Type.—Papilio lycidas Smith-Abb, 



Let me smell the wild white rose, 

 Smell the woodliine and the may; 

 Mark, upon a sunny day, 

 Sated from their hlossoms rise, 

 Honey-bees and butterflies.

(57:1). Head very large, clothed with moderately short hairs, arranged 

 in transverse, somewhat appressed ridges, the most conspicuous one connecting the 

 antennal bases; a very short, thick, appressed, nearly straight bunch of bristly hairs 

 projects a little way beyond the rest at the exterior base of the antennae, directed out- 

 wards; front considerably and almost uniformly tumid, surpassing somewhat the 

 front of the eyes ; the corners are largely rounded off, the front border straight and 

 emarginate; the hind border between the middle of the antennae straight and scarcely 

 sulcated ; less than twice as broad as long. Vertex nearly flat, very slightly and 

 gently tumid, almost equalling the height of the eyes, longer than the front, separated 

 from the occiput by a deep, brace-lilie, scarcely impressed line. Eyes large, full, very 

 nearly round, naked. Antennae inserted with the hinder edge in the middle of the 

 stimmit, in slight pits, their interior bases separated from each other by a little less 

 than twice the diameter of the antennal base; exclusive of the crook about one-third 

 longer than the abdomen, composed of 49 joints of which 2G form the cylindrical club, 

 which is about half as long as the stalk and bent somewhat beyond the middle at 

 about the 34th joint; the club increases very gradually in size at first with scarcely 

 any diminution in the length of the joints, is longest from the 27-31st joints and is 

 nearly as broad as the length of two joints, diminishes in size very gradually, but 

 a little more rapidly in the apical half of the attenuated portion and ends in a blunt 

 tip, about three-fourths the diameter of the stalk and scarcely broader than the length 

 of the joints ; in the middle of the stalk the joints are a little more than three times 

 as long as broad and the crook is strongly recurved at less tlian a right angle. Palpi 

 very short and very stout, a very little longer than the eye, heavily clothed with long 

 and erect, elongate scales, beyond which only the tip of the apical joint, clothed with 

 recumbent scales only, projects ; the basal joint is globose, the tiunid projection of 

 the anterior inner portion of the apex giving it a subpyrif orm appearance ; the middle 

 joint is tumid, cylindrical, obovate, straight, two and one-half times longer than 

 broad, the ends similar, tlie apical joint minute, ovate, nearly half as long again as 

 broad and its length contained about two and one-half times in the breadth of the 

 middle joint, directed forwards. 



Prothoracic lobes closely resembling those of Eudamus, nearly as long as the shorter 

 diameter of the eye. Patagia large, well rounded, the posterior lobe long but not 

 slender, more than half as broad as the base, scarcely three times as long as broad, the 

 basal half equal, the apical half tapering a little, the tip very bluntly pointed, the 

 whole piece nearly as long as the breadth of the head. 



Fore wing (41 : 5) triangular, much less elongated than in the preceding genera, 

 being but little more than half as long again as broad; costal margin gently arcuate, 

 but flattened along the middle ; the outer margin moderately arcuate in its upper half, 

 below nearly straight ; the upper third bent at scarcely less than a right angle with 

 the outer half of the costal margin ; the outer margin is not produced at the snbmedian 

 nervure; the anal angle is well rounded and the inner margin barely concave, and of 



*o- x'^'i'PoS' o'le by no means languid.
