scales, the thorax not crested. Palpi blackish above, beneath 

 white. Antennae simple, filiform, grey, beneath reddish. 

 Abdomen greyish white, with scattered black scales. Fore-wings 

 very elongate-triangular, hind-margin somewhat obliquely rounded, 

 slightly waved ; white, with scattered black and fuscous scales, 

 more numerous towards costa. A small reddish-ochreous elongate 

 discal spot. A short sub-basal interrupted line from costa to 

 just below median nervure, usually only indicated by a blackish 

 spot at base of costa, and another immediately below median 

 nervure. Two reddish-ochreous transverse lines, first from £ of 

 costa to | of inner margin, twice outwardly curved, almost 

 dentate ; second from rather more than § of costa to the same of 

 inner margin, inwardly curved below middle, sharply dentate on 

 upper §-, Beyond this are two reddish-ochreous suffused patches, 

 one about middle, and the other towards anal angle, usually 

 indicated by clusters of three or four spots ; a terminal series of 

 blackish semilunate marks ; cilia white, sometimes tipped with 

 reddish-ochreous between veins. 



Hind-wings with hind-margin unevenly rounded, rather sinuate 

 about middle, dark grey, with a very broad blackish hind-mar- 

 ginal band and small discal spot ; cilia dark grey, tipped with 

 white. 



Female. — 63 mm. Similar to above, with the following excep- 

 tions : — A broad median transverse reddish-ochreous suffusion 

 occupying the space between the first and second lines, but not 

 reaching costa, and extending along inner margin towards base. 

 Abdomen with dorsal surface of the second to fourth segments 

 dark grey. 



Var. A. — Male. — 52 mm. Resembling the female, though 

 darker generally, the median band being fuscous, dark grey on

 except basal segment and anal tuft, which are whitish, beneath 

 white. 



Larva. — Bright green, darker above, and ornamented with fine 

 white and yellow markings, those towards the dorsal surface 

 forming interrupted white longitudinal wavy lines, and on the 

 sides small scattered yellowish spots. A lateral series of larger 

 yellowish elongate spots on each of the fifth to the last segments ; 

 ventral surface very pale greenish white. Each segment is fur- 

 nished with several small conical spiny projections, with two 

 longer black ones on the fifth, rather more in length than the 

 diameter of the body, and ornamented with minute white dots, 

 and a shorter conical one, bifid for about half its length, on the 

 eleventh segment. A dorsal series of broad black patches orna-
