Agrotis aratrix Harvoy, Ijiill. B. S. N. S. H, 74, plate 3, fig. S. 



This species, originally described from Texas, is sent by Mr. Hy. Ed- 

 wards, under the number 7171, from Arizona. It belongs with the fol- 

 lowing to the sub-genus Ammoconia, characterized by a sharp mesial 

 thoracic tuft. 



Agrotis cliortalis Harvey, Bull. B. S. N. S. 3, 74, plate 3, fig. 9. 



This species, originally described from Texas, is now sent from Pres- 

 cott, Arizona, by Mr. Hy. Edwards, under the number 7172. Both these 

 and the preceding are, I believe, now recorded outside of Texas for the 

 first time. 



Oncocnemis mirificalis u. s. 



9 . With bright j^ellow secondaries and allied to 0. dayi, rather than 

 to 0. liayesi. A specimen of the latter is contained in Mr. Hy. Edwards's 

 collection from Colorado. Fore tibiae with a claw; the remaining tibice 

 unarmed. Smaller than 0. dayi. Fore wings dull brownish, with the 

 stigmata small, distinct. Orbicular elongate, with brown center; reni- 

 form with brown central streak, moderate; claviform small, pointed, 

 with brown center; all the stigmata pale, with fine black annuli; a 

 basal fine black streak before the claviform. Lines obsolete, marked on 

 costa. Subterminal, broken into white marks, preceded partially by 

 black cuneate dashes; this line is near the margin, irregular; at the 

 middle of the wing, the longer white dashes nearly attain the margin. 

 Fringes checquered pale and dark. Hind wings bright yellow, without 

 dusky hair at base or transverse markings. A broad bright black 

 terminal band. Fringes whitish, with a blackish basal line. Beneath 

 clear bright yellow, immaculate, with a broad marginal black band on 

 both wings, reaching to the margin, as in 0. liayesi. Fringes as on 

 upper surface. Head and thorax like fore wings. JExpanse, 26 mil. 

 Hah.— Nevadsi, Coll. Mr. Hy. Edwards. 



Mamestra arietis u. s. 



(? . This species is gray, with white lines, approaching the Californian 

 insolens and the blue-gray European species, such as ccerulescens, usually 

 referred to JDianthoecia. Thorax and head whitish gray. Fore wings 

 fuscous gray, with yellow points to the dotted subterminal line. Costa 

 distinctly dotted. Median lines blackish, double, distinct, with wliite 

 included space, rather near together, lunulate. Eeniform and orbicular 

 whitish gray, distinct, and well-sized, with darker centers. A terminal 

 dotted line; fringes checquered, with a fine mesial dark line. Hind 

 wings fuscous, with traces of a median shade-hue followed by a paler 

 shading. Fringes pale, faintly lined. Beneath fuscous-gray, with com- 

 mon line and dots; line on hind wings irregular; discal mark on prima- 

 ries near the line. Abdomen fuscous gray. Expanse, 33 mil. 



Hah.— CMifornm, Mr. Hy. Edwards, 71G9. Two specimens examined. 



This species, though much paler in color and differing in the shape 

 of the t, a. line, is perhaps nearest to the Cahfornian .¥. cimeata (hote.
