PYCNOPHILUS. 167 
1. Pycnophilus piceus, sp. n. (Tab. VII. fig. 4.) 
Piceus, parce griseo-squamosus, setis tenuibus erectis vestitus, elytris seriatim fortiter punctatis. 
Long. 57 millim. 
Hab. Costa Rica, Volcan de Irazu 6000 feet (Rogers). 
Rostrum finely canaliculate on the middle, squamose and setose, with the tip 
shining and elevated. Antenne red; second joint of funiculus as long as the first ; 
club abrupt. Thorax transverse, strongly rounded at the sides, obscurely rugose, 
squamose, and bearing erect sete. Hlytra broad at the base, but with the shoulders 
quite rounded ; somewhat convex, sparingly squamose, and bearing numerous erect, 
rather long, fine hairs, which, however, are not acuminate, and with distinct series of 
large punctures. Legs slender, setose; tarsi red. Under surface clothed with only a 
very few scales. One specimen. 
Group SCIAPHILINA. 
This group includes such of our apterous Otiorhynchide as have no ocular lobes, 
but have the claws connate and the scrobes lateral, descending rapidly at some distance 
in front of the eyes. All the genera have a small mentum, leaving the maxille 
exposed, slender antennze, and posterior tibie with delicate tips, the corbels being 
quite simple. There are numerous European forms very closely allied to those of 
our region; but the only North-American genus in Horn’s work that I can indicate as 
pretty certainly belonging to the group is Mitostylus, which he places in the Phyllo- 
biini. The Phyllobiina should, however, be: restricted to winged forms, with vague, 
superior scrobes. 
It is, nevertheless, highly probable that there are other North-American genera 
belonging to this group. I think it will be found to be the rule in the Otiorhynchide 
that when the mesosternal epimera are intermediate in size the species belong to the 
apterous series. Horn, however, appears to have referred most of the Otiorhynchidee 
with an intermediate form of epimera to his second division, which consists principally 
of winged forms. 
If these apterous forms were transferred from Horn’s Division II. to his Division I., 
they would be probably found to agree partly with the Sciaphilina as here treated, 
though some of them almost certainly belong to the Epicerina. The group ** Artipi ” 
seems to belong to the Epicerina (indeed, I feel little doubt from the description that 
some of the species of Aramigus and Phacepholis placed in it belong to the genus 
Pantomorus) ; while the ‘“‘ Aphrasti”’ may possibly prove to belong to a group not repre- 
sented in our region, but allied to the Cneorhini of the Old World. The group “ Omilei ” 
probably belongs to the Epicerina, as suggested by Horn; and Mitostylus of Horn’s 
group Phyllobiini I have already noticed as being probably near Sciaphilus. 
If these comparatively slight changes were made, the arrangement of the North-
