaria novi-mundi. 



Depressaria emeritella (Stn.). 



I bred four specimens of this rather rare European Depressaria 

 from larvae found feeding on leaves of what may have been a species 

 of Tanacetum, in May 1872, on Rouge river, in Southern Oregon. 

 I cannot find that I have preserved any specimen of the food-plant ; 

 but in my notes it is recorded as an Artemisia. 



The specimens agree to the most minute particular with Mr. 

 Stainton's description of this. species- 



Depressaria umbraticostella, sp. nov. (Plate XXXVI. 

 fig. 8.) 



Capite et palpis sordide ochraceis ; antennis fuscis ; thorace nigro- 

 fusco ; alis anticis sordide ochreis, macula basali, punctulis 

 duobus disci, punctis costalibus et marginalihiis diffusis et 

 nebula costce medics nigro-fuscis, margine apicali late sub/usco 

 adumbrato, ciliis fuscescentibus ; jwsticis griseo-sericeis. 



Head and palpi dull ochreous, the latter dusted with fuscous ; 

 antennse fuscous. Thorax blackish fuscous. 



Fore wings dull ochreous, slightly paler than the head, with a 

 short, blackish fuscous basal patch, wider pn the dorsal than on the 

 costal margin ; several minute, diffused, blackish fuscous spots along 

 the costal and apical margins ; a conspicuous outwardly diffused 

 blackish fuscous shade on the middle of the costa, preceded by two 

 minute discal dots of the same colour, of which the upper one is 

 nearer to the base than the lower, and a more or less conspicuous 

 wide subfuscous shade around the apical margin, reaching from the 

 costal patch to the middle of the dorsal margin. Cilia subfuscous. 



Hind wings rather shining greyish. 



Expanse 16-19 millim. 



Taken on Mount Shasta, California, in August 1871, and in 

 Northern Oregon in April 1872, where it was not uncommon. It
