Tribe Tetigoniini. 



In the Tetigoniini, the male genital segments are of simple 

 form. The last abdominal is probably the seventh. The pygo- 

 phor is sometimes not visible ventrally, being covered over by 

 the "Plates", which are not visible dorsally, except between 

 and below the pygophor ; apical of the 7th segment, there is dor- 

 sally a small semicircular plate, and ventrally a small triangular 

 plate, which is called the "Valve"; both these may be altogeth- 

 er absent and their absence or presence is proba'bly of generic 

 value ; for example, taking the careful figures in Ball's Mono- 

 graph of the North American Tetigoniini, I find that the valz'C 

 is present in Dracculaccphala and Helochara, absent in Dicdro- 

 ccphola, Tctigonia, Homalodisca, Aulacises, and Oncomctopia. I 

 am not sure that the Plates mav not be absent sometimes. 



in the females, the 7th segment is the last abdominal, the 

 8th is absent ventrally and only lateral margins can be seen, 

 basally at the sides, the 9th is divided and is generally shorter 

 than the ov'positor; the 7th is usually narrower than the pre- 

 ceding tergites and is very mobile, being lifted up from the 

 apex, at right angles, so that the ovipositor can have free play.

 There is no male valve in this genus (or if so, it is concealed).
