GRAPTA IV. 



on costal margin and along the whole hind margin, except just over the tail, where 

 the tint is lilaceous; the rest of the limb suffused with jDurjjle; commencing at the 

 upper sub-costal nervule a deej) ferruginous patch extends to median and is con- 

 tinued in a broad, curved, posteriorly attenuated strijse to anal angle; crossing 

 both wings is a row of black points, on secondaries lying within the ferruginous 

 stripe, each having a faint olivaceous halo ; along the incision of primaries a series 

 of metallic blue or green streaks or narrow lunules; on secondaries these are large 

 and distinctly lunular; discal mark on secondaries an interruj)ted C, usually 

 silvered, but at times aureous; costal edge of primaries crossed to sub-costal 

 nervure by ferruginous streaks and patches, between which the ground color is 

 buff. 



Body above fulvous, covered on thorax with green hairs; beneath grey-ferru- 

 ginous; legs buff; palpi buff, on ujiper side fulvous; antennae fuscous above, 

 annulated below with buff; club fulvous tij^ped with buff. 



Female. — Exjiands 3 inches. 



Upper side similar to male; fringes similar. 



Under side bi'own suffused with blue-grey; the hind margin of primaries 

 olive-brown; on secondaries the sub-marginal stripe and patch but faintly indi- 

 cated; the metallic spots less distinct than in male and more or less wanting; the 

 common row of black points conspicuous. 



Egg .02 in diameter; smooth, spherical, flattened at top and slightly at base; 

 from the centj-e of the base proceed ten narrow ribs, at first scarcely raised above 

 the surface, increasing gradually in prominence as they ascend, and terminating 

 abruptly and per2-)eudicularly at the rim of the flattened toji, marked on either 

 side by transverse parallel grooves ; (see plate) . Color pale green. 



The larvse emerge from the egg in from three to four days. At first, they are 

 one-tenth inch in length, translucent, greenish, covered with hairs ; the head large, 

 bilobed, black. In a few hours they change to black. After first moult, (length 

 .3 inch) which takes place in about two days, they are black, more or less specked 

 with white, and begin to be clothed with short spines, all black except those on 

 eighth and tenth segments, which are whitish. After another interval of two days 

 the second moult takes place (length .4 inch), and the larvae begin to assume the 

 type that they retain to maturity. The sjiines are in seven rows, one dorsal, two 

 lateral on each side and one infra-stigmatal, fleshy at base, slender and many- 

 branching at extremity; the dorsal and first lateral on third segment are black, 

 on second, fourth and eleventh, russet, the rest yellow; the second laterals black 

 throughout, the lowest row greenish; head bilobed, black, with short black spines 

 at vertices.
