saw; the head and thorax were orange, the shoulders (or base of elytra) black, 

 round the waist a broad sash of brilliant scarlet, below that another band of 

 black, then a band of grey-white, and the tips of the elytra black. In two all- 

 day visits to this place I caught five of these beetles, three of them red- 

 handed — one on a stump with an ant in its jaws, a third on a fence-post 

 dissecting a grub of some kind, the other two belonged to the blameless 

 order of those who have not yet been found out. One was resting on a rail 

 along which a stream of ants happened to be crawling, and the fifth was just 

 issuing from an ant bore in a dead pine, down which motives of curiosity, 

 doubtless as innocent as idle, had prompted it. The same impulse, I think, 

 rather than any misgivings about my intentions, caused it to disappear down 

 an adjoining tunnel, whence my forceps finally extracted it. 



In the season just over (1908) I noticed some felled maple and birch on 

 a hillside 7 miles from Port Hope. At the beginning of June I laid chips 

 about two or three of the stump heads ; on the fallen trunks I found an 

 immense number of Chrysobothris breeding, while under two of my chips 

 on the maple I took two pairs of Urographis fasciafa, and resting on a stump 

 near by I captured a Leptura biforis. 



About the middle of June my attention was drawn to some white pine 

 felled in the winter among some woodlands, known locally as Pine Grove. 

 There were about eight trees in all, lying on the ground within a space of 

 about a mile. On the trunks and branches were crawling a number of small 

 dark Clerids with a mark of crimson and two marks of white on each elytron ; 

 there was also two sorts of weevil abundant under chips of wood on the ground, 

 and many Buprestids visiting the logs; but in especial, on the trunks, limbs 

 and larger branches there were Monohammi breeding. In about six visits I 

 took well over 100 specimens, and my fellow-collector continued to find longi- 

 corns up to the 20th of July or later. Our combined captures would amount 

 to 250 beetles. The great majority of these were Monohammiis scuteUatus, 

 of which I took 100, mostly in pairs. I took besides 8 or 10 specimens of 

 the large grey Monohaminus (whether titillator or confusor, Fig 14, I am 

 not sure), and four of both sexes of the rust-yellow species. We also got 

 several specimens of a stout grey beetle resembling Urographis, but without 

 the extended ovipositor, and a few of a grey species of delicate structure and 

 extremely fine antennae (pferhaps Tjiopus). About the middle of July my 

 friend took some 12 specimens of Lcptostylus parvus.. All this on some ten 

 trunks of newly-felled pine. 



Our experience raises a question as to the length of time required by 

 the larvae to mature. There was a tree among these others that had been 

 blown down early in 1907, and was thus ^n its second season. It was full 

 of holes, most of them quite fresh, from which mature insects had escaped. 

 We could hear larvse at work during June inside the log, but we did not 

 see any beetles breeding or laying eggs on the bark, as they were doing on 

 all the fresh-fallen trees. Unfortunately, most of these trees ^ave since 

 been removed. I am inclined to think that the dryer the wood is, the longer 

 the larva takes to reach its full growth, and that if the larva hatches in 

 fresh wood it can mature in a single season. I should think this was true of 

 the sruteUa'tus, anyway, even if confusor and titiJlator require longer. The 

 well-known stories, most of them authentic, about the mature insect escaping 

 from tables and chair legs several years after the manufacture of these 

 articles, would thus illustrate an exceptional state of things in which the 

 larva was confronted prematurely with drv wood to feed on. 



Besides these captures on stumps and logs, I have made several bv 

 using a similar trap with fungus substituted for bark. But at present I shall
