striées, ponctuées», whilst in fucf the sculpture consists of sharp 

 ridges. Also having now more specimens of my var. diluiipes, I 

 have raised it to the rank of a distinct species. Finally no one 

 will wonder, I suppose, that an arrangement made for six species 

 proves to be quite inapplicable for nineteen species.

Generic Characteristics and Classification. 



I have made already allusion to the excellent explanation of the 

 generic characteristics in Prof. Lacordaire's classical work, however, 

 as his description is taken from a single species, some of the 

 characters are too restricted and ought to become somewhat more 

 extensive, in order to be not in contradiction with specific diffe- 

 rences, which a so much larger number of species necessarily 



afford.
