male. The general type of maculation is the same; but in the new 

 species it is darker, more clearly written, while a white powdering on 

 the costal cell and along the median vein gives a somewhat character- 

 istic appearance. The cell around the ordinary spots is evidently 

 darker and the centers of the spots themselves are dusky. This, in the 

 case of the orbicular, serves as an easy method for ready differentia- 

 tion, for in messoria this spot is never darkened; in the ]iew form it is 

 obviously dusky in every case, leaving a pale annulus inside the black 

 defining ring. The transverse line in the collar is much more feebly 

 marked than in messoria and the secondaries have the dusky shading 

 blackish, rather than yellow tinged. 



Altogether, while the individual differences are slight, the sum of 

 the characters and their uniformity in the series before me indicates a 

 good species. 



Expanse, 35 to 42 mm.= 1.40 to 1.68 inches. 



Rabitat. — Pnllman, Washington, in August (Piper); Santa Oruz 

 Mountains, California (Ehrhorn). 



Five males and six females.

27. CARNEADES TERRENUS, new species. 



Ground color a dull, luteous, gray brown, irrorate with coarse black 

 scales. Collar with a blackish transverse line. Primaries with all (he 

 markings present and of the messoria type. Transverse anterior line 

 more nearly upright and the outcurves less marked. Transverse pos- 

 terior line practically as in messoria. Subterminal line vague, broken, 

 preceded by a more or less evident broken, blackish shade, which is 

 never contrasting. Terminal space not darker than the ground. 

 Median shade very vague and diffuse, sometimes scarcely traceable. 

 Claviform never complete, usually marked by a few scales only, often 

 obsolete. The ordinary spots much as in messoria^ save that they are 

 less relieved and the reniform is smaller, without central powderings. 

 The cell between the ordinary spots is dusky; but this shade rarely 

 extends beyond the reniform or into the median space. Secondaries 

 even, smoky fuscous in both sexes, a little darker in the female. 



Expanse, 35 to 40 mm.=: 1.40 to 1.60 inches. 



Habitat. — Pullman, Washington, June and July (C. V. Piper). 



A series of 12 males and 5 females is quite uniform in general 

 appearance, obviously distinct from messoria by the darker, coarsely 

 powdered primaries, on which the usual maculation is obscure, and by 

 the uniformly dusky secondaries. The new species also averages 

 larger than its ally, the majority of the examples attaining 38 mm.

28. CARNEADES TERRITORIALIS, new species. 



Ground color a very light reddish gray, tending to mouse gray, even, 

 hardly powdery. Head and thorax immaculate, collar with a dusky
