Pilose, black : elytra punctate-striate, with the base rufous, the apex black, 

 with an incurved white fascia a little behind the middle, frequently abbreviated 

 towards the suture : antennae and legs black. 



I once met with three fine specimens of this beautiful insect on 

 some new oak paling, at Hertford, in June ; and saw others, but 

 was unable to secure them from their great activity : it has also 

 been taken not unfrequently near Windsor. 



Genus CCXLV. — Opilus, Latreille. 



Antenna? pilose, clavate : the second joint short ; the six following elongate ; the 

 remainder forming the club, of which the basal joint is elongate obtrigonate, 

 the others shorter ; the terminal one being obliquely acuminate. Palpi with 

 the terminal joint large, securiform : head as broad as the thorax, which is 

 conic-cylindric, with the base slightly attenuated : body elongate : tarsi in- 

 distinctly five-jointed, the basal joint being minute and concealed above by the 

 apex of the tibiae. 



The elongated intermediate joints of the antenna?, which are 

 gradually incrassated from the base to the apex, the securiform ter- 

 minal joint of all the palpi, and simple eyes, are the principal 

 distinctions of this genus : the larvae and imago are both found be- 

 neath the bark of trees, and occasionally feed upon other insects 

 in the imperfect states.
