duced outwardly and rounded, eighth minute, lenticular, ninth to 

 tenth large, lenticular, eleventh truncate at base, short, obtuse at 

 tip, depressed, transversely excavate inwardly, and incised laterally 

 also inwardly. 



Female : Broader behind ; seventh joint of antennae a little larger 

 than the others, subquadrate, eighth minute, transverse, ninth to 

 tenth large, transverse, eleventh briefly ovate and obtuse at tip. 

 Length 2-70-3 mm. 



Hab. Cape Colony ; somewhat common in Cape Town and 

 neighbourhood — Newlands, Constantia. 



PSELAPHOCERUS DIVERSUS, 



Plate XVIL, fig. 11. 



Nearly similar to the preceding species ; the colour is more 

 uniform and generally darker. 



Male : Seventh joint of antenme large, irregularly trapezoidal, 

 hardly produced outwardly and rounded for a short space, eighth 

 minute, transverse, ninth and tenth large, transverse, eleventh ovate, 

 truncate at base, obtusely acuminate at tip, obliquely and broadly 

 excavate inwardly, and with an ante-apical and squamose, longitudinal 

 irregular carinule. 



Female : Seventh joint of antenna? hardly broader than the pre- 

 ceding one, but nearly twice as long, eighth a little smaller than the 

 sixth, and more transverse, ninth to tenth large, slightly transverse, 

 eleventh ovate, obtusely acuminate ; size of the male. 



In both sexes the eighth, ninth, and tenth joints of the antennae 

 are much less transverse than in the male of P. peringueyi, the 

 seventh is somewhat quadrate, whilst in peringueyi it has a trian- 

 gular shape, the last one is neither so short or so broad, and the 

 sculpture of the under part is quite different ; in the female the 

 seventh joint is longer but not broader, whilst in peringueyi it is 

 broader and nearly quadrate, the eighth, ninth, and tenth are much 

 less transverse, and the last one regularly ovate. 



This species is much rarer than the preceding one. I have found 

 only a few specimens near Cape Town on the Kloof Eoad, on the 

 Camp's Bay side.
