Rothschild, 1895; Novit. Zool. 2 (3): 355; (a): P. ambrax Hoisd., forma tyji. [cJ,?] M. The white area on the hindwings is inconstant in breadth and sliajie; mostly it extends in the cell about 2 uim. bevond the origin of the upi>er discoidal nervule, but often it stops at the base of that vein; the iiiternervular jiartsof the area are rounded exterioily, or straightlv cut off, or obliiiuely sinuate. Though there is never a coHspicuouri anal orange-red mark on the hindwings abo\e, some specimens from German New Guinea show distinct traces of the spot, which in P. ambraz egipius is so well and constantly developed. , Beneath, the hindwings have mostly only one orange-red spot, standing near the anal angle ; many specimens possess, however, a submarginal spot of the same red, or a whitish colour, between the lower median neryules. A maie from Waigeu is highly interesting, as it exhibits beneath four feebly marked, but large whitish discal markings, shaped as in the nude of F. polytes L., and standing between the submedian nervure and lower discoidal nervule. I propose to call this interesting (atavistic V) aberration — a2-ab. conspectus ab. no v. In many specimens of urahrax, especially in individuals from Waigeu, these spots are indicated by a few white scales. F. Upperside : the white area of the hindwings consists usually of sis (five extra- and one intracellular) spots in all, which are seldom separated from one another, as the veins themselves are nearly always completely covered with white scales. The intracellular spot is sometimes very much reduced ; the extracellular white markings are occasionally also very small, and are often partly replaced by red ones ; that between the discoidal nervules is not seldom absent. In a few examples the white area is connected with the costal margin by means of two additional white markings (compare ? of P. polytes L., p. 348). The red colour behind the posterior part of the white area extends mostly from the suliniedian vein beyond the second median nervule ; sometimes it reaches the upper iiiedian nervule, while in other individuals it scarcely reaches the second median branch ; the nervules traversing the red patch are seldom white. There are from one to three submarginal red sjiots, besides a red marginal mark between the lower median and the submedian veins which is mostly joined to the large subanal red spot in the same cellule. A specimen from Kedscar Bay, British New Guinea, has five submarginal spots, and leads over to P. (mibrux eyipius Misk. from Queensland. Underside: as above; the series of snlimarginal s]iots of the hindwings is, however, mostly complete ; sometimes I he two spots lietween the subcostal and second discoidal veins are wanting. l-5ois(luval attriljutes to his P. orophancs a series of marginal (recte submarginal) lunules on the upperside of the hindwings, of which the exterior (rede anterior) ones are \ery little marked. I am not quite convinced that orophnues is the fciiude of the present race of P. arabrux, but believe that it belongs to P. ariibrax epiTUS Wall.; as the description is, however, not sufficient to solve the question, and the type apparently is lost, it is best to treat oraphdues as a synonym of ambrax.
