_Under Side._ Breast, sides, abdomen, legs, and wings very dark brown. A dark narrow line begins at the anterior edge of the superior wings, about a quarter of an inch from the tips, and crossing them and the posterior ones ends at the abdominal edges, just below the body; dividing each wing into two compartments, that above the line being a degree darker than that below it; in the centre of each of these divisions is placed a faint black spot, and along the external edges are several of a smaller size, and equally faint. Margins of the wings entire. {42}PLATE XXIII. [Illustration] URANIA RHIPHEUS. Plate XXIII. fig. 1, 2. ORDER: Lepidoptera. SECTION: Crepuscularia? FAMILY: Uraniidæ. GENUS. URANIA, _Fabr._ (Syst.

The ground of the anterior wings is a lovely deep green, marked or striped all over with irregular streaks of a deep black, almost all of which run in a direction from the anterior to the posterior edges. Posterior wings, next the body, black; but towards the anterior edges are of a fine light blue green, clouded with black. The other parts, next the abdominal and external edges, are of a curious, deep, blood-red, shining with gold, and spotted with black. _Under Side._ Palpi grey. Breast and abdomen ash-coloured. Wings light sea-green, clouded or marked as on the upper side with black. Posterior wings, next the body, of a most brilliant golden green, with small spots of black, which green softens into a fine purple, from that into a crimson, then into a blood-red, and lastly to an orange; which colours occupy the greater part of these wings: that part which lies next the upper corners being of a fine blue green, clouded with black; all the colours on this side have a rich glow of gold, and appear changeable, according to the position in which the light strikes on them; from the abdominal corner runs a narrow black border along the external edge, the width of three membranes, stopping at the angle, and communicating with a large black spot situated near the abdominal edge. "The whole exhibiting the most beautiful colours I ever saw united in one insect."
