and the other much longer on the posterior part of the 
elytron. The antennee are of a shining black, or pitchy- 
black throughout, fringed beneath with longish hairs in 
their basal part, and rather more densely clothed with 
hairs in their apical portion. The elytra are naked and 
glossy, except near the base, where there are numerous 
very long, gray, erect hairs. The body beneath is very 
glossy, except the sides of the meso- and meta-sternum, 
which are finely tomentose. The elytra are rather 
thickly punctured throughout.

I do not know on what grounds Mr. White placed this 
species in the genus Obrium, to which it bears very little 
resemblance. All the characters are those of the typical 
Hesperophanes, with the exception that the head is more 
exserted, with a more convex neck, and the thorax more 
elongate. The thorax is, however, essentially of the 
same form as in Hesperophanes, being dilated and 
rounded at the sides anteriorly. The whole insect is of 
a reddish-brown colour, and covered with rather coarse 
erect grayish pubescence; the elytra are uniformly punc- 
tured, with a faint raised line from shoulder to apex ; 
the head and thorax are coarsely rugose-punctate, or 
scabrous. The abdominal segments are normal in both 
sexes ; the apical ventral plate being truncate in the 
S , and rounded in $ . The antennae are of the length 
of the body in the S , and two-thirds the length in the 
$ , with the third joint about one-third longer than the 
fourth, and much shorter than the fifth.
