 the head and the association of the males with the females, however, 

 made the identitieation (][uite certain.

 third; nintli segment with the posterior margin concave, exposing the 

 tip of the triangular supraanal plate. Cerci shaped as in femorata 

 and vellei., with the basal tooth intermediate between those species. 

 Legs long and slender, the middle femora relatived; h'ss swoll(>n than 

 in allied species.

This species is closely allied to femorata and veliei, but can be dis- 

 tinguished from them by the characters given in the table and by the 

 more slender form. The elongate seventh abdominal segment will 

 readily separate it from vellei. It is quite a characteristic-looking 

 species, though the differences that separate it from its allies are diffi- 

 cult to deiine.

 rupted at the posterior end of the mesonotuui, the fore legs greenish, the antenna^ 

 testaceous; thorax with excessively fine transverse striation. Mesothorax and meta- 

 thorax (including median segment) of similar length. Seventh and eight li abdom- 

 inal segments of subequal length, each faintly enlarging from base, the ninth a httle 

 shorter, apically inflated and subglobose, nearly half as broad again at apex as a 

 base, the cerci much as in 7^. femorata, but stouter, more compressed, and without 



basal tooth. . ., , .
