specimen, collected in December, by Mr. H. G. Hubbard. 
The palpi are rather short, with the last joint ovate-pointed 
as in the preceding, but it differs from that, as from all the 
others in our fauna, by the foveze of the head being much 
nearer the eyes. The eyes are more lateral and prominent, 
and have not a shallow groove and elevated margin above 
them. This margin, though not strongly marked, is seen 
in the other species, and separates the upper sib. of the 
cranium from the sides.
