here, though very common in Enrope generally, while O. 

 liqiiidus is peculiar to tlie South-West. 



Cercus pediciilarius. — Almost the only difierence given 

 between this species and C. bipustulatum is the length of the 

 elytra, and even this does not hold. The extremes look very 

 difierent, but many specimens will be found almost inter- 

 mediate. 



Nitidula obscura. — The Silpha rufipes of Linneus corre- 

 sponds with N. obscura, according to his collection, but the 

 great proportion of authors refer it to Meligethes rufipes. 

 The description would suit either, but it cannot be retained 

 for both. 



Meligethes ochropus. — Mr. Rye informs me that Mr. 

 Waterhouse has specimens similar to my own, and that they 

 do not agree with the types of Erichson's species. I have 

 therefore added a note of doubt to the identification. 



M. Marrubii, Bris. (Cat. Col. Fr. 54, 70). — About the size 

 and form of M. serripes, but at once known from any of our 

 species by the armature of the intermediate tibiae, which have 

 very strong setae, giving them the appearance of the anterior 

 ones. One specimen at Weston. 



M. ebeninus, Frst. — This species evidently belongs to 

 the lugubris group, but is very distinct by its sparse punc- 

 tuation and very black appearance : I have only seen two 

 females as yet, hence cannot identify it with certainty with 

 Forster's species. 



M. obscurus, Er. — Nearly resembles M. erythropus, but is 

 larger and with dark legs. Two specimens from the North. 



Cerylon angustalum, Er. — Stephens appears to have de- 

 scribed one of the red species imder the name of ferrugineum, 

 but Erichson, being unable to identify it with any one of his 

 three in particular, was obliged either to pass it over or to 

 apply it arbitrarily. He preferred the former, and I conceive 

 that we are bound to follow him, as Stephens certainly did 

 not know C. angustatum, Er., as a species, though lie may 

 have had it to represent his ferrugineum. If, indeed, only 

 one form had been found in this country, there might be 

 more show of reason ; but we have certainly two red species, 

 if not more, which Stephens failed to recognise. 



Monotoma angusticollis. — The above change is adopted 

 from Thomson, who shows that Aube mistook Gyllenhal's
