North American Coleophora. 433 



extreme costal margin slightly tinged with fuscous at the 

 base. Cilia ochreous. Hind wings greyish fuscous, with 

 ochreous cilia. Expanse, 15 mm. 



Bred from larvae feeding in a curiously-shaped case on 

 leaves of Cornus puhescens, Nutt., at Burney Creek ; 

 emerged in August at Mount Shasta, California. August, 

 1871. 



The case of this species is formed of a piece of the 

 leaf of the food-plant, anteriorly blackish, posteriorly 

 shading to brown ; the mouth is slightly turned over, 

 and above it the case is gradually flattened laterally, 

 bulging considerably beneath about the middle, attenu- 

 ated beyond the middle, and from thence dilated and 

 slightly bent downwards to a square end. 



Although in size considerably larger, this species is 

 not impossibly Coleophora ochrella, Cham. ; if it is so I 

 owe Mr. Chambers an apology for redescribing it ; but 

 the name ochrella is preoccupied, having been frequently 

 used in published lists for C. ochrea, Haworth, a name 

 in itself so near to " ochrella "as to cause some appre- 

 hension of confusion if both were permitted to remain 

 as applied to two distinct species. 



I have two much smaller specimens also from Cali- 

 fornia, which I regard as the true C. ochrella, Cham. ; 

 these show no signs of a tuft at the base of the antennae. 



Coleophora glaucella, n. s. (PI. XVII., figs. 3, Sa). 



Palpi whitish, mixed with brownish ochreous, with a 

 slight tuft on the second joint. Antennae with the basal 

 joint whitish above, having a short brownish ochreous 

 tuft beneath, distinctly annulated with black and white 

 beyond the first three or four basal joints. Head whitish 

 at the sides, tinged with brownish ochreous above. 

 Thorax and fore wings brownish ochreous, profusely and 

 evenly irrorated with white scales ; these are sometimes 

 predominant on the outer half of the wing, but not in 

 all specimens. Cilia pale brownish ochreous. Hind 

 wings pale brownish ochreous. Cilia rather more grey- 

 ish. Legs and abdomen brownish ochreous, somewhat 

 sprinkled with whitish scales. Expanse, 13 mm. 



Thirty- one specimens bred from larvae feeding on 

 leaves of Arctostaphylos glauca, Lindl., collected near 

 San Francisco, May 20th, 1871 ; bred July 6th to July 

 30th.
