23 Mr. C. J. Gahan on Longicorn Gohopfera 



Antennae nearly twice as Long as the body, 

 ■with the third and fourth joints scarcely 

 thickened at the apex, the third much longer 

 than the fourth. Prothorax very slightly 

 roiiuded at the sides. Elytra with slight 

 moire reflexions. Apices somewhat obliquely 

 truncate, each briefly spiuose at the suture. 

 Intermediate cotyloid cavities narrowly open 

 externally 8. P. natalensis, White. 



Pachydissus elongates, Harold, may perhaps come into this section. 

 According to Harold it is very near P. natahnsis, and differs chiefly by 

 its slight^ curved posterior tibia?. The third joint of the antennae is 

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

 nearly twice as long as the first. 



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

 the third and fourth joints more or less 

 thickened, the third scarcely longer than 

 the fourth. Elytra rounded or siibtrun- 

 cate, and unarmed at the apex. Femora 

 without carina?. Presternum simple, not 

 very strongly arched. Head without a 

 distinct transverse groove underneath. 

 (Margites, Pasc, MS.) 



Antenna? with the third and fourth joints 

 strongly thickened, obconical. Prothorax 

 slightly uneven at the sides. Elytra with a 

 grey pubescence 9. P. ege.nus, Pasc. 



Antenna? ( rf ) P Prothorax somewhat un- 

 even at the sides. Elytra with a fulvous 

 pubescence 10. P. fuhidus, Pasc. 



Antenna? a little longer than the body, with 

 the first to fifth joints subequal, the third and 

 fourth 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 very widely separated 

 below. Antenna? in the male longer than 

 the body, with the third and fourth 

 joints slightly thickened at the apex, 

 the third distinctly longer than the 

 fourth. Apices of the elytra truncate 

 or Bubtruncate, dentate or unarmed. 

 femora feebly carinate on each side 

 below. Prosternal process nol strongly 

 raised, subtruncate or tuberculate near 

 its posterior extremity. Metasternum 

 usually provided v\itli a small antero- 

 lateral process, which partly cuts off 

 tin' epimeron from the intermediate 

 cotyloid cavity. [Derolits.) 



Antennae about half as long again as the
