placed a lengthened spot of King's yellow. The anal angle 

 King's yellow, without any black spot such as is found in 

 the other species, the base, nervures, and narrow margin, 

 deep black." [These semi-transparent yellow spots, which 

 render the insect so remarkable, are occasionally to be 

 found on the lower wings of Richmondia, and even near 

 the costa of lower wings of Priamus ; possibly also in 

 pronomus (under-side) ; and slightly indicated in Aruana. 



1 shall refer to them again in section 7 of this work.] 

 " Thorax black and hairy ; above greenish in the centre, 

 beneath with a lateral red spot." [The green mark in 

 the middle of upper side of thorax is of a rich shining 

 metallic green resembling the colour found on the elytras 

 of a gorgeous species of beetle belonging to the Rhyn- 

 copherous genus cyphus, and extends to nearly 3-4ths of 

 the length of the thorax, the upper part occupying nearly 

 the entire space between the tegular. Its greatest width 

 is a third of that of the thorax.] "Abdomen yellow, 

 with diffused lateral black spots." [These spots are 

 nearly subdorsal] . 



The differences between the S of this species and of 

 Priamus, which are noted by Gray, will also be referred 

 to in section 7 of this work. 



$ . Wings on both sides obscure fuscus. Fringe spots 

 coarsely white. Front wings with 2 anterior minute spots 

 in the cell (under the striga somewhat longitudinal) with 



2 others (above elongate) and 6 others exterior unequal 

 (in shape). These are ashy-white, broadly interrupted ; 

 below more distinct and spreading. Hind wings aLove 

 with an anal dirty yellow spot, and 4 other exterior spots 

 pointed, triangular, and curved inward (sinuate) ; within, 

 ashy white, outside with 5 apical of the same colour, and 

 6 costal, yellowish, adjoining each other. Undersides with 

 the spots more distinct in colour, yellow without, whitish 

 within. The anal with an asy lunule. Internal margin 

 joined. Thorax, above reddish black ; spot above, yel- 

 lowish. Below, sides entirely red (rufo) hairy; abdomen 

 yellowish, blackish at the base ; above, the back ashy, 

 below, with 5 lateral dots ; spots black in the middle, and 

 other two basal spots red. 



The type ? therefore differs in several particulars from 

 the specimen from which my fig. was drawn, but, as might 

 have been anticipated, not so much in the $ . The 

 central longitudinal mark on the thorax of $ is a brilliant 

 green (but not quite so intense as in the <? — the yellow 

 somewhat prevailing over the green. The acuminate 

 patches between the nervules of lower wings are a reddish 

 yellow (slightly suggesting the tints of the $ , the upper 

 parts of these of a sordid reddish yellow, instead of ashy 

 sordid white. The anal patches are also of the same 

 colour, as are the lunules of the outer margin between the 

 dentations. Only one ashy white spot is found in the 

 discoidal cell of upper wings, nearest to the 2nd branch 

 of the median vein. The ashy spots are rather more 

 prominent ; the abdomen is yellower, with brownish 

 cloudings above ; the underside of front wings with 

 markings almost identical in shape, size, and colour. The 

 under surface of hind wings more like that of the type ; 

 the anal lunule being yellowish instead of ashy. 



The vermilion on sides of thorax covers almost the 

 whole surface to the trochanters, and the abdomen ranges 

 from brownish red to greenish yellow. A second ? 

 in the Rev. Dr. F. A. Walker's coll. is rather darker, with 



smaller spots on the upper wings, but 2 or 3 spots within 

 the discoidal cell, that is to say it approaches the type 

 more nearly in character. A ? in the Brit. Mus. has the 

 upper portion of the yellow on the secondaries brighter 

 than in the type, while the general colour of the wings is 

 also paler. 



In a $ in the Brit. Mus. the orange band of Primaries 

 is of a deeper red than in that of the fig. In two others 

 in the Hewitson collection, the orange is yellower, and 

 the underwings more opalescent, ranging from yellow 

 orange to green ; the King's-yellow semi-diaphanous 

 spots of secondaries are only 2 in one specimen, and 5 in 

 the other, with an acuminate trigonal sinuate mark above 

 the round black spot below the discocellular nerve — there 

 being 3 others of the latter spots ; the black hind marginal 

 borders are much narrower on the under wing. The 

 median nerves are very black in one specimen ; the semi- 

 diaphanous spots absent from lower wings round the hind 

 margin, replaced by one largish black spot (flanked by 2 

 nearly obsolete black dots) nearest the costa. The black 

 of Primaries is really a very black orange brown. The 

 orange is deeper than in the type, and the black appears to 

 be shot with velvety purple in certain lights. The dimen- 

 sions of this latter specimen are : costa 86 ; abdomen and 

 antennae 36 ; breadth of upper wing 44 ; length of lower 

 wing 34, and greatest breadth of orange subcostal band 

 17 millimetres. Hab. Ternate. 



<?. In Mr. Oliver Janson's coll. much more lemon 

 yellow in sub-costal band than in Wallace's specimen's ; 

 the semi-diaphanous spots on lower wings are the same 

 in number but paler, and more like the ground colour, and 

 the yellow mark within the cell is longer than in that of 

 the figure. This is a bred specimen from Batchian. It 

 seems that specimens which have been bred from larvae 

 conveyed to Java and Amboyna become much lighter than 

 those taken on the wing by Wallace. Probably the 

 slight change of the food plant and geographical environ- 

 ment may account for this. It is an interesting fact, to 

 which it may be necessary again to refer in some other 

 place. 



$. In Hewitson coll. very red ; the green reflections 

 not so intense as in other examples ; the under wings very 

 deep copper red ; subcostal band much broader and more 

 excavated from lower part nearest the anterior angle ; the 

 4th subcostal nervule not black, while in the first specimen 

 of his series it almost becomes a black band of atoms, 

 much denser towards the middle ; on hind wings only 3 

 semi-diaphanous spots, i.e. within the cell, on the costa, 

 and between 2nd and 3rd subcostal nervules. On the 

 under surface these forma continuous patch, only divided 

 by the nervules (or veinlets as they would be most properly 

 called) ; on the under surface of superior wing the green 

 band extends over the lower half of the cell, with a 

 distinct trace at the edge of the upper half. [Wallace's 

 type has only a small blotch slightly suggestive of the 

 shape of a terebratulid shell of the Brachyopodous 

 Molluscaj . Hab. probably Batchian. 



3 . Contrast with the above a var. in Mr. Walter 

 Dannatt's collection. Colour of subcostal band lemon 

 orange ; of hind wings the same. Lower half of posterior 

 margin of Primaries with a broadish set of spots nearly 

 forming a band, composed of lemon-orange atoms situated 

 within the 2nd discoidal, and the 1st, 2nd, and 3rd median
