typical; thorax covered with an abundance of whitish hairs which are as long 
on the dorsulum as the whitish hairs on the mesopleura, dorsulum dullish, 
finely reticulated and punctured, the punctures nearly hidden by the hairs, 
from one to two puncture widths apart, notauli represented by a shiny line, 
anterior aspect of mesopleura with blackish hairs like the mesosternum, sculp- 
tured somewhat like the dorsulum but not so closely punctured, mesopleura 
not hidden by the sparse hairs, scutel hairy and sculptured much like the
