1908. Sm., Can. Ent., XL, 228, Rhynclutijrotin. 



RHYNCHAGROTIS DUANCA, n. sp. 



Blackish-smoky; head and collar faded, more yellowi.sli, secondaries 

 with a brownish shade. Primaries with all tlie transverse niacuhition lost 

 or barely traceable; ordinary spots small, traceable by sli^-litly paler 

 annuli. 



Expands— 1.22-1.36 inches = 30-34 "'■". 



Habitat — Stockton, Utah, IX, X; California. 



Two $ 's and 3 5 's in rather unsatisfactory condition, but obviously 

 different from anything else in this series. It is narrower winged than 

 nefascia and with the maculation almost all lost. I have a pair of speci- 

 mens from Montana, which are practically the same, but there is enough 

 question about it to prevent my placing them in the type series. 



Ti'PE Locality: Stockton, Utah; and California. 



Num]!i:r axu Sexes of Types: '2$, 35. 



Types ix: Holotype ("Male Type"), Stockton, Utah; Allotype ("Fe 

 male Type"), Stockton, Utah; I5 Paratype ("Cotype"), Stockton, Utah;

 Barnes Collection. 



SPEci3rENS Examined: Total 33; from Provo, Stockton and Eureka, 

 Utah; Esmeralda Co., and Reno, Nev.; Truckee ancl Shasta Retreat, Calif.; 

 Prescott, Ariz.; 1 Paratype and 16 Topotypes from Stockton, Utah. 



Genetalic Slides: 3, from Stockton, Utah. 



Dr. Sniith's description may be modified as follows: Ground 

 color blackish-smoky, often with a reddish tinge. Head and collar 

 any shade of yellow to orange. Collar with or without a transverse 

 dark band; or exceptionally tlie collar may match the ground color 

 of the primaries. Transverse maculation of the primaries traceable 

 but faint. Ordinary sjoots small and traceable bj" whitish annuli. 

 Expanse 1.0-1.36 inches. With a distinct smooth scaled, clean-cut 

 appearance, and a beautiful silky luster. Slightly narrower winged 

 than nefascia.. Antennae finel}' ciliated with longer setae to the 

 joints. 



LAM PR A NEFASCIA, Sm. 



1908. Sm., Can. Ent., XL, 227, Rhynchagrotis. 



RHYNCHAGROTIS NEGASCIA, n. sp. 



Similar to placida in size and general appearance, but with less trigo- 

 nate and more stumpy primaries. The absence of a distinct median shade 

 has been already noted (*). ancl, in addition, the ordinary spots are smaller, 

 the reniform especially tending to become narrow, oblong, with^ the angle 

 rounded rather tiian kidney-shaped. The secondaries in botii sexes are 

 very evenly blackish, whereas in flacida tiiey are decidedly paler at the 

 base, and in no case evenly blackish. The primaries have tlie appearance 

 of being more densely scaled, and while finely powdered, appear more even 

 in general tint. 



There is a large series of both sexes before me from Ft. Wingate, New 

 Mexico, and another, collected by Mr. Buchholz, from Yavapai Co., Arizona. 

 Altogether of spread material there are 3-5 $ 's and 47 $ 's showing a re- 

 markable uniformity in general characteristics, while j'et the terminal space 

 is contrastingly blue in some examples, nearly concolorous in others, and the 

 predominating shade may range from creamy-luteous to brick-red in one 

 direction, and smoky or gray-brown in tlie other, the ordinary spots are 

 usually a little darker and outlined liy rather broad annuli of the ground 

 color.
