This interesting insect seems to connect the two subgenera in 
this genus, described in my monograph upon the group in the 
second volume of the “ Transactions of the Entomological Society 
of London,” possessing the apparently 3-articulate antennee and 
simply setose tibize of Holoptilus, and the maculated and venose 
hemelytra of Ptilocnemis. The hind feet are much shorter and 
less densely setose even than in H, ursus, but the crown of the 
head and the base of the hemelytra are very thickly lanose or 
setose.
