66 COLEOPTERA. 



references to authors, and lists of synonyms ; enough^ how- 

 ever, is given for practical purposes, and the room saved has, 

 I trust, been made generally useful by giving distinctive 

 characters, as often and as fully as possible. In these 

 latter I have endeavoured to use the words of the original 

 recorders. 



1. Blechrus GLABRATUS, Dufts. ; Dcj. ; Waterhouse Cat. 



Brit. Col. 



This species must be erased from our lists. It was intro- 

 duced on the supposed authority of the Stephensian col- 

 lection ; I have, however, examined the insects bearing the 

 name glahratus in the latter, and can come to no other con- 

 clusion than that they are all Metahletus truncatellus. 



The Bleclirns found in England so commonly is wiawr?/.s', 

 Sturm; it is smaller thnu glahratus , Dufts., entirely jetty 

 black and shining, with the head smaller and thorax a little 

 more contracted behind ; the elytra, moreover, in glahratus 

 are even more parallel than in this species. Both Fairmaire 

 and Dawson have considered the two as identical ; however 

 this may be, the insect known ^s glahratus, Dufts., appears to 

 belong to Southern Europe. 



2. Dyschirius ELONGATULus, Dawson; Wat. Cat. 



Mr. Waterhouse is inclined to believe tin's is the D. 

 extenms of Putzeys (Monographic des Clivina, &c., p. 40, 

 sp. 49) ; but our insect is not the same as that described by 

 Dr. Schaum in his Ins. Deutschl. under the latter name, as 

 Dr. Schaum has kindly allowed his type specimen to be 

 compared wnth our British insect. 



Examples have recently been taken by the Rev. H. Clark 

 at Deal ; the species, however, appears to be as rare on the 

 continent as here.
