also two bristles on each side of the anus, altogether twenty-six 

 bristles ; the mediodorsal stripe is dilated somewhat into a small 

 diamond pattern; segmental sutures strongly marked; ventrum, 

 legs, and prolegs yellowish white. The caterpillar is sluggish 

 in movement and drops from the leaf by a silken thread when 

 disturbed. 



Pupa. — The larva seems to spin its cocoon on the upper sur- 

 faces of such leaves as camellias or oak bushes. The cocoon is 

 somewhat boat-shaped and is placed with the flat surface (Plate 

 III, fig. 9) resting on, and parallel with, the midrib of the leaf, 

 the sides of which are drawn together and give support to the 

 sides of the cocoon which adhere to the drawn-in leaf. There- 

 fore, only the curved keellike dorsum (Plate III, fig. 8) of the 

 cocoon is exposed to view, while the rest is concealed by the leaf. 

 The cocoon is dirty white and is parchmentlike in texture, being 

 moderately tough. The pupa is ringed and streaked with golden 

 brown, dorsally of a yellowish golden tinge, and wing cases 

 golden brown. 



Staudinger's description of the larva and cocoon of E. caudata 

 Brem. agrees very closely with my description of those of E. 

 westwoodii, and this seems to prove that caudata is merely a 

 local form of westwoodii as mentioned by Jordan. Staudinger 

 also states that the larva and cocoon of caudata have a certain 

 resemblance to those of Aglaope infausta (sic= ? Agalope) . 



Imago. — I have noticed in Elcysma westwoodii that the tails 

 of the hind wings of the female are often shorter than those of 

 the male and that the forewings of the female are not so heavily 

 powdered with fuscous scales at the apex as in the male. My 

 Japanese collector informed me that this insect is very local and 

 only flies in the early morning, seldom afterwards. It seems to 

 be abundant locally, my collector having taken over a hundred 

 specimens. Pryer remarks: 



this flies by day and the first one I saw flying I took to be a new Parnassius, 

 it has long curled tails and is a very peculiar insect. 



The type of Agalope westwoodii was described by Vollenhoven 

 from a male captured in Japan by Doctor Siebold, not "from a 

 female found at Port May, Japan, August 15," as stated by 

 Staudinger.^^
