﻿POMPEOPTERA STAUDINGERI. 



Pompeoptera Staudingeri, Rober, " Entomologische Nachrichten," page 369. (1888). 



<? . Primary wings above velvety or silky black. The 

 light discal adnervular rays are sufficiently prominent, 

 creamy grey towards the outer margin ; bluish dark grey 

 towards the discoidal cell ; the cell is immaculate black, 

 with the faintest indication of a grey outline at the distal 

 end ; the pseudoneura in the cell are fairly prominent ; 

 the veins are all very prominent ; the outer marginal 

 fringe with creamy-white lunules. 



Under surface of primaries very dark and silky brown ; 

 the adnervular rays very light greyish white, free from 

 dark scaling (contrary to what they are on the upper sur- 

 face), and extending almost to the outer margin ; there 

 are no white marks on the disc below the 3rd median 

 nervule ; the cell which is black with 3 white streaks 

 from midway to the distal end, whereof the first and third 

 are the broadest ; the marginal fringe lunations rather 

 whiter than above. 



Secondary wings, deep velvety or silky, black ; with a 

 discal area of rich golden yellow, extending from the 

 subcostal nervure to the 3rd median nervule. This area 

 or yellow band occupies exactly half the surface of the disc 

 above the 3rd median nervule, the remainder of the disc 

 consisting of a broad submarginal black band ; the distal 

 i-3rd of the cell golden-yellow ; the submedian and inner 

 marginal areas black, the line indicating the position of 

 the inner marginal fold sufficiently visible ; the usual 

 fringe lunules are absent ; a number of light hairs flow 

 from the base of the wing over and below the cell. 



Undersurface of wing nearly as above except that the 

 yellow area between the costal and 1st subcostal veins 

 occupies less space than on the upper surface, is suffused 

 slightly with a greenish tint, especially nearest the costa, 

 a thin line of yellow atoms is in the black beneath the 

 subcostal, a few similar atoms are in the cell close to the 

 yellow area, a small group is below the 3rd median ner- 

 vule, and two thin lines of atoms follow the course of the 

 2nd and 3rd median nervules into the submarginal black 

 band. 



The posterior wings are delicately lunate on the outer 

 margin, the light fringe lunules are visible on the under 

 surface. The outer margin of the anterior wing is 

 nearly straight. The inner marginal fringe of brown hairs 

 is fairly conspicuous. Head, antennae and thorax are 

 velvety black ; the eyes rufous brown ; the pronotal collar 

 red ; abdomen dark rufous brown. Beneath, the legs are 

 long, graceful, and slender ; the thoracic red patch very 

 prominent and extensive on both sides ; the dorsal part of 

 the abdomen is yellow. 



Length of costa of anterior wing 57 mms ; of outer 

 margin 44 mms. ; of inner margin 31 mms. Greatest 

 length of posterior wing 40 mms. ; greatest width 26 mms. 



Length of antennae or abdomen 25 mms. ; of thorax 

 with the head 20 mms.

Habitat : Selaru, Loeang Island, Babber. 

 In the Tring Museum. 



? . Anterior wings rufous brown, not very dark in tint ; 

 the adnervular light rays are very broad and conspicuous, 

 and extend from the upper to the lower part of the wing 

 — that is to say, they border all the veins and the sub- 

 median fold from the costa to the submedian nervure, and 

 reach nearly to the outer margin in their course ; they are 

 rufous grey in tint, and subdued by brown atoms : the 

 spaces between the lower ones are also lightly sprinkled 

 with grey atoms on the brown of the disc ; more than half the 

 discoidal cell is occupied from the distal end by a streaky 

 grey patch of atoms enclosing a dark patch ; the veins 

 are all very obtrusive ; the fringe lunules greyish white. 



Undersurface as above, except that the light discal rays 

 are more rufous grey, and purer in tint, and not subdued 

 by dark atoms ; the light cell area is as above, slightly 

 more extensive, with some dark atoms uniting the basal 

 brown with the distal white. 



Posterior wings deep silky or velvety black ; only a very 

 limited area or discal band of golden silky yellow occupies 

 about i-5th of the disc from the 1st subcostal vein to the 

 submedian fold, the latter section subdued with white ; the 

 distal half of the discoidal cell is also of the same yellow ; 

 the inner, or abdominal margin is rufous brown, with a 

 marginal white streak, and some white atoms ; the pre- 

 costal cell is rufous brown ; all the rest of the wing is deep 

 silky or velvety black, with bluish reflexions ; the fringe 

 lunules are dark grey; a mass of dark hairs flows over part 

 of the golden areas from the base. 



Undersurface as above, except that the yellow is not so 

 pure, and the black slightly rufous towards the outer margin ; 

 there are two adnervular discal yellowish spots midway of 

 the disc on the 2nd subcostal, the discoidal, and 1st 

 median veins ; and the 2nd and 3rd median nervules are 

 slightly bordered with light yellow atoms nearly to the 

 outer margin. 



The outer margin of the anterior wing is nearly straight 

 (or only slightly lunate) ; the posterior wing is more 

 lunulate. 



Head, antennae, and thorax, warm velvety black ; eyes 

 rufous brown ; abdomen above, rufous brown ; lateral 

 parts more rufous, and with lateral black dots on yellow 

 and white atoms above the yellow ; subdorsum yellow, with 

 two rows of black marks between the articulations. 

 Thorax with prominent red pectoral patches. Legs, nitid 

 black and slender.
