IN our standard work upon British beetles and in our cata- 
logues there are five species of Deronectes, of which one is 
given as Deronectes depressus, F., sometimes with elegans, 
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 kept very few 
specimens. These, however, all prove to be what I will 
call the northern species, and all other Irish specimens I have
