 thorax covered with blackish hairs which are darkest on the dorsulum 

 where they are shorter than the dark brownish hairs on the meso-

 punctures from nearly adjoining to six puncture widths apart, 

 the punctures mostly sparsely distributed, notauli represented by 

 an impressed shining line, mesopleurae sculptured much like the
