18 THE REPORT OF THE No. 36 



On May 24:th, while at Lake Catehacoma, some 30 miles north of Peter- 

 borough, I found an extraordinary number and variety of insects drawn in the 

 hot sun to the choke-cherry clusters; besides about 10 species of Longicorn, there 

 were a large number of species of Chrysomelians, Scarabs and Elaters; among 

 these last, three species of Corymhites including ('. hamatus and C. vernulis; 

 but the most interesting by far to me of the day's bag was a pair of the very 

 handsome Cantharid, Pomphopoea aenea. Only once before had I ever seen this 

 insect, and that was at Port Sydney towards the end of June, when I found a 

 pair on the Nannyberry {Viburnum lentago). It is a large insect of a beautiful 

 grey-blue-green shade and of satiny texture; the antennae black, and the legs 

 orange-yellow with black knees and feet. Of the species I am not quite sure ; 

 Dr. Bethune who kindly identified the earlier capture thought it P. saiji, but 

 according to Blatchley the yellow and black legs belong to P. aenea. This had been 

 1909, for it was just a few weeks before Dr. Brodie's death, with whom I was 

 staying in North Muskoka at the time. 



On the first of June I captured two specimens of the so-called Currant-borer 

 {Psenocerus supernotatus) settling on a newly fallen poplar stem. On June 10th 

 while ranging about a tamarac swamp for Pyrola and Cypripedium, I had the 

 good fortune to capture a breeding pair of Tetropium cinnamopterum resting in 

 the shadow on the underside of a recent windfall of white spruce, the only tree 

 I have ever captured this insect on. On June loth — rather an early record — 

 while foraging about at the " Wood of Desire," I spied a specimen of Desmocerus 

 palliatus, flying from a small clump of the late elder; examination of the shrubs 

 led to the capture of a dozen of these handsome borers; they had evidently just 

 emerged and were crawling up into the sunlight from the stems, a few were 

 already pairing and taken at rest on the underside of the foliage. A specimen 

 of Goes oculatus was taken the same day on newly fallen poplar. On June 18th, 

 while exploring a very rich corner of tamarac swamp, I made two finds especially 

 that awoke happy memories; after an interval of 19 years, I found again that 

 local rarity among the orchids, Orchis rotundifolia, and on the swamp Valerian — 

 just as three years before near Trenton — I found l.eptura chrysocoma feeding on 

 pollen. Between June 18th and 20th, I took three specimens of this beetle always 

 among tamaracs. On June 25th, I captured a specimen of Saperda tridentata on 

 an elm log, and on a large billet of poplar in a woodpile, a pair of Pogonochaerus 

 mixtus. 



On June 29th and 30th, during a short stay in Port Hope, I paid a visit 

 to some woods four miles north where a season or two l)efore the woodman's axe 

 had been very busy — far too busy, for every windstorm since has taken heavy 

 toll of the surviving timber. The work of tramping in hot sunshine through 

 bush, and stumbling or slipping on hidden logs and stumps was very exhausting, 

 but a number of interesting captures were made. Among these, one Leptura zebra 

 on the sheaf of foliage about an oak stump, five Neodytus erythrocephalus taken 

 running on the trunk and limbs or two fallen trees, a basswood and a butternut, 

 one Clytus marginicollis on white pine, three Physocnemum brevilineum on 

 fallen elm, three Leptostyhis sex-guttatus in brush-heaps of white pine,^ one 

 Leptostylus macula on basswood, one Goes oculatus and one Urographis fasciatus, 

 both resting on the underside of a lodged trunk of maple, three Iloplosia nubila 

 on basswood, two Lepturges symmetricus and one Eupogonius s'ubarmaius on a 

 recent windfall of basswood. 



On July 4th a trip from Peterborough to the " Wood of Desire " proved very
