Bu. Betulfe. Steph. Catal 163. No. 1661.

 thorax witli a slight transverse impression in front, and a small impressed 

 fovea towards the middle of the base, on each side ; the disc rather obsoletely 

 punctulate, with a faint dorsal line and the lateral margins flavescent: scu- 

 tellum whitish: elytra delicately punctate-striate, varied with irregular un- 

 dulated, flavescent, pilose fasciae : legs rufo-testaceous, with the femora clavate, 

 and each with a rather obsolete tooth : antennae long, rufo-ferruginous. 



Slightly variable in colour, and in size:— 1 have retained the name which I ap- 

 plied to this insect several years since, although it has been previously described 

 by Herbst, by the name of Rh. Cerasorum ; but as Fabricius has also described 

 an insect by that name, (v,'hich he states is English — one of the foregoing 

 insects—) and his name has probably the priority, the present appellation 

 will therefore prevent confusion ; and Herbst's name is obviously inapplicable, 

 as it resides upon the birch. 



Rare: in June, 1S16, I met with several examples on a birch in 

 Coombe-wood, where it has once or twice occurred since. " Lord 

 Spencer's park, near Wimbledon." — Mr. G. Wuterhoiise.
