composite flowers and on the biittonbush. Its flight is very rapid 

 and irregular, and it always keeps close to the grass tops or the sand. 

 -But when resting or when feeding it is not at all shy, so that it is 

 quite easy to catch. 



This dull-colored species is easily distinguished from all the other 

 species in our fauna by the underside of the hind wings, which are 

 rather light olive-gra}^ with conspicuous long whitish streaks. 



ATRYTONOPSIS LOAMMI (Whitney) 



Plate 55, Figures 9, 10 



This species is to be sought for as a casual visitor to the District. 

 It is easily distinguished from all the other local skippers by the 

 curious white markings on the otherwise uniform brown undersurface. 



POSTSCRIPT 



The description of Poanes massasoH hughi (p. 225) appeared in 

 the Annals of the Carnegie Museum, Pittsburgh, Pa., while this 

 memoir was in press. In a note appended to the description Dr. 

 W. J. Holland said : 



An examination of the collections of W. H. Edwards in my possession reveals 

 in the series of P. massasoit determined by Edwards, several specimens of the 

 form P. massasoit hughi Clark, from Nebraska. In the Ehrmann collection 

 bequeathed to the Carnegie Museum are three specimens of the newly named 

 subspecies from South Dakota. It is thus shown that the var. luKjhl Clark has 

 a wide distribution.
