THE ENTOMOLOGIST. 109 



Harpalus attenuatus. — Stephens's name is indeed anterior 

 by a year to Dejean's, but his description is quite irrecog- 

 nizable, buried as it is among a mass of imaginary species ; 

 he also described it as H. picilabris : hence Dejean's name 

 should be retained. 



Stenolopus dorsalis. — The French authors consider S. 

 brunnipes as a mere dark form of S. dorsalis, an opinion in 

 which I decidedly concur ; but the Azorian species, ranked 

 as brunnipes by M. Morelet, is very distinct. 



Bradycellus rufulus, Dj. — Duftschmidt's name, brought 

 forward by Dr. Schaum, appears to me very doubtful. He 

 probably mixed more than one species, and certainly Dejean 

 was the first to clearly separate the three ; hence, if he did 

 not adopt any of the earlier names, we cannot alter his. 

 Marsham's name, besides being valueless as far as his de- 

 scription goes, is already preoccupied. 



B, collaris. — I believe we have true northern exponents of 

 this species, but the intermediate forms of B. harpalinus are 

 so close that I can only consider them races of one species ; 

 indeed I am far from satisfied with the distinctions between 

 the preceding species. 



Trechus minutus. — T. obtusus, Er., appears to me a more 

 alpine form of T. minutus ; indeed even in. the low grounds 

 T. minutus strays into the obtusus form. Its apterous con- 

 dition is additional confirmation of this. 



Perileptus. — The genus Blemus was not characterised 

 by Ziegler. Stephens first gave its characters, and made it 

 include our Trechus ; hence a new name became necessary 

 for B. areolatus. 



Bembidium biguttatum, F. — This species divides well into 

 two forms ; one 2^ lines long, common in N. Europe, and 

 doubtless the one first described by Paykull (1790), to which I 

 have restoi-ed his name ; the other smaller and very like Bem- 

 bidium gutiula, differing from the former by the seventh stria 

 of the elytra being distinct. B. aeneum, Germ., may also be 

 ranked as a coast form of this species, to which it bears much 

 the same relation that B. Mannerheimii does to B. gutiula. 



B. assimile, Gyl. — Bembidium Clarkii is apparently at 

 once distinct from this species, but the characters shade oflF 

 almost imperceptibly ; certainly I have seen leads which
