THAITES. 57 



PAPILIONID M PAP1LIONIDES - PARNASSII. 



THAITES HEBR, MS. 



Body rather robust (PI. Til, figs. 9 and 10). Vertex of head large, broad, 

 convex. Eyes pretty large, short ovate, their longer diameter vertical. Palpi (PI. 

 Ill, fig. 7) slender, resembling those of Thais, but rather longer, extending far 

 beyond the eye, rather thinly clothed with hairs. Antennae (PI. Ill, fig. 8) resem- 

 bling those of Sericinus more than those of Thais, being about half as long as the 



body, slender and equal on the basal three-fifths, gradually expanding beyond into 





 a club, which is more than twice as broad as the stem, and stoutest just before the 



well rounded, slightly upturned tip; in the middle of the antenna? the joints are 

 half as long again as broad, broader than long at the base of the club, and three 

 or four times as broad as long in the middle of the club and beyond ; on the apical 

 half of the club, and perhaps a little further, the joints of the club are furnished 

 with a double row of minute shallow pits, such as are seen in Eurymus. The 

 tongue was at least as long as the thorax. 



The thorax is well arched and pretty stout; the paraptera (PI. Ill, fig. 6) are 

 a little more than twice as long as broad, their outer edge nearly straight, the pos- 

 terior extremity broad and well rounded. The legs are not well enough preserved 

 to state anything concerning them with certainty, but the middle (?) pair are 

 probably of the length of the antennae. 



The fore wings (PI. Ill, fig. 3) are only a little more than half as long again 

 as broad, the greatest breadth beyond the middle; the costal border is pretty regu- 

 larly and nqt greatly arched throughout; the outer margin is more strongly arched 

 but with a similar regularity, and the general direction of its upper half is at right 

 angles to the outer third of the costal border, the apex scarcely rounded off; the 

 inner border is nearly straight. The proportions of the hind wing, as to length 

 and breadth, are nearly the same as those of the fore wings, making it unusually 

 long and narrow, as in Thais (PI. Ill, fig. 4), and also, as there, nearly as broad 

 toward the base as at tip. The costal border is rather strongly convex next the 

 base of the wing, but beyond is nearly straight, sloping apically so as to make a
