1842 BUTTERFLIES BEYOND NEAV ENGLAND. 



Legs very slender and delicate. Fore femora (males only examined) nearly a fourth 

 longer than the hind femora, a little longer than the fore tibiae ; the latter flvc-sevenths 

 the length of the fore tarsi, or of the hind tibiae; first joint of fore tarsi as long as 

 the next three together, the fifth as long as the third. Hind tiljiae fully as long as the 

 first two tarsal joints, the basal joint barely exceeding the next two together, all the 

 tarsi covered with slender spines. Claws exceedingly delicate, elongated, deeply bifid, 

 gently arcuate. Paronychia simple, formed of a single, slight, slender, triangular lobe 

 not a third as long as the claw and appressed to it. 



It is doubtful if this neat little genus of American Rhodoeeridi, recognized 

 more than fifty years ago, contains more than a single species or two. 

 Yet it is found near the back bone of the continent from Missouri to Vene- 

 zuela and is also found in at least the larger West India islands, though 

 not known even in southernmost Florida. It is the smallest of Rhodo- 

 eeridi. 



Nothing is publicly know-n of the early stages, but Mr. Edwards has 

 reared it (Can. ent., xx : 157).

Imago. Head covered with mingled yellow and black hairs and yellow scales. 

 Palpi white excepting the apical half which is made up of mingled black and greenish 

 yellow hairs and scales, with some intermingled white scales. Antennae testaceous, 

 marked along the inner and especially on the under side, as well as at the apices of 

 the joints interiorly, with silvery white; the club luteo-testaceous on the naked por- 

 tion, blackish brown on the scaled, excepting where it is overlaid with white, as on 

 nearly the whole of the under surface. Thorax covered with yellow and blackish 

 brown hairs above, beneath with pale yellowish white hairs and yellowish scales ; legs 

 luteous, overlaid heavily on the femora and tibiae, very sparsely on the tarsi, with 

 white scales ; spines and claws luteous. 



Wings above pale canary yellow with dark browm markings. On the fore xminjs the 

 brown markings consist of a large apical spot which is bounded by a very oblique 

 line which runs from a little beyond the middle of the costal border to the middle or 

 scarcely below the middle of the outer border, there merging into the upper of the 

 triangular spots which mark the tip of the lower median nervules ; it is marked by a 

 slight jog as it crosses the main subcostal nervure; in addition there is a small black 

 spot iu the middle of the outer half of the upper median interspace, and on the inner 

 margin of the wing is a broad brown or blackish brown belt leaving only a yellow line 

 between it and the margin, extending from the base almost to the outer extremity of the 

 wing, and enlarged apically by merging in a large brown spot, occupying the middle half 

 of the lower median interspace. Hind xHnys not uuf requently tinged with orange in the 

 female and there more heavily marked than in the male ; but iu both there is a brown 

 belt following the whole extent of the costo-subcostal interspace excepting its ex- 

 treme apical portion where it abruptly terminates ; and excepting, in the male, a basal 

 yellow or orange elongated spot; the extremities of all the nervnres in the upper half 

 of the wing are also marked in brown, in the female occasionally connected along the 

 margin with a faint indication of a transverse stripe in the middle of the outer half
