of notice from Achill is Zaccobiics regularis of which I found one male specimen. 

 It is quite readily recognised from the other Laccobii which come near it by 

 the aedeagus. This species was first recorded as British by Dr. Sharp 1 from 

 Brockenhurst and he mentions having seen specimens from Surrey. It has 

 since been recorded from Berks and South Devon, 2 and these are at present 

 the only known British localities. It was first introduced under Motsehulsky's 

 name but, owing to the vagueness of that author's description, Bey's name 

 has since been adopted. 



The Achill Island list, including all records, amounts to forty-four species 

 and is as follows : —
