The following species, which iu pattern reminds one of Exigigas Thoms., is 

 different fi-om all the species of Xenocenis I know, in the structure of the head and 

 rostrum. The front of the head bears a very deep longitudinal groove which ends on 

 a level with the posterior margin of the eyes ; the borders of this groo\e are not 

 raised to keels; the mentum is very broad, flat, and gradually slojies off behind, and 

 bears, iu front of the transverse sulcus which sejiarates the rostrum fro7n the head, 

 just behind the sinus which borders the mentum hili rally, a short toolh-like process; 

 the mentum is very broadly emarginate.
