specific character. In this matter I follow Blanchard, as I 

 find the 8-jointed species, almost without exception, of such 

 uniform appearance and so different from the 9-jointed ones, that 

 I think they might well be placed in a separate genus. Burmeister 

 on the other hand, makes his subdivision of the genus depend 

 chiefly on what seems to be an unimportant character — the relative 

 length of the 1st and 2nd joints of the posterior tarsi. In 

 determining the species, I look upon this character as useful, 

 but as the character of a group it is bad, as it separates species 

 evidently closely related. But others of Burmeister's sub-divisions 

 founded on the form of the clypeus in the male are undoubtedly 

 good, and these, with some modifications and additions, I have 

 adopted in this paper under the title of Sub-sections. 



Further sub-divisions of these sub-sections are founded on the 

 variations in the clothing of the species as " villose, glabrous, 

 scabrous, velvety, sericeous," &c. Other anatomical points, some 

 of them sexual, might be enumerated as valuable for identification, 

 but these I think will be readily ascertained by attention to the 

 descriptions. I propose then to group all the species of the genua 

 as follows : —
