mmitrmizieri has the priority of date. P. ulyssimis Wesfw. is exactly identical with 

 P. niontrousieiH Boisd. P. chaudoiri, to which Felder gave the erroneous locality 

 "Moluccas," and which, according to the type-specimen in my collection, came 

 certainly from New Caledonia, differs from ty|)ical moniromieri in having four 

 cottony stripes on the forewings and in having the blue colour more reduced; the 

 other characters by which Felder {Reise Novara, I.e.) distinguishes chaudoiri from 

 niontrouziei'i are individual and partly imaginary. In P. tvestwoodi Oberth. the 

 blue area of the wings is still more reduced than in chaudoiri, and the vudes have 

 four or five cottony stripes ; on the other hand, the blue colour is much more e.itended 

 and the cottony stripes have almost or entirely disappeared in West wood's ab. ulyssellus. 

 Between the two extreme forms, tvestwoodi and ulyssellus, there exist every inter- 

 gi'adation, so that there is no doubt that ail these forms belong to one species. As 

 I have not received westuvodi from the island of I.ifu, where clumdoiri and ulyssellus 

 fly together with typical montrouzieri, it seems to me not improbable that westwoodi 

 inhabits the main island of New Caledonia, and may turn out to be a local form ; 

 from this reason, and because chaudoiri stands intermediate between moittrouzieri 

 and weshvoodi, I keep westwoodi Oberth. separate under a varietal name, and treat 

 chaudoiri as a synonym of montrouzieri.

Cottony stripes almost or entirely absent. 



In a specimen in my collection there is no trace of the cottony stripes visible 

 even under a lens; in the type of idy.ssellus in the British Museum the stripes are 

 not entirely obliterated. The blue region of the wings is in my specimen much 

 enlarged, the black border of the forewings being of a breadth of 5 mm. at the lower 

 median nervule, and extending a good way (4 mm.) beyond the end of the cell.
