times biguttattis on one side, and 4e-punctatus on the other, which appears conclusive. 

 Dawson (Geod. Brit., p. 57) eays, that it is probably only an uncommon variety of 

 N. semijmnctatus, Fab., of which he makes N. liffuttattis a variety. I have specimens 

 from the south of England which show no structural difference from N. higuttatus 

 worth mentioning ; the striae, however, on the forehead appear to be more numerous i 

 and finer than in this latter species. * 



Carahus atiratus, L. 



The specimens of this insect that from time to time are captured in this country, 

 seem to bo always taken in situations or localities that make it almost certain they 

 have either flown across the channel, or been imported with vegetables, &e. 



Caeabus cakcellatus, 111. 



This species has been alternately inserted in and omitted from the list. Dr. 

 Power tells me that there are certainly two or three well authenticated specimens, 

 and that he thinks one has been taken within the last two or three years ; among 

 some notes from Mr. Mason relating to Mr. Eye's collection, I find this insect men- 

 tioned as one that ought to be re-instated. 



Carahus convexus, Fab. 



The only specimen of this insect that seems to have any good claims to authen- 

 ticity is in the collection of the Rev. A. Matthews, and this rests on rather circum- 

 stantial evidence. 



Calosoma sycoplianta, L. 



This species is almost certainly not indigenous ; it is only an occasional visitant 

 from the continent. 



Dyschirius ohscnrus, Gyll. 



I have never seen this species. Dr. Power says that he believes it rests on one 

 specimen, which he always thought was a varying specimen of some other species, 

 and he advises its omission from the list. Dawson (Qeod. Brit., p. 29) says, that 

 M. Putzeys had informed him that M. Reiche had a specimen which was captured 

 in England, and that Mr. Haliday had told him he had captured it on the shores of 

 Lough Neagh. In Ent. Ann., 1858, 51, he alters his description, as given in the 

 Geodephaga Britannica, saying, that he was now able to describe it from actual types 

 before him ; he does not, however, say whether these types were British or foreign 

 examples. 



J3rachimis explode7is, Duft. 



This appears to be a doubtful species ; the whole question will be found dis- 

 cussed at length Ent. Ann., 1866, 58. 



Deomius tectensis, Eye. 



This species is closely allied to D. sigma, Eossi, but is distinguished by its 

 shorter and stouter antennae, wider head, and more transverse thorax, and wider and 

 comparatively shorter elytra ; the shape of the fasciae on the elytra also serves to 

 distinguish it. It frequents the sea coast, especially in the Isle of Wight, whereas 

 2>. sigma is a fen insect (Ent. Mo. Mag., x, 73 ; Ent. Ann., 71, 76). i
