2 . Primaries : costa moderately arched ; external 

 margin slightly concave ; interior margin nearly straight. 

 Upper surface of wing obscure fuscus brown ; fringe 

 lunules ochreous-whitish, and very slightly expressed; 

 all the marks and spots greyish-white, dusted with dark 

 grey atoms ; within the discoidal cell a large oblique, 

 irregular, tetragonal patch more or less excised on its 

 outer and inner edges ; 8 discal longitudinal white marks 

 between the veins — the first, within the 3rd and 4th 

 subcostal branches, short ; the second, between the 4th 

 and 5th subcostal branches, short ; the third, between the 

 5th subcostal and 1st discoidal branches, twice as long: 

 all of them hastate ; the fourth very small, cuneiform, 

 and midway between the cell and hind margin ; separated 

 from this, and towards the hind margin is a larger sub- 

 cuneate spot : between the 5th subcostal and 1st discoidal 

 nervules a minute nearly obsolete white spot, almost close 

 to the median nervure, and a submarginal suborbicular 

 small spot : between the 1st and 2nd discoidal branches 

 a long tetragonal mark, its outer end more or less deeply 

 excavated to about half its length, with a suborbicular 

 white submarginal spot : between the 2nd and 3rd median 

 branches a longitudinal nearly equilateral mark, with 

 curved apex and deeply sinnate base, and a small sub- 

 marginal rhomboidal spot : between the 3rd median 

 nervule and the submedian pseudoneurus a somewhat 

 shorter hastate mark, and a minute submarginal white 

 dot, with an oblique, larger, twin spot outside the pseudo- 

 neurus. Under surface of Primaries with wing colour a 

 rich light fuscus brown ; the white spots the same in 

 number and position as above (slighly ochraceous grey, 

 without atoms), and nearly the same in size and shape, 

 except that between the 1st and 2nd median branches 

 there are three spots instead of two — the one nearest to 

 the cell being rather large and irregular in shape, a cunei- 

 form mark midway between it, and a small submarginal 

 rhomboidal spot, and that the mark between the 2nd and 

 3rd median branches is not excavated as above ; the 

 longitudinal hastate mark between the 5th subcostal and 

 1st discoidal nervules a brown irregular-shaped spot, 

 differing from that on the opposite wing. 



Secondaries : upperside obscure fuscus brown (posterior 

 margin moderately scalloped ; abdominal margin nearly 

 straight ; costa considerably curved, especially towards 

 the apex ; fringe lunules well defined, and fuscus-yellow) ; 

 a subcostal spot not far from the apex fuscus-yellow ; the 

 2nd subapical mark within the subcostal branch irregular 

 in form within and without, and more or less excavated, 

 of a sordid ochraceous white, with dense fuscus atoms ; 

 the remaining large area of wing outside the cell, from 

 the 2nd subcostal nervule to the submedian vein is a 

 sordid ochraceous white, with graduated fuscus atoms, 

 becoming denser towards the hind margin, till they are 



nearly confluent ; strongly sinuate or dentate below 

 between the 1st and 2nd subcostal nervules the whitish 

 area only extends to within 5 mms. of the cell, and the 

 curved outline narrows to the apex of the mark, which is 

 rounded off; the area between the 2nd and 3rd branches 

 is also separated from the median nervure by an oblique 

 area of brown 6 mms. in depth ; that between the 3rd 

 median branch and the submedian nervure begins about 

 half way from the base of the wing, and below its enclosed 

 spot is clouded with brown striae and atoms, with whitish 

 atoms a little way above and on the enclosed brown spot ; 

 this large whitish area also encloses five obtuse oblong 

 brown spots, sinuate at their base ; the marginal border 

 rather broad, and of the same fuscus brown as the other 

 parts of the wing ; the interior margin of the upper wing 

 with a rather dense fringe of fuscus hairs, and the greater 

 portion of the brown area from the base within the cell, 

 towards and in the abdominal margin, is also clothed with 

 similar and longer hairs. 



The under surface of the secondary wings with all the 

 markings corresponding with those above, with the addi- 

 tion of a congeries of yellow atoms, and a moderately 

 large cuneiform mark of the same colour within the 

 subcostal nervure, and a small congeries of whitish atoms 

 just within the lower part of the cell ; the brown of the 

 wing is a redder and richer fuscus ; the whitish areas are 

 a graduated pure reddish ochreous, and without the fuscus 

 atoms of the upper side. The pseudoneura of the Primary 

 wing moderately visible. 



Head dark fuscus brown ; eyes deep castaneous brown, 

 margined with ochreous white, as in the <? ; haustellum 

 piceous black ; antennae black. 



Thorax fuscus brown, and very hairy, with a central 

 longitudinal green mark ; beneath brown, with large 

 crimson scarlet breast-spots. 



Abdomen : dorsal, greyish ochreous white, most grey 

 on the first 3 segments ; subdorsal, deep reddish ochreous, 

 with lateral black dots, and the segments well expressed 

 by black ; anal segment very brown fuscus ; and tuft light 

 brown. 



Expanse of costa g3 mms. ; width of wing 54 mms. ; 

 length of secondary wing 61, and width 44 mms. ; length 

 of antennae or abdomen 41 mms. ; number of articula- 

 tions of antennas about 58 ; length of thorax with head 22, 

 and width 10 mms. The legs of the type are in too 

 imperfect a condition to be measured.

Figs. 1, 2, $ and 4, 5 5 in my plate fully represent 

 Felder's types, which I have re-drawn and re-described, 

 with the earnest hope that this addition to the valuable 

 labours of the Felders may prove useful to the students 

 of this beautiful species. 



Fig. 3 3 , represents a var. in the collection of Messrs. 

 Godman and Salvin. The differences in colour and 

 general appearance from the types are not important. 

 The upper surface presented nothing worthy of particular 

 notice, but a comparison of the under surface with the 

 type will reveal some interesting variations in the marking.
