398 THE BUTTERFLIES OF NEW EXGLAND. 



base and on the club, dark, dull castaueous ; three apical joints of club, equally above 

 and below, luteous. Tongue pale luteous, the apical half darli luteous ; papillae indian- 

 club shaped, about five times as long as broad, appressed, truncate and cup-shaped at 

 tip, the central filament slender, blunth' pointed, half as long as the width of the 

 papilla, the edge of the cup with four or five thorns half as long as the filament ; not 

 crowded, with room for twice the number in the space occupied, which is about 

 the apical seventh of the tongue. 



Thorax covered above with fulvo-maroon hairs and below with coarser white, or 

 yellow tipped black hairs ; fore legs black, covered with similar hairs ; femora of 

 other legs dark fuliginous brown, enlivened above and at tip with some pale yellowish 

 brown scales; tibiae and tarsi wholly pale yellowish brown, the tarsi growing a little 

 dusky toward the tip; spurs red, tipped with black; spines black, claws dark red, 

 paronychia blackish. 



Wings above dark, rich mart)on, ornamented with black, blue and yellow; on the /ore 

 wings the maroon verges toward black or blackish brown along the costal border, above 

 the subcostal nervure and its first inferior branch ; the costal edge and the whole margin 

 to the costal nervure on the basal half of the wing largely flecked with short, slender, 

 broken, transverse lines of straw yelloAv; at the tip of the first superior branch of the 

 subcostal nervure a small, ti-ansverse, yellowish spot depends from the costal margin 

 just crossing the black area, and dii'ected slightly outwards ; further on, midway 

 between this and the apex, is a similar spot, ecpially narrow and having a similar 

 direction, which reaches the first inferior subcostal nervure, sometimes attenuated 

 below; directly beyond this spot commences a transverse, equal, black band, having 

 strongly crenulate borders, slightly narrower than the marginal band and subparallel 

 to the outer margin; it encloses, in each of the interspaces^ which open on the outer 

 margin, a not very large, longitudinal, suboval or subtriangular, dark, caerulean blue 

 spot, broadest outwardly; outer margin for fully the width of an interspace pale 

 straw yelloAV (in hibernated specimens whitish), largely fiecked, especially on the 

 upper half of the wing, particularly in the neighborhood of the nervules, and most of 

 all at the dentation of the Aving formed by the prolongation of the first inferior sub- 

 costal nervule, witli exceedingly short, transverse, irregular threads of blackish 

 brown, frequently mingled on the dentation with pale bluish scales. Fringe at the 

 nervure tips blackish, marked with dirty brown, on the interspaces whitish fiecked 

 with dirty brown. Hind loings with the maroon base less deep than on the fore wings, 

 Ijeing more or less specked with dark brown ; the black submarginal band encloses 

 blue spots similar to, but usually larger than, those on the fore wings, and is itself 

 broader than on the fore wings and broader than the marginal band, tapering toward 

 either end, its own borders less crenulate than on the fore wings, sometimes nearly 

 regular ; outer margin similar to that of the fore wings in color and width, but narrow- 

 ing toward the anal angle, flecked, especially (as a general thing) in the median area, 

 with transverse, rather short, irregular threads of blackish scales, coarser and more 

 distinctly separated than on the fore wings, less profusely and generally distrii)uted, 

 but still more abundant upon the nervules than elsewhere, and nearly concealing the 

 yellow at the extremity of the upper median nervule, which forms the dentation. 

 Fringe white, occasionally flecked lightly with dusky at the nervure tips. 



Beneath, very dark plumbeo-metallic blue, profusely streaked with short, transverse, 

 straight, black lines, composed irregularly of from one to three rows of scales, and 

 enlivened very slightly with scattered dull, pale ferruginous, whitish and pale straw 

 yellow scales, collected to a certain extent in delicate clusters, and generally found in the 

 innnediate vicinity of the nervules; scattered over all the wings. l)ut more abundantly 

 on the hind pair, and nearly absent from the lower half of fore wings, are infrequent, 

 l^ng, longitudinally recumbent. l)lue l)lack, spinous hairs, tipped with yellowish brown. 

 On the fore wings the two costal spots of the upper surface ai)pear, but less distinctly, 

 and of a grayish Avhite ; the marginal band is of the same width as above, but is here pre- 

 ceded not by a black band and blue spots, Imt by a sti'ongly crenate,. slender, c<iual, iucon- 

 spicous stripe (corrospondinii- in diroctioii ti> the exterior margin of ttie black band of tlie
