The tyj)es of Mr. Grote's species are in the British Museum, and so 

 is also elimata Gn. With them are specimens labeled dilucida by Mr. 

 Grote, and these are exactly like Guen^e's species. Mr. Morrison 

 labeled a number of specimens as " type" and I have seen several of them 

 in collections. They include specimens like Guen(5e's type and also 

 like Mr. Grote's /a w?m?/s. Mr. Morrison pointed out some of the char- 

 acters differentiating his species from elimata; but these are not essen- 

 tial. As the forms stand in the Britisli Museum, they look like good 

 species; elimata ratlier more gray with the markings well defined and 

 the apices of primaries distinct; badicollis much like it in wing form 

 and markings, but still paler and with a contrasting pale coWsir; janualis 

 rounder winged, ai^ices more obtuse, markings almost obsolete. In the 

 large series in the U. S. National Museum the differences seem to vanish; 

 but none of the specimens are like typical badicollis, which I never 

 saw previously. Mr. Thaxter also has types of Mr. Grote's species. 

 To differentiate the various forms I have given varietal rank to Mr. 

 Grote's names. Dr. Lintner also has a "type" of badicollis. 



S. opacifrons Grt.* 



1878. Grt., Bull. Geol. Surv., iv, 170, Agrotis. 



1890. Smith, Bull. U. S. Nat. Mus., No. 38, 97, Noctua. 



Habitat. — New York and northward. 



The male type in the British Museum has pectinated antennae and 

 the wing form of elimata. The specimens before me when writing the 

 monograph were females only, and I failed to recognize the true rela- 

 tionship of the species.
