 synopsis of our species : — 



A. Clypeus truncated at the apex. 



1. Body yellowish-brown without any red on abdomen and legs. 



nassata. 



2. Body black with red on abdomen and legs. 



Apex of abdomen red (rarely black), calcaria long, male with 

 abdomen red from the 2d segment; hind tibiae and femora 

 black. dimidiata. 



Abdomen with a broad red band in the middle; calcaria short. 

 Male with the last abdominal segment not emarginated. 



scutellaris. 



B. Clypeus with the apex incised, pleurae somewhat punctured; 



abdomen with the 2d to 7th segment red. excisa.
