Mas. Vertice capitis subtilissime pubescente, elytrorum inter- 
stitiis 1, 3, 5, 7 non declivibus, carinatis, nitidis, in spinulas liberas 
circum declivitatem productis; spinulis et declivitate glabris.

Head in both sexes dull, with close reticulation; front in male 
impressed to eyes, concave, vertex, which forms an angle with front, 
and is hidden when head is extended, more strongly punctured, 
feebly pubescent; front in female convex, glabrous, except for a 
fringe over mouth, impressed above mouth, and with a fine central 
suture. Antennal hairs of male not very long, except at tip of club, 
simple; pores of club small, not close. Thorax with base strongly 
bisinuate, produced in middle, its basal angles produced, and 
pointing slightly forwards; anterior angles of emargination less 
prominent than in next species, and lateral border gradually 
rounded anteriorly and not angulate, apical emargination in male 
inconspicuous, surface quite dull, with a fine median impressed 
line, not extending in front of pore in female, closely covered with 
shallow, somewhat variolose punctures, which are smaller in the 
female. Elytra with base slightly bisinuate, its margin raised and 
acute, humeral prominence small, obtuse; stris impressed, with 
irregular coalesced punctures, the first two obsolete at base, inter- 
stices finely reticulate, somewhat shining at base, with fine irregular 
punctures, which become stronger and more rugose towards apex ; 
alternate interstices carinate in male from before middle of elytra 
the carine smooth on the summit throughout, ending in short free 
spines with but the barest trace of any hairs, towards the apex the 
2nd interstice is faintly impressed and narrowed; interstices in 
female similar throughout. 
Under side black, with apex of elytra lighter, sparsely pubescent, 
punctured, coarsely on base of prosternum and abdomen; meta- 
sternum flattened in front with a fine longitudinal carina. Male 
with a long wisp of hair on anterior coxe; abdomen with apical 
segments flatter than in female, last segment hairy. Anterior legs 
of male somewhat stout, junction of trochanter and femur angu: 
lated below, femoral lamella distinct. Prothoracic fover of male
