310 THE entomologist's record. 



Aulonium sulcatum, Oliv. (trisulcum, Fourc.)> a species of Colydiid 

 Coleoptera new to Great Britain. 



By C. J. C. POOL. 

 I have much pleasure in introducing this rare beetle to our list of 

 indigenous coleoptera. On July 13th last, at Enfield, I found the 

 insect in all stages, inhabiting the burrows of Scolytus multistriatus, 

 Marsh., in elm bark. Two other species, Scoh/tus destructor, 01., and 

 Hf/popMoeiis hirolor, 01., were found in the same post, which is a por- 

 tion of a prostrate bough, to be seen about two hundred yards away. 

 The specimens at first taken were immature, so I kept them alive for 

 several days. Mr. W. E. Sharp came here on a visit shortly after, 

 and together we went lo the post, from which another specimen was 

 taken. Mr. Sharp took this specimen home, and I am indebted to him 

 for recognising the insect as belonging to a genus not yet included in 

 our list, and on my forwarding a specimen to the Natural History 

 Museum Mr. Arrow identified the same as Anloniinn siilcatuvi, Oliv., 

 of which there are specimens from France in the museum collection. 

 It may appear to be strange that the insect should for so long escape 

 detection, but I think this is due to its rarity, as well as to the fact 

 that, as a hunting-ground, Enfield does not appear to have been dis- 

 covered by many coleopterists. The spot where it has now occurred 

 would have been unapproachable a short time ago, but owing to build- 

 ing operations now going on I have been able to work at a number of 

 fine old trees, which are doomed to destruction at an early date. Many 

 dead elm trees and posts are in the vicinit}', all showing very distinctly 

 the result of the ravages of long past generations of Scolytus multris- 

 triatiis, etc., making it an ideal spot for the habitation of the Auloniiou, 

 which is recognised as being parasitic upon the species of Scoltjtus. 

 It would perhaps be interesting to mention a few of the beetles I have 

 found this season within a quarter mile radius of the same post : —

 de))ia (jiiadripKstulata, Marsh., Hallnmenns humeralis, Pz., and some 

 exceptionally large examples of Dornis parallelopipediis, L. This list 

 is sufficient to illustrate the fact that Enfield contains a spot which at 

 present is very rich in good beetles, and that a splendid hunting- 

 ground is about to be sacrificed to bricks and mortar. In a few years 

 time, or perhaps months, there will be commenced a new line of trams 

 connecting Enfield with the great metropolis, and some day, when 

 seated on the roof of a County Council electric car, I may sorrowfull)^ 

 point to an oft" licence public-house occupying the spot where once 

 occurred Auhniimn fudcatuw.
