occurring in that country may ultimately be found to be 

 identical with known European forms; but without some 

 knowledge of the larval cases it will be difficult to esta- 

 blish their identity, and the information at our disposal 

 is insufficient to justify an attempt at present to revise 

 the synonymy of the American representatives of the 

 genus. 



Coleophora viridiciqn-ella, n. s. (PL XVII. , figs. 2, 2rt). 



Palpi greenish bronzy, with a very slight tuft at the 

 end of the second joint. Antennae annulated with 

 greenish bronze and white. Fore wings unicolorous 

 greenish bronzy, with greyish fuscous cilia. Hind wings 

 pale brownish fuscous, with pale greyish fuscous cilia. 

 Legs greyish fuscous, the tarsi paler, the joints faintly 

 spotted with whitish on their outer sides. Abdomen 

 steel-grey above and beneath, the anal tuft paler. Ex- 

 panse, 9 mm. 



Two specimens bred from short greyish fuscous cases, 

 with the mouth slightly turned downwards, anteriorly 

 cylindrical, posteriorly somewhat flattened, and having 

 a flattened ochreous keel along their under sides. Found 

 attached to stems of a grass or rush, Mendocino County, 

 California, May 29th, 1871. Also two specimens taken 

 on the wing at Crescent City, Oregon, June 19th, 1872. 



Mr. Chambers' description of C. (enusella is so in- 

 complete that I am quite unable to judge whether this 

 species is indicated. The only reference I can find to 

 C. (Bimsella is in Can. Ent., vi., 128 : " Greenish bronzy ; 

 posterior wings pale fuscous. Al. ex. 5 lines." He 

 places it in his section of the genus having the " antennae 

 and palpi both simple." 



The very small tuft of hair-like scales at the apex of 

 the second joint of the palpi in my species might easily 

 be overlooked. 



Coleophora corncUa, n. s. (PI. XVII. , figs. 1, la). 



Palpi whitish, outwardly tinged with ochreous, the 

 second joint distinctly tufted. Antennae with the basal 

 joint enlarged and slightly tufted, annulated beyond it 

 with white and pale ochreous. Head whitish ochreous. 

 Thorax and fore wings unicolorous dull ochreous, the
