I have retained for this species the manuscript name it bears

AxiNOTOMA POSTICALIS. 



Black, subopaque, with the labrum, palpi, antenna3, legs, and 

 a very broad lateral border on the prothorax and an apical patch 

 on the elytra fiavescent ; prothorax as in the preceding species but 

 slightly less constricted laterally behind ; elytra oblong, slightly 

 broader than the prothorax at base, striate, intervals plane, closely 

 aciculate, the apical fiavescent patch is triangular, and extends 

 as far as the third stria on each side ; the ultimate joints of the 

 palpi are not so swollen as in A. obtuseangula and are smooth 

 instead of being briefly bristly ; the puncture on the third interval 

 is similar. Length lOf mm. ; width 4 mm.
