204 JOHN B. SMITH. 



cell. Claviform black margined, coucolorous, extends about half-way across the 

 median space, a bright yellow bar completing the distance. Orbicular small, 

 oval, oblique, narrowly defined by black scales and a white annulus ; centre 

 ltiteous. Reuiform upright, oblong or a little lunate, narrow, black edged, white 

 ringed, centre luteous with narrow smoky lines. Secondaries whitish, the veins 

 smoky, a smoky extramedian line, beyond which the wing is more or less smoky, 

 a smoky discal lunule; fringes white. Beneath, primaries smoky gray, except at 

 the margins which are paler. Secondaries a little paler than above, but similar 

 in maculation ; fringes white. Expands 1.04-1.28 inches = 26-32 mrn. 



Hub. — Volga, South Dakota (Truman j ; Calgary, Alberta, Aug. 

 23rd (Dod). 



Sixteen males and one female, nearly all in very good condition. 

 The species belongs obviously to the quadridentuta series, but is quite 

 distinct from all the species by the dark margined secondaries, which 

 give it a marked resemblance to some species of Oncocnemis. The 

 single example from Mr. Dod, numbered 10, has been in my collec- 

 tion for a long time without a definite place; with the South Dakota 

 material at hand it finds a natural home. It is likely that Mr. 

 Truman had this form mixed with niveilinea in which the secondar- 

 ies are entirely white. The specimens sent me were included in a 

 miscellaneous lot of unspread supposed duplicates and have been 

 but recently brought to light. 



Agrotipliila molilalia Morr., Ann. Lye. Nat. Hist. N. Y., xi, 95, 1875. 



This name was referred by me as a synonym of A. staudingeri 

 Moeschl., after comparing Moeschler's typical specimen with the 

 Morrison specimen marked type in the Tepper collection. I have 

 still a photograph made from Moeschler's type ; but have not sue 

 ceeded in securing specimens. In looking through the collection of 

 the Museum of Comparative Zoology recently I found another speci- 

 men of Agrotis montana Morr., marked "type," which I recognized 

 as belonging to the species described as rigida by me. Comparing 

 this example with Mr. Morrison's description, it is evident that it 

 was the one actually used in delineating the characters because it 

 was the better of the two before him. To the courtesy of Prof. 

 Rufus H. Pettit of the Michigan Agricultural College, I owe a 

 sketch of the Tepper type which confirmed my previous conclusions 

 and proved that Mr. Morrison had two distinct species before him 

 when he wrote, but drew his description from one of the examples- 

 only. The Cambridge specimen is therefore the real type of Mr. 

 Morrison's name which must be restored to the list, and my rigida, 

 Trans. Am. Ent. Soc, xviii, 133, must fall in as a synonym.
