﻿RECAPITULATION OF THE PRINCIPAL CHARACTERS OF THE 



AMPHRYSUS GROUP.* 



A comparison of the different forms of the Amphrysus 

 group will give us the following results, by which we may 

 be able to judge of their relationship to each other. 



(a) . The type species Amphrysus 6* with velvety black 

 anterior wings, and all the adnervular rays and marks in 

 both surfaces, yellow ; the fringe lunules on both surfaces 

 yellow ; all yellow marks very prominent. Posterior wings 

 yellow, with moderately broad black lunate border ; with- 

 out black maculae, except one elongate spot at the anal 

 angle united with and above the marginal lunation or 

 dentation (on the under surface of the wing this mark is 

 onby faintly indicated by black atoms or scaling) ; the inner 

 or abdominal marginal fold is broad and black above, 

 partly rufous on the underside ; abdominal fringe, rufous. 

 Undersurface of wing, similar. Head, antennas and 

 thorax, black ; pronotal collar red ; abdomen, greenish 

 yellow, with a broad central longitudinal black and rufous 

 vitta above. 



2 . Anterior wings on both surfaces, rufous brown ; 

 with sordid white and yellow discal rays, and the distal 

 end of the cell sordid white ; on the undersurface the light 

 areas are yellow white ; fringe lunules white. Posterior 

 wings, 2-3rd of the cell and i-3rd of the disc, yellow ; base 

 of the wing and subcostal area, rufous brown ; outer 2-3rds 

 of the disc black, with a row of yellow marks midway ; the 

 submedian area, rufous brown, and above the submedian 

 fold very sordid brown yellow ; fringe lunules, white ; 

 abdominal fringe, rufous or burnt sienna. The under- 

 surface of the wing as above, except that the yellow area 

 is whitish yellow. Head, eyes, antennae and thorax as in 

 the 9 ; abdomen, rufous brown above ; yellow below. 



(b) . var. Ruficollis. 3- . Anterior wings black ; the ad- 

 nervular rays and cell marks (at distal end) faintly orange 

 yellow and white, and not so prominent as in the type 

 form ; fringe lunules, white, being only thin outlines; under- 

 surface the same. Posterior wings, rich silky golden 

 yellow, with the outer marginal outline black, with the 

 submarginal row of black lunations situated midway from 

 each vein ; an elongate black spot at the anal angle ; the 

 base of wing, rufous above the precostal cell ; the veins 

 rather curved, thin, black, and very graceful. Under- 

 surface similar ; inner margin, sienna brown on both 

 surfaces ; abdominal fringe, black. Head, antennae and 

 thorax, black ; eyes, red brown ; pronotal collar, red ; 

 abdomen, greenish lemon-yellow, with fleshy pink dorsal 

 vitta, and white anal valves. 



(c) . Sub. var. Flavicollis $ . Anterior wings, black ; all 

 the yellow rays and marks yellow, with white terminals 

 and prominent ; outer marginal fringe lunules thin and 

 white. Posterior wings and abdomen as in Ruficollis : head, 

 eyes, antennae and thorax the same as in Ruficollis, except 

 that the pronotal collar is yellow instead of red. 2 . 

 Anterior wings, pale amber brown, and brownish-grey cell, 

 shaded darker towards its base. The undersurface 

 similar. Posterior wings with the cell, costa, and outer 

 area of median and other veins, yellow; the disc is oc- 

 cupied with black to 3-5ths of its area, and contains a 

 submarginal band of yellow marks ; the base of wing, 

 fumous brown, as is the abdominal area. Undersurface 

 similar ; abdominal fringe short and dark ; head, eyes, 

 thorax, &c, and collar, as in the 3 ; colour of abdomen as 

 in the 3 . 



The 2 2 oiRiificollis andFlavicollis differhomthoseofthe 

 type form in having the costa of the anterior wings rather 

 more pointed at the apical angle, and in the very different 

 appearance of the vars of submarginal lunate spots of the 

 posterior wings. The 2 of Flavicollis bears rather a strik- 

 ing resemblance to the 2 of Andromache. 



(d) . var. Cuneifera. 2. Anterior wings, silky black ; the 

 light rays and marks, yellow, subdued by black atoms ; 

 undersurface the same. Posterior wings, rich silky yellow, 

 with lemon-green shading and reflections ; a discal row of 

 four cuneiform black marks ; outer marginal band broadly 

 black and sinuate ; at the anal angle the black division is 

 sharply dentate, but only faintly shown on the under- 

 surface ; base of wing, dark brown ; abdominal area 

 black ; fringe lunules white (on both wings) ; abdominal 

 fringe, burnt sienna-red. Head, thorax, &c, as in the 

 type form ; pronotal collar, red ; abdomen, rufous brown 

 above ; with lateral yellow outline and two dorsal black 

 spots ; anal valves, grey and black ; underside of thorax 

 with lateral red patches ; of abdomen, yellow green ; 

 undersurface of wings as above. 2 . Anterior wings, 

 rufous brown, with greyish-ochraceous broad rays, and 

 yellow marks ; distal end of cell broadly grey. Under- 

 surface similar, but the light parts are purer in colour. 

 Posterior wings with the greater portion of the disc black, 

 and a submarginal band of small yellow marks ; the distal 

 end of the cell and a small portion of the disc yellow ; the 

 remainder of the cell and disc grey, subdued by scaling ; 

 tho base of wing and subcosta, and inner marginal area, 

 rufous brown ; fringe lunations conspicuous and ochra- 

 ceous-grey ; abdominal fringe, burnt-sienna. Under- 

 surface of wings nearly as above, the lighter parts purer 

 in colour, with congeries of white atoms. Head and 

 thorax, &c, as in the 3 ; abdomen, brown above, greenish 

 yellow beneath. 



(e) . var. Sumatrana. 3 . Anterior wings rather narrower 

 and longer than in the other forms ; black, with only 

 faint indications of the yellow rays and marks ; under- 

 surface as above. Posterior wings yellow, shaded with 

 lemon green, and exceedingly like the wings of Cuneifera 

 except in the absence of the cuneiform marks ; under- 

 surface as above, except that the abdominal marginal 

 fringe is very whitish red. Head, thorax, &c, like the 

 other form, but with no visible red collar above, but with 

 red pectoral patches ; abdomen, very rufous or flesh- 

 coloured grey, with lateral large spots, black dots, flesh- 

 coloured anal valves ; underside, yellow and greenish. 

 2 [A bold, strong-loooking insect.] Anterior wings, warm 



dark brown ; with all the rays and marks sordid yellow 

 grey ; undersurface of wings, warm dark brown, the yellow 

 marks all brighter and a purer yellow. Posterior wings 

 with yellow disc and the distal half of the cell yellow ; a 

 band* of suborbicular black spots, followed by a scalloped 

 submarginal band of yellow ; the remainder of the wing 

 velvety black ; the abdominal marginal area rufous, with 

 yellow atoms ; undersurface, similar. Head, thorax, &c, 

 black on both sides ; abdomen, dark brown above, yellow 

 beneath. Thorax, with no pectoral red patches. 



(f) . var. Palabuana, Friihstorfer, from Palabuan, S. W. 

 Java, anterior wing of the 3 with the adnervular rays 

 almost dark reddish-brown. 



(g) . var. Olympia 2 , Honrath, from S. E. Borneo, is 

 only a slight variety of Flavicollis.
