pale brownish fuscous, which covers more than their apical half ; 

 cilia white, with a slight brownish fuscous line towards their base 

 around the apex. Underside of fore wings brownish fuscous, with all 

 the margins white ; underside of hind wings white tinged with 

 brownish fuscous. 



Legs and abdomen yellowish white. 



Expanse 17-21 millim. 



Several specimens near San Francisco and on Mount Shasta, 

 May and August, 1871. 



EucERATiA SECURELLA, sp. nov. (Plate XXXV. fig. 14.) 

 Capite et palpis hirsutis, gi-iseo-albidis ; antennis annulatis ; alls 

 anticis a basi dilatatis (casta post medium arcuata, margine 

 apicali concavo), griseo-albidis, brunneo-fusco dilute suffusis vel 

 lituratis, st)-i(/a ultra medium plicce oblique transversa fusca, 

 striga angulata diffusa apud finem cellula postice subfusco 

 marginata, litura costali post medium subconspicua, ciliis brun- 

 neo-fusco et albido alternantibus ; alis jiosticis saturate albido- 

 griseis. 

 Head and palpi very roughly clothed, greyish white above, brown- 

 ish beneath ; antennae annulated ; thorax greyish white. 



Fore wings greyish white, shaded and sometimes blotched with 

 greyish and brownish fuscous, narrow at the base, expanding out- 

 wardly, rather hatchet-shaped, having the costa somewhat arched 

 beyond the middle, the apical margin slightly concave. The species 

 is somewhat variable. In some specimens the most conspicuous 

 markings are an oblique detached transverse fuscous streak crossing 

 beyond the middle of the fold (in one example this streak is divided 

 into two spots), a pale whitish angulated streak at the posterior 

 angle of the cell, deflected and diffused outwardly towards the anal 

 angle, and a brownish fuscous, more or less conspicuous blotch 

 shghtly beyond the middle of the costa; in others this blotch is 

 extended and reduplicated towards the apical portion of the wing, 

 giving it an obliquely bifasciated appearance. The cilia are chequered 

 with alternate white and brownish or greyish fuscous spots, extend- 

 ing round the apex. Underside unicolorous greyish fuscous, with 

 chequered cilia. 



Hind wings pale whitish grey, the extreme margin faintly shaded ; 

 underside pale whitish grey. 

 Expanse 25 milhm. 



Seventeen specimens, taken in Sonoma county, California, late in 

 May 1871. 



It is larger than the preceding species, and has the apical margin 

 slightly more concave ; but in the antennae and palpi, as well as in 

 their general structure, they are very similar. 



Genus Depressaria (Haw.). 

 Mr. Chambers, in his List of described Tineina of the United States 

 and Canada, in the Bulletin U.S. Geol. and Geogr. Surv. (vol. ix. 1878), 

 enumerates twenty-seven species originally supposed to belong to this
