67 This species is remarkable for possessing two ocelli : but the structure of the ab- 

 domen proves it to belong to the Oxytelini, and in no part of the body does it show 

 any difference from Trogophloeus : it and the preceding species belong to the division 

 possessing a visible scutelluni.
