Hab. N.W. Australia. 



Thorax with seven distinct areolets. The elytra parallel, with 

 the extreme apex dirty yellow ; the four costae on each elytron are 

 distinct, but the third is less so towards the apex ; the interstices 

 have rather closely placed irregular transverse ridges, which are 

 frequently oblique, or when half across the interstice divide into two, 

 forming a Y placed horizontally (>-), giving a reticulated appearance 

 to the elytra ; here and there the intermediate very fine longitudinal 

 costae may be traced.

Elytra about five times as long as the thorax, black at the apex ;
