The proposed classification would therefore stand thus :- 



Family PAPILIONID^, Leach, 1819. 



Sub-Family II., PAPILIONIN^, Swainson, 1840. 



Tribe i. [The Median Nervure of the anterior wing with 3 branches.] 



Genera : i. Mesapia, Gray. Thibet ; ii. Calinaga, Moore, Sikkim ; iii. Styx, Staiidinger, Peru ; iv. Hypermnestra (?) 

 Men., Turkestan. 



Tribe 2. [The Median Nervure of the anterior wing with 4 branches ; the 2 with a waxy or corneus 

 secretion attached to the underside of the anat segment of the abdomen in all the genera but Doritis.] 



Genera: i. Doritis, Fab., Europe and Asia Minor; ii. Parnassius, Latr., Mountainous districts of Europe, N. 

 and Central Asia, Japan, and California, &c. ; and also in low and wooded districts ; iii. Eurycus, Boisd., Australia ; 

 iv. Euryades, Feld., Uruguay and Paraguay ; v. Lilhdorfia, Ersch, Japan (tailed in both sexes). 



Tribe 3. [Tailed in both sexes, median nervure of ant. wing ^-branched.] 



Genera: i. Serecinus, Westw., N. China; ii. Armandia, Blanch., Bhutan and Thibet (the 3 branches of the 

 median nervure of the posterior wing tailed, the first being the longest). 



Tribe 4. [The antennce strongly clubbed. Median vein as above] . 



Genera : i. Teinopalpus, Hope (the $ tailed in the usual manner of the tailed Papilios ; the 2 with a short tail from 

 the 2nd posterior median nervule, and a longer curved tail from the 2nd subcostal nervule) N. India; ii. Leptocircus, 

 Swainson, (with a very broad tail-like prolongation of the posterior wing) Indian region, Siam, Java, Celebes and 

 Philippines. 



Tribe 5. Troides, Hubner. [Median Nervure of ant. wing 4-branched; antennce stout, with the club or 

 apex more or less curved. 



Group I. The Acr^eoid Ornithoptera. 



Genus 1 : Drurya, Aurivillia. (The antenna? well clubbed), West Africa. 



Group II. The True Ornithoptera. 



Genus 2 : Schoenbergia, Pagenstecher. (The male of two sp. tailed.) New Guinea and Waigieu. 



[The anal valves of the $ are divided dorsally and subdorsally : the whole annulus being very distinct in 

 form from the other abdominal articulations and pointed at the terminal ; the valves would evidently 

 open wide in the act of coition, but the entire valve must be capable of considerable movement in a 

 downward direction at least ; the direction of the valve sutures is indicated by the triangulate black 

 mark, which decorates the annulus in all the genera, but most obtrusive in Schoenbergia and 

 ^Etheoptera, and the least in Pompeoptera.] 



Genus 3 : Ornithoptera, Boisd. The $ $ golden green and black with a pupaeform brand (the 2 2 brown and 

 white, grey, or yellow), N.W. Australia, N.S. Wales, New Guinea, and Molucca Islands. 



Section, Priamoptera. <7 $ violet, or orange red and black, 2 2 brown and white, or grey. New Britain, N. 

 Ireland and Solomon Islands, and Louisiade Islands. A green variety of the $ also occurs in New Britain. 



Genus 4 : JEtheoptera, Rippon. The $ $ Golden green, yellow and black, with a pupa? form stigma surrounded 

 by a slightly obscure opalescence, but often very intense in some examples ; the posterior wing strongly excised at the 

 anal angle ; the 2 2 brown, with white and yellow markings on both surfaces of the wings. Solomon Islands. 



Genus 5 : Trogonoptera, Rippon. [The $ with an abdominal marginal fold or pouch for the Androconia.] 

 Borneo, Sumatra, Labuan, and Philippines. 



Genus 6 : Pompeoptera, Rippon. [The $ with a similar abdominal marginal pouch : species of both sexes 

 generally black and yellow, except P. Doherty, Rippon, in which the sexes are nearly unicolourous on both surfaces — 

 the <? black (with a little yellow), the 2 brown.] In localities ranging from Ceylon, India and China to the Malay, 

 Philippine, Malacca, and other archipelagoes, N. Australia, and New Guinea.
