c? ? . Tenth abdorniiiiil segment niesially divided, often asymmetrical, the left 

 half of the tergite and sternite, or the right half of the sternite, being sometimes 

 rednced, vestigial, or even absent ; right and left claspers occasionally also nnequal; 

 no large friction-scales. The lower genera with iiniscrial abdominal s]>ines, at least 

 on the last segments, the spines all long, or long ones alternating with small ones. 

 The seventh sternite of the ? trapeziform, or sinnate, often spiuose at the apical 

 edge, sometimes only laterally ; if the sternite is small and triangular, and the 

 spination of the tergites mnltiseriiil, the mesonotnm is prominently crested or the 

 palpns angnlate laterally. 



One hundred and thirty-three species belonging to twenty-four genera. One 

 genus is Holarctic {Hatunorrhagia), extending into the Oriental Region ; one is 

 Oriental {Sataspes), and one Aethiopian and Oriental (Cejj/tonodes) ; all the others 

 are American. 



Two tribes, Dilophonoticae and Sesiicne. 



Key to the genera :

 those of [)roximal row of tergites 

 broader than long ...... v.

 all long, or long and short ones 

 alternating . . . . . . . b.. 



h. Basal sternite of abdomen with strong 



spines ...... XOIII. Onjha. 



Basal sternite of abdomen with few 



weak spines, or not spinose . . . . c.
