﻿POMPEOPTERA CRITONOIDES. 



Ornithoptera Criton Critonoides, Fruhstorfer, " Societas Entomologica," of Zurich, XVIII., p. 50, (1903). 



$ . Anterior wings a rich velvety black, with steel-blue 

 reflections ; quite immaculate, and the veins hardly dis- 

 tinguishable. Undersurface shining black ; the adnervu- 

 lar rays only reach to the upper side of the 3rd median 

 nervule, and are light blue ; at the distal end of the cell 

 the light blue marks are divided by the pseudoneura into 3 

 parts, the upper section being the largest and broadest, or 

 i-3rd the cell length. 



Posterior wing : one half the cell rich silky yellow, with 

 greenish reflections, curved inwardly towards the base ; 

 two-thirds of the discal area of the same yellow, its out- 

 line following the outline of the outer margin, and leaving 

 a broad submarginal i-3rd black ; all the rest of the wing 

 is also black. Undersurface as above. 



Head and thorax black ; pronotum with red collar ; 

 abdomen silky black above, yellow beneath. 



Length of costa 67 mms. ; of outer margin 51, and of 

 inner margin 35 mms. The inner margin is nearly 

 straight. Length of posterior wing 41, and width 29 mms. 

 Length of abdomen or antennae 29 mms. ; of thorax with 

 head 20 mms.

% . Anterior wings silky dark brown ; the adnervular 

 rays just distinguishable in a slightly silky brown. Under- 

 surface as above, except in being of a lighter brown, 

 rufus-tinted ; the adnervular rays faintly indicated by 

 gray atoms : the lighter marks at the distal end of the 

 cell also treated in the same way. 



Posterior wings very black and silky ; a yellow mark 

 incurved towards the base, from the distal end of the 

 cell, one-fourth from the base ; the silky golden yellow of 

 the disc only occupies 2-5ths — thereby constituting a very 

 broad submarginal black band, with 3 almost obsolete 

 small yellow discal spots on the upper part of the wing — 

 indicating the commencement of a possible submarginal 

 transverse band of yellow cuneiform spots. The creamy- 

 white outer-marginal fringe lunations are very thin. 

 Undersurface as above, except that the yellow areas are 

 outlined whitish, and the transverse band of cuneiform 

 spots, though small, extend round the wing, and a small 

 group of white atoms is present outside the 3rd median 

 nervule. 



Head and thorax black ; eyes, nitid brown ; pronotum 

 with obscure red collar; abdomen above silky warm 

 brown ; beneath yellow scaled, with large lateral black 

 dots, and subdorsal black marks on the articuli. 



Length of costa, 66 mms. ; length of outer margin, 47 

 mms., and of inner margin, 37 mms. Greatest length of 

 posterior wing, 42 mms. ; greatest width, 29 mms. 



Length of abdomen or antennae, 26 mms. ; of thorax 

 with head, 17 mms. 



The inner margin of the anterior wing is nearly straight.

S . A remarkable abnormal variety. Anterior wings : 

 nearly one half the cell (outer portion) creamy white ; the 

 white continued into the disc so as to occupy a consider- 

 able portion of its area — the adnervular rays (which 

 extend nearly to the outer margin of the wing) being con- 

 fluent with it ; the submarginal brown-black divided into 

 a series of long indentations — gradually increasing in 

 length towards the costa ; slightly more than half the cell 

 from the base black as is also the rest of the wing ; all the 

 dark outlines are extensively scaled with white atoms ; 

 the marginal light lunations form a continuous buff white 

 line up the posterior margin ; the veins all very prominent. 

 The undersurface of the wings almost exactly as above in 

 colour and pattern. 



Posterior wings, with a central discal area of buff-white, 

 slightly yellow tinted, occupying one half the length 

 of the disc, and extending from above the 1st discocellular 

 to the 3rd median nervule; the remainder of the 

 disc is brown-black, interrupted nearly midway by a 

 transverse band of adnervular cuneiform creamy-white 

 marks, extending from the anal to the apical angles ; about 

 1 -4th of the cell from the distal end creamy-white ; all 

 the remaining area of the wings brown-black, with a slight 

 line of white atoms along the submedian fold. The pos- 

 terior marginal lunations with a continuous outline of 

 buff-white. Undersurface as above, except that the light 

 area is following by a transverse row of suborbicular 

 black spots, scaled all round — followed by a transverse 

 light band of cuneiform marks, and finished by the sub- 

 marginal lunate black band, rather extensively scaled with 

 white atoms ; part of the submedian area is also white, 

 with a black orbicle.
