114 DARAPSA VERSICOLOR. 



Prof. Meyer, of Brooklyn, some years since was successful in breeding this splendid insect; the larvee, he 

 says, resembled those of l>.J/(/;-on, but were larger. They feed on the Cephalanthus Occidentalis, a plant 

 which grows on margins of creeks, in swamps, &g ; has lanceolate leaves in twos and threes, and white flow- 

 ers in clusters, and is better known as tiie 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 larva. Doubtless owing to the plants growino- 

 in an<] near water, very many of these larv» 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 Charocampa Nerii, among those of other countries.

"Head and thorax dull brown, (if not faded,) with a broad whitish stripe on the sides, e.xtended to the lower edge of tegul». 

 Abdomen brownish testaceous, with faint dark-brown dorsal marks in atoms. Anterior wings rather pale brownish, punctated with 

 dark atoms .ami with obscure dark brown lines extending from the base to the tip ; discal spot dark brown and small.' Posterior wings 

 uniform blackisli brown. Under surface of the wings brownish, somewhat tinged with rufou.s, and with two rows of brown spots in mid- 

 dle of the posterior. California." 



Dr. Clertiens' 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 ?.) 



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 niargin almost straight. Upper surface light brownish, shaded with darker brown at eosta 

 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 baud, 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 ;3| 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 baud not well defined, whitish 

 and brown, former colour gaining at and towards apex, the latter at inner angle. Fringes brown and white.
