fewer antennal scgmonts. In Porath's s|)ccies, jiul<j^ing from 

 a number of oxamiiK'S sent to the British Museum from Cape 

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

 these ajipcndages is 30, but it varies from 26 to 35, whereas 

 in JI. tn'stani the number is 23 to 24 in four specimens.

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

 partly owing to the imperfection of the antennae of the type 

 specimen and partly to my ignorance of the North-American 

 sj)ecies of the geims. 1 cannot, however, match it with any 

 European species with which 1 am acquainted.
