Paussoceros n. g. (Textfig. 4.) 



Allied to the genera Paussoptinus Lea and Leaptinus 

 Mjöb. n. g. but differing in form and shape of the antennse. 



Antennse very flat and laterally compressed, 9-jointed. 

 A reduction of the distal joints has taken place, the apical joint 

 being very small and received in the eighth, the joints 3 — 8 

 very broad and flat, the first and second being less modified. 



The genus represents a new and interesting stage of re- 

 duction and very likely a similar one to that which the genus 

 Ectrephes has undergone. The similarity with an Ectrephes is 

 striking, both having the apical joint more or less rudimentary 

 and received in the next last ones.

6. Paussoceros anteimalis n. sp. (Textfig. 4.) 



Castaneous, shiny, head, prothorax and legs somewhat 

 darker; head with an indistinct median line; antennse enorm- 

 ally developed; very broad, shiny, the basal joint strongly 

 developed, bent in the shape of a knee; the second joint much 

 shorter but much broader, the other joints, from the third 

 to the very small and rudimentary ninth, forming a sort of 

 flat broad club, eacli of these joints with a strong trans- 

 versal impression, and slightly bisinuate at the base, the eighth 

 at the top very sinuate, entirely receiving the small last
