This last species, 5". osseella IValsingham, is known only from the 

 two female types in Zeller's collection, now in the British Museum, 

 supposed to have come from California. By the description it cannot 

 be differentiated froin the eastern S. qiierciclla Busck, and it may ulti- 

 mately prove that this name is a synonym of osseella, but to this date 

 no specimen of querciella has been received from California; in fact, 

 tho very considerable collecting has been done of late years on the 

 west coast no species of Stenonia has been obtained west of the Rocky 

 Mountains and the family is apparently not represented there. I am 

 therefore inclined to doubt the locality given to the Zeller specimens, 

 which may prove to come from central or South America. 



All the North American species of Stenoma may readily be deter- 

 mined by their striking characters of the male genitalia shown on 

 plates XXIX and XXX. 



Stenoma lindseyi, n. sp. PI. XXIX, Fig. 2. 



Closely allied to and very similar in size and color to Stenoma schlaegeri, 

 of which it is the western representative; but the forewings are somewhat 

 longer, narrower and more pointed and the dark dorsal area, which in schlaegeri 

 is interrupted by white shortly beyond the middle of the wing, is continued to 

 tornus. Hindwings of the males dark brownish or blackish fuscous, very con- 

 siderably darker than those of schlaegeri. The genitalia of the male are nearest 

 to those of schlaegeri, asymmetrical and with uncus simple as in this species, 

 but with the left antlerlike organ hooked, not forked and with a differently 

 shaped oedeagus. 



Alar expanse : 25-28 mm. 



Habitat: Paradise and White Mts., Arizona; Fort Wingate, New Mexico. 



Type and cotypes in Collection Barnes; cotvpes in U. S. National Museum 

 (No. 22670). 



Named in honor of Dr. A. W. Lindsey, who in many ways has 

 materially assisted in the preparation of this paper and who has been 

 good enough to draw the genitalia for this family, which were found 

 to be uiisuited for photographic reproduction. 



Stenoma irene, n. sp. PI. XXVIII, Fig. 7. 9; PI. XXX, Fig. I. 



Labial palpi white, slightly shaded with dark fuscous exteriorly. Face and 

 head white. Thorax dark fuscous with a proportionately large bluish black 

 rounded posterior tuft. Forewings of the females white with the extreme base 

 of dorsal edge dark fuscous, a conspicuous deep black short transverse streak 

 on the end of the cell; a faint, ill-defined fuscous shade below this to tornus; 

 a very faint narrow transverse, outwardly curved, fuscous line across apical
