PAPILIO ALCINOUS Klug. 



This species is not represented in the Nawa tK)llection, l)ut the L'. S. 

 National Museum has it from the collection exhil)itcfl at C'hicago in 

 1898. which was presented by Professor Mitsukuri. 1 refer to it on 

 account of the peculiar larva, which is the most gen- 

 eralized of the three now referred to, namely, alcin- 

 oiis, de//ietrh(.s, and .rut/ms. It is allied to the Ameri- 

 can ph/lenor, and retains in the last stage the peculiar 

 hlack and white coloration, resembling bii-d excre- 

 ment, so characteristic of most all 3"oung Papilios. 

 The tubercles are produced into smooth papilla?, all 

 of about equal length, about three times as long as 

 wide at base.

The young larva resembles l)ird excrement. It is 

 lilaceous brown, with a white saddle and lateral shades 

 on thorax and abdominal segments 7 and 8. The tubercles show 

 rather prominently at the extremities and are pilose. There are 

 numerous small ))lack markings, of which subdorsal spots on second 

 and seventh abdominal segments are the largest. The shape is normal. 



The mature larva is largely green. Head oval, 

 rounded, brown. Meso- and meta-thorax enlarged, 

 swollen, smooth. Bright green; subdorsal ocellar 

 mark on metathorax oval, ])lack, with reddish central 

 dash, reddish ring and tine l)lack line. The pair are 

 joined across the dorsum l)y a series of eight spots in 

 two rows, black rings on a slightly yellowish field. 

 Subventral region of thorax purplish, the color reach- 

 ing up into the posterior metathoracic incisure to form 

 a band across; on anterior edge of tirst abdominal 

 segment a l)lack band. The purple color continues 

 along subventral region of abdomen and rises on the 

 fourth, sixth, and ninth segments in a white triangu- 

 lar blotch, from which a purple and white mottled 

 band runs ol)liquely backward on segments -i and 5, 

 joining dor.sally on 5 posteriorly; on segment 7 it rises more verti- 

 calh" and forms a subdorsal patch on the posterior edge of the 

 segment. Anal segment whitish and purple. The larva is smooth 

 without traces of tubercles.
