528 THE BUTTERFLIES OF NEW ENGLAND. 



SPEYERIA SCUDDEK. 



Speveria Scudd., Syst. rev. Am. butt., 23 Argynuis pars Aiiet. 

 ({^72). " Type.—Papilio idalia Drnry. 



A butterfly, with gorgeous wings, 

 To you tall flag one moment clings. 

 Then with a sidewise wavering flight. 

 Rises and flutters out of sight. 



IvENYON. — An Incomplete Angler. 



Imago (53 : 7). Head rather large, profusely covered with moderately long hairs, 

 longest about the base of the antennae. Front pretty full, most so a little below the 

 middle, slightly and broadly depressed above, broader than high, but not nearly so 

 broad as the eye ; upper border broadly angular, the apex docked and depressed be- 

 tween the antennae, its sides scarcely curved ; lower border rather broadly rounded, 

 scarcely docked. Vertex pretty large and quite tumid, but scarcely rising above the 

 upper level of the eyes, twice as broad as long, the hinder border very broadly rounded 

 and in the middle appressed, the front rapidly sloping, the border extended forward 

 with a broad angulation, the apex docked. Eyes very large, full, naked. Antennae 

 inserted a little in advance of the middle of the summit, in deep pits, with a very 

 broad and pretty deep, transverse channel between them, separated by a space fully 

 equal to the diameter of the apex of the second antennal joint ; a little longer than the 

 abdomen, composed of flfty-two joints, the last thirteen of which form a slightly de- 

 pressed cylindrical club, flattened beneath, suboval in shape, three times as broad as 

 the stalk, two and a half or three times as long as broad, the extremity rather broadly 

 and regularly rounded, four or Ave joints entering into the diminution of size, the 

 slightly produced apex of the minute, conical, apical joint breaking a little the regu- 

 larity of the curve, furnished on the upper portion of the inner side with a single 

 slight carina extending a long Avay upon the stalk. Palpi not very large nor stout, 

 scarcely half so long again as the eye, curving slightly forward, the terminal joint 

 about one-sixth the length of the penultimate, the basal two joints furnished on either 

 side beneath with pretty long, coarse, projecting hairs, and the middle joint above 

 with shorter, scale-like hairs, which grow longer in advance of the eyes, curving 

 upward to partially encircle them, and beyond becoming thinner and projecting upward 

 and forward; only the terminal joint thickly clothed with scales, rather recumbent. 



Prothoracic lobes moderately large, not very tumid, a little longer interiorly than 

 exteriorly, in front slightly appressed, the upper surface nearly straight, both ends 

 well rounded, scarcely four times as broad as long, and somewhat higher than long. 

 Patagia very long and slender, slightly tumid, more than three times longer than the 

 extreme breadth, the base moderately broad and nearly square, the posterior lobe 

 tapering rapidly next the base, beyond nearly equal, and bent downward considerably, 

 the tip well rounded, the upper border slightly curved, scarcely sinuate, the under 

 border angulated. 



Fore wings (39 : 2) seven-eighths as long again as broad, the costal border rather 

 strongly convex, the middle half less so, the apical angle well rounded; outer margin 

 nearly straight, rounded oft" toward the angles; inner border scarcely convex in the 

 $ , scarcely concave in the ? , at an angle of about 115° to the outer border. First 

 superior subcostal nervule arising beyond the middle of the outer half of the upper 

 margin of the cell; second at the end of the cell, or a little Avithin the extreme limit 

 of its upper border, which is here pushed outward a little ; the third at about two- 

 thirds the distance from the apex of the cell to the outer border : the fourth at but a 

 short distance beyond it, about half way between the apex of the cell and the outer 

 border ; second inferior subcostal nervule arising two-flf ths way down the cell ; the 

 latter slightly more than two-flfths the length of the wing, and three times as long as 

 broad. Last median nervule connected with the vein closing the cell, nearly half as 

 far beyond its base as that is from the base of the tirst nervule.
