specimen without disturbing the synonymy. In any case vernata be- 

 comes a synonym. 



Lygris atrifasciata Hist. (PI. XIII, Fig. 17). 



This species has already been removed from the synonymy of 

 Mesoleuca immanata, where it is listed by Dyar, by Grossbeck (Tr. 

 Am. Ent. Soc. XXXIII, 338) who places it in Eustroma; the species 

 was described from a single 2 from California and if we have cor- 

 rectly identified it from our notes on the type, the $ sex is without a 

 hair pencil on the underside of fore wings. The species is very apt 

 to be confused with nubilata Pack, but the central broad black fascia 

 is more prominent and its inner margin, while irregular, does not 

 show the prominent tooth in the cell which characterizes nubilata 

 {vide Packard's figure PI. VIII, Fig. 46) ; on the hind wings the 

 median line is nearer the base of the wing and more sharply angled, 

 forming practically a right angle, and the species is much more uni- 

 colorous smoky without the sprinkling of white or yellow scales found 

 in nubilata; the abdomen is unspotted whilst in nubilata there is a 

 row of subdorsal black spots ; it would seem best placed in Lygris 

 being one of the few species of this genus without the hair pencil. 

 Judging by the description Warren has redescribed it from Colorado 

 as Epirrhoe delimitata. It is apparently wide spread as we have it 

 from California, Arizona, Utah, and Colorado (all from high alti- 

 tudes). With regard to semiatrata Hist., listed as a synonym of 

 nubilata, we would remark that the species was described from 4 

 specimens from Colorado but the type in the Hulst Collection is 

 labelled 'Washington Terr.' and is therefore spurious ; while it is 

 possible that semiatrata should rather be associated with atrifasciata 

 than with nubilata we believe that there would be no harm in leaving 

 it in its present association until the true type can be discovered. We 

 figure a $ of atrifasciata from Truckee, Calif. 



Lygris speciosa Hist. 



This appears to us to be nothing but an aberration of L. xylina 

 in which the antemedian yellowish band is broader than usual, en- 

 croaching on the space occupied by the dark median band. With 

 regard to xylina we might say that the type in the Hulst Collection is 

 a $ from New York, to which we would restrict the name, making 

 the form from the Eastern States the nimotypical one.
