Nov. 1866. 

 Mr. Sharp states that the insect which he attributes with 

 doubt to this species (on account of his inability to perceive 

 in it the character specified by Thomson as to the position of 

 the hinder frontal setae, which should be nearer to the neck 

 than to the eyes) is distinguished from varieties of Q. ful- 

 gidus with red elytra by the entirely black colour and shorter 

 articulations of its antennce ; also that Dr. Power has long 

 recognized it as specifically distinct from Q. fidgklus, which 

 occurs in cellais and outhouses, whilst the above insect is 

 found under bark and at ths sap of trees. This locality test 

 cannot, of course, be much relied upon ; in my own limited 

 experience I have never found Q.falgidus in either cellars 

 or outhouses, but often about trees.

Recorded (amongst other localities) from Ireland by Herr 

 Scriba (loc. cit.), who states that it may be known from 

 P. carhonarius, Gyll., by its more slender antennae, of which 

 the penultimate joints are as long as broad, and by the sixth 

 abdominal segment of the male not being emargina'te 

 beneath. 



The usual confusion attending insects of the P. ceneus 

 group is here shown ; inasmuch as the very characters given 

 by Herr Scriba to distinguish his insect from P. carhonarius
