OF WASHINGTON, VOLUME XI, 1909 91 



I have since on two occasions examined Walker's type in the 

 British Museum and found it to belong to the present genus 

 and to be identical with Dichoincris roseocostella Walsingham. 



While writing on this genus I might mention that I now 

 regard the malifoliella of Fitch as but another synonym of 

 lujnlclla Hiibner and the hitherto unidentified qiicrciclla Cham- 

 bers as a synonym of rcntrella Fitch. 



Dichomeris deflecta, new species. 



Second joint of labial palpi white, sprinkled with light ochreous 

 scales; terminal joint nearly pure white with the extreme tip black; the 

 terminal joint in the type (female) before me is rather peculiarly 

 deflected and appears as a continuation of the tuft on second joint, but 

 I judge this is merely an accidental position assumed when the insect 

 was killed. Tongue long, curled, scaled at base. Maxillary palpi dis- 

 tinct, short, simple, pointed. Antennae light fuscous. Head and thorax 

 white, sprinkled with light ochreous scales. Fore-wings elongate, 

 pointed, termen slightly sinuate below the somewhat produced apex; 

 the white ground color is heavily overlaid with light ochreous, fuscous, 

 and blackish scales, the central part of the wing only being nearly un- 

 mottled ; there is a large round, blackish, first discal spot and a small 

 black dot at the end of the cell ; the flexus is marked by a few black 

 scales and the veins are indicated by longitudinal blackish-fuscous lines, 

 which terminate in a series of apical spots along the edge of the wing. 

 Hind-wings ochreous fuscous. Legs white ; the anterior pairs strongly 

 mottled with fuscous, the posterior scarcely so. 



Alar expanse, 23 mm. 



Habitat Redington, Arizona. 



Type U. S. National Museum No. 12278. 



A large light species, not mistakable for any other described 

 American species of the genus, but reminding one in a general 

 way of the much larger Dorata lincata Walsingham. 



ETHMIIM:, new family. 



In my "Revision of the American Oecophoridse" (Proc. U.S. 

 Nat. Mns., xxxv, p. 205, 1908) was suggested the necessity of 

 recognizing Ethmia Hiibner and allies as a family distinct from 

 the Oecophoridae, with which they have hitherto been classed. 

 The family name was even proposed in the manuscript, but due 

 to my absence in England at the time, it was left out in the 

 final proof by a mistake, which is now corrected. 



The main structural character by which this family may be 

 distinguished from the Oecophoridcie is the proximity of vein 

 5 in the hind wings to vein 6 instead of to vein 4, as in Oeco- 

 phoridje, it being radial, not cubital; but the general habitus is
