types has proved to both Dr. Dyar and ourselves that the species is 

 not synonymous with lavinia Schaus as claimed by Dr. Dyar (Ins. Ins. 

 Menst. V, 79). 



Hydropionea eumoros Dyar. 



This species is the same as oblcclalis Hist, at present listed under 

 Loxostege but properly referable to the same genus as fenestralis B. & 

 McD. Dyar's name becomes a synonym. 



CRAMBINAE 



Crambus oslarellus Haim. 



It was an error on our part to cite this species (Contr. Ill, (3) 

 191) as a synonym of carpenterellus Pack. It is a good species and 

 may be distinguished from carpenterellus by the less angled nature of 

 the subterminal white line which is gently rounded opposite the cell 

 and not sharply angled as in carpenterellus ; the white costal spot pre- 

 ceding this line is larger in carpenterellus and the tooth on inner side 

 of the white basal streak is more prolonged along the vein ; the outer 

 margin is also slightly more bulging; our figure (1. c. PI. XIV, Fig. 18) 

 represents oslarellus. 



Crambus bartellus sp. nov. (PI. XXIV, Fig. 3). 



Palpi and head white, the former brown laterally; primaries white, 

 shaded with brown; the basal half of wing entirely white with some slight 

 pale brown shading in the cell at base and along vein 1 ; a broad dentate 

 brown median band with prominent outward angles in the cell and below 

 median vein shaded with blackish; outer half of s. t. area brown-shaded; s. t. 

 line fine, brown, prominently bent outward opposite cell and with slight inward 

 angle above inner margin, partially separated from subterminal brown shading 

 by a white line, especially distinct at costa ; terminal area white, with outward 

 brown shading cut by the pale veins; fringes brown, slightly cut by white and 

 with distinct white basal line; secondaries pale smoky with indistinct dark s. t. 

 line. Beneath pale smoky, veins of primaries marked with white terminally, 

 secondaries as above. Expanse 22 mm. 



Habitat: Tuolumne Meadows, Calif. (Aug.). 3 $. Tv-pes, Coll. 

 Barnes. 



Closely related to oregonicus Grt. of which it may be merely a 

 race with the white areas greatly extended; its white color with con- 

 trasting brown bands should make it easily recognizable.
