Pilose; rufous: head black: thorax rufous, with the anterior margin black: 

 elytra rufous at the base, the rest black, with two transverse snowy-white 

 villose fasciae, the anterior one slender and flexuous before the middle, the 

 other broad, and more or less angulated anteriorly behind the middle: legs 

 black : tarsi piceous : antennae piceous black, the terminal joint of the latter 

 ferruginous at the tip. 



With the thorax beneath and breast black: — this variety appears rare. 



Not common : I have taken it at Coombe-wood, in April ; and 

 I believe it has been captured in other places in its vicinity, in 

 June : it is said to be partial to trees of the fir kind. " Windsor."

Genus CCXLVII. — Clerus, Geoffroy. 



Antennae slender, and submoniliform at the base ; the three terminal joints 

 abruptly larger, and forming an obtriangular club, the apical joint of which 

 is very large, rounded and acuminated on the inner edge. Palpi, maxillary 

 filiform : labial short, securiform : eyes notched : thorax conic-cylindric : tarsi 

 indistinctly five-jointed, the basal joint being minute, and not visible from 

 above. 



The insects of this beautiful genus are distinguished by having 

 the three terminal joints of the antennae incrassated, and the last 

 with an acumination within, by the eyes being notched, the 

 maxillary palpi having the terminal joint obconic, and the labial 

 ones securiform. 



The larvse inhabit the nidi of bees, to which useful insect they 

 are very destructive : the perfect insect is found on flowers.
