(1) That Liiiiie, when describing his Iwlemi in IT.iS, had no specimen before 

 hiua, else he would not have put that species amongst the Equites Achivi; 



(2) That Linne described his Iielrno in 1758 from Meriaii's figure only, which 

 is Cramer's poinpeus ; 



(3) That Linne found in ITUi the Amlioina insect in the ]\Iuseum of the Queen 

 Ludovica Ulrica, and mistook it for the insect figured by Pierian and named heleiid 

 in 1758. 



I am very sorry to state that, in consequence of what I have explained here, the 

 name of fielena (L.) must be applied to the insect described by Cramer as (P. E. T.) 

 jjomjjeus, and that for the Moluccan insect the name which comes next in priority 

 must stand. Now the feiivde of the Moluccan Papilionid in question received the 

 name of oblongomaculatus Goeze in 1779; Cramer pulilished the same sex under 

 the name of ariiphimedon, most probably also in the year 1779. Which name has 

 the priority? The "Vorrede" of Goeze's Ent. Beytr. III. 1 is dated " Vor der 

 Michaelismesse_ 1779," and has been written after the volume was printed (of. 

 " ^'on■ede ") ; (ioeze's book came, therefore, out at the " jNIichaelismesse " — i.e. in 

 the middle of the year 1779. Cramer's Vol. III. is dated 1782; the first plates of 

 Vol. III. have, however, been quoted by Goeze in 1780 and by Fabricius in 1781, .so 

 that undoubtedly a number of Cramer's plates of \o\. III. must have been published 

 at least before the " Michaelismesse " of 1780. I cannot find any reference to the 

 exact appearance of Cramer's plates of Vol. III., and as I think it only just that in 

 all cases of doubtful priority the name of that author must have the priority who 

 dated his publication, I am forced to enumerate the insect in question under Goeze's 

 name of ohlongoiiKiciddtus. 



This species occurs in the i^outhern Moluccas, Celebes, and New Guinea, and 

 must be divided into four subspecies : — 



(«) : T. ohlonijoiiwc^datus (Goeze) from Amboina, Ceram, Banda Islands ; 



(6) : T. ohluiviwiivicidatan boarnensls (Wall.) from the Island of Burn ; 



(c) : T. oblowjo'inaculatus eelebensis (Wall.) from Celebes and Saleyer; 



(cZ) : T. obloH<jo)nacid(dus papuensis (Wall.) from New Guinea. 



In the Northern Moluccas there occurs another species \_T. criton (Feld.)], while 

 on the Ke}- and Am Islands no yellow Troides has hitherto been found. 



(") : T. oblongomaculatus (Goeze), forma typ. [J, ?, metam.]. 



cJ. The median and discoidal nervules on the underside of the forewings are 

 mostly bordered with a white scaling, which is, however, seldom very obvious, and 

 sometimes entirely absent. The first .spot of the yellow area of the hindwings, 

 situated between the costal and subcostal nervules, is in some individuals four times 

 as large as in others; sometimes the black colour of the base is extended along the 

 subcostal nervure as far as the origin of the subcostal nervule ; in other examples 

 the submedian nervure and upper discoidal nervule are broadly, but quite iiTegularly, 

 black; there is occasionally a black irregular spot in the apex of the cell, and also 

 sometimes some niinute patches in the yellow discal area outside the cell. The 

 yellow marking between the median and snlimediau norvures is narrow, but mostly 

 of about the same length (15 mm.) as the preceding mark ; in one of my specimens 

 it is, however, reduced to two minute spots. 



?. The whitish adnervular streaks of the forewings above are often very feebly 

 marked; in other individuals the whitish colour is so much extended as to occupy 

 the outer two-thirds of the wing, exclusive of the costal and outer margins and the
