26 Mr. C. J. Galian on Longicorn Coleoptera 



Antenuae nearly twice as long as the body, 

 with the third and fuiirth joints scarcely 

 thickened at the apex, the third much longer 

 than the fourth. Prothorax very slightly 

 rounded at the sides. Elytra with slight 

 moire reflexions. Apices somewhat obliquely 

 truncate, eacli briefly spiuose at the suture. 

 Intermediate cot^'loid cavities narrowly open 

 externallv 8. P. natalensis, White. 



rarhi/rlissKs elongatus, Harold, may perhaps come into this section. 

 According to Harold it is very near P. natalensis, and diiTers chiefly by 

 its sHghtly curved posterior tibia3. The third joint of the anteniife is 

 scarcely longer than the first, while in P. natalensis the third joint is 

 nearly twice as long as the first. 



§ B. Antennae ( c? ) longer than the body, with 

 the third and fourth joints more or less 

 thickened, the third scarcely longer than 

 the fourth. Elytra rounded or subtrun- 

 cate, and unarmed at the apex. Femora 

 without carinas. Presternum simple, not 

 very stronjily arched. Head without a 

 distinct transverse groove underneath. 

 {Mai-ffites, Pasc, MS.) 



Antennfe with the third and fourth joints 

 strongly thickened, obconical. Prothorax 

 slightly uneven at the sides. Elytra with a 

 grey pubescence 9. P. egenus, Pasc. 



Antennae (c?)? Prothorax somewhat un- 

 even At the sides. Elytra with a ftdvous 

 pubescence 10. P. fuhidus, Pasc. 



Antennae a little longer than the body, with 

 the first to hfth joints subequal, the third and 

 fourtli thickened, subcylindrical. Prothorax 

 evenly and not very strongly rounded at the 

 sides. Elytra with a greyish tawny or fawn 

 pubescence 11. P. humilis, sp. n. 



§ C. Eyes large, not verj' widely separated 

 below. Antennae in the male longer than 

 the body, with the third and fourth 

 joints siightly thickened at the apex, 

 the third distinctly longer than the 

 fourth. Apices of the elytra truncate 

 or subtruncate, dentate or unarmed. 

 Femora feebly carinate on each side 

 below. Prosternal process not strong^ly 

 raised, subtruncate or tuberculate near 

 its posterior extremity. Metasternum 

 usually provided with a small antero- 

 lateral process, which partly cuts off 

 the epimeron from the intermediate 

 cotyloid caviiy. (iJerolus.) 



Antennae about half a? lung again as the
