and the other much longer on the posterior part of the 

 elytron. The antennae 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 Ohrium, 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 tlie 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.
