Cerambyx notatus, Drury, App. vol. 2. 



Habitat : See Observation below. 



Head grey brown. Antennse grey brown, and about the length of the insect. Palpi four, and just 

 above the mouth are placed, on each side the head, two protuberances. Thorax grey brown, dappled 

 with black; having on each side a short thick spine. Scutellum small and triangular. Elytra grey 

 brown, dappled with small black streaks, and extending beyond the anus. Abdomen, breast and legs 

 grey brown, like the rest of the insect. 



The insect figured by Drury is stated to have been received from Norviray. No Longi- 

 corn beetle, corresponding with Drur/s insect has been ascertained to be a native of that 

 country, or indeed of Europe. Hence, as this figure very nearly corresponds with the 

 American Lamia dentator of Fabricius, I am inclined to believe that Drury's specimen had 

 been imported from North America, in the same manner as the specimen described and 

 figured by Mr, Haworth in the Transactions of the former Entomological Society, and 

 which was taken near London. I have, however, marked the spionyms with doubt, this 

 figure having been overlooked by all subsequent authors.
