74 THE CANADIAN ENTOMOLOGIST 



yellow, but in the stranger the hind margin is also yellow; both have a yellow 

 scutellum and a small patch of yellow at the base of each wing-cover; but the 

 familiar long "L"-shaped mark of yellow behind this in Clytanthiis ruricola is 

 replaced in the stranger by a simple diagonal line slightly curved, and behind 

 this is a transverse band of yellow continued across the sutural line over both 

 elytra. The thighs of both insects are clavate, but in C. ruricola, only, are the 

 hind thighs and tibiae elongate; in the stranger they are even shorter than in 

 Xylotrechiis and more strongly clavate. The insect has been identified as 

 Clytus marginicollis and is, I believe, a great rarity in Ontario; at any rate, it 

 is a new species and a new genus in my collection, filling an important gap in 

 the group of Clytini. 



It was quite enough for me that I had been collecting Longicorns for 15 

 years and had never seen this insect before. There lay my friend, inert as the 

 weariest of mere wayfarers without an object could possibly be on a sizzling 

 hot day; but my capture filled me at once brimful of activity and fervour. I 

 spent a good half hour peering about that pine trunk and its limbs in the hope 

 of another capture, and even when we decided to move on, I was still straining 

 at the leash, eager to beat the next cover for game. 



Just west of Hume's old home-farm is a sloping hillside covered with small 

 trees and intersected by streams of cress-mantled spring water. At one of 

 these I stooped to drink, for a long draught is worth far more to the pedestrian 

 on a hot day than solid food of any kind. While thus refreshing myself I observed 

 on the further bank a recent windfall of basswood; "windfall," I call it, but it 

 might almost have been called a "water-fall;" for its roots had been under- 

 mined by a freshet, and a sudden fiaw of wind taking it by surprise had over- 

 turned it. It was while struggling up the further bank, with one eye glued on 

 the basswood, that I caught sight of a specimen of Neodytus erythrocephalus 

 running along a limb on the oiY-side of the fallen tree. As soon as I got to the 

 top of the bank I hurried round the head of the tree to where I had seen the 

 insect. There it was again! but unfortunately hurrying down towards the axil 

 of a large limb impossible of approach owing to the thicket of grapevine into 

 whose midst the tree had crashed. However, I kept the insect in view, and 

 presently to my relief it faced about and came up towards the smaller branches 

 at the top of the bank. And here after a little anxious stalking, 1 made my 

 capture. Next moment I saw the dead image of it, very much alive, hurrying 

 along the limb again; had it escaped from the cyanide jar? No, there it was 

 safe in the glass bottle. Again I stalked my quarry, and again I made my 

 capture; and presently, behold a third, running along the trunk. Where the 

 insects came from I could not discover, but it seemed certain that they arrived 

 by aeroplane and became visible only on alighting. Some time after, I spied a 

 fourth, but it managed to elude the eager clutch of m\- lingers, as it had the jaws 

 of my forceps and the yawning gape of nn- net; no sooner did it take to flight 

 than it \anishcd into thin air. 



In its descent the tree had broken some shoots of sumach at the top of the 

 bank;close to these, but nearK under the basswood and in neutral territory on 

 the ground, 1 captured a beautifully marked grey-brown Lamiinid which proved 

 to be Lepturges symmctn'nis; some days later, nu- friend took a second specimen
