 logues there are five species of Deronectes, of which one is 

 given as Deronectes depressus, F., sometimes with eUijans, 

 Panz., as a synonym. . 



Under this name we have two species mixed in our collec- 

 tions, and these two species, although easily confused, are 

 really distinct, and with a little experience easily separated. 



One of these is common throughout England and Scotland, 

 while the other seems to be limited in its distribution, being 

 confined, so far as I know at present, to Scotland and the 

 north of England and to Ireland, where it is apparently the 

 only one found. My uncertainty as to Ireland rests upon 

 the fact that before I knew of the existence of these two 

 species I had ^^ depressus" in my records for most parts of 

 that country — for twenty-four out of the thirty-eight county 

 and vice-county divisions, — but I had actually kipt very few 

 specimens. These, however, all prove to be what I will 

 call the northern species, and all other Irish specimens I have
