NEW BRITISH SPECIES NOTICED IN 1856. 79 



apparently consisting of ten joints only, the eleventh being 

 widest at its base, nearly hemispherical, and so closely 

 applied to the apex of the tenth as to be not very readily 

 distinguishable ; the capitulum or club has thus the appear- 

 ance of being solid or uni-articulate, whereas in Teredus it is 

 distinctly bi-articulate, the eleventh joint being much narrower 

 at its base than in the middle, globose : in Oxylcemus the 

 prosternum is produced, forming an acute triangular pro- 

 jection beneath the head, not present in Teredus.

A single specimen only of this species has come under my 

 notice, it was captured by Mr. Edward Sheppard, beneath 

 bark of oak, near Lyndhurst.

 Of all the additions made during late years to our list, the 

 present is perhaps the most interesting, and to it I beg to call 

 the earnest attention of those who are pursuing the important 

 subject of geographical distribution. 



Three specimens of this insect have come under my notice. 



The first taken by my assiduous and successful friend Mr. 



T. P. Dossetor, on the 6th of October, 1850, at Colney-hatch, 



Middlesex, crawling up the trunk of an oak, within a short 



distance of a fungus, whither it was probably on its way.
