Hab. Malacca, Sumatra (Wall.). 
Remarks.—I have little doubt but this is the P. Arycles of Boisduval. His descrip- 
tion, however, does not mention the distinctive character of the four large spots only | 
in the discoidal cell; I have therefore used Dr. Felder's name. 
LEPTOCIRCUS, 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 very closely 
allied, and might with equal propriety have been considered as local forms of one — 
species. "Three have been already 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. | 
120. LEPTOCIRCUS MEGES, Zinken. 
P. Meges, Zink. Beitr. Ins. Java, p. 161, tab. 15. f. 8.  Leptocircus Curius, Sw. Zool. Ill. pl. 106; Boisd.

Hab. Java, Malacca (Wall.). 
121. LEPTOCIRCUS CURTIUS, n. s. 
Larger than L. Meges ; outer black margin broader, and apical nervures thicker; bluish 
band much narrower, of equal width on both wings, straight, abruptly narrow where it 
crosses the discoidal cell 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 margit à 
differing from those on L. Curius and L. Meges, the first being transverse, and not pro 
duced obliquely to join the vertieal band, the second small and nearly obsolete, 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 1155-2 inches 
Length, head to tip of tail 24$; inches. | 
Hab. Celebes (Wall.).
