Oh restlessly 



Tlie gay Sweet-pea 



Nods on her.slender stem, 

 For far up iu the sunny skies 

 She sees the sailing butterflies, 



And longs to go to them. 



For wliy should they 

 Be first to say, 



"We love thee, pretty maid" — 

 "Why for their coming must she wait, 

 Nor speak of love till they dictate, 



Though Time her wing's should fade? 



She wonders why 

 She must not fly. 



Her warm heart's love to say — 

 Her pink and white and scarlet wings 

 Were surely made for better things, 



Than thus at home to stay !

Imago (9 :7, 10). Head covered with dark gray-browu hairs with a very inconspicuous 

 edging of pale scales next the eye and particularly just behind the antennae ; occasion- 

 ally a very few white hairs occur midway between tlie hinder edges of the two antennae, 

 and the anterior facing of the hairs in front of the antennae which rest upon the palpi 

 is also pale; tuft on outside tlie antennae black; palpi dark gray from a comming- 

 ling of pale brown, and dark brown hairs and scales, most of which are pale tipped; rather 

 darker above than below, the apical joint wholly dark brown; antennae dusky brown, 

 tinged with yellowish and uniform, the base of the joints of the stalk distinctly touched 

 with white beneath and especially anteriorly, where on the basal five or sis joints it 

 is confluent, forming a longitudinal stripe; above, the club is a little darker than the 

 stalk ; beneath, it is bathed in silvery gray posteriorly, naked and dark griseous anterior- 

 ly, becoming tinged with castaneous toward the tip, sometimes wholly castaneous, 

 the upper as well as under surface of the terminal joint being of this color. Tongue 

 blackish fuscous, dark castaneous at the sides, becoming luteo-castaneous apically. 



Thorax covered with nearly uniform, very dark brown hairs, below with similar ones, 

 sometimes with a purplish or grayish tinge. Legs uniform dark, slightly purplish 

 brown, paler beneath, the tarsi beneath reddish luteous ; spurs dark brown, minutely 

 reddish tipped ; spines reddish luteous ; claws dusky reddish ; pad blackish. 



Wings above soft cloudy blackish, sometimes dark grayish brown, marked incon- 

 spicously with still darker spots. Fore winys usually more grayish in the 2 th'^'^ i" tl"® 

 $ ; they are also marked with small vitreous or occasionally dull silvery white spots; 

 one of these, usually square, crosses the upper half of the cell between the bases of the 

 first and second superior subcostal nervules; the others form a series almost invariably 

 broken, four being found above in the subcostal interspaces and one or two below in 

 the median interspaces, the lower somtimes obsolete; in a single example under ex- 

 amination, these are all united by similar spots in the intervening interspaces to 

 form a perfectly uniform arcuate series ; in general the four upper spots are rather 

 smaller than the upper median one and are unequal, the upper and lower being ordi- 

 narily equal, the middle ones elongate, the upper of them extending toward the apex, 

 the lower toward the base of the wing ; but occasionally they are all elongate ; they
