I first give M. Oberthur's original description of this 

 variety of Amp hrysus, which was published in his " Etudes 

 d'Entomologie," in 1879. The description applies only 

 to the 6* . It was reserved for Mr. Snellen to describe 

 the ? later on under the name of RitsemcB. 



" Tres cureiux Papillon, beaucoup plus petit que les 

 individus ordinaires d'Amphrysius, ayant le contour ex- 

 terieur des ailes inferieures plus profund, les parties 

 saillantes plus argues et les nervure peu courbees pres de 

 l'extremite. De plus, dans la partie jaune de 1' aile 

 inferieure, entre les nervures, on voit cinq taches noires 

 triangulaires ; la quatrieme surtout est tres grosse. Sur 

 les dessus de l'abdomen, deux taches noires soyenses se 

 detachent sur le fond fauve pale." (Catalogue Raisonne 

 de Papilionidae de la coll. de Ch. Oberthiir). 



$ . Anterior wings velvety black, with the adnervular 

 rays and the subcostal veins a rich silky yellow. These 

 rays only extend to the 2nd median nervule, whose par- 

 ticular ray forms only a small yellow pyriform spot ; 

 fringe-lunules white ; a thin yellow line borders the distal 

 end of the cell ; all the yellow rays are subdued by black 

 atoms ; the veins are all fairly prominent above the black. 

 Undersurface almost exactly as above, with the addition 

 of 2 faint yellow marks below the rays. Posterior wings 

 rich golden 3'ellow, suffused on the disc and at the distal 

 end of the cell by an emerald green tinge ; the veins all 

 vividly black ; the outer marginal black band is rather 

 narrow, and sinuate or dentate, with a rather long pointed 

 dentation at the anal angle ; the abdominal or inner 

 margin is broadly black, and there are 4 black cuneiform 

 marks between the veins of the disc, of which the 2nd 

 from above is the longest ; these are elegant in form, and 

 dotted with yellow atoms. Undersurface as above, except 

 that the intra-venal cuneiform marks are rather smaller, 

 and the 1st subcostal nervule is thickened in a black 

 mark towards the outer margin, the base is black, the 

 black marginal dentation at the anal angle is as short as 

 the others, and the broad abdominal fold is reddish- 

 brown ; fringe-lunules white ; abdominal fringe of long 

 hairs red. 



Head, antennae and thorax black ; eyes brown ; pro- 

 notal collar red ; abdomen pale fawn colour, silky, with 

 2 dorsal black, nearly rounded, spots ; the anal segment 

 with black dorsal triangulate mark : abdomen beneath 

 and on the sides greenish and golden yellow, with the usual 

 lateral row of black dots, and the incisures black ; anal 

 valves fawn colour ; thorax beneath black, with the pec- 

 toral red patch ; legs black. 



Length of costa of anterior wing 67, of outer margin 50, 

 and inner margin 40 mms. ; width of posterior wing 32, 

 and length 39 mms. Length of abdomen or antennae 26, 

 and of thorax with head 20 mms.

$ . Anterior wings, fuscous brown ; the adnervular 

 rays creamy-white, with brown scaling ; these rays com- 

 mence at the 1st median nervule, the initial rays being 

 broad, and the others becoming narrower till they become 

 at the costa thin streaks of white ; in length they nearly 

 reach the outer margin of the wing at near the apical 

 angle ; from the second median nervule to the submedian 

 nervure are also four short rays or light marks, varying a 

 little in size and shape, with a slightly sordid yellow tinge ; 

 1 -4th of the discoidal cell at the distal end is also creamy- 

 white, subdued by brown scaling ; the fringe-lunules are 

 thin and white. Undersurface as above, except that the 

 adnervular rays are purer, and the short rays or marks 

 are more yellow and five in number ; the pseudoneura, 

 except the central one, are almost invisible. 



Posterior wing : the cell diagonally and narrowly 

 fuscous brown from the base, followed by a creamy-white 

 patch in nearly 3-4ths of the cell, subdued by brown 

 scaling, and a yellow area of i-4th at the distal end ; 

 outside the cell from the 1st subcostal to the outer half of 

 the 2nd median nervure is a narrow area of yellow, sinuate 

 or lunate in the outer direction ; the remaining half of the 

 space between the 2nd and 3rd median branches and to 

 the submedian fold or sinus is creamy-white, subdued to- 

 wards the base, and reaching longitudinally down 2-3rds 

 of that part of the wing ; the abdominal marginal area is 

 fuscous brown ; the discal area of the wing is black, with 

 a submarginal group or band of small disconnected and 

 triangulate or cuneiform yellow marks, 12 in number, and 

 a thin streak of white atoms at the apical angle; the 

 fringe-lunules are prominent and white. Undersurface 

 nearly as above, but the yellow and light areas are only 

 slightly scaled at the base of the cell, and are shaded into 

 the yellow ; the submarginal band of yellow marks are g 

 in number, of which the first two are sublunate, between 

 the costal and 2nd subcostal veins, the 3rd and 4th 

 between the 2nd subcostal and discoidal veins, the 5th is 

 attached to the discoidal vein, the 6th and 7th are double 

 sized and cuneiform to the 1st and 2nd submedian, and 

 the 8th and gth— the latter a long yellow mark at the anal 

 angle — to the 3rd median branch ; there are also 2 sub- 

 marginal white marks of atoms united to the fringe lunules 

 of the lower part of the wing ; a brief line of yellow atoms 

 is also at the costa. 



Head, antennae and thorax black ; eyes brown ; dorsum 

 of abdomen fuscous brown ; pronotal collar red. Under- 

 side of thorax dark brown with the pectoral red spots ; 

 legs black; abdomen, subdorsum and sides greenish 

 yellow, with the usual black dots — the segmental incisures 

 brown.
