Faust has also included in the Phyllojjiides the purely Indian 

 genus Brachyxysfus, Fst. (Dent. Eat. Zeit. 1897, p. 355), but in 

 the classification here adopted it cannot be retained in this group 

 on account of the very different structure of the mouth-parts, 

 for the submentum lias a distinct peduncle and the maxillae and 

 their palpi are fully exposed, while the inaiidibles show no trace 

 of a scar. It must, therefore, be transferred to the Pha:s'e- 

 ROG>^Viiii, being nearly rehated to Canono/)sis, Wtrh., of the group 

 EcTEMyoKiuiiNinES, all the other members of which are wingless 

 and confined to Kerguelen or other islands in the Southern 

 Ocean.
