126 Mr. R I. Pocock on the 



i'iiwei- antennal segments. Tn Porath's species, judging from 

 a number of examples sent to the British Museum from Cajjc 

 'J'own and Port Elizabeth, the usual number of segments to 

 these appendages is 30, but it varies from 26 to 35, wiiereaa 

 in II. tristani the number is 23 to 24 in four specimens.

 teeth. 



Tergites at the posterior end of the body lightly rugose ; 

 the posterior angles of 9, 11, and 13 strongly dentate. 



Coxal pores rounded, in a single series, 4, 5, 5, 4. 



A7ial legs long but moderately thick, armed beneath with 

 1, 3, 2, 1 spurs ; claw spurred.

I am rather doubtful as to the distinctness of this species, 

 partly owing to the imperfection of the antennaj of the type 

 specimen and partly to my ignorance of the North- American 

 species of the genus. I cannot, however, match it with any 

 European species with which 1 am acquainted.
