DARAPSA VERSICOLOR. 
Prof. Meyer, of Brooklyn, some years since was successful in breeding this splendid insect ; the larvse, he 
says, resembled those of D. Myron, but were larger. They feed on the Cephalanthus Oecidentalis, a plant 
which grows on margins of creeks, in swamps, &c ; has lanceolate leaves in twos and threes, and white flow- 
ers in clusters, aud is better known as the Buttonbush. It is a common weed, occurring in various parts of 
Long Island and New Jersey, and I have little doubt that careful search by collectors who have the plant 
within reach, would be rewarded by the finding of some of the larvse. Doubtless owing to the plants growing 
in and near water, very many of these larvse are drowned, which may in some measure account for the amazing 
rarity of this insect, which without exception is the most lovely of all our N. Am. species, and second only to 
the peerless Ghcerooampa Nerii, among those of other countries.

(PLATE XIII, FIG. 10.) 
“Head and thorax dull brown, (if not faded,) with a broad whitish stripe on the sides, extended to the lower edge of tegulse. 
Abdomen brownish testaceous, with faint dark-brown dorsal marks in atoms. Anterior wings rather pale brownish, punctated with 
dark atoms and with obscure dark brown lines extending from the base to the tip; discal spot dark brown and small. Posterior wings 
uniform blackish brown. Under surface of the wings brownish, somewhat tinged with rufous, and with two rows of brown spots in mid- 
dle of the posterior. California.” 
Dr. Clemens’ description above quoted agrees exactly with the example I have figured, which passed 
into my keeping along with the Lepidopterous collection of the Rev. Dr. John G. Morris some years since. 
It had no name attached, but merely the locality, “S. California ;” its former possessor could give me no fur- 
ther particulars concerning it, but I have no doubt it is the species described as Procne , though this name 
may perhaps eventually prove a synonym of some species common to Mexico and Tropical America.

(PLATE XIII, FIG. 11 9.) 
Male. Expands 2|- inches. 
Head and thorax very dark brown above, whitish-grey on sides ; abdomen light brown above, with a 
black dorsal line ; on each side a row of black spots ; beneath grey. 
Superior wings narrow and prolonged, less in length from base to inner angle than from the latter to 
apex ; exterior margin almost straight. Upper surface light brownish, shaded with darker brown at costa 
and inner margin ; a rather broad dark brown marginal band; a very small white discal spot; a narrow 
black apical line, and a few abbreviated, almost obsolete, black lines in the cells. Fringe brownish. 
Posterior wings ochrey, with broad, black marginal band, and very faint evidences of a mesial band ; 
fringe white. 
Under surface ochrey, with a rather broad brown marginal band on all wings. 
Female. Expands 3f inches. 
Head and body as in male. 
Primaries much broader and not so much prolonged, being less from apex to inner angle than from latter 
to base. Upper surface clouded with light grey ; black marginal band broadest at inner angle, and diminishes 
to a point before reaching the apex ; black apical and other streaks better defined than in the male ; exceed- 
ingly small white discal spot. Fringe dark brown and white, former colour predominating. 
Secondaries as in male. 
Under surface, primaries greyish, with a slight yellow tinge ; marginal band not well defined, whitish 
and brown, former colour gaining at and towards apex, the latter at inner angle. Fringes brown and white.
