106 THE ENTOMOLOGIST. 



and N. palustris is accurately furnished by N. lalicollis, Chd.^ 

 and N. Germinyi, Fr. ; indeed I have seen intermediate spe- 

 cimens in this country. 



Notiophilus 4-punctatns. — The impressed points on this 

 species vary, being occasionally absent on one side ; but other 

 slight differences in sculpture confirm its claim to be con- 

 sidered a special form of N. bigutlatus, and not a mere sport : 

 thus the sculpture of the thorax differs, and the striae of the 

 elytra are finer and less punctured. 



N. substriatus. — The type-form, N. geminatus, Dej., is 

 found in S. Europe, ^nd differs in having the frontal striae 

 more numerous and the elytra unicolorous ; whereas in our 

 form they have always a yellow spot at the apex. 



Calosoma Sycophanla certainly occurs in England, but I 

 cannot conceive that any doubt can exist as to its having 

 been accidentally introduced in every instance. 



Carabus. — Whether all the records of Carabus auratus are 

 to be believed, and, if so, whether they indicate more than an 

 analogous tendency to accidental occurrence, is open to 

 doubt. For C. cancellatns the evidence appears to me more 

 slight ; but, besides tlie original ones, two examples have 

 occurred, one recently, and are certainly authentic. C. cou- 

 vexus, I think, is most probably British : Mr. E. S. Saunders 

 has an example purporting to come from Ireland. It cer- 

 tainly might be overlooked, if as local as C. intricatus ; but 

 even this could hardly be said of the others, and they would 

 be readily introduced in ballast, &c. 



Brachinus explodens. — To put this and Lebiahaemorrhoida- 

 lis in Italics, after the careful discoveries of Mr. Sidebolham, 

 must seem at first very much like a deliberate insult to that 

 gentleman. I feel sure, however, that he will not view it in 

 that light, especially as -I have striven to mete out the same 

 measure to myself in re Eu. sticticus. Sit. gressorius, &c. 

 The fact is that before a species can be fairly registered as 

 British it must be shown to have some sort of metropolis 

 where it can be found, though perhaps with difficulty. So 

 many isolated things have occurred which time has not con- 

 firmed, that one is led to doubt these casual occurrences 

 perhaps to too great a degree. Admitting perfectly that this 

 species and Lebia haemorrhoidalis were taken in Britain, it 

 does not nevertheless, in my opinion, stamp them as being 

 certainly British insects.
