Chrysophanus Hiibn., Verz. bek. schmett., 72 (1816). Type.— Pap. hippothoe Linn. 



As rising on its purple wing 

 The insect-queen of eastern spring, 

 O'er emerald meadows of Kashmeer 

 Invites the yuiiiig pursuer near. 

 And liails liini on IrcMii flower to Hower 

 A weary cliase and wasted hour, 

 Then leaves him, as it soars on high,

 With hue as bright, and wing as wMld ; 

 A chase of idle'hopes and fears. 

 Begun in folly, elo.sed in tears.

Imago (55:8). Head moderately large, densely clothed with scales and rather 

 abundantly supplied with long, curving hairs of eciual length in all parts. Front even, 

 not swollen in any part, except in the least possible degree in the middle below, 

 where it barely surpasses the front of the eyes ; half as high again as broad and of 

 the width of the eye on a front view; upper border marked by the faintest possible 

 transverse ridge, its angles rather deeply hollowed in front of the antennae; lower 

 border rather strongly, not broadly rounded. Vertex slightly elevated in the middle 

 and at either side to form low buttresses behind the antennae ; separated from the 

 occiput by a broad, rather deep, slightly curving sulcation, having a slight pit in the 

 middle, which affects the height of the occiput just behind. Eyes not very large, 

 moderately full, naked. Antennae inserted with the posterior border in the middle of 

 the summit, separated by a space equal to the width of the basal joint of the 

 antennae; nearly or quite half us long again as the abdomen, composed of thirty- 

 three joints, of which thirteen form the depressed cylindrical club, which is two and
