PAPILIONIXAE: TIIH GENUS LAKllTIAS. 1231 



of the iippiM- margin nf tlie cell, secDiiil at less than oiie-tliirdthe distance from that to 

 the ni>ex of the cell, the third at the apex and the fourth at one-thinl the distance 

 from that to the outer niarijin ; cell somewhat more tliaii half as lon<; as tlie winii, three 

 ami a half times loujjer than broad ; at the origin of the fourth median branch the 

 main vein is raised above the continuation of its tiasal half by two-thirds the width of 

 the last median interspace at its base; cross vein connecting median with submedian 

 near the base directed strai;;ht downward. 



Hind wings with the costal border considerably and roundly expanded next the base, 

 beyond either slightly convex (<J) or nearly straight ($),well rounded otl' in both 

 sexes to the strongly crenulate hind border which is well rounded, but much more 

 produced in the lover half in the $ , and |)roportionally fuller in the subcostal region 

 in the $ , the median portion of the t)order being, in l)oth sexes, at an angle of about 

 110° with the subcostal; the upper median nervule is produced into a long equal 

 tail live or six times as long as broad, its tip tapering to a rounded point; just 

 beyond the tip of the lowest median nervule the border rounds olT and recedes 

 abruptly to more than the width of an interspace, at the same time approaching some- 

 what the nervule and then continues on a course at a slight angle with that of the 

 lower half of the wing, the angle well rounded; inner border a little folded, slightly 

 concave. Subcostal nervure nearly straight between the bases of the first and second 

 nervules : vein closing the cell slightly longer than the space between the bases of the 

 second and third median nervules. 



Fore femora and tarsi of equal lengtli and nearly h.alf as long again as the fore tibiae ; 

 middle tibiae as long ( ^) or five-sixths as long($) as the femora, the tarsi some- 

 what longer; hind femora shorter than the tibiae and tliese than the tarsi, which are a 

 third longer than the femora; femora of nearly equal length, the middle pair longest, 

 the hinder shortest; middle and hind tibiae of equal length and about half as long 

 again as the fore tibiae ; hind pair of tarsi somewhat longer than the middle pair and 

 more than a third longer than the fore tarsi. Tibiae furnished with four rows of 

 rather long and very slender spines, one on either side below and one on either side 

 above, all directed forward, but those in the upper rows horizontally, the others spread 

 at an angle outward ; besides these, there are, espechally near the ti)), a few other smaller 

 spines, irregularly disposed, and on the inner side of the tip beneath a single long and 

 very slender spur, surrounded by a few stoutish spines. First joint of tarsi equal to 

 the three succeeding taken together, these scarcely diminishing in size in regular se- 

 quence, the fifth equal to the second, all furnished beneath on either side with a row 

 of fre(iuent. very small and slender spines, those of the inner side not spreading 

 laterally ; and at the tip of e.ach joint a much longer and very slender spur, and three 

 or four supplementary ones at nearly equal distances on the basal joint; on either side 

 above, two rows of frequent, minute, nearly recumbent spines; claws long and very 

 slender, a little compressed, the under edge straight, the upper very slightly curved, 

 the tip llnely pointed and scarcely curved : paronychia and puvilli wanting. Hook of 

 eighth abdominal segment of in.ale rather slender at the base, the tip bluntly pointed ; 

 valves very short, tumid at base, right angled at tip, of about equal length and 

 breadth, slightly armed within at the extreme base. 



Egg. Nearly globidar, with base slightly flattened, leaving the height and width 

 equal; surface granulated, covered with minute, irregular globules of oily looking 

 matter. 



Caterpillar at birth. Head smooth, well rounded, tineiform, twice as broad as 

 long or deep. Body nearly cylindrical, a little angulated along the line of the upper 

 row of tubercles, perh.aps largest on the first thoracic segment, which bears a superior 

 shield, the posterior half of the body smaller than tlie anterior half. There are 

 laterodorsal, infralateral. suprastigmatal, infrastigmatal and ventrostigmatal rows of 

 large, subconical tubercles, one to a segment in each row, each of those above the 

 spiracles bearing, at least on the abdominal segments, a single long, straight, non- 

 tapering bristle, those below and some thoracic ones above bearing a sliglit whorl of 

 shorter bat similar bristles; the infralateral tubercles are situated mesially on each
