species of Western Pacific Rhopalocera. 363 



the 2nd segment, in a line with the mouth, a somewhat 

 triangular blotch of a deep velvety madder-brown runs 

 obliquely upwards through 3rd and 4th to base of 5th 

 segment, and connects over the back with a similar 

 marking on the other side ; this stripe is continued 

 through the 6th segment, where it meets the broad 

 shining white stripe, which runs above claspers to vent ; 

 the triangular blotch is bordered above by a pale golden- 

 green line ; on 8th and 10th segments a somewhat 

 triangular madder-purple blotch, bordered above by a 

 narrow white stripe ; head shining brownish green, with a 

 narrow white line down centre of face, and a V-shaped 

 mark over mouth ; legs pale reddish brown ; ventral 

 and anal claspers smoky black ; two bluntish orange- 

 coloured spines upon the 2nd segment, just behind the 

 head, and at the base of each of these a minute orange 

 tubercle, between which, and a little to the rear of the 

 spines, is the nuchal valve, through which, when the 

 larva is irritated, the usual tentacles are emitted ; the 

 tentacles are of a deep carmine, and give off the 

 accustomed pungent odour ; on 3rd and 4th segments a 

 pair of subdorsal blunt spines ; on 5th, and from 9th to 

 13th segments, a single subdorsal spine on each side ; 

 all the spines orange, faintly tipped with black. 



These larvse varied a good deal ; in some the oblique 

 stripes and triangular blotches were entirely absent, the 

 whole surface, above the white spiracular stripe, being of 

 a beautiful green, more or less marbled or streaked with 

 darker and golden greens ; while one or two larvse I took 

 had the markings upon one side only ! a circumstance 

 I do not remember to have met with before. 



The chrysalis is from 30 mm. to 35 mm. long, angu- 

 lated ; head very strongly bitid, the extreme points 

 tipped with black ; back gradually arched ; sheath of 

 haustellum prominent ; costal edge of wing-case ridged ; 

 body pinched in at centre ; whole surface a beautiful 

 golden apple-green ; spiracles well marked, darker ; seg- 

 mental divisions clearly defined, pale yellowish brown. 



The chrysalis is invariably attached to the midrib of 

 a leaf, while those of Papilio Sclimelizi are just as in-, 

 variably attached to a stem. 



There was a peculiarity about these larvae which I 

 have not seen mentioned as having been noticed in the 

 larvse of any other species of Papilio. On the crown of 

 the 2nd segment, just behind the head, there is a horny
