tinctus ; they are distinctly narrower than the tibiae, while 

 in distinctus they are scarcely so. 



Antennse rather short, a trifle longer than in distinctus ; 

 length of flagellum 5^ mm. The 3rd joint of the antennae 

 is shorter than the 5th. 



Armature distinct. Tips of the forceps blunter than 

 in vestalis and distinctus. 



Ps. barbutellus is parasitic on B. hortorttm. 

 Although widely distributed, it is not very common 

 in most places. At Ripple it is never so abundant 

 as Ps. ritpestris and Ps. vestalis. In Ireland it has 

 been recorded from Co. Kerry, Co. Dublin, and 

 Co. Armagh.
