propriety of placing it as a new genus, near Tarsostenus ; the 

 antennae have the last three joints slightly enlarged and more 

 approximate than in Clerus sanguineus. The last joint of the 



labial palpi is very large and dilated ; the maxillary palpi cannot 

 be seen.

Two specimens, from Nebraska, given me by 31 r. Ulke. Larger 



than the largest specimens of H. humeralis, and readily distin- 

 guished by the less coarse punctures of the elytra, and by tin- 

 extremely coarse silvery pubescence, which, on the elytra, is 

 directed both longitudinally and transversely; just behind the 

 middle there is a transverse band in which all the hairs arc 

 directed outwards: a similar space, though less obvious, is seen 

 at the base, extending one-third the length along the suture
