486 Mr. A. G. Butler's Descriptions 



Expanse of •wings, 4^ inches. 



Hab. — Luzon, Philippines (Semper) . B. M. 



I believe the large patch on the front-wings to be 

 natural, it is perfectly regular ; the species, however, is 

 quite distinct from A. rhidippus, if this marking be left 

 out of the question. 



2. Amathusia virgata, n. sp. 



Allied to A. Phidipims, wings above of a redder tint, 

 the bands much less distinct ; below pale ochraceous, 

 the basal area nearly white, with the bands, five in 

 number, of an olive-brown colovir, the fifth restricted to 

 the discoidal cell of front-wings, the third and fourth 

 uniting so as form a large triangular patch below the 

 median nervure of hind-wings ; the central band dark 

 olive-brown, narrower and more irregular than in A. 

 Phidippus, and succeeded by a broad band of olive- 

 brown, paler exteriorly, and divided through the centre 

 by a wavy streak of pale rosy-brown; caudal patch 

 black, white spots very distinct.

Professor Westwood, in his Cabinet of Oriental Ento- 

 mology, gives an outline figure of the front- wing of 

 Zeuccidia, in order to show its distinctness from that of 

 Amathusia, and remarks, p. 40, "This outline figure re- 

 presents the fore-wing of Zeuxidia Luxerii, mentioned 

 above, in order to show the very curious arrangement of 

 the veins, whereby it will be seen that the folding of the 

 wing marked * (which in Amathusia follows the long 

 branch marked f) is here converted into a foiu-th branch 

 of the great median vein, by means of a distinct twig, 

 which connects it therewith." 



The above observation is incorrect, as may be discover- 

 ed by the application of a little benzine to the wing of 

 Zeuxidia, which being thus rendered transparent, exhibits 

 a spur upon the outer edge of the third median branch, 

 but terminating as it reaches the mng-fold, which there- 

 fore is not actually converted into a fourth median branch ; 

 the point whence this spur issues in Zeuxidia is some- 

 Avhat prominent in Amathusia, so that it is not impossible 

 that a species possessing the spur may yet tui'n up ; the 

 males of Zeuxidia, which are far more numerous than the
