ERYCINID^. 



Genus XX. PANDEMOS. 



Pandemos Hiibner. 



Pandemos, Theope p., EuRYGONA p., E. Douhleday. 



Erycina p. God'. 



Body elongate: wings large, uniformly and plainly coloured, especially beneath. 

 Head small, finely hairy, scarcely tufted. 

 Exi€s nalvGcl. 

 Antennce short, scarcely more than half the length of the fore wings, very slender ; articulations indistinct, not 



rino-ed with white ; terminated by a large, gradually formed, but slender club, pointed at the tip. 

 Labial Palpi very scaly, porrected obliquely ; the tip considerably in front of the hairs of the head, and elevated 

 to the middle of the eyes ; terminal joint slender, more or less conical, subhorizontal. 



Thorax moderate-sized, scaly. . , , , ^ a • i 



Fore Wings large, elono-ate-triangular. Costal margin nearly straight ; apical angle subacute. Apical margin 

 sli"-htly convex, entire, three fourths of the length of the costal. Inner margin nearly straight, of equal length 

 with the apical ; veins arranged nearly as in Theope. The postcostal vein rather wide from the costa ; second 

 and third branches of the postcostal free, arising before the anterior extremity of the discoidal cell. Upper 

 disco-cellular almost obsolete, extremely sliort, but oblique ; middle and lower ones very slender, much longer, 

 of nearly equal length, transverse, closing the discoidal cell transversely about the middle of the ^ylng. Upper 

 discoidal arising at the junction of the upper and middle disco-cellulars ; the lower disco- cellular uniting with the 

 median vein close to the origin of its third branch. 



Hind Wings variable in shape, oval or subtrigonate. Costal margin arched, outer margin entire, i recostal vein 

 oblique. Costal vein extending to about two thirds of the length of the costa. Postcostal branching at a con- 

 siderable distance from the base. Upper and lower disco-cellulars very slender, transverse, of nearly equal 

 leno-th ; the former arising close beyond the branch of the postcostal vein, and the latter uniting with the 

 median close to the origin of its third branch. 



Fore Legs of the male very small, slender, and not very thickly hairy. Fore Legs of the female much more 

 elongated, scaly. Tibia3 and tarsi with short spines beneath. 



Four Hind Legs slender, scaly, slightly spined beneath. Tarsi elongated. 

 Abdomen elongated. 



The 

 fore 



the hind wings bear a large black spot in the middle of the costa, followed by a white one ; beneath the colouring is still more smiple ; 

 the fore wim^s being dirty brownish white, with similar markings ; and the hind ones bluish white, unspotted. I have added to this 

 genus Papilio Lagul, although differing in the more triangular form of all the wings, and the rich purple gloss with which they are 

 almost entirely suffused on the upper side : in the arrangement of the wing veins, however, and the plain colouring of their under 

 surface, it does not materially difl'er from P. Areas. For the same reason, the undescribed species named by Mr. E. Doubleday 

 Eurygona ? Cydon must also be added to the genus. 



The beautiful species represented in our Plate LXX. f. 5. differs from all the preceding in its bright sulphur colour, and the slender 

 golden line running close to the outer margin of all the wings.
