﻿TROGONOPTERA TROJANA. 



O. Trojana, Honrath, Berliner Ent. Zeitschrift, Vol. XXXIII., p. 3, iS86. 



Since the publication of pages 5 and 6 of this volume, 

 and of Plate 27, in which the S of this species was 

 described and figured, I have been enabled to study the 

 ? of T. Trojana, by the kindness of the Hon. Walter 

 Rothschild, the results of which I now present. 



2 Anterior wings a very warm rufous brown, allowing 

 all the veins to be very prominently seen ; the pseudoneura 

 well expressed in the discoidal cell; the submedian and 

 marginal folds also well accentuated ; a transverse band 

 of phylliform marks on the disc, extending from the inner 

 margin to the 3rd subcostal branch ; the first three from 

 the lower part of the wing are large and delicately green, 

 with whitish and bluish suffusions towards the outer- 

 marginal ends, strongly divided by the veins, which 

 thereby form their midrib ; the first or lowest of these 

 three is as leaf-like as those of T. Brookeana, but larger — ■ 

 situated on the submedian nervure : the 2nd and 3rd are 

 larger and narrower, situated on the 3rd and 2nd median 

 nervules ; the 4th, 5th, and 6th are nearly confluent with 

 each other, rather longer and broader, ochraceous, or deep 

 creamy white on the 1st median branch, and 2nd and 1st 

 discocellular nervules ; the remainder constitute a light 

 creamy patch extending to the 3rd submedian branch — 

 only divided from the others by the veins : these are all 

 slightly tinted with green or bluish green at the ends 

 towards the discoidal cell ; a little cluster of delicate light 

 hairs is situated at the base of the submedian vein, flowing 

 over on to the lower wing. These are so delicate as to be 

 only seen by careful examination. 



Posterior wings with a rather darker rufous brown than 

 that of the anterior ; the centre of the wings, or an area 

 which includes the whole of the discoidal cell, and about 

 1 -4th of the disc is violet blue, shading outwardly into 

 blue-green, and rich golden green, subdued by dark atoms 

 - — the violet blue flowing into darker or lighter, as the 

 insects are moved about in the light, and towards the 

 base of the cell shading into dark blue or brown ; a discal 

 or submarginal row of diamond-shaped sordid light spots 

 on the first five veins, and a continuous creamy-white 

 patch crosses the subcostal nervure, and extends nearly 

 to the anterior angle or apex ; a few white atoms on the 

 blue at the distal end of the cell ; a bright greenish blue 

 stripe is found between the 3rd median branch and the 

 median nervure, which, in some positions, becomes en- 

 tirely blue or blue green the whole length to the base of 

 the wing — the abdominal margin is also of the same rich 

 colouring — sometimes forming one continuous area of 

 colour to the subcostal nervure ; the outer margin of the 

 wing is lunate, with light fringe crescents. 



The anterior wing margin has no fringe crescents. Under 

 surface of anterior wing nearly as above, except that some 

 ray-like suffusions of violet extend along the pseudoneura 

 of the cell : the costa is violet blue : and the space 

 between the 3rd median branch and the submedian 

 nervure is shot with violet blue and green from the base 

 to one half of the disc : the leaf-like discal markings are 

 creamy-white, and all confluent except that one on the 3rd 

 median branch ; and only a faint light half-mark represents 

 the green leaf-like mark of the upper submedian surface, 

 a patch of green-blue atoms are also between the rib and 

 3rd median branches. The veins are all well accentuated, 

 and, as on the upper surface, shot with blue. 



Posterior wing : the under surface of which is warm 

 brown, deeper in tone towards the hind margin ; with a small 

 atomic blue spot near the precostal nervure ; and another 

 similar mark at the base of the wing ; a submarginal or 

 discal band of cream white marks, nearly continuous, 

 strongly lunate without and almost enclosing a row of 

 sub-orbicular darker patches within ; the marginal fringe 

 of both wings is a narrow graceful line of faint creamy 

 white. All the wings above and below exhibit a slightly 

 light sheen when moved about. 



Head, antennae and thorax velvety black ; abdomen 

 dark rufous brown all over, with a slight sheen of bluish 

 white ; pronotal collar broadly scarlet-crimson, as in 

 Brookeana, with lateral red patches between all the legs. 



Length of abdomen and antennae nearly the same, or 

 35 mms. ; of head with thorax 24 mms. ; of costa approxi- 

 mately 94 mms. ; of outer margin approximately 67 mms. ; 

 width of wing at the base 7 mms. ; greatest width of 

 posterior wing, 43 mms. ; greatest length 57 mms.

Habitat : Palawan, Philippine Islands. 



Only on the under surfaces of the wings does this species 

 slightly resemble those of T. Brookeana 2 , whilst in no 

 respect are they like those of the <? of either species ; the 

 S of Trojana is also a bolder, larger, and more gracefully 

 formed insect than either the $ or 2 of Brookeana.
