Insects of larger size than those of the preceding genera, remarkable by their fine 

 metallic colours, and by their mimetic forms, imitating Coleopiera, especially the 

 Cicindelidse and Chrysomelidse. In this genus the right elytron, which in rest covers 

 the back, is coriaceous and colouied so as to imitate the fades of Coleoptera. The 

 left elytron remains in great part membranaceous and hyaline ; the musical instrument 

 has been here partly lost, to enable the insect to become mimetic. Nevertheless, the 



* This figure is not quite correct : the inferior little vein of the lateral field of the elytron (the fourth) 

 has been omitted; it is confluent with the base of the third vein and forms thus a small cell.
