6G THE ENTOMOLOGIST. 



the faunas is greatly increasing, especially as we constantly 

 find more of his species, and, when once attention is directed 

 to them, no doubt nearly all will turn up. I am greatly 

 indebted to M. Thomson for sending me nearly all his new 

 species to examine, and expect a further contribution shortly, 

 as he tells me he has described several species recently. 

 Bembidium Sahlbergii, Zett., is identified with our B. 

 Schuppelii. B. geneura is considered as a variety of 

 B. biguttatum. 

 ^•Epus marinus, Strom., has never been found since 1783 ! 

 Pterostichus cupreus is divided into two s})ecies : — 

 P. puncticeps. Larger ; forehead punctate ; posterior tibiae 



with about ten setaj. 

 P. pauciseta. Smaller ; forehead smooth ; posterior tibiae 



with about six setae. 

 Both these occur in England : the latter is probably our 

 old P. versicolor. 



M. Thomson maintains the distinctness of Anchomenus 

 viduus, moestus and eraarginalus, and enumerates their 

 differences. 

 Hydroporus hyperboreus is sunk as a variety of H. assi- 



milis, Pk. 

 H. Boheraani is identical with our H. oblongus, Steph. 

 H. pubescens M. Thomson considers to be the true nigrita, 

 Gyll., and nigrita, Er., he considers to be pubescens, 

 Gyll.; hence the names are interchanged. 

 H. glabellas is a new species, near H. pubescens, Gyll. 

 (nigrita, Er.), and is not rare in England ; but there 

 is some confusion here amongst nigrita, discretus and 

 glabellus, that is not yet unravelled. 

 Hydaticus transversalis is split into two species, only one 

 of which can I find in my collection ; others may probably 

 be more lucky : — 



(1). H. punctipennis. Elytra punctate, especially towards 

 the sides ; the yellow margin with black lines down 

 it ; the four anterior tibiae ferruginous. 

 (2). EJ. laevipennis. Elytra smooth ; intermediate tibiae 



piceous. 

 Ilybius 6-dentatus is regarded as a variety only of I. ob- 

 scurus. I have noticed that they rarely, if ever, oecuir 

 together.
