A paratypic series of one male and two females, taken in June and 

 September, have also been examined. Aside from the fact that the

Tf/jje. — T. hergi Brunner. 



This very peculiar genus is considered by Brunner to be related to 

 Stauronotus (Dociostfturus), but the general appearance and structure 

 is so different and with so many peculiarities that the type is probably 

 worth}' of separation as a group Tristtri. This genus in many respects 

 resembles Closteridea Scudder/' from Chatham Island, Galapagos, and 

 it is quite likely they are closel}' related.
