THE CANADIAN ENTOMOLOGIST. 445 



lliere I turneJ him loose. \Vhile I was looking about, with my eye 

 focussed for beetles, I distinctly saw a pair of longicorns running on the 

 trunk of a tall elm growing at the foot of the clearing near the stream. 

 From their movements and appearance both I felt sure they were longi- 

 corns, and at first took them for a pair of Cyrtopliorus verrucosus, a beetle 

 I am well acquainted with; an instant's reliection told me that at ten yards' 

 distance a beetle the size of Cyrtophorus would hardly be visible, and I 

 rushed towards what I was certiin mu^t be a prize; unfortunately, the 

 beetles were running in an upward spiral, and when I stumbled to the tree 

 over a rotten log they were almost out of reach ; I jumped and managed 

 to brush one to the ground, but could not see it by the most careful 

 search ; however, I waited patiently for a minute or so, and then, to my 

 great delight, saw the creature emerge from the ground and reascend the 

 trunk. As I captured it I recognized in it the Physocnemum brevilineum, 

 a long-coveted species. Scanning the tree carefully, I presently descried 

 two more of the beetles running about on the bark, some 20 feet up; I 

 stayed for nearly an hour at the foot of the tree, with hope in my heart 

 and a crick in the neck, as intent as a dog listening to the chatter of a 

 squirrel, and my reward was three or four specimens of the beetle. As a 

 rule, they appeared from a height beyond range on the trunk of the tree, 

 walking rapidly downwards, following the corrugations and grooves of the 

 bark ; occasionally, however, they lit on the tree after flight tlirough the 

 air, but they rarely when disturbed took to the wing for escape, preferrii-g 

 to run or to release their hold and drop. A six-mile walk is nothing when 

 a new longicorn is waiting just round the last corner, and I made the tree 

 the turning-post of my daily course for nearly a week, by which time I had 

 taken 15 or 16 specimens. The tree was apparently sound, with a mag- 

 nificent crown of foliage surmounting the massive pillar of its trunk, but 

 the beetle was breeding there, I am pretty sure, and in ]v\\y of this year, 

 while I was in England, my fellow-collector got several more specimens 

 on the same tree. 



Early in July I made an expedition to Garden Hill, some 10 miles 

 north of Port Hope ; here they were cutting out the pine from a 20-acre 

 lot, and a sawmill was at work. I went out in hopes of getting some 

 specimens of MonoJuDiimus, a beetle that, with a single exception, I knew 

 only from cabinet collections. The lumbermen said they had seen num- 

 bers of these insects on the logs and in the brushwood, but from inex- 

 perience or ill-luck I failed to secure many ; my bag included one pair of
