connection as to habitat or time of appearance ; the black on the upper side 

 is not so much diffused in all $ as in the specimen figured. ' The larva taken 

 at the place just mentioned was found living on a climbing plant which has 

 been identified as Melodinus Laevigatus B1. It is intermediate between the 

 EuPLOEA and the Danais type, velvety black with a milky white transverse 

 band on each segment. It has only two pairs of processes, also black but red 

 at the base. The anterior pair, projecting from the second thoracic segment, 

 is considerably longer than the posterior pair which is situate on the penul- 

 timate segment. The head is shining and furnished with two sharp points. 

 The pupa is of the Danais type, whitish green with a black caudal hook and 

 several round black dots. A row of 8 such dots occurs at the boundary ot 

 the thorax and abdomen, the others being distributed in 6 pairs on the thorax. 



Genus DANAIS Latr. ') 



Fruhstorfer (Seitz, Grossschvi d. Erde, Danaidae, /. 193) states that 

 Danais (ANOSfA) Plexippus L., Archippus F., Erippus (Cram.), of American 

 origin is said to have spread even to Java. The same statement has been 

 made by various English and American authors ; the first to assert this appears 

 to be KiRBY. It is, however, probably based on a misconception, due, most 

 likely, to the fact that D. Genutia Cram, has been referred by some entomo- 

 logists to D. Flexippus L. The true D. Plexippus L., as has already been 

 mentioned in the introduction, has spread from America westwards over the 

 Pacific islands but from Australia only northwards apparently and subsequently 

 again eastwards. For specimens are known from new Guinea, the Moluccas, 

 the Talaut islands. North Celebes and Southern China, but I have never seen 

 any from one of the islands in the sea of Java anymore than from Java, 

 South Borneo, South Sumatra nor from South Celebes, although I have myself 

 during five years collected butterflies in that region, and such a large insect — 

 so conspicuous by its colouring — which, moreover, occurs in the districts 

 near the coasts, could not have escaped attention. 



•) In the Leyden Museum is a specimen of Danais Isimare Cram, which is said to have 

 been forwarded from Java by the late Reinvvardt. Since no other specimen of this species, to 

 my knowledge, from Java exists and in view of the unreliable character of many of the old 

 labels in this museum, I do not propose, for the present, to include the species in the Java fauna. 

 Fruhstorfer, (Seitz, Grossschm. d. Erde) also mentions a form of D. Affinis F., called Kasirensis 

 by him, as doubtful for Java, a couple of specimens of which he states to have seen whose 

 origin, however, he doubts. I do not, therefore, propose to include this species either in the fauna 

 of Java for the present.
