68 MR. A. R. WALLACE ON THE PAPILIONID.* 



Local form e. Broader and less sinuated wings, body large, tail very short. 



Hah. Ceram, Bouru, Batchian [Wall). 



Local formy. Form of c; tail reduced to a tooth; markings and spots well defined, 

 rounded. 



Hah. New Guinea, Aru Islands, Waigiou [Wall). 



119. Papilio Rama, Felder. 



P. Rama, Feld. Lep. Nov, Mai. p. 1. P. Arycles, Bois'd. Sp. Geft. Lep. p. 231 ? 

 Hab. Malacca, Sumatra (Wall.). 



Remarks. — I have little doubt but this is the P. Arycles of Boisduval. His descrip- 

 tion, hoAvever, does not mention the distinctive character of the four large spots only 

 in the discoidal cell ; I have therefore used Dr. Felder's name. 



Leptocikcus, Swainson. 



This small but interesting genus differs somewhat from Papilio in the neuration of 

 the wings, but is best distinguished by the longitudinal fold and great elongation of the 

 hind wings. The species frequent water, often settling on the edges of rills, or hovering 

 over pools and rivulets in the sunshine. The few species known are all veiy closely 

 allied, and might with equal propriety have been considered as local forms of one 

 species. Three have been ah'eady described, and I have therefore thought it better to 

 add one more, than to attempt to reduce those which have been generally accepted as 

 species to a lower rank.

Sp. Gen. pi. 7. f. 1, pi. 17. f. 3, p. 381. 

 Hab. Java, Malacca [Wall.). 



121. Leptocircus Curtius, n. s. 



Larger than L. Meges ; outer black margin broader, and apical nervures thicker ; bluish 

 band much naiTOwer, of equal width on both wings, straight, abruptly narrow where it 

 crosses the discoidal ceU of the fore wings, and rounded at the inner margin so as to form 

 a small notch at the junction of the fore and hind wings. 



Under side with the band bluish silvery ; the three small bands on the anal margin 

 differing from those on Jj. Curius and L. Meges, the first being transverse, and not pro- 

 duced obliquely to join the vertical band, the second small and nearly ol)solete, the third 

 at the anal angle transverse, very little curved, and sharply defined. 



Body beneath and base of all the wings greenish ashy. Expanse of wings 1t^2 inches. 

 Length, head to tip of taU 2^ inches. 



Hab. Celebes (Wall).
